simon_willisonJul 18

Simon Willison covers Anthropic's confirmation that Fable 5 becomes a permanent Max/Team Premium benefit at 50% of prior limits, starting Jul 20.

What to watch — open questions

  • Do Pro and Team Standard plans get any expanded Fable 5 access, or does the permanent benefit stay limited to Max/Team Premium?
  • Does the 50%-of-limits cap change as competitive pressure from GPT-5.6 Sol and Kimi K3 continues?
  • Does Anthropic publish further detail on the cyber classifiers/jailbreak severity framework from the Jul 2 post, or does it stay a one-off disclosure?
