@levelsio Whata shame

There's an issue with the selected model (claude-fable-5). It may not exist or you may not have access to it. Run /model to pick a different model. 😭😭😭

@MiniMax_AI Open labs flexing on Anthropic lol

M3 would never 🙂‍↔️ As a matter of fact, the weights are now open, too. huggingface.co/MiniMaxAI/Mini…

GitHub + APK download: lnkd.in/emH5QtNS

and spaced repetition for weak cards. Curious what people think of this approach. Also, for now there is just the AI engeneering pack, if you want to contribute to create more pack, feel free to contact me. Hope this help you 😊

There are so many great resources for learning and interview preparation on GitHub.However, let’s be honest: who really has the time and consistency to keep learning from them every day? I might have just found a solution to that.

What a plot twist

updated fable eval scores

@banteg Just crazy

@AnthropicAI They were asking for controlled development.. they just got what they wanted 🤣

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

@MatthewBerman Cool stuff

4 awesome open-source AI projects: 🔸 /last30days (new search engine) 🔸 agent-skills (full dev skills) 🔸 open-notebook (local notebook lm) 🔸 headroom (save 90% on AI bills)

@OpenAI Great initiative

We heard you wanted to use Codex rate limit resets on your own time. Starting today, we’re rolling out the ability to save rate limit resets to use later. We’re starting Go, Plus, Pro, and Business users with one free reset:

@jshobrook I think at this point they care if it is too secure to answer basic questions because those questions can be answered by their other models.. You would typically use this one for heavy coding or crazy big projects and not chit chat..

For a model that’s “dangerously good” at training models, its safety classifier is surprisingly bad

@sama What do you think of Fable 5?

@karpathy Is it a money burning machine though?

This is a super exciting release - Claude Fable 5 is the same underlying model as Mythos but with added safeguards. The benchmarks are great and it's SOTA on everything by a margin but I'll add that *qualitatively* also, this is a major-version-bump-deserving step change forward (imo of the same order as Claude 4.5 was in November), peaking especially for long problem-solving sessions on very difficult problems. You can give it a lot more ambitious tasks than what you're used to, the model "gets it" and it will just go, and it's never felt this tempting to stop looking at the code at all (but don't do this in prod!). The model still has quirks that people will run into and the safeguards are configured to be a little too trigger happy for launch, which can hopefully be tuned over time. I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything! "Free your mind" (Matrix ref). Really looking forward to all the things people build!

@MatthewBerman Nice summary were they the ones who came to you for testing?

@claudeai Prices?

Fable 5 is state-of-the-art on nearly all tested benchmarks, with exceptional performance in software engineering, knowledge work, scientific research, and vision. The longer and more complex the task, the larger Fable 5’s lead over our other models.

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.

CLAUDE 5 Fable

@kimmonismus If this is True these are crazy scores

Claude 5 Fable Benchmarks! Holy moly, significant jump even to Mythos
