* feat(passthrough): let upstreams report the model name via x-litellm-upstream-model A pass-through upstream that prices its own requests already reports cost and tokens in x-litellm-response-cost / x-litellm-total-tokens. Product endpoints that take no `model` in the body still landed under `unknown`, so their spend could not be broken down. When the upstream sends x-litellm-upstream-model, record its value as the request's model on success and failure rows, overriding any body `model`. The name is a label only: it never marks the request as upstream-priced and is not used to look up a price. A blank or missing header changes nothing. Refs LIT-9910 * fix(passthrough): keep the upstream-reported model name bounded The upstream model name becomes a spend row, a daily rollup key and a metric label. Use only the first element of a repeated header (RFC 9110 field combining, which is how httpx joins it) and cut the name to MAX_SPEND_LOG_MODEL_NAME_LENGTH, the limit the spend log already applies to model names. Refs LIT-9910 * test(passthrough): cover x-litellm-upstream-model through spend rows and rollups Drives a config-defined pass-through against a scripted upstream and reads back the spend row, the daily team rollup and /team/daily/activity. Covers the header winning over a body model on buffered and streamed responses, failure rows, a model-only header keeping cost_per_request, the no-header and blank header cases, and repeated or long header values. Refs LIT-9910 * test(passthrough): annotate new test locals with Final Refs LIT-9910 |
