Price duplicated model ids by owner, never by file order - #588
Conversation
A model id listed by several models.dev providers resolves to the owning lab's own listing (named by canonical_model_id), else a first-party vendor's in fixed precedence, else the tariff most paid listings agree on, ties broken by provider id. Retired first-party ids stay unpriced. PricingTable also keeps GitHub Copilot's own tariffs, and every cost view looks rates up with the turn's source so Copilot CLI turns price at Copilot's tariff where it lists the model.

- Around line 336-342: Update the billed insertion in flatten so a
github-copilot listing with zero input and output cost is not stored in billed,
while preserving existing behavior for other listings. This allows
PricingTable::rate to use the resolved paid tariff instead of the free listing.

Real-session check: the 27 local Copilot CLI sessions ingested into a scratch ledger + scratch relayhistory store, then
Input, output and cache-create dollars are unchanged; only kimi-k3's cache-read tariff moves ($3/M → $0.30/M). |

A $0/$0 listing is a free tier or plan, so owner, primary-vendor, consensus and Copilot billing tariffs all skip it when any listing is paid. The ghost-surface representative rate counts turns per model and billing provider, so one Copilot turn no longer prices a mixed slice. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Pricing resolution
A model id that several models.dev providers list resolves to one tariff. A $0/$0 listing is a free tier or plan, not a token tariff, so it takes part only when every listing is free. Of the rest, the tariff is chosen in this order (
resolve_tariffincrates/relayburn-sdk/src/analyze/pricing.rs):canonical_model_id(moonshotai/kimi-k3→moonshotai), most-named first, ties by name.anthropic, openai, google, google-vertex, xai— for older first-party ids that carry nocanonical_model_id.primary-model-ids.json(a retired first-party model never inherits a reseller tariff).Provider order in the file never matters; the snapshot now parses into
HashMaps.Billing provider
PricingTablealso keeps GitHub Copilot's own paid listings.billing_provider(SourceKind::CopilotCli)isgithub-copilot, andlookup_model_rate(model, source, pricing)prefers that provider's listing at every lookup step, falling back to the resolved tariff. Every cost view passes the turn's source (cost_for_turn, hotspots, cache expiry, CLAUDE.md attribution, tool-call patterns, tool-output bloat, compaction, ghost surface); context-delta span trees carry no harness and cover only Claude/Codex, so they take the resolved tariff. Other harnesses can reach several providers under one model id, so they take the resolved tariff too. The ghost-surface representative rate counts turns per (model, billing provider), so the most-used pair sets a mixed slice's rate. A ledger-homemodels.dev.jsonoverride replaces both the resolved and the billing-provider tariff of every model it prices.Impact
kimi-k3resolves to Moonshot's tariff: cache reads $0.30/M, not the $3/M of the reseller listed after Moonshot.cost_for_turntakes the SDK's ownPricingTabletype;PricingTablestays unexported, as before.Tests
Synthetic models.dev fixtures with duplicate ids across providers, each asserted in both file orders: owner beats agreeing and outnumbering resellers, owner ranking and fallback, primary-vendor precedence, consensus, provider-id tie-break, free listings never outvoting a paid tariff, free owner, primary and Copilot listings never displacing a paid tariff, billing-provider lookup in every cost view,
insert/ override merge semantics. Real-snapshot regressions:kimi-k3equals Moonshot's listing, its Copilot rate equals Copilot's listing, and a cache-read-heavy Copilotkimi-k3turn costs its tokens at Copilot's tariff. All six new resolution tests fail onorigin/main.🤖 Generated with Claude Code
