    • string

  • effort: optional BetaManagedAgentsEffortLow or BetaManagedAgentsEffortMedium or BetaManagedAgentsEffortHigh or 2 more

    How hard Claude works on each turn. Sets output_config.effort on every Messages call the session makes.

    • BetaManagedAgentsEffortLow object

      Low effort. Favors latency over reasoning depth.

      • type: "low"

    • BetaManagedAgentsEffortMedium object

      Medium effort. Balances latency and reasoning depth.

      • type: "medium"

    • BetaManagedAgentsEffortHigh object

      High effort. Favors reasoning depth.

      • type: "high"

    • BetaManagedAgentsEffortXhigh object

      Extra-high effort. Not all models accept this level.

      • type: "xhigh"

    • BetaManagedAgentsEffortMax object

      Maximum effort. Favors reasoning depth over latency.

      • type: "max"

  • inference_geo: optional string

    Geographic region for model inference. When unset, requests fall through to the workspace's default_inference_geo.

  • speed: optional "standard" or "fast"

    Inference speed mode. fast provides significantly faster output token generation at premium pricing. Not all models support fast; invalid combinations are rejected at create time.

    • "standard"

    • "fast"
