  • I just finished reading Incorruptible and a central theme (Anthropic is a case study) is that trust is singularly the most important currency a business has. The past few weeks have done wonders for Anthropic’s marketing but just as much if not more damage to the trust factor. Businesses will continue to use Anthropic because it’s the default and accessible where it matters (AWS, Azure, GCP, Databricks, Snowflake, etc). But the trust factor has dropped. It’ll be interesting to see if they can turn the tide. Maybe Fable will be too awesome for people to care about the past few weeks?

    I don’t agree with this at all. IMO Anthropic has shown that that are willing to take even significant financial hits in order to stand up to their values and mitigate what they consider to be dangers and risks. Some people don’t like that or think it’s just marketing. But that’s exactly what Incorruptible is about: companies that are willing to take a stand, even in the face of overwhelming pressure from competitors, shareholders and naysayers.

  • it’s still significantly far ahead of openai. gpt 5.6 looks like “better 5.5”. fable does not feel like better opus 4.8.

  • Most people don't care about trust anymore, we live in a low trust society where this is to be expected. People gladly line up to be poisoned by fast food restaurants and trade 1/3 of their life for pieces of paper on a daily basis.

  • There is no reason to have less trust in Anthropic. It's not clear they did anything wrong. It's more likely the White House simply tied itself in knots, consistent with the last year and a half of chaos from them.

  • To be honest, given the overwhelming (and unfair, and unreasonable) pressure against them from the Leviathan, which the other companies do not have to deal with, they’re doing pretty damn good. In my mind the trust has actually increased that they can handle bad times and still push forward.

  • So two and a half weeks, and on the workday. I wonder how much Jared had made.

    We'll begin restoring access tomorrow, and will share an update soon.

    We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

  • "Taken Steps"

    Looks like Anthropic paid the Danegeld. Now they'll never get rid of the Dane.

  • South of Watling St you're ok.
    by dboreham
  • I mean, they did eventually get rid of the Danes.

  • Silly me for hoping they'd actually honor their original 14-day promise. Per their latest blog post, they've generously slashed the timeline to 7 days, but wait there's more! It's now limited to 50% of your weekly usage:

      > Fable 5 will be available starting tomorrow, Wednesday, July 1, to users globally... Fable 5 will be included for up to 50% of weekly usage limits through July 7, after which it will be available via usage credits.

  • We lost ten days of the original plan (June 13th through 22nd) and got seven days (July 1st through 7th). You're not counting the portion of the original 14 days we already got.
    by jefftk
  • If they really cared about their image among their user base and wanted to undo a little bit of damage they've already done via various policies and decisions, keeping the limits and duration the same as before the ban (or slightly being more generous with them) would have been a really cheap way for them to do that. Alas...
    by rushi_agrawal
  • Yeah, this seems a bit Scrooge-y after all the trouble which was essentially of their own making. I was expecting them to come back with a better deal as an apology, not a worse one.
    by qingcharles
  • Hi subscription peasants! You have seven days of time and 3.5 days of usage to figure out how to get the most out of Fable while it constantly downgrades to Opus 4.8 every time it thinks about exploits while hardening your code base! Enjoy!
    by matheusmoreira
  • I shudder to think what the definition of "malicious activity" is that they will be reporting to the government. Speech has been severely chilled the last couple of years.

    It's nice that the restriction is going to get lifted but I hope this doesn't make anyone complacent that their coding work is going to be scrutinized by the US government, with AI, when using these models.

  • Fable 5 apparently can't be used for coding? (This is from Anthropic's announcement.)

    > After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8.

    Edit: the above was from their tweet announcement at https://x.com/AnthropicAI/status/2072163884430229756 ... the associated blog post at https://www.anthropic.com/news/redeploying-fable-5 suggests it was just poorly written and coding can still be done with Fable, just with overeager bouncing of "some routine coding and debugging tasks" to Opus.

    by bluepeter
  • From the full announcement

    > The new classifier also comes at the cost of flagging benign requests more often during routine coding and debugging tasks. As with all our safeguards, we’ll continue to refine this to better distinguish genuine misuse from legitimate requests and reduce false positives.

    by mikesurowiec
  • where did you find that? weird coz their post announcing this also mentioned Claude Code:

    > Fable 5 will be available starting tomorrow, Wednesday, July 1, to users globally on the Claude Platform, Claude.ai, Claude Code, and Claude Cowork. For Pro, Max, Team, and select Enterprise plans,1 Fable 5 will be included for up to 50% of weekly usage limits through July 7, after which it will be available via usage credits. We will re-enable access on AWS, Google Cloud, and Microsoft Foundry as quickly as possible.

  • In the press release, they 'kind of' clarify this:

       > The new classifier also comes at the cost of flagging benign requests more often during routine coding and debugging tasks.
    by artisin
  • So, you can't use it for coding, can't use it for 'sensitive' information in chemistry/biology. It follows that it's likely bad for medicine and adjacent topics too.

    What can you use it for? To run a breadth search on Erdos problems?

    by xpct
  • I wonder if they meant to draw a link between cybersecurity coding and debugging specifically or this really will apply to all coding and debugging. If it really is a more general restriction, then this is practically the same as it still being restricted.

    "In the near term" is doing some heavy lifting.

    by AquinasCoder
  • Yes, I am pretty sure it was simply poorly worded.

    They almost definitely mean "you will notice even more false positives during seemingly routine coding/debugging tasks than you did at the initial launch". Which is not surprising, given the ordeal they've been put through. Hopefully it won't be too bad.

    The main depressing thing for me is it's now only 7 days on the subscription, and then full API pricing, with no mention of even a plan to bring it back to the subscription in the future. (The initial launch mentioned two weeks of subscription, then API pricing, then a hope to return it back to the subscription not long after.)

    Here's Fable 5, the strongest model. Actually try to use it to harden your code and it turns into Opus 4.8. You have seven days to use it, and only half of that time's worth in actual usage. Enjoy.

    Looks like it's going to be a thoroughly frustrating experience, even worse than initial rollout. For subscription users, the situation is almost indistinguishable from the export ban.

    by matheusmoreira
  • I bet you that nothing changed with how Fable 5 is run.

    "Anthropic has agreed to proactively detect and address security risks associated with the models" LOL, this was already happening.

    This clown car administration just keeps making shit up and then backpedalling in a way that just leaves everything worse.
