Rumor: Anthropic to Release Claude Opus 5
daniel_mac8 · x · 2026-07-15
A reshared post cited a rumor claiming that Anthropic is preparing to release Claude Opus 5 as early as this week or next.
The leak also highlighted a few key points:
- Current Fable 5 quotas might not be extended beyond July 19;
- A successor to Fable 5 is slated for an August release to compete directly with GPT-6;
- Opus 5 is expected to launch with pricing close to Fable, but slightly cheaper.
Using this rumor as a premise, the original author sparked a discussion on how the AI competitive landscape would shift if Opus 5 proves stronger than GPT-5.6 Sol, slightly weaker than Fable 5, but is priced identically to Opus 4.8.
