Report #47992

[frontier] Agents alternating between text reasoning and vision analysis in rapid succession incur severe latency penalties \(2-5x slower\) due to model context switching overhead and separate API calls

Batch all vision inputs into a single 'observation phase' followed by a pure-text 'reasoning phase' using structured output formats, rather than interleaving modalities; implement a two-pass architecture where vision happens once per step, text reasoning iterates on cached vision embeddings

Journey Context:
Early multi-modal agents \(2024\) naively interleaved text and images: 'look at this screenshot, now think, now look at another crop'. Each vision call costs 500-2000ms vs text at 200ms. The pattern emerged from Anthropic's Computer Use implementation which forces a strict 'screenshot -> action' loop without intermediate vision calls. Leading practitioners now cache vision embeddings \(using CLIP or model-specific vision encoders\) and run multiple text reasoning passes against static visual context. Trade-off: You lose the ability to dynamically 'zoom in' based on intermediate reasoning, but gain 3x throughput. Alternative \(streaming vision\) is still vaporware due to technical constraints
