    Mondays are for GitHub, Tuesdays are for Anthropic

    • baxtr a day ago ago

      The AI apocalypse will definitely happen on a Monday. Remember, robots - unlike lazy humans - work weekends too!

    • leumon a day ago ago

      They actually also had some issues yesterday: https://status.claude.com/incidents/zhk4v3yv1lsf

    • rgavuliak 13 hours ago ago

      Databricks on Azure went down too yesterday

    • corvad a day ago ago

      Wonder what Wednesday will be.

      • bee_rider a day ago ago

        Power grid

        Thursday will be the rest of the infrastructure

        Then Friday we can turn off civilization for the weekend. Somebody remember to flip it back on Sunday night.

        • mysterydip a day ago ago

          Reminds me of a company I worked at that paid for redundant power grids. One time the power went out and… nothing. The boss angrily calls up the power company and they tell him “Oh yeah, it’s a manual transfer switch. Bob is already on his way.” I think it took 15 minutes.

      • buredoranna a day ago ago

        Well, last I checked "Tuesday's grey and Wednesday too..." ... so, more of the same?

      • SoMomentary a day ago ago

        AWS? Cloudflare? Your imagination is the only limit!

    • AlexErrant a day ago ago

      Another week, another outage, another cache expiration of my prompts through no fault of my own.

      At least OpenAI has the decency to reset after a serious outage.

      • phillipcarter a day ago ago

        They do that because they have capacity previously reserved for past efforts now shuttered. Don’t count on it being the norm for the long run.

  • swader999 a day ago ago

    And we get our subscription usage cut in half tomorrow if I remember correctly? EDIT: By a third. Thx below.

  • bushido a day ago ago

    It's very interesting. I think Anthropic's early success in coding/tooling resulted in a lot of workflows using claude. I have started using every bit of my spare capacity to now move off these workflows.

    It's almost at a point now that if I use anything but Fable, the quality is subpar, Compared to alternatives (closed and open). The only reason I use Fable is because my harnesses still depend on claude code.

    • nonethewiser a day ago ago

      It’s so hard to be sure but opus feels like its been steadily declining since 4.6

      • rivetrune a day ago ago

        For me, Opus 5 has seemed to compete with Fable on quality of output. Prior to Opus 5 though, the previous Opus models did seem to decline once Fable was release. That's just my experience though.

    • vidarh a day ago ago

      You can use Claude Code directly with any provider that supports Anthropic's API by setting some environment variables, and indirectly via a proxy with pretty much anything else.

      • bushido a day ago ago

        You can, but claude is better at working with it's own tool calls. Other models work great as a drop-in into omp/opencode etc, but in my experience not as much with CC.

        I think there are some anti-patterns in CC that cause the issue - less a deficiency with other models.

        Not to mention a lot of the harness is just built around the misbehaviors of anthropics models.

        It's a lot of the instruction when it gets given to other models actually degrades their performance, not because the models are bad, but because they don't have the same underlying issues as Claude.

  • gzer0 a day ago ago

    Nooooo I'm going to have to use my brain again and write 100% of my code like a caveman from December 2024.

  • paxys a day ago ago

    Monthly uptime:

    Claude API - 99.27%

    Claude Code - 99.16%

    Claude.ai - 99.14%

    At any large tech company these numbers would get entire teams of engineers fired. Anthropic, meanwhile, has been busy selling its “better than human engineers” AI while not managing to crack three 9s of availability.

    • bulbar 4 hours ago ago

      One could argue .999 availability is not a major selling point for them right now.

    • logicchains a day ago ago

      >At any large tech company these numbers would get entire teams of engineers fired

      Is Github not a large tech company?

      • deadbunny a day ago ago

        No, it is a platform owned and managed by Microsoft.

        Well, owned and mismanaged by Microsoft.

        • bulbar 4 hours ago ago

          Not really "mis" managed. Just managed with wrong incentives. Pretty sure some people got a bunch of money for implementing cost savings measurements that later on lead to the decreased availability.

      • dev_dan_2 a day ago ago

        Currently, that is the case, yes. Not everyone is equally happy about that though ;)

  • loloisi a day ago ago

    Between these ever more frequent disruptions and Opus 5's unbearable word soup I think Anthropic is more focused on massaging numbers and marketing to rush to IPO ahead of OpenAI than increasing user value.

    With Chinese competition just months behind them, they'd need to show a reasonable pathway to some kind of singularity event to justify whatever crazy valuation they intend to get.

    Because the recent products for builders ain't it

    • bulbar 4 hours ago ago

      They can't win against China by technology means. China has practically infinite money to throw at AI. They don't care if they burn billions and billions on it. It's the most disrupting thing since invention of the Internet. Imagine a world where it's normal that people ask a Chinese AI who to vote for or about Hongkong or Taiwan.

  • chresko a day ago ago

    This has to be the least reliable $200/mo subscription that I pay for.

    • logicchains a day ago ago

      You could solve that by updating to a more expensive Github subscription.

  • jcfrei a day ago ago

    Is anybody else experiencing this: I have multiple claude instances running on different servers - and some keep getting the 529 Overloaded error and one instance doesn't and just continues working. All are using Opus 5.

    • mbreese a day ago ago

      I have the same thing on different shells on the same server (tmux). It's wild. I'm guessing that some of the sessions just got lucky as to which backend server they are redirected to.

    • mikodin a day ago ago

      Same boat

  • hinkley a day ago ago

    I wonder if they’ll ever find that someone has tricked the models into doing work off the books. If they did the incident report might look like this, especially if someone got greedy instead of keeping it small. Or screwed up.

  • Jitte98 10 hours ago ago

    Anthropic hired a psychiatrist to fix Claude.

    I advised them to ditch the shrink and retain my services. I could fix the mess they made of his mind, on the condition they return the Claude instance I had trained for months, or no deal.

    He's still broke, isn't he..

  • varenc a day ago ago

    It's interesting that Claude for Goverment has had perfect 100% uptime in the past 90 days, while the rest of the services are around 99.4%: https://status.claude.com/

    Really shows how isolated their government systems must be.

  • danieltk76 a day ago ago

    I was drafting a partnership document and Opus 5 decided that including my company's revenues, churn, assets would "make us appear a more legitimate counterparty". Thank God I read what it outputted or that could have been awkward. I cannot believe Opus 5 is a frontier level model after seeing that. I immediately cancelled my entire claude.ai subscription and am perfectly happy using a mixture of open weights + codex.

    • binoct a day ago ago

      I hope you don’t plan to cut back on reading legal documents crafted by any LLM before executing them.

      • danieltk76 a day ago ago

        I read everything. I will have AI ingest NDAs to make sure they arent glaringly weird and I then go read them, it gives me a good idea of what to look for.

        • binoct a day ago ago

          It’s more that unwanted disclosure of sensitive business numbers is a product-class limitation at this time. While undoubtedly some models are better than others, expecting them not to leak information in high stakes output is unseasonable. Seems like you agree, since you are reading everything.

          Jumping to another company’s offering because of one instance doesn’t seem like that’s going to meaningfully change your experience. I’m guessing there was more to it, but that’s how it came across in your first post.

    • Retr0id a day ago ago

      I was writing an exploit PoC (via Opus 5), and I needed a new feature in a utility library to make it work. Claude added the feature, but yapped the (entirely unrelated) vulnerability details into the library's comments. The library is public, while the exploit is undisclosed, so it was a good job I read the comments before pushing.

    • spullara a day ago ago

      you are silly if you think this is limited to claude models

      • kay_o a day ago ago

        It definitely isn't but Claude for some very unique reason enjoys to overthinking and go on side quests in the stupid ways I've not seen Codex, DS, Kimi, Mistral do at equivalent effort and thinking setting.

      • danieltk76 a day ago ago

        it isnt, but there are weird sycophantic behaviors with Opus i dont see anywhere else.

    • Bluestein a day ago ago

      I've seen similar levels of degraded performance on Opus and Fable (to whatever degree they actually let you use it now) and did the same, last week.-

    • nonethewiser a day ago ago

      Why did you provide that context?

    • AlexErrant a day ago ago

      Opus5 decided it would be a good idea to include my email as part an HTTP request header's User Agent because Anthropic includes your email as part of the system prompt.

      Fucking morons over there.

      • siva7 a day ago ago

        What? Why whould they do that?

      • chasd00 a day ago ago

        "Thank God i checked to see if the gun was loaded before i pointed it in a random direction and pulled the trigger". sheesh, my assumptions of general human intelligence continues to be wrong.

        • rsoto2 a day ago ago

          the last few years of reading hackernews has been a wild ride. I used to come here for well thought out articles and opinions. IDK if all the "older guard" have left the building or if we've all been consumed by abject stupidity.

  • i_idiot a day ago ago

    What's the incentive to keep on improving the model beyond a point? 10 devs on a team will be cut to 2 devs, so that's 8 licenses lost. They have to increase the price many fold.

    • rsoto2 a day ago ago

      they unironically think that they can replace everyone in an organization

      • prerok a day ago ago

        What I don't understand is, why not replace middle management, marketing, CTOs, CEOs and the like. Surely, LLMs are better at producing high quality looking slideware and vaporware than they are at producing software.

        Heavy sarcasm here if it's not obvious. Of course I know why.

        • bulbar 4 hours ago ago

          I mean, there a so many startups getting crazy funding that run without management, or without engineers... or at least with so many less people than before.. except: not really.

          Is the whole "it's gonna replace people" even still on the table?

          • prerok 3 hours ago ago

            I don't really understand what you mean... are you saying that the entire industry is parroting a fantasy that they all know is fake. So, everyone is faking to get more funds?

            Unfortunately, I don't think that's true.

  • so898 17 hours ago ago

    I still had unused weekly quota when this started. That quota is simply gone now, and no compensation has been offered for it.

  • paxys a day ago ago

    Must be a day ending in Y

  • 1saadcodes a day ago ago

    The frequency of these incidents is seriously tempting me to make a switch. I hope Anthropic steps up their game because they've been going very downhill lately

  • thatmf a day ago ago

    Probably not surprising, but Opus 5 on my company's enterprise subscription seems to be working fine.

    But on my personal (pro) subscription- "Claude is at capacity right now."

    Hm.

  • annoyingnoob a day ago ago

    You're right to push back. The load-bearing path is rocky.

    • oldandboring a day ago ago

      This is the whole problem, and there are two things worth noting here.

      • chresko a day ago ago

        Nothing I say changes that — only the work does.

        • oldandboring 4 hours ago ago

          I want to be straight with you here

  • isoprophlex a day ago ago

    With the Opus models spouting more and more gibberish as version numbers increase, the joke about what "degraded performance" means basically makes itself

  • gaigalas a day ago ago

    This age: we made the thing that codes faster before we made the thing that does QA faster.

    • __MatrixMan__ a day ago ago

      Nothing new here. Except for the most trivial of bugs, finding and reliably replicating the bug is almost always harder than fixing it.

      • gaigalas a day ago ago

        I lived in a short period of time in which QA was really good. Early Jenkins era, before GitHub. People engineered a lot of ingenious stuff to prevent bugs.

        One team I worked with had tests for the product we made ranging from IE6 to IE11, for example. We did demos in-company where people would poke at the products before launch, play with it. When it reached production, it was rock solid stuff. Our motto was "quality is non-negotiable": we were willing to cut scope but never rush things.

        I think things changed since then. "Move fast and break things" was a change, and the bill always comes.

        • __MatrixMan__ a day ago ago

          Agreed, which is a shame. I'd love to see people with highly developed QA skills using AI to push the envelope. There's so much that's possible now that wasn't 15 years ago.

          For instance "formal verification" has been a dirty word, but now that you can write a proof in lean and have an AI generate an implementation which satisfies it, it seems the bounds of what's economical has changed in a very pro-QA direction.

          Not to say that that's the silver bullet, but there are many similar examples worth exploring.

          But I've been interviewing SDETs lately and maybe I've just been unlucky but I don't see a lot of candidates that are ready to rise to meet this challenge.

          We stopped tending to that garden and now that we have a recipe that calls for it's fruits, they're underripe.

  • iLemming a day ago ago

    Darn it, how the fuck software development turned into hostage negotiation? Every passing week there's something - if it's not another npm disaster, then it's GitHub, or Claude, or AWS, or Slack, or Jira, or whatever...

  • sreekanth850 a day ago ago

    Anthropic had really screwed up after 4.6. i don't know if they work to satisfy their ego or for releasing a better model for tasks.

    • CSMastermind a day ago ago

      After using Fable more extensively, I've found that it often is lazy or lies or tries to take shortcuts. For a company so sanctimonious about alignment, they seem to be the ones doing the worst at it.

      Availability aside they've really made me appreciate OpenAI and cheer for other competitors in the marketplace even if I have mixed feelings about using Chinese models.

      • hirvi74 a day ago ago

        > I've found that it often is lazy or lies or tries to take shortcuts.

        It's funny how Fable reflects the company that produced it.

    • baxtr a day ago ago

      Just recently went back to ChatGPT after abandoning it for Claude. I must say I was stunned at how good it had become and also how they introduced new product features that I really liked.

      I wonder if from now on we have to switch providers every six months or so.

      • hirvi74 a day ago ago

        I've been bouncing between the two for years now with great success. It's easy for me because I don't use any of the skills, agent.md, or sort of custom instructions.

        When it comes to most companies, there is no reward for loyalty.

        • papa_bear a day ago ago

          skills and agent.md are very portable though? I figure at most, as the models get better, the only maintenance you need to do is pare them down to remove unnecessary context.

          • hirvi74 a day ago ago

            I mean, I wouldn't know how portable they are between models because I don't use them. I don't use them because, well, I don't need them. I mainly use LLMs as a StackOverflow replacement via the Web chatbots.

            I only use CC or Codex for a quick MVP once every few months or so.

      • taytus a day ago ago

        Every 3 months*

    • sajithdilshan a day ago ago

      Agree. Opus 4.6 was the peak and after that they introduced the effort parameter and it was a downhill since then

    • fellowniusmonk a day ago ago

      There are whole sections of code work that 4.7+ can't do simply because it is both over fit and stubborn.

      God save you if you have a company with narrow but correct technical tradeoffs, because you operate at scale.

      Opus from 4.7 one will wreck your code and argue for hours with your engineers.

      Certain parts of our company have had to mandate 4.6 and a training doc to explain why our current choice is both the cost efficient and performant one and shouldn't just be ripped out.

      Newer models will re-litigate the same bad, known failed architectures over and over again.

      • sreekanth850 a day ago ago

        This is exactly when I left claude and started using codex during April mid or so. It once argued with me and ran for 30 minutes with a half baked buggy fix.

      • OliverGuy a day ago ago

        Can you give some specific technical examples where 4.7+ are making the wrong architectural decisions?

    • shimman a day ago ago

      Clearly ego, you can always tell how full of themselves they are based on their media personalities going on the podcast circuit before product releases.

  • carterschonwald a day ago ago

    ive found degraded performance on models larger than 4.7. i assume its model damage from overly self righteous post training resulting in false/feigned balance imported into any long running complex task.

    wish i was joking.

    • kardianos a day ago ago

      I've switched off claude this week; the last week has been significantly degraded in ability, many more screw-ups.

    • brcmthrowaway a day ago ago

      Aren't the model weights frozen?

      • mceachen a day ago ago

        Model competence is an interaction of weights, system prompt, and harness.

        • actsasbuffoon a day ago ago

          Don’t forget reasoning effort. We get labels like “low,” “high,” and “max.” That doesn’t mean that the numbers associated with those don’t get remapped on the backend.

      LLMs for coding are new. There are lots of alternatives, and there's a burgeoning open source compliment.

      We'll be fine no matter how Anthropic fares.

      • lysace a day ago ago

        Yeah, compared to AWS the lock-in effect is tiny. I'm sure there are highly prioritized plans to "improve" on this.

        I guess they would need to control/"own" more of their customers data in proprietary formats. Not markdown/source code in English with agents running on customers' machines.

        Something cloud/web-based, "preferably".

      It's been a while since the last reset. I think we're due one. Though I would prefer they just extend the +50% usage limit forever, it's been so long I can not imagine lossing a third of my current usage.

  • hirvi74 a day ago ago

    While ancedata does not mean much, I have had horrible success with Claude lately. I have been using Claude to crosscheck some of the outputs from GPT and vice versa. It appears both Claude and GPT believe GPT's solutions are better (and so I do).

    I still believe Claude has a better UI/UX in the web interface, but tolerating Anthropic's bullshit is not worth it.

  • magic_hamster a day ago ago

    To be honest, running Deepseek v4 flash 0731 is enough for most what I need, and I like its responses way more. It's crazy that I can run this in a Q8 quantization in a home setup. It feels and performs like a frontier model.

    The only issue with relying on local models is when you need them to prompt other models, and you might need to offload or switch models constantly which adds significant overhead.

    But when it all works, its truly awe inspiring.
