    I really hope this doesn't hinder development too much. As Simon says, Qwen3.5 is very impressive.

    I've been testing Qwen3.5-35B-A3B over the past couple of days and it's a very impressive model. It's the most capable agentic coding model I've tested at that size by far. I've had it writing Rust and Elixir via the Pi harness and found that it's very capable of handling well defined tasks with minimal steering from me. I tell it to write tests and it writes sane ones ensuring they pass without cheating. It handles the loop of responding to test and compiler errors while pushing towards its goal very well.

      I've been playing with 3.5:122b on a GH200 the past few days for rust/react/ts, and while it's clearly sub-Sonnet, with tight descriptions it can get small-medium tasks done OK - as well as Sonnet if the scope is small.

      The main quirk I've found is that it has a tendency to decide halfway through following my detailed instructions that it would be "simpler" to just... not do what I asked, and I find it has stripped all the preliminary support infrastructure for the new feature out of the code.

        That's likely coming from the 3:1 ratio of linear to quadratic attention usage. The latest DeepSeek also suffers from it which the original R1 never exhibited.

      • sheepscreek 3 hours ago

        That sounds awfully similar to what Opus 4.6 does on my tasks sometimes.

        > Blah blah blah (second guesses its own reasoning half a dozen times then goes). Actually, it would be a simpler to just ...

        Specifically on Antigravity, I've noticed it doing that trying to "save time" to stay within some artificial deadline.

        It might have something to do with the system messages and the reinforcement/realignment messages that are interwoven into the context (but never displayed to end-users) to keep the agents on task.

        • wood_spirit 3 hours ago

          Yeah that happened to me with Claude code opus 4.6 1M for the first time today. I had to check the model hadn’t changed. It was weird. I was imagining that maybe anthropic have a way of deciding how much resource a user actually gets and they had downgraded me suddenly or something.

          • e1g 2 hours ago

            Claude Code recently downgraded the default thinking level to ā€œmediumā€, so it’s worth checking your settings.

      • slices 19 minutes ago

        I've seen behavior like that when the model wasn't being served with sufficiently sized context window

        That sounds too close to what I feel on some days xD

      • reactordev 5 hours ago

        Turn down the temperature and you’ll see less ā€œsimplerā€ short cuts.

        • smokel 3 hours ago

          For the uninitiated: Interestingly, it is not advisable to take this to the extreme and set temperature to 0.

          That would seem logical, as the results are then completely deterministic, but it turns out that a suboptimal token may result in a better answer in the long run. Also, allowing for a little bit of noise gives the model room to talk itself out of a suboptimal path.

          • LoganDark 2 hours ago

            I like to think of this like tempering the output space. With a temperature of zero, there is only one possible output and it may be completely wrong. With even a low temperature, you drastically increase the chances that the output space contains a correct answer, through containing multiple responses rather than only one.

            I wonder if determinism will be less harmful to diffusion models because they perform multiple iterations over the response rather than having only a single shot at each position that lacks lookahead. I'm looking forward to finding out and have been playing with a diffusion model locally for a few days.

            • reactordev 2 hours ago

              Yup. I think of it as how off the rails do you want to explore?

              For creative things or exploratory reasoning, a temperature of 0.8 lends us to all sorts of excursions down the rabbit hole. However, when coding and needing something precise, a temperature of 0.2 is what I use. If I don’t like the output, I’ll rephrase or add context.

        This is my experience with the Qwen3-Next and Qwen3.5 models, too.

        I can prompt with strict instructions saying "** DO NOT..." and it follows them for a few iterations. Then it has a realization that it would be simpler to just do the thing I told it not to do, which leads it to the dead end I was trying to avoid.

    • Twirrim 6 hours ago

      I've been testing the same with some rust, and it's has spent a fair bit of time going through an infinite seeming loop before finally unjamming itself. It seems a little more likely to jam up than some other models I've experimented with.

      It's also driving itself crazy with deadpool & deadpool-r2d2 that it chose during planning phase.

      That said, it does seem to be doing a very good job in general, the code it has created is mostly sane other than this fuss over the database layer, which I suspect I'll have to intervene on. It's certainly doing a better job than other models I'm able to self-host so far.

      • Aurornis 5 hours ago

        > it's has spent a fair bit of time going through an infinite seeming loop before finally unjamming itself.

        I think this is part of the model’s success. It’s cheap enough that we’re all willing to let it run for extremely long times. It takes advantage of that by being tenacious. In my experience it will just keep trying things relentlessly until eventually something works.

        The downside is that it’s more likely to arrive at a solution that solves the problem I asked but does it in a terribly hacky way. It reminds me of some of the junior devs I’ve worked with who trial and error their way into tests passing.

        I frequently have to reset it and start it over with extra guidance. It’s not going to be touching any of my serious projects for these reasons but it’s fun to play with on the side.

      • sosodev 6 hours ago

        Some of the early quants had issues with tool calling and looping. So you might want to check that you're running the latest version / recommended settings.

      • misnome 4 hours ago

        > and it's has spent a fair bit of time going through an infinite seeming loop before finally unjamming itself

        I can live with this on my own hardware. Where Opus4.6 has developed this tendency to where it will happily chew through the entire 5-hour allowance on the first instruction going in endless circles. I’ve stopped using it for anything except the extreme planning now.

      • cbm-vic-20 3 hours ago

        I don't know much about how these models are trained, but is this behavior intentional (ie, the people pulling the levers knew that this is how it would end up), or is it emergent (ie, pulling the levers to see what happens)?

    • anana_ 3 hours ago

      I've had even better results using the dense 27B model -- less looping and churning on problems

    • abhikul0 5 hours ago

      Are you running it locally with llama.cpp? If so, is it working without any tweaking of the chat template? The tool calls fail for me when using the default chat template, however it seems to work a whole lot better with this: https://huggingface.co/Qwen/Qwen3.5-35B-A3B/discussions/9#69...

        • abhikul0 4 hours ago

          Yes, it fails too. I’m using the unsloth q4_km quant. Similarly fails with devstral2 small too, fixed that by using a similar template i found for it. Maybe it’s the quants that are broken, need to redownload I guess.

      What hardware do you have it running on? Do you feel you could replace the frontier models with it for everyday coding? Would/will you?

      • sosodev 2 hours ago

        Around 20ish tokens a second with 6-bit quant at very long context lengths on my AMD AI Max 395+

        I’m trying to use local models whenever possible. Still need to lean on the frontier models sometimes.

      • politelemon 4 hours ago

        60 to 70 on a 5080, but only tinkering for now. The smaller models seem exceptionally good for what they are, and some can even do OCR reliably.

      • bigyabai 5 hours ago

        I'm getting ~30 tok/s on the A3B model with my 3070 Ti and 32k context.

        > Do you feel you could replace the frontier models with it for everyday coding? Would/will you?

        Probably not yet, but it's really good at composing shell commands. For scripting or one-liner generation, the A3B is really good. The web development skills are markedly better than Qwen's prior models in this parameter range, too.

    • paoliniluis 6 hours ago

      what's your take between Qwen3.5-35B-A3B and Qwen3-Coder-Next?

      • sosodev 6 hours ago

        In my experience Qwen3.5 is better even at smaller distillations. From what I understand the Qwen3-next series of models was just a test/preview of the architectural changes underpinning Qwen3.5. So Qwen3.5 is a more complete and well trained version of those models.

      • kamranjon 6 hours ago

        In my experience qwen 3 coder next is better. I ran quite a few tests yesterday and it was much better at utilizing tool calls properly and understanding complex code. For its size though 3.5 35B was very impressive. coder next is an 80b model so i think its just a size thing - also for whatever reason coder next is faster on my machine. Only model that is competitive in speed is GLM 4.7 flash

        • xrd 6 hours ago

          What do you use as the orchestrator? By this I mean opencode, or the like. Is that the right term?

          • nvader 2 hours ago

            Another vote in favour of "harness".

            I'm aligning on Agent for the combination of harness + model + context history (so after you fork an agent you now have two distinct agents)

            And orchestrator means the system to run multiple agents together.

          • simonw 6 hours ago

            I use the term "harness" for those - or just "coding agent". I think orchestrator is more appropriate for systems that try to coordinate multiple agents running at the same time.

            This terminology is still very much undefined though, so my version may not be the winning definition.

          • kamranjon 4 hours ago

            I'm basically using the agentic features of the Zed editor: https://zed.dev/agentic

            It's really easy to setup with any OpenAI compatible API and I self host Qwen Coder 3 Next on my personal MBP using LM Studio and just dial in from my work laptop with Zed and tailscale so i can connect from wherever i might be. It's able to do all sorts of things like run linting checks and tests and look for issues and refactor code and create files and things like this. I'm definitely still learning, but it's a pretty exciting jump from just talking to a chat bot and copying and pasting things manually.

        We don't have a Qwen3.5-Coder to compare with, but there is a chart comparing Qwen3.5 to Qwen3 including Qwen3-Next[0].

    • a3b_unknown 6 hours ago

      What is the meaning of 'A3B'?

      • simonw 6 hours ago

        It's the number of active parameters for a Mixture of Experts (misleading name IMO) model.

        Qwen3.5-35B-A3B means that the model itself consists of 35 billion floating point numbers - very roughly 35GB of data - which are all loaded into memory at once.

        But... on any given pass through the model weights only 3 billion of those parameters are "active" aka have matrix arithmetic applied against them.

        This speeds up inference considerably because the computer has to do less operations for each token that is processed. It still needs the full amount of memory though as the 3B active it uses are likely different on every iteration.

        • zozbot234 3 hours ago

          It will benefit from a full amount of memory for sure, but AIUI if you use system memory and mmap for your experts you can execute the model with only enough memory for the active parameters, it's just unbearably slow since it has to swap in new experts for every token. So the more memory you have in excess to that, the more inactive but often-used experts can be kept in RAM for better performance.

          • EnPissant 10 minutes ago

            The ability to stream weights from disk has nothing to do with MoE or not. You can always do this. It will be unusable either way.

  • hintymad 5 hours ago

    There has been tension between Qwen's research team and Alibaba's product team, say the Qwen App. And recently, Alibaba tried to impose DAU as a KPI. It's understandable that a company like Alibaba would force a change of product strategy for any number of reasons. What puzzled me is why they would push out the key members of their research team. Didn't the industry have a shortage of model researchers and builders?

    • cmrdporcupine 4 hours ago

      Perhaps they wanted future Qwen models to be closed and proprietary, and the authors couldn't abide by that.

    • gaoshan 5 hours ago

      ICE has been detaining Chinese people in my area (and going door to door in at least one neighborhood where a lot of Chinese and Indians live). I was hearing about this just last week as word spread amongst the Chinese community here (Ohio) to make sure you have some legal documentation beyond just your driver's license on you at all times for protection. People will hear about this through the grapevine and it has a massive (and rightly so) chilling effect. US labs can try but with US government behaving like it is I don't think they will have much luck.

      *edit: not that it matters, but since MAGA can't help but assume, these are all US citizens and green card holders that I am referring to.

        • Jcampuzano2 4 hours ago

          The reality is - it doesn't matter. The fact that they have had as many false positives as they have and the way they treat people in general causes it to have rippling effects even for people who are legally here, or are considering legally immigrating.

          The risk and level of publicity is just too high for many people to even consider, especially people already intelligent/capable enough to immigrate anywhere else that doesn't have these issues or stay in their own country.

          • 0x3f 2 hours ago

            Have they had a lot of false positives? Almost every story I see seems to fall apart on further investigation. To be clear, I'm sure they have some false positives, but do they have a lot of them relative to any other immigration system?

            • Terr_ 2 hours ago

              Depends, how are we defining "false positive"? Ex:

              1. Detained the incorrect person

              2. Detained the correct person, with the correct legal status

              3. Detained the correct person, with the correct legal status, but in unlawful circumstances

              4. Detained the correct person, with the correct legal status, in ostensibly-lawful circumstances, but in a way which is unconstitutional or crazy

              An example of the final category are the immigrants that spent years being vetted, following the law, and doing expensive paperwork to be citizens. ICE snatched them when they showed up on at the last second as they were to take their citizenship oath. [0] Not because of anything they did, but because today's Republican party has decided that it's OK to hurt people based on their "shithole" country of birth.

              • 0x3f an hour ago

                These are all forms of false positives but the most popular news stories seem to be where they detain the correct person, correct legal status, lawfully, and the story happens to gloss over the facts about the legal status and focuses on the hardship. Yeah, it's a hardship to be split from your family, I can't deny that. But I'm not aware that most countries are very sympathetic to illegal immigrants.

                If anything I find the stories featuring white/European people oddly racist because they seem to assume that I, the reader, will assume a white/European person couldn't possibly be in violation of immigration rules. But all the ones I've read turned out that they were indeed in violation of immigration rules.

                Overall as a potential immigrant to the US myself, I find the process capricious and that US citizens by birth don't fully appreciate how painful it is or why it shouldn't be that way. But I don't find it notably worse or more onerous than the vast majority of immigration policies of other countries in practice.

          • 4RealFreedom 2 hours ago

            "especially people already intelligent/capable enough to immigrate anywhere else that doesn't have these issues or stay in their own country" Isn't that the point? Come here legally or don't come at all.

          No, all of the specific cases I heard about were Chinese people that were naturalized citizens (some for decades) who were cuffed and detained for a few hours before being released. As others have said it doesn't really matter, though. It's the sentiment that counts.

          Even if you're not likely to be deported from a foreign country, you wouldn't want to face frequent gang intimidation tactics, would you? Simply feeling threatened isn't fun, even if nothing truly terrible will happen to you (not to speak of the real risk in being detained regardless).

      They already kind of do, but I think anyone who was into US money has already left for it, and the money China is throwing at the problem is pretty good also. You can also have a lot more influence in a Chinese company without having to adopt a weird new American corporate culture.

          Anthropic has gone out of their way to make a point about how much they love and admire the US state and its defense sector. Only drawing the line at a very far point and even when they drew the line it was with a big thing about how they believe in the American defense sector blah blah blah.

          In any case, there's no way Anthropic's investors in Silicon Valley would countenance such a move.

          Also, I'm biased the logical place is Canada, not Europe. Much of the fundamental/foundational research on LLMs, and a large part of the talent, came from universities in Canada anyways.

            This US administration (or any admin) would almost certainly impose export controls on US AI technology before it would allow one of the frontier model providers to be acquired/relocate outside the US. It did the same thing when ASML wanted to acquire Cymer (California company that provides the EUV light source technology). The acquisition was only allowed under strict technology sharing/export agreements with the Dutch government.

            I'm not sure goals are totally aligned though. The current models are created by enormous expense. We know that many stages are done incorrectly. I am confident that they can be replicated without any unique US knowledge.

            At the moment my impression is instead that the issue is computational resources. It's important to stay near the frontier though, and to build up ones capacity to train large models.

            Consequently I don't think we need Anthropic. It wouldn't be terrible if they came. Especially if they picked a nice location. Barcelona would be very nice, for example.

      Well, the problem aren't just the NSF funding cuts. Everyone else is already dumping truckloads of cash. There's also the public health situation (who wants measles or polio?), the risk of retaliatory attacks from the countries we're at war with, etc. You could write paragraphs about why the US is less attractive to researchers.

      When I was a deep learning PhD in the first Trump administration, US universities were already very deeply affected by the Muslim ban, and so a lot of talent ended up in other countries.

      Sibling commentators are rightfully pointing out that foreigners, especially those who would not be recognized as white, face an onerous and risky customs process with long-term and increasing risks of deportation. When you see a headline like the NIST labs abruptly restricting foreign scientists, _everything_ else feels uncertain. Even if someone doesn't believe they're personally at risk for deportation, they're still seeing everything else.

      And then it all boils down to a reputational thing. The era where we were the top choice for research is in the past. If you start a PhD in the US on your resume during this era, you might be anticipating how you'll answe the question of why you weren't good enough to get accepted somewhere better.

    • ecshafer 6 hours ago

      China is also giving them dump trucks full of cash though. Plus you have to content with the nationalism reason (unfortunately this has died off in America for too many). The idea of building your country is valued for most Chinese I have met. Plus China is incredibly nice to live in, especially if you have lots of money and/or connections. So you can work in China, get paid lots of money, feel like you are doing good. Or In America you can get paid lots of money, and get yelled at by people online because the Government wants to use your model.

                  Does that matter? In China people don't judge the state of their civilization by how easily you can insult the police but whether you need to be afraid to meet them on the street. "I can insult my pedophile president" (who doesn't care if you do) isn't exactly a flex.

                  It does tell us something though that the evaluation of American life now consists of parasocial interactions with the president on social media. I'm starting to belief Bruno Maçães, ex Portuguese secretary of state, was prescient with his diagnosis that American material society has rotted to the point where life is now entirely defined by virtual interactions. That's the difference between China and the US today.

                  The president's a pedophile, a criminal, undeterred by democracy, economy or social disorder but you can freely yell into the void. Have you considered that in the US one can freely say all these things precisely because that's irrelevant?

                    Americans will vote for their Congress representatives in November. They will have a chance to decide how they want their government to be run.

            Sure, but the difference is that while the Chinese state is measurably awful on all sorts of human rights things within their own borders... they're not currently dropping bombs on foreign cities, starving a neighbour of critical petroleum shipments, or heavily funding an ally to slowly exterminate a population.

                My point is as a non-American I feel no allegiance to either state, and current events don't make me sympathetic to the geo-political aims of the USA. So I don't see a strong moral case for this tech being an especial purvey of either party.

                If you'd asked me two years ago my answer might have been different.

                And to the original point, yeah, I would feel entirely justified in the critique of engineers in providing tools to the US defense apparatus at this point.

            Have you experienced racism? In Japan atleast, it was evenly applied. That company won't rent to foreigners but this one will. That company won't hire foreigners but this one will. Police will bother you if you ride a bike, but they will be polite while they waste 10 minutes of your time asking for your gaijin card for biking while foreign.

            In the US people try to hide it and are far more sinister about it, since there are a lot of laws against obvious racism. The cops are also happy in the US to just kill you.

            The racism in the US comes out of hate where as what I experienced abroad was more, we don't think you'll fit in and follow the rules and you have to constantly prove that you can.

            I didn't spend too much time in China so maybe it is a racist hell hole.

            But my experience in Japan was that white immigrants were way more inclined to make a huge deal about the lighter racism they experienced because they had never been somewhere where their skin color was a disadvantage.

      I've noticed that open weight models tend to hesitate to use tools or commands unless they appeared often in the training or you tell them very explicitly to do so in your AGENTS.md or prompt.

      They also struggle at translating very broad requirements to a set of steps that I find acceptable. Planning helps a lot.

      Regarding the harness, I have no idea how much they differ but I seem to have more luck with https://pi.dev than OpenCode. I think the minimalism of Pi meshes better with the limited capabilities of open models.

      • malwrar 4 hours ago

        +1 to this, anecdotally I’ve found in my own evaluations that if your system prompt doesn’t explicitly declare how to invoke a tool and e.g. describe what each tool does, most models I’ve tried fail to call tools or will try to call them but not necessarily use the right format. With the right prompt meanwhile, even weak models shoot up in eval accuracy.

      Have frontier lab do the plan which is the most time consuming part anyways and then local llm do the implementation. Frontier model can orchestrate your tickets, write a plan for them and dispatch local llm agents to implement at about 180 tokens/s, vllm can probably ,manage something like 25 concurrent sessions on RTX 6000 Do it all in a worktrees and then have frontier model do the review and merge. I am just a retired hobbyist but that's my approach, I run everything through gitea issues, each issue gets launched by orchestrator in a new tmux window and two main agents (implementer and reviewer get their own panes so I can see what's going on). I think claude code now has this aspect also somewhat streamlined but I have seen no need to change up my approach yet since I am just a retired hobbyist tinkering on my personal projects. Also right now I just use claude code subagents but have been thinking of trying to replace them with some of these Qwen 3.5 models because they do seem cpable and I have the hardware to run them.

Tool calling with opencode worked without issues, but general coding ability is still far from sonnet-tier. Asked it to add a feature to an existing react app, it couldn't produce an error-free build and fell into a delete-redo loop. Even when I fixed the errors, the UI looked really bad. A more explicit prompt probably would have helped. Opus one-shotted it, same prompt, the component looked exactly as expected.

          But I'll be running this locally for note summarization, code review, and OCR. Very coherent for its size.

      What Anthropic was complaining about is training on mass-elicited chat logs. It is very much a ToS violation (you aren't allowed to exploit the service for the purpose of building a competitor) so the complaint is well-founded but (1) it's not "distillation" properly understood; it can only feasibly extract the same kind of narrow knowledge you'd read out from chat logs, perhaps including primitive "let's think step by step" output (which are not true fine-tuned reasoning tokens); because you have no access to the actual weights; and (2) it's something Western AI firms are very much believed to do to one another and to Chinese models all the time anyway. Hence the brouhaha about Western models claiming to be DeepSeek when they answer in Chinese.

      • red2awn 3 hours ago

          So they're paying expensive input tokens to extract at best a tiny amount of information ("judgment") per request? That's even less like "distillation" than the other claim of them trying to figure out reasoning by asking the model to think step by step.

          • red2awn 2 minutes ago

            LLM-as-a-judge is quite effective method to RL a model, similar to RLHF but more objective and scalable. But yes, anthropic is making it more serious than it is.
