Conversation
- Add missing claude-opus-5 pricing ($5.00 / $25.00 per 1M input/output tokens, same as Opus 4.8) — it was released before the last pricing update but never added to the cost table, so cost() silently returned None for it. - Add gemini-3.6-flash ($1.50 / $0.15 cached / $7.50) and gemini-3.5-flash-lite ($0.30 / $0.03 cached / $2.50), released by Google on 2026-07-21. Anthropic (aside from the opus-5 gap) and OpenAI pricing checked against current sources and found unchanged since the last update.
