class BetaCapabilitySupport { supported }

Indicates whether a capability is supported.

supported: bool

Whether this capability is supported by the model.

class BetaCompactionCapability { summarize, supported }

summarize: BetaCapabilitySupport { supported }

Whether the summarize compaction type is supported.

supported: bool

Whether this capability is supported by the model.

supported: bool

Whether this capability is supported by the model.

class BetaContextManagementCapability { clear_thinking_20251015, clear_tool_uses_20250919, compact_20260112, supported }

Context management capability details.

clear_thinking_20251015: BetaCapabilitySupport { supported }

Whether the clear_thinking_20251015 strategy is supported.

supported: bool

Whether this capability is supported by the model.

clear_tool_uses_20250919: BetaCapabilitySupport { supported }

Whether the clear_tool_uses_20250919 strategy is supported.

supported: bool

Whether this capability is supported by the model.

compact_20260112: BetaCapabilitySupport { supported }

Whether the compact_20260112 strategy is supported.

supported: bool

Whether this capability is supported by the model.

class BetaEffortCapability { high, low, max, 3 more }

Effort (reasoning_effort) capability details.

class BetaModelCapabilities { batch, citations, code_execution, 8 more }

Model capability information.

class BetaModelInfo { type: :model, id, allowed_fallback_models, 9 more }
type BetaModelLine = :haiku | :sonnet | :opus | 2 more

A Claude model line, such as opus or sonnet. More lines may be added as new values.

One of the following:
:haiku
:sonnet
:opus
:fable
:mythos
class BetaServerToolsCapability { code_execution, supported, web_search }

Web search and code execution tool support, with one entry per tool.

code_execution: BetaCapabilitySupport { supported }

Whether the model supports the code execution tool: true when the model supports at least one version of the tool, not necessarily every version.

supported: bool

Whether this capability is supported by the model.

supported: bool

Whether this capability is supported by the model.

class BetaThinkingCapability { supported, types }

Thinking capability details.

supported: bool

Whether this capability is supported by the model.

types: BetaThinkingTypes { adaptive, disabled, enabled }

Supported thinking type configurations.

adaptive: BetaCapabilitySupport { supported }

Whether the model accepts thinking with type 'adaptive' (the model decides whether and how much to think).

supported: bool

Whether this capability is supported by the model.

disabled: BetaCapabilitySupport { supported }

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.

supported: bool

Whether this capability is supported by the model.

enabled: BetaCapabilitySupport { supported }

Whether the model accepts thinking with type 'enabled' (extended thinking with a caller-set budget_tokens).

supported: bool

Whether this capability is supported by the model.

class BetaThinkingTypes { adaptive, disabled, enabled }

Which thinking.type values the model accepts on requests. Read each key on its own: for example, enabled can be false while disabled is true.

adaptive: BetaCapabilitySupport { supported }

Whether the model accepts thinking with type 'adaptive' (the model decides whether and how much to think).

supported: bool

Whether this capability is supported by the model.

disabled: BetaCapabilitySupport { supported }

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.

supported: bool

Whether this capability is supported by the model.

enabled: BetaCapabilitySupport { supported }

Whether the model accepts thinking with type 'enabled' (extended thinking with a caller-set budget_tokens).

supported: bool

Whether this capability is supported by the model.
