Some digging FAST_MODEL = "google/gemini-3-flash" (fast mode primary) DEEP_MODEL = "openai/gpt-5.4" (deep mode primary) VISION_CLICK_MODEL= "openai/gpt-5.4" (the visual grounder)

fast: gemini-3-flash, falls back to gpt-5.4, 15-min run timeout, max 2 visual calls/step. deep: gpt-5.4, 15-min timeout, max 3 visual calls/step.

Why such a hard timeout, and why not latest models?
