Long story short: Claude Fable 5 is now in Notion.

It's the model we'd put behind your most complex custom agents and workers. It set new highs on our internal benchmarks for the hardest multi-step work.

Available on Biz and Ent plans.

One thing to know: By default, Notion uses LLMs that do not retain data. But unlike other models, Anthropic retains data for Fable 5 so they can catch risks that only show up across many requests.

That's why Fable 5 is opt-in. Admins can enable it in Settings → Notion AI.

@NotionHQ @claudeai You guys continue to blow my mind with notion ai! Everyone else is rate limiting us, and making us monitor our usage, while ya'll are over there giving us unlimited access to the top models! Notion ai on business plan is probably one of the greatest investments at the moment!

@NotionHQ @claudeai Incredible update. Huge value add for complex agent workflows. @NotionHQ, please consider letting trial accounts test it out so founders can assess the capabilities before pulling the trigger on a Biz/Ent upgrade!

@NotionHQ @claudeai Isn't it a bit too overpowered for notion usual use cases?

@updog_osaka @NotionHQ @claudeai It’s worth it ! Like $20 month for business plan, you get Gemini, ChatGPT, Claude, grok, kimi, and deepseek , unlimited usage

@Techinfovibes @NotionHQ @claudeai admin needs to opt in under settings since this model (unlike others) has a 30 day retention period to operate safety classifiers that detect jailbreaks, novel/complex attacks, and reduce false positives - not for anything else

@NotionHQ @NotionDevs @claudeai Will it be available in notion after July 22, when fable is dropping off the usual Claude plans?

@NotionHQ @claudeai Nice call making Fable 5 opt-in and spelling out the retention tradeoff clearly. That kind of model-by-model transparency makes rollout decisions much easier for admins.
