Opus 5.1/5.2 spotted in Claude Code soft launch, release possibly this week

A user reports Claude Code may be soft-launching an unreleased Opus 5.1/5.2: the experience felt distinctly better than Opus 5 and barely dented usage—only 2% of a Max reasoning weekly quota. He speculates the same work on Astra would consume far more, and predicts a public release tomorrow or this week. Anthropic has not confirmed; he also calls on OpenAI to cut Astra pricing or loosen usage limits.
