Struct AgentCost 

pub struct AgentCost {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cache_read_tokens: u64,
    pub cache_creation_tokens: u64,
    pub total_usd: f64,
}

Cost breakdown for a single query or session.

cache_read_tokens and cache_creation_tokens were added in 0.2.0 to surface Anthropic prompt-caching effects. They default to 0 for providers that don’t report cache stats (Codex, OpenCode today).

Fields

input_tokens: u64

output_tokens: u64

cache_read_tokens: u64

Tokens served from prompt cache (cheap reads).

cache_creation_tokens: u64

Tokens written to the prompt cache (one-off cost).

total_usd: f64
