Report #27175

[frontier] Exponential latency from sequential vision API calls during multi-step reasoning

Batch all visual queries into single multimodal request with structured output schema, processing all regions of interest in one inference pass

Journey Context:
Agents often implement loops: screenshot → analyze text → find button → screenshot → verify click. Each iteration is a round-trip to the vision model \(500ms-2s each\). With 10 steps, this becomes 10-20 seconds of latency. Instead, the agent should collect all 'visual questions' \(coordinates of all buttons, text of all regions, verification of all states\) into a single request. Modern multimodal models support multiple image inputs and structured JSON output. Send the screenshot once with instructions to extract all needed information in one structured response, then act on that structured data without further vision calls until the next major state change.
