New Model Option: OpenAI GPT-5.2
December 19th, 2025
OpenAI has upgraded their GPT‑5 series with the release of GPT-5.2 Instant and GPT-5.2 Thinking. We now support both as model options in the Agent Builder to optionally choose for your Agents. To learn more, see OpenAI's support docs: https://openai.com/index/introducing-gpt-5-2/
Important note: the GPT-5 series (including, 5, 5.1, 5.2) all have larger context windows than older OpenAI models as well as Anthropic models. The GPT-5 series supports conversations up to 400k tokens, although in some cases may mean a slightly higher price. For a full view of our supported models and their cost + context window support, see our ReadMe doc: https://docs.ninjacat.io/docs/model-selection
