Anthropic preparing for potential Claude Opus 5 rollout

Anthropic appears close to a Claude Opus 5 rollout, with signs of limited external access surfacing in a coding tool’s model picker and Google Vertex quotas.

Leaked details point to an early access preview with per-turn controls, safety fallbacks, and a one million token context window.

The model may also include a high-effort mode, though Anthropic has not announced official pricing or a public model ID.

A new flagship Claude could strengthen Anthropic’s premium and enterprise offering and sharpen competition on performance and price.
