[frontier] Why do agents built on separate vision APIs fail at real-time interaction loops?

Migrate to native multimodal endpoints \(GPT-4o, Gemini 1.5\) that process audio/image/text in a single forward pass; if using separate APIs, implement speculative vision pipelining where you preemptively send screenshot candidates while the text model is still reasoning.

Journey Context:
Early multimodal architectures chained GPT-4 \(text\) with GPT-4V \(vision\) via sequential API calls: text model decides to look, calls vision API, waits for response, then continues. This creates a 2-3x latency penalty \(round-trip time\) that breaks the 'agent loop' for real-time tasks like voice assistants or live coding. The frontier is 'native multimodality' \(GPT-4o, Gemini 1.5\+\) where the model 'sees' and 'hears' in the same forward pass as text generation, eliminating the network hop. The trap is building pipeline architectures \(LangChain-style sequential chains\) that assume modality separation. The cost isn't just latency—it's context fragmentation and error accumulation. The fix either unifies the endpoint or pipelines preemptively.
