Model capabilities - declares what a model supports.

Aligned with enact-providers config.yml capabilities and related fields:

• tool_calls → supports_tools, reasoning → supports_reasoning
• runtime.max_tokens_default, cost.cost_per_1m_input/output etc. map to max_tokens, cost_per_1m_*, cost_per_1m_pixels

Fields

max_tokens: u32

Maximum context window (tokens)

max_output_tokens: u32

Maximum output tokens

supports_streaming: bool

supports_video_generation: bool

Supports video generation

pii_safe: bool

Is PII-safe (no data retention)

cost_per_1m_input: Option<f64>

Cost per 1K input tokens (USD); from config cost.cost_per_1m_input
