Claude Opus 4.5: verification-status update only: no current model specification, pricing, availability or benchmark change was independently established

The OnAirToday AI Progress Tracker recorded a verified change to Anthropic's Claude Opus 4.5 (version claude-opus-4-5-20251101): Verification-status update only: no current model specification, pricing, availability or benchmark change was independently established.

Live source retrieval is unavailable in this session, so Claude Opus 4.5’s current specifications, pricing, availability and benchmark results could not be independently rechecked. The incidents below reflect supplied reporting about the Claude family, not verified Opus 4.5 involvement; unknown fields are left empty rather than presenting the stored snapshot as current evidence.

What changed in this review:

• Cleared unrechecked specifications and the launch benchmark from current-value fields; this does not establish that their historical values were incorrect.
• Added supplied family-level incident reports with explicit attribution limits; repeated OpenAI coverage represents one reported case.
• Supplied coverage names later Opus versions, but their release status could not be independently verified.
• Excluded tracker summaries, product launches, benchmark coverage and Zcash vulnerability discovery because supplied excerpts do not establish additional qualifying incidents.
• Risks and threats updated

Teams building on Claude Opus 4.5 should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.
