Developers on X report that Opus 5 requests in Claude Code are being served by a new 'Opus 5.2' model slug, suggesting Anthropic skipped 5.1 entirely. Early community testers put it near GPT-6 Astra tier for coding. But Anthropic has confirmed nothing, its docs still list claude-opus-5 as current, and no opus-5-2 appears in OpenRouter's catalog. No official pricing exists.
