Report #79080

[frontier] Agents switching between vision and text reasoning modes incur latency spikes and cost penalties due to re-processing image embeddings

Implement modality-batching—group all visual operations \(screenshots, image analysis\) into discrete phases separated by text-only reasoning phases, avoiding rapid modality switching

Journey Context:
Each vision API call incurs ~500-1000ms latency for image encoding plus higher token costs than text. Agents that alternate 'screenshot -> think -> screenshot -> think' suffer multiplicative latency. Batching all visual perception into 'sensing phases' then 'planning phases' reduces API calls and leverages text-only models for intermediate reasoning. Tradeoff: slightly delayed reaction to visual changes, but 3-5x throughput improvement for batch-oriented tasks.
