Report #74085

[frontier] Real-time agent loops fail when switching between text reasoning and vision analysis causes API latency spikes

Maintain persistent vision model connections using native multi-modal streaming APIs \(OpenAI Realtime, Gemini Live\) rather than switching between text-completions and vision endpoints; collocate reasoning and vision in single model call

Journey Context:
Architectures that chain text LLM reasoning → vision analysis → text reasoning incur cold-start penalties on each modal switch. Standard REST APIs initialize connections per request; vision models often have longer initialization. In agent loops requiring rapid visual feedback \(click → observe → decide\), this creates 1-3s dead time per cycle. The fix shifts to persistent connection streaming APIs where the model maintains state across modalities, or collocates vision and text in a single endpoint call rather than chaining separate services. This eliminates connection overhead and allows the model to maintain attention across modal boundaries.
