legit_api · x · 2026-07-24
A user reports that Claude Opus 5 is already showing up for some accounts, apparently labeled as “Opus 4.8” in Claude Web and Claude Code.
- The post claims the model knows things 4.8 does not.
- The biggest visible difference mentioned is better frontend output.
- Another quote says the rollout now appears to be happening across providers.
This is still an unverified rollout report, but it points to an active Claude model update in the wild.
