312 - `between_tools: BetaCapabilitySupport`
313
314 Whether the model accepts thinking with type 'between_tools' (thinking turned off, and any short progress updates the model writes between tool calls come back as thinking blocks). False exactly when a request that sends it gets a 400 from this model. A request that sends 'between_tools' can still be rejected for another reason, such as an effort level the model does not allow with thinking off.

312316 - `disabled: BetaCapabilitySupport`
313317
314 Whether the model accepts thinking with type 'disabled' (thinking turned off). False exactly when a request that sends it gets a 400 from this model. True on a model that does not support thinking.
318 Whether the model accepts thinking with type 'disabled' (thinking turned off). False exactly when a request that sends it gets a 400 from this model. True on a model that does not support thinking. A request that sends 'disabled' can still be rejected for another reason, such as an effort level the model does not allow with thinking off.
