    "the gains showed up when tokens stopped being rationed" - I can totally see that. I am leading (as an external consultant) a larger dev team for a huge insurance company. The devs are quite junior or in general more the "I became a sw-eng here because that company is the only big employer in a 1h radius" type of people (meaning: No rockstar developers). Most of them do not play with AI in their spare time, and they have been told to spend claude tokens wisely. Everybody is too afraid now to play with it and explore during work hours for fear of being token shamed.

    At the same time, most of their junior devwork can be replaced completely by AI - so they really should start to learn how to work with it. I recommended everybody to get a private 20€/month claude subscription and use it for toy projects. I have younger devs (early 20s) in the team that told me they won't spend private money, or simply have no usecase in their private life for AI. We talk about software engineers here, and IMHO most of them are in denial of the fact that their skills have mostly become worthless if they don't start to pivot to something valueable.

      If you were to take away my work's $500 budget for Opus 5.5 and replace it with unlimited use of GLM-5.3, it would be a huge downgrade in my opinion.

      If your employer is so cheap as to spend a $100 or less per month per engineer, while being large enough not to have access to the subscription plans, a move to self hosted or cheap providers does make sense in my view.

        I am perfectly able to do the tasks with own custom harness and unlimited local Qwen 3.8 27B with 150t/s. Harness needs search capability and more fine-tuning for the job.

        You need less words to describe the intent with Astra/Opus 5.5, and it automatically usually observes the best practice that you don't need to explicitly tell, but with only a slight more effort you can get the job done. I have even made security audits with Qwen 3.8 27B against projects fully written with Claude Opus and it is a bit mind-boggling, but there have been tens of vulnerabilities, identified by this model alone. This excludes the issues found when guiding more myself.

      • littlecranky67 1 hour ago
        The thing is the have been told to use the tokens wisely, but no limit is communicated. Still everybody is hesitant. To be fair, the company runs claude on AWS bedrock for data privacy requirements at a different pricelevel. But I guess that is the drawback for german job-security: each and all of them know they basically can't get laid off.

        I also attribute a lot of it to be just plain outright denial. I have a feeling a lot of people don't WANT to understand that their coding skills they acquired over years have dropped a lot in worth. It is the "as long as I don't step on a scale, I can't be overweight" kind of denial. You are afraid to see what is behind the curtain, so you simply don't do it.

          What exactly is the skill you acquire by using more AI? If the models get smarter, isnt it a waste of time to get good at the current gen?
          • kragen 10 minutes ago
            I'm probably a worse programmer than I was before I started using frontier AI models, in the sense that I probably have a harder time reading, writing, and debugging code. And I doubt that my knowledge of the AI models themselves will have lasting practical value. But, because of the explorations I've done with them, I know substantially more about input method APIs, UEFI, PCIDs, seL4, WebAssembly, GLSL, Service Workers, CORS, server-sent events, CSS, content-security policies, memory-hard PBKDFs, Android, numerical integration, Verilog, V8 security, Linux process namespaces, hypervisors with VT-x, multitouch user interface design, radio communications theory, power electronics, physical-layer communications protocols, NTSC video signals, TLA+, bounded model checking, generative testing, theorem provers, FPGAs, Linux system call overhead, Unix mailbox formats, physical modeling synthesis, damped resonance, KaTeX, geology, dishwashing detergent, microbiology, Cyclone, thermodynamics, X-Windows, localStorage, AVX, Excel, and IndexedDB, for example. Most of these are things I knew very little about before, so I may not know much about then now, but it's enormously more than I did.

            Aside from being very pleasurable, I have the impression that this knowledge is valuable in designing systems whose implementation I can then elicit from an AI model. I don't know how long that knowledge will remain instrumentally valuable.

          • littlecranky67 18 minutes ago
            The skill of getting familiar with AI use, how to use it, when to use, learning when NOT to use it, is the skill that will land you your next job. Or would you in 2030 expect to hire software devs that never touched AI?

            You get better at building things - asking the right questions at the right time, knowing what to trust and what to look into.

            Not very different from managing a team, just without the human problems.

          Help me understand what exactly is the drawback you’re mentioning. In your previous comment you were suggesting these people spend their own personal money and personal time on projects to benefit their work time. They (quite reasonably, it seems from the limited context) decided that no, they won’t dedicate life and resources from outside work to more work. Fortunately, it seems they have some job security (German, but probably some from the EU as well) which allows them to make whatever choice they believe is healthier to them, without fearing repercussions. What’s the drawback?

          • littlecranky67 45 minutes ago
            No you misunderstood my comment. I suggested they spent their private money - 20€ a month for the lowest Max flatrate tier - because to me it is obvious that you absolutely need to develop the skill to work with AI. They only have the "pay-per-token" model on their work accounts and laptops, because that is what large corporations get - no flatrate. That leads them to not work with AI. Most of them just refuse to get that 20€/month subscription to experiment with it on their private laptops. I didn't say private time - company policy is no US cloud services for work related topics so they would have to install it on their private computers. They totally could work on toy projects during their time, as the team is in homeoffice a couple a days per week.

            I mean the drawback is none as long as they have job security. Unless you realize you work for a public entity that is paid for by the tax payer.

            • latexr 30 minutes ago
              Thank you for attempting to clarify, but it doesn’t seem to me like I misunderstood the first time. Seems you are indeed suggesting they spend their own personal money and hardware for a skill to be used on work time, and that they use their work time for personal projects to ultimately benefit that work time. It seems reasonable to me, and societally positive, that people have the freedom to choose to not do that.

              I don’t see how working for a public entity is relevant. If anything, I sure hope (but I’m not deluding myself) the people who work for public entities work slowly, deliberately, and methodically. The last thing I want from public entities is a focus on “velocity” and merging code the authors don’t understand.

              • littlecranky67 19 minutes ago
                > and that they use their work time for personal projects to ultimately benefit that work time.

                That is exactly what I am saying and I would advise them. If you are early 20s right now and a software dev, just waiting for your employer (a large, slow enterprise) to train you an AI seems like a career killer. The whole attitude of "I landed a job with job security, so I am not doing a thing more than I have to" is what drives germany into the ground...

                  That seems strange to me. A country is made of people, and people are more than their jobs. The fixation on work above everything to benefit an entity whose only purpose is to make money and that would chew and spit you out at the first opportunity seems unhealthy to me. I’d much rather we worked on making the people happy and not concentrate so much wealth in the hands of a few, that seems to me like a better way to improve a country. But hey, happy to disagree. Thank you for engaging and expressing and clarifying your views.

                I used an immense amount of personal time and money to make me a better employee, it was called getting a degree from a university.

                I still sometimes spend a bit of personal money and time to tinker with technology, sometimes on the basis that it'll probably be good to know some of this stuff. It's like being surprised a chef likes to experiment a bit in their kitchen at home.

                Their point is with total job security there's no real drive to actually be good at your job and little incentive to improve. Just be good enough to not be labeled entirely incompetent and truly unfit for the job, not any better. Would you go to a doctor who hasn't bothered learning anything new about medicine for decades and still practices like it's the 1950s, or one which continually evolved their practice to stick with modern times?

      > ... and IMHO most of them are in denial of the fact that their skills have mostly become worthless if they don't start to pivot to something valueable.

      But your comment says it several time: the valuable skill is being already a seasoned dev.

      Then AI is superpower.

      It's for the junior that things sucks big times.

      I see it all around me: senior devs are empowered while juniors are not even hired anymore.

      • littlecranky67 11 minutes ago
        It is a shock going through the industry, and we are just starting. I think future software engineers will need more training years and more unpaid time getting skilled. More like surgeons, who need almost 10 years of training until we actually let them operate on live patients.

        Given that we are seeing a big retirement wave of the boomers, a lot of seasoned devs will retire in the next 10 years. So there should be enough demand, and a big enough paycheck for that decade long training to make its moneys worth.

    • customguy 37 minutes ago
      Are you not worried about this being a sort of one-way street? Do you have any strategies to avoid ending up with a codebase you cannot work on without "AI"? when I think insurance company, I would assume the value seems to be more in the trust you build up over decades of with customers, not producing lots of code faster.
      • littlecranky67 25 minutes ago
        Well I am still in the loop as a senior dev and I get to review everyones code before it gets merged. Official guidelines is that everybody is responsible for the code they produce (with or without AI) and must understand it when they give it to the reviewer. I've been doiing this 3+ years at this company, so before the whole AI thing landed. I am explicitly not allowed to implement features myself (because the idea is the juniors learn and get trained).

        Now, within the last 6-12 months of AI advancement, I think you could lay off half or even 3/4 of the team if I was explicitly allowed to implement features myself using AI. But that is not the current policy.

        As for worries "ending up on a codebase you can't manage without AI" - my personal take is: No, I am not worried. Because going forward AI will always be available in the development workflow. That is my own opinion, not the corporation standpoint, however.

  • jacquesm 1 hour ago
    We did the same thing, on much less powerful hardware but it has served us very well and we don't need to worry at all about the question whether or not the suppliers of inference services can be trusted long term with our data. The answer to that question in my opinion is 'absolutely not'.

        By pulling the plug. This box simply has no pathway to the internet. I do pretend I have one and it's interesting to see what it tries to do. For instance, Qwen tends to try to hit ali related URLs for websearch and is very disappointed when the mothership is not responding. I've yet to catch a model on an exfiltration attempt, either they are so good at this that it escapes my scrutiny (possible but unlikely) or they are simply not doing it. I would bet on the last one. Just don't say you're working for the Tibet Liberation Frontier or the Keep Taiwan Independent movement.

        Your inference server is just an inference server that spits out tokens. You can use the same harness, etc. you’re basically just changing the API base URL.

    What does "blended $0.30 per 1M tokens" mean - is that input or output or average across the two? (asking as am trying to benchmark that cost against public GLM providers on Openrouter)
  • redmalang 1 hour ago
    For the past several months about 90% of the work we do goes to open source models. If you ignore the noise around 'cheap' etc, you might find that with a little extra effort to more precisely define what you need not only do these models generally work as well, and they will generally more closely follow instructions - on longer timeframes this is actually pretty helpful.

    They are less good on ambiguous prompts like 'fix all the problems' (which to my chagrin is a very common prompt it turns out..)

    • jacquesm 1 hour ago
      Yes, that's a good point: you really need to work on the prompts, even if the harness is the same. Ambiguity is a real problem as is what we call 'the negative space', what isn't in the prompt but what is implied by the prompt to be undesirable. You need to spell that out in more detail it is not enough just to say 'do x' but you also need to make sure to say 'and not y or z', and knowing what y or z are requires a bit more insight into what hobby horses are encoded in a model.

      To give one example: I'm doing a lot of stuff that involves hardware. When settings things up for fixing a bug I have to make sure to include that the hardware has been tested and works well. If I don't do that the model will almost certainly spend a ridiculous amount of time speculating about all the different ways in which the hardware could be broken (including theorizing about chip mask errors and all kinds of other obscure and rarely seen in practice defects). It's going to end up telling itself that for sure the 500 lines it just produced are absolutely perfect and the device that is on the i2c bus is broken in a way that it just really can't progress with solving the issue because there is nothing wrong with the code.

      These kinds of blind-spots are funny when they happen once in a month but when they happen regularly it begins to be irritating. Adding a line or two to the prompt will take care of the issue. Frontier models tend to be better at this sort of thing.

      • redmalang 48 minutes ago
        Us too! Hardware is very interesting - I find in fact that 'smart' (aka expensive) models can overthink complex hardware state machines and end up doing atrocious code because it will try to handle every possible edge case (unbidden, mind you). What has worked very well is harvesting and aggregating lessons and feeding this automatically into our pi sessions, this allows the models which listen to instructions to avoid a lot of time burning tokens on internal dialogue to ascertain the nature of reality.. but the expensive ones: a) they dont listen b) they ironically know too much!
        • jacquesm 43 minutes ago
          Funny, I wonder how many people are retracing the same pathways. Another interesting one: asking for reboots or resets to start from a 'known state' even though this will not change a thing. But it's a quick path out of the trouble spot that might just work so why not try it. I've added the following line: "The hardware is on a spaceship and is impossible to access by an operator and for some reason they forgot to include reset logic, so we have to work with what we've got.". I've been gaslit by AI so often I figure I can return the favor without penalty.
          • redmalang 35 minutes ago
            IDK why/how this works but by giving it a standardised set of apis to interface with the hardware (read logs, restart it and so on) we find models tend to behave much better ... it wont randomly do stuff it feels is appropriate for a debugging session.

            At this point though our context is so dynamic because of lesson propogation its hard to think about a model on its own - a vanilla harness (which we were forced to use recently because the memories system went down for a bit) just felt so different!

            • jacquesm 31 minutes ago
              I have the agent software set up to log every byte in and out of the model into a file, time stamped and which side of the conversation was active as well as all of the tool calls, parameters and stdin/out of the tools. Every week or so I start a job to process that log file and to extract useful lessons for future sessions. These go into a LESSONS.md file that gets read by every agent session on start-up.

    This is a sane version of what “sovereign” AI can look like for many. In Canada we’ve just had this national plan to overpay for an inferior AI product in the name of sovereignty. Even if GLM is slightly behind, this is likely close to the Pareto frontier.

    They also could consider putting this on openrouter when they have spare capacity to make the most effective use of the hardware.

    > Per David Abitbol, who leads AI ops there: 56 Nvidia B200s, a blended 30 cents per million tokens, roughly a tenth of what they paid Anthropic and OpenAI.

    So they've invested around $2.5M-3M into hardware + monthly operating costs (electricity, updates, cooling). I wonder how much did they spend on tokens to decide to make such a switch. I mean if they used to spend $500k-1M per month just on tokens then it would pay off in a year or so, assuming their infra will be stable and efficient.

    We'll see if that's a trend for mid-big companies or just an experiment.

    All that math is assuming that it's all self-hosted in their data center or so and not paying to a cloud provider, which will be probably more expensive.

    • InsidiousWombat 1 hour ago
      I doubt local will be all that common aside from regulatory requirements but buying them off your cloud provider will be the new norm for many enterprises.

      Are you assuming that they bought the hardware? because they could also be renting the metal off a provider, in which case they either pay by the hour or have a yearly commitment to save on costs.

      The B200 was launched in 2024 if I'm not mistaken. The big gamble with this might be how fast these will deprecate in value/use as soon as Nvidia launches a new and better product.

      At the moment at least Nvidia doesn't have a incentive to release a new product because it's sold out as it is and probably doesn't want to plunge their customers in depth with outdated products?

      Personally, I think Anthropic and OpenAI will introduce enterprise plans such as $2,000/month/engineer plans that will give 100x more tokens than the current max plans and then charge API pricing.

      Yes, margins will go down a bit but the frontier labs still have some leverage.

    At dayjob we're also using self-hosted GLM-5.3 via our flavour of pi.dev but teams still have discretionary power over using Claude Code or not (there's a team's budget to spend on whatever the team decides). Some teams like mine still like to use Claude Code for a lot of the work but most stuff doesn't require the latest and greatest LLM and can be done with "lesser" LLMS by simply throwing a lot of tokens and compute to it.

        MoE models can be largely offloaded to system RAM - recent versions of llama.cpp automatically distribute parts of the model, with all the dense parts going into VRAM and just the routed experts residing in system RAM.

        It's an idiot (no Thinking), so it has to go over its work several times to get it right, but it's the largest idiot I can feasibly run at the moment.

        Also by accident I'm undercutting the only provider of this model on OpenRouter by 40%, doing $0.48/mTok.

    This is the right call - there's little proof that the quality gap between open models and OAI/Anthropic stuff translates to business results, but you surrender all control of your data to a third party.

    The last cause might be a straight up blocker - certain financial regulations straight up prevent you from giving third parties to your data (esp outside national/EU jurisdiction), no matter what documents you sign.

    It's probably true that open weight models are "good enough" for most software engineering tasks.

    But the goal posts will move and I think frontier labs will find new areas that have a need for absolute frontier.

    • cassianoleal 1 hour ago
      "Frontier labs" makes it sound like there's some special sauce to these companies. There isn't, other than very smart people working on problems.

      Guess who else has that? The Chinese companies developing open weight models. In fact, the vast majority of AI science comes from China. They might still be playing catch up in some areas, but they're also leading in others (famously DeepSeek's inference architecture as an example).

      There is IMO a non-trivial chance those labs will eventually surpass the US ones and become themselves "frontier", and that may happen sooner than a lot of people expect.

      Of course, it still remains to be seen if they will keep publishing the weights at that point.

      • aurareturn 1 hour ago
        Chinese labs are gated by lack of compute, at least until they can build their own EUV machines.

        Opening the weights isn't just a technical thing, it's a geopolitical decision which likely in part comes from the top of the CCCP (by either request or just implicitly allowing it).

      And they will keep it to themselves to extract the value for as long as possible.

      On both frontiers and open. And lately the gap has been closing so if anything yeeting Anthropic etc is getting more viable over time

    This is probably only relevant if you go over the 150 engineers putting you in the enterprise bucket and forcing you to pay by the token rather than the subsidized Claude code plans. If you need 150 engineers all with frontier model accounts maybe you are doing something wrong ;)

      If you want zero data retention you have to go api only.

        Time for the daily reminder that ZDR is a pinky-promise.

        ZDR is a contract clause. That means:

            - It is subject to the rest of the contract, e.g. the good old "subject to lawful request or court order" carve-out clauses
            - It is subject to random provider exceptions, e.g. see Anthropic and Fable.
            - You have no way of verifying it beyond "trust me bro".
        
        Basically you the only options are:

             - Run your own hardware which is obviously the ideal situation
             - If you can't run your own hardware, use confidential computing which runs the AI in secure enclave, e.g. Privatemode[1] (Germany) or Tinfoil[2] (US)

          For my companies purposes US contract law is risk mitigating enough.

          Which is why everybody buys tokens from Amazon or Microsoft or Google, not anthropic or OpenAI.

          Because you already have your BI and mails on these providers.

        I feel ZDR is the same as the EU data privacy shield
