Anthropic may release Claude Sonnet 5.5 within days

September looks like an exciting month for AI, with major new models dropping frequently. And according to recent leaks, Anthropic is nearing the launch of its next significant update. Rumor has it that Claude Sonnet 5.5 is almost ready for release. Trusted leaker "Lyra" on X reports that Anthropic partners have received a second checkpoint, which seems to perform even better than the first stealth build. They also mentioned that it could arrive as soon as early next week, possibly before Monday morning ends.
