Struct ModelCapabilities 

pub struct ModelCapabilities {
    pub streaming: bool,
    pub tool_calling: bool,
    pub parallel_tool_calling: bool,
    pub json_schema: bool,
    pub system_messages: bool,
    pub vision: bool,
    pub audio_input: bool,
    pub audio_output: bool,
    pub pdf_input: bool,
    pub prompt_caching: bool,
    pub reasoning: bool,
}

Boolean capability flags advertised for a model.

These let recursive runs gate behavior before dispatch — for example, refusing to hand tools to a sub-agent backed by a model whose tool_calling flag is false.

Fields

streaming: bool

The model supports token streaming.

tool_calling: bool

The model supports tool/function calling.

parallel_tool_calling: bool

The model can request multiple tool calls in a single turn.

json_schema: bool

The model supports JSON-schema-constrained structured output.

system_messages: bool

The model accepts system messages.

vision: bool

The model accepts image input.

audio_input: bool

The model accepts audio input.

audio_output: bool

The model can produce audio output.

pdf_input: bool

The model accepts PDF input.

prompt_caching: bool

The model supports prompt caching.

reasoning: bool

The model exposes explicit reasoning/thinking.
