Opus 5 Leaks
- Claude Opus 5 is expected to launch on July 20-21, with the launch window pointing to next week.
- Opus 5 is to feature a 1M context window and bring capabilities closer to Fable 5, at least on benchmarks.
- It's a bigger and stronger model than Opus 4.8.
- Anthropic is not planning to extend Fable 5 subscriptions beyond July 19, making an Opus 5 launch around that timeframe highly likely.
As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.
Here’s what this means for you:
Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.
On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.
We know this is a disruption to your workflows; we appreciate your patience and support.
