  • In the API, pricing has been reduced to $8/$40 per million tokens.
  • In agentic programming, the model is comparable to Opus 5.5, but on some benchmarks it costs almost twice as little per task.
  • Fast Mode speeds up generation by up to 2.5× for double the price.
  • The model is already available in Claude and through the API.
