## Replacement

- **GPT-5.6 Sol** (`gpt-5.6-sol`) · recommended — https://modeldeprecations.dev/openai/gpt-5.6-sol
  - Sol is a reasoning model, so budget output with max_completion_tokens rather than max_tokens, and expect reasoning_effort to dominate both cost and latency. Re-tune it before comparing prices.
  - Parameters it accepts: https://modelparams.dev/models/openai/gpt-5.6-sol
