No idea on feasibility given reliance on external APIs, but it would be convenient if each model understood which messages it did or didn’t send within a thread.

Scenario

1. I select GPT-4o as the model, and I ask “Why is the sky blue?”

2. I wait for, and eventually vet GPT-4o’s response.

3. Skeptical of GPT-4o’s response, I switch the model to DeepSeek within the same thread, and ask “what do you think about GPT-4o’s answer?”

current behavior

From what I can tell, DeepSeek doesn’t understand that GPT-4o sent the previous response. Each model assumes ownership of every reply sent in response to user messages within a thread, irregardless of which model actually sent each reply.

This ostensibly has a negative effect on each model’s reasoning capabilities, as they spend time defending/justifying/correcting something they never said.
