    That's because Claude is on a lunch break and decided to take a short breather.

    I think we all deserve a little break right now.
  4. 4. sebastiennight||context
    I'm experimenting with a simple ritual: if Claude is out, I'm out.

    I'll just go for a walk outside.

    And I don't mean "if I can't access Claude to do my work", I mean, just in general - I'll just ping claude.ai from time to time and use Claude's breaks as a break reminder.

    Why should AI get a breather and not us?

    I've been seeing much higher session limits late at night (US time). Workday usage struggles though.

    Can you speak a little more to this? I'm curious what kind of parameters one must consider/monitor and what kind of novel things could go wrong.
  34. 34. aleksiy123||context
    My guesses are:

    hardware capacity constraints is going to be the big one

    Effective caching is another, I bet if you start hitting cold caches the whole things going to degrade rapidly.

    The ground is probably shifting pretty rapidly.

    Power users are trying to get the most out of their subscriptions and so are hammering you as fast as they possibly can. See Ralph loops.

    Harnesses are evolving pretty rapidly, as well as new alternatives harnesses. Makes the load patterns less predictable, harder to cache.

    The demand is increasing both from more customers, but also from each user as they figure out more effective workflows.

    Users are pretty sensitive to model quality changes. You probably want smart routing, but users want the best model all the time.

    Models keep getting bigger and bigger.

    On top of that they are probably hiring more onboarding more, system complexity and codebase complexity is growing.

  35. 35. lostlogin||context
    But… imagine that same scientific research but you have an unlimited budget. I’d imagine that helps.

    Some of the comments here mention their monthly spend, and it’s eye watering.

  36. 36. rvnx||context
    I think you have to see this as a bunch of stateless requests, and this makes the problem way easier.

      LLM requests that do not call tools do not need anything external by definition.
      No central server, nothing, they can even survive without the context cache.
      All you need is to load (and only once!) the read-only immutable model weights from a S3-like source on startup.
    
      If it takes 4 servers to process a request, then you can group them 4 by 4, and then send a request to each group (sharding).
    
      Copy-paste the exact same-setup XXX times and there you have your highly-parallelizable service (until you run out of money).
    
    It's very doable, any serious SRE can find a way setup "larger than one card" models like Kimi or DeepSeek (unquantized) if they have a tightly-coupled HPC (or a pair of very very beefy servers).

    If you run out of servers, then again a money problem, but not an architectural problem (and modern datacenters are already scalable).

    Take the best SRE, but no budget, and there is no solution.

    So inference is the easy part.

    Codex or Claude Code if it takes lot of time or have slow cold latency, it's considered very acceptable.

    Some users would probably not even see the difference if a request takes 2 minutes versus 3 minutes.

    The real difficult part is to have context caching and external tools, because now you are depending on services that might be lagging.

      Executing code, browsing the web, all of that is tricky to scale because they are very unreliable (tends to timeout, requires large cache of web pages, circumventing captchas, etc).
    
    These are traditional scaling problems, but they are more difficult because all these pieces are fragile and queues can snowball easily.

    just tried it, can confirm claude.ai is down.

    So there was a recent article that I read which said that claude is now trading at a trillion dollars (yes with a T) evaluation in private markets.

    We are definitely creating corporations and people which depend on AI companies themselves and the reliability of these tools is certainly a question worth asking. I am seeing quite many downtimes in products like github and claude being shown on Hackernews multiple times.

    Is there a life cycle of enshittenification of such products which grow too valuable? What are (are there?) some practical lessons for such scalability that these trillion dollar companies are missing or is it just a dose of reality that such massive corporations can't compete with downtime with even my 7$/yr vps?

    My question is, Is this an engineering roadblock with its limits in reality for or a management/entreprise roadblock for low downtime?

  47. 47. plodman||context

  52. 52. KronisLV||context
    > There are a multitude of reasons that a system can go down.

    Start doing post mortems then!

    At the very least, them using any off the shelf service that's shitting the bed would inform others to stay away from it - like an IAM solution, or maybe a particular DB in a specific configuration backing whatever they've written, or a given architecture for a given scale.

    Right now it's completely like a black box that sometimes goes down and we don't get much information about why it's so much less stable than other options (hey, if they just came out and said "We're growing 10x faster than we anticipated and system X, Y and Z are not architected for that." that'd also be useful signal).

    Or, who knows, maybe it's just bad deploys - seems like it's back for me and claude.ai UI looks a bit different hmmm.

  53. 53. SpicyLemonZest||context
    I have no inside knowledge of Anthropic. But having done a lot of postmortems in general, one of the key dynamics that routinely comes up is "we know we keep shipping breakages, and we know these new procedures would prevent many of them, but then we wouldn't be able to deliver new stuff so quickly". Given where Anthropic is at and what they believe about the future of software development, that's a tradeoff that they may very well be intentionally not making.
  54. 54. MavisBacon||context
    Glad I started using the desktop app which is still working. Gotta say though, all of these difficulties with Claude are making me nervous as I use it a lot for work and really don't like ChatGPT/OpenAI for functional and personal reasons. Zo Computer has been my main fallback when Claude is failing, I'll use one of their many models temporarily within Zo's interface.

    Our expense is roughly around 12.3 software developers when you break it down across all people related expenses. But we've spent alot of time and energy prior to this focusing on our ability to measure our software development output across multiple teams. The delivery improvements are not evenly applied across all teams, but the increases that we have seen suggest a better ROI than if we had hired 12 developers.
  73. 73. protonbob||context
    I guess if you think about your teammates as purely inputs and outputs and not people that can improve and contribute in the workplace in other ways.
  74. 74. SimianSci||context
    Respectfully, After a certain level of compensation, you are indeed judged purely off of input and output. Workplace improvement does not justify your salary.

    You will also find that many problems in the harder sciences do not get easier by throwing more bodies at them. Comments like these remind me that some project managers think they'd be able to delivery a baby in 1 month if they simply had 9 women.

  75. 75. oarsinsync||context
    > Respectfully, After a certain level of compensation, you are indeed judged purely off of input and output. Workplace improvement does not justify your salary.

    I'd have to disagree. There's a narrow band in the middle where that's true, but once you exceed that, your personal inputs and outputs matter less and less, and the contributions you make to the overall workplace, and how well you enable those around you, make a larger part of why you're compensated.

    Even as an IC, the more you're able to mentor and elevate the people around you, the more your compensation will grow (if you're in the right place, and thus already at the right earnings bracket)

  85. 85. shimman||context
    GitHub, along with MSFT in general, have massive copilot mandates where workers are being shamed into using slop tools to fix serious on-going issues. GitHub seems wholly incapable of resolving their issues: money isn't a problem, talent isn't a problem, but business leadership is definitely a major problem.

    Look at how other companies are suffering massive outages due to LLMs too like AWS and Cloudflare. Two companies that use to be the best in the industry at uptime but have suddenly faltered quite quickly.

    Companies that have even worse standards will quickly realize how problematic these tools are. Hopefully before a recession because this industry seems to be allergic to profitable businesses and leaders that have been around since ZIRP have shown zero intelligence in navigating these times.

  86. 86. kentonv||context
    None of the three major Cloudflare outages in the past six months had anything to do with LLMs. They were regular old human mistakes.

    We did, however, determine that at least one of them (and perhaps all) would have been easily caught by AI code reviewers, had AI code reviewers been in use. So now we mandate that. And honestly, I love it, the AI reviewer spots all sorts of things that humans would probably miss.

    (We also fixed a number of problems around configuration that would roll out globally too fast, leaving no time to notice errors and stop a bad rollout, as well as cases where services being down actually made it hard to revert the change... should be in a much better place now. But again, none of that had to do with LLMs.)

    And yet they will continue to spend wheelbarrows full of money with Anthropic because they want so badly to reach the point where they can fire you.

  88. 88. SimianSci||context
    I think there is alot of baseless fury behind your words, but my regular interactions with my leadership dont lead me to think they have the end goal of replacing labor. We're blessed to have leadership with technical backgrounds, so the tools are regarded more as significant intelligence enhancers of already exceptionally smart engineers, rather than replacements.

    Doesnt seem to us to be wheelbarrows of money, when you consider the average AWS/Azure bill.

  89. 89. protonbob||context
    Not ever hiring juniors and eventually mids is just replacing labor with extra steps.

    I think the message you responded to already refuted your point of view.
  91. 91. SimianSci||context
    Throwing bodies at a problem doesn't always scale. There are many difficult problems that do not get easier by throwing more juniors or mid level engineers at them.
  92. 92. sillysaurusx||context
    Huh? Your other comment explicitly said you were replacing labor: https://news.ycombinator.com/item?id=47939146

    > the increases that we have seen suggest a better ROI than if we had hired 12 developers.

    You can’t argue “we were able to get away with not hiring more developers” and also say you aren’t replacing labor.

    Morally I trend towards your side of things, but it’s also important to be realistic about what you’re actually doing. Money is going towards Anthropic and not towards new hires. That’s a replacement of labor. It doesn’t matter what the end goal was.

  93. 93. therobots927||context
    “Baseless fury”

    I’m glad your leadership isn’t trying to fire everyone. But in case you live under a rock, tech layoffs are at all time highs. Companies are rewarded by the public markets for laying off workers.

    Simultaneously we have AI industry leaders warning of an employment apocalypse once AGI is achieved.

    And you think it’s baseless. Have some class bro.

    Run Facebook on a single Proxmox box and demand would still outstrip the supply.

    How do things like prompt caching etc play into that? Would I theoretically have a more stable harness backing my usage?

    Im seriously over the current claude experience. After seemingly fixing my 4.6 usage by disabling adaptive thinking and moving to max effort, it seems that the release of 4.7 has broken that workflow and Im 99% certain that disabling adaptive thinking does nothing even on 4.6 now. Just egregious errors in 2 days this week after coming back from vacation.

    If you don’t mind an opinionated harness that asks for a pretty specific workflow, but one that works well, use OpenCode.
