Enum CostSource 

pub enum CostSource {
    Litellm,
    OpenCodeStored(f64),
    CursorStored(f64),
    HermesStored(f64),
    GrokGauge,
}

How a model’s USD cost is resolved.

Different providers carry different authoritative cost sources, so the cost resolver branches on which one applies.

Variants

Litellm

File-based providers: the full LiteLLM lookup (exact → normalized → substring → fuzzy).

OpenCodeStored(f64)

OpenCode: an exact LiteLLM match prices from tokens, otherwise the stored assistant-message cost is used verbatim. No fuzzy guessing, so a novel model like deepseek-v4-pro reports OpenCode’s own cost instead of being priced against a loosely-similar name.

CursorStored(f64)

Caller-supplied Cursor cost used verbatim. Retained for source compatibility; VCT’s local Cursor reader now returns zero stored cost and its display path accepts only exact LiteLLM matches.

HermesStored(f64)

Hermes: same basis as [OpenCodeStored] — an exact LiteLLM match prices from tokens, otherwise Hermes’s own stored cost is used. Hermes often bills novel models LiteLLM can’t price, so its own number is the safest fallback; the map is kept separate so a colliding bare model name can’t cross-contaminate another provider’s cost.

GrokGauge

Grok: the full LiteLLM lookup, but the context-gauge estimate lives entirely in the cache-read bucket, so a matched model whose LiteLLM entry publishes no cache-read price (null for several xai/grok-* variants) falls back to the input rate instead of silently costing $0.
