copilot: Auto — Copilot's own pick, the only choice a Student plan has — is listed for every Copilot account and works through magpie, as Copilot's clients do it (#256; Discord, CakeJskSUMM: Copilot Student can only use Auto) — Copilot's /models doesn't list Auto; its clients add it themselves (Copilot CLI 1.0.79: {id:"auto",name:"Auto"}, AUTO_MODEL_ID) and ask POST {api}/models/session with {"auto_mode":{"model_hints":["auto"]}} for a session_token, the selected_model and expires_at, each request then naming that model with the token in Copilot-Session-Token. magpie listed no Auto, failed an account whose list left nothing to pick by hand ("Copilot lists no chat model for this account"), and sent "auto" as a model. Now copilot_auto.go keeps the session per GitHub account, asked again two minutes before it expires; the gateway resolves Auto before choosing the API, so a picked model served only on /responses goes there; a body still naming "auto" (the model test) is rewritten; the endpoints of every model Copilot lists, hidden ones too, are kept for the picked one. A reply to "auto" from another model isn't counted as swapped (Cursor's auto too); the Copilot CLI's picker, which offers auto itself, leaves out the listed one. Tested with fakes in a sandbox HOME: provider/copilot_auto_test.go (a Student-like account whose models are all disabled lists [auto], the session body sent as above, requests carry the picked gpt-5-mini and the token, one session reused, renewed near expiry, an object-shaped selected_model, a refusal reported) and gateway/copilot_auto_test.go (a chat request for copilot/auto goes to /responses as gpt-5-mini with the token, two turns one session; fails without the gateway change); served_test gains the auto cases. go vet ./internal/..., go build -tags nogui (and GOOS=linux, GOOS=windows) and go test -tags nogui ./... pass. Not tried with a real Student account: what its /models returns, whether the plain session request suffices (Auto v2's /models/session/intent is not done), and the body is from VS Code's Copilot Chat, not captured traffic.
usage: a Codex, Copilot or catalog-less relay call is priced at its maker's list price, as a Claude account's is (#224 Koohoko: on the Usage page only Claude models show a cost; gpt-6-astra and gpt-6-luna through Codex's ChatGPT account and gemini-3.8-flash and gpt-6-luna through Copilot show tokens and no cost, and the Codex row reads ≈$153+) — the Usage page and the Requests list price a call by the models.dev ids of the provider it went to (Provider.Catalog), and only the Claude account had one (anthropic): Codex's and Copilot's accounts, like Grok's, WorkBuddy's and a relay added without a catalog, have none, so every call they served was counted unpriced although models.dev lists all these models (openai: gpt-6-astra $10/$50, gpt-6-luna $0.1/$0.5; google: gemini-3.8-flash $0.75/$3.75, per million, in the cached catalog). A call is now priced by its provider's catalogs first, as before, else by the first maker among the vendor presets that lists the model (the same makerCatalogs the reasoning levels borrow from), and a call whose provider has gone since is priced by its maker too. The model is matched by its own key first, then without a path or case (a relay's openai/gpt-6-astra is gpt-6-astra), a Bedrock geography, a (variant) or :tag, as the reasoning levels already are (new catalog.PricedBy, Provider.ListPrice, provider.MakerPrice); a model no maker lists (a Cursor or Kiro alias, a relay's own name) stays unpriced and keeps the + as before, no price is made up. Both the Usage summary and the Requests ledger go through the one pricer, so they agree. Tested with a new TestSubscriptionListPrice: calls to codex (gpt-6-astra, gpt-6-luna), copilot (gemini-3.8-flash, gpt-6-luna), claude (claude-opus-5-5) and a relay with no catalog (openai/gpt-6-astra, mystery-1) each get their maker's price in the ledger and the summary, mystery-1 alone unpriced (fails on main: all seven unpriced); TestLedger and TestSummarize unchanged. go build -tags nogui (and GOOS=linux, GOOS=windows), go test -tags nogui ./... pass (TestAddSecondOfPreset failed once in the full run with a fourth provider and passes on its own and in the package run; it doesn't touch pricing). Not tried against the reporter's usage log or in the GUI; the Sessions page's own pricing (internal/sessions) was not looked at.
catalog: fetched again each day magpie stays open, and sooner when a call's model has no price, so a model models.dev lists after magpie started is priced (#224 Koohoko: gpt-6.1-sol shows no cost) — the models.dev catalog, where list prices come from, was fetched only at the app's start (when older than a week), so a magpie left open, or
magpie serve, never learned a new model's price. KeepFresh (internal/catalog/fresh.go), run by the app's backend and by magpie serve, looks every hour and fetches when the cache is older than a day; a call whose model has no price asks for a fetch (catalog.Missing, from usage's pricer) when the cache is older than six hours and none was tried in that time, only in a process keeping it fresh, so CLI commands and tests never fetch on their own. Loading and Reset now share a mutex instead of a sync.Once reassigned under a running Do, which a background Sync could hit while a call was being priced. Tested with fresh_test.go against a fake models.dev in a temp XDG_CACHE_HOME: stale after 25h and not before, Missing fetching nothing when not keeping, fetching once when keeping and gpt-6.1-sol then priced, and not again; passes under -race (failed under -race with the Once). go vet, go build -tags nogui (and GOOS=linux, GOOS=windows) and go test -tags nogui ./... pass.

usage: costs show in RMB at a live rate, when Settings picks it (#212 L1cardo: 添加费用用人名币结算的选项，最好是能根据实时汇率来计算) — the Usage page, the tray panel, the TUI and the CLI all price a call in USD, magpie's list prices being dollars; Settings now has a Currency row (after Usage shows) offering $ USD, kept by default, and ¥ CNY, which converts every one of those at display time only — usage.Totals.Cost and the JSONL records it comes from stay in USD always, and a vendor's own balance (already in its own currency, a relay's ¥) is never touched.
