chatModel

Language models available to users signed in to ArcGIS Online organizations with AI agents enabled. These are used by SDK agents and may be used for language processing in custom agents.

• default — The default model tier, suitable for most general-purpose use cases. At v5.2, this tier uses the gpt-6-sol model.
• advanced — A model tier for tasks that benefit from more advanced capabilities. At v5.2, this tier uses the gpt-6-astra model.
• fast — A model tier for tasks such as classification and summarization, where faster responses are preferred. At v5.2, this tier uses the gpt-6-luna model.

The models in each tier will change from version to version as model providers release new models and retire old ones. Because the retirement and availability of models is determined by model providers, apps built using earlier versions of the JS SDK may unwittingly break within standard support lifecycles. Therefore, you should upgrade agentic applications to the latest versions of the JS SDK as often as possible to keep up with rapid evolutions in the underlying technology.

Note, the same prompt may produce different results when different models are used. Therefore, you should re-evaluate prompts, agent descriptions, and tool descriptions and make appropriate adjustments when changing the model tier for an agent or when you upgrade to a later version of the JS SDK.
