From 73981d477c204ab252e539123dcc221e05a4e2ff Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Thu, 12 Mar 2026 04:28:19 +0000 Subject: [PATCH] fix(tests): make cost tracking and max_tokens tests independent of model_prices JSON - Gemini video cost tests: pass explicit ModelInfo with pricing data to video_generation_cost() instead of relying on get_model_info() lookup, which fails when gemini/veo-3.0-generate-preview is not in the JSON. - Anthropic max_tokens tests: mock get_max_tokens() to return a known value instead of depending on model_prices_and_context_window.json having a specific max_output_tokens for claude-3-5-sonnet-20241022.
