Claude Sonnet 5 leaks in model selector
Rumors and screenshots on social media indicate that Anthropic's upcoming Claude Sonnet 5 model has begun showing up in some users' model selection menus. The leak has sparked significant developer interest and speculation that the model is launching today, which could signal a major leap forward in AI capabilities and end the perceived "AI winter."
The appearance of Claude Sonnet 5 in model selectors is either a classic pre-launch UI leak or a controlled canary rollout, suggesting a release is imminent.
* Early UI leaks or phased rollouts are standard practice to prepare infrastructure before public announcements.
* Developers are highly eager for a major capabilities bump to overcome the recent plateau in LLM coding and reasoning performance.
* A release today would intensify competition among major AI labs, particularly OpenAI and Google.
