From eee86f1e527195ce00bc52415105b953d3141f04 Mon Sep 17 00:00:00 2001 From: Ben Younes <2910651+ousamabenyounes@users.noreply.github.com> Date: Mon, 10 Aug 2026 12:11:23 +0000 Subject: [PATCH 01/15] fix(vertex_ai): bill Gemini grounding per unique web search query Gemini 3 per_query grounding is billed per unique search query the model executes, ignoring empty queries. _calculate_web_search_requests summed every non-empty webSearchQueries string across grounding metadata items, so repeated queries within a request inflated web_search_requests and overstated cost. Count distinct non-empty queries across items instead.

That id is generated per request (uuid4 when absent), so x-session-affinity carried a different value every time and Fireworks prompt caching never hit; cached_tokens stayed 0 across identical prompts. The None path the original change described was effectively unreachable because of it. Drop the fallback so affinity comes only from an id the caller actually supplied: litellm_session_id, session_id, or metadata.session_id. Callers who were relying on a trace id for affinity can pass litellm_session_id instead, which is stable across the requests they want grouped.
