From ab997e04eb4f0f50bc2c6ae738231455cdd97329 Mon Sep 17 00:00:00 2001 From: shivam Date: Sat, 25 Jul 2026 00:09:21 +0000 Subject: [PATCH 01/17] fix(caching): cache anthropic /v1/messages responses, including streaming anthropic_messages was missing from the cache's supported call types, so every /v1/messages request went to the provider. Adding it alone is not enough: the cache key is built from the OpenAI-ish param set, which has no system, top_k or stop_sequences, so two requests differing only by system prompt shared an entry and the second got the first one's answer. The Anthropic Messages request shape now feeds the key set as well. Streaming responses return to the caller before async_set_cache runs, so they are teed on the way out and the SSE events are stored verbatim once the stream reaches message_stop without a provider error. A hit replays those bytes and logs the request as a cache hit with zero cost.

Such a row matched neither the completed-with-output billing branch nor the failed/expired/cancelled branch, so batch_processed stayed False and the poller re-selected it on every cycle for the lifetime of the deployment; output/error file deletion is also gated on batch_processed, so those files could never be deleted. Broaden the terminal handling so a completed/complete/expired batch with an output file is billed, and any terminal batch with nothing to bill (failed/cancelled, or completed/expired with no output) is marked terminal exactly once. Non-terminal statuses (validating/in_progress) are still left for the next poll, and an expired batch that did produce output is now billed.
