New Model for Agents: GPT 5.1

OpenAI has upgraded their GPT‑5 series with the release of GPT-5.1 Instant and GPT-5.1 Thinking. We now support both as model options in the Agent Builder to optionally choose for your Agents. These models are described by OpenAI as the following, but learn more from their support docs here: https://openai.com/index/gpt-5-1/

GPT‑5.1 Instant: our most-used model, now warmer, more intelligent, and better at following your instructions. GPT‑5.1 Thinking: our advanced reasoning model, now easier to understand and faster on simple tasks, more persistent on complex ones.

Try testing your Agents out w/ GPT-5.1- we'd love to hear your feedback.
