Stable since 0.63.0

A single built-in model entry.

Produced by crate::catalog::materialize::materialize from the models.dev catalog. The TOML-based path that previously populated these entries has been removed.

Fields

id: String

Model identifier (e.g., “claude-sonnet-4-20250514”)

name: String

Human-readable model name (e.g., “Claude Sonnet 4”)

api: String

API protocol to use

provider: String

Provider name (e.g., “anthropic”, “openai”)

reasoning: bool

Whether this model supports reasoning/thinking

input: Vec<String>

Supported input modalities

cost_input: f64

Cost per million input tokens (USD)

cost_output: f64

Cost per million output tokens (USD)

cost_cache_read: f64

Cost per million cached read tokens (USD)

cost_cache_write: f64
