Seven Model Response Collection And Comparison

via “multi-model response comparison with side-by-side rendering”

Self-hosted ChatGPT-like UI — supports Ollama/OpenAI, RAG, web search, multi-user, plugins.

Unique: Implements parallel model querying with independent streaming pipelines for each model, allowing responses to arrive at different times without blocking the UI. Uses a tabbed response interface that preserves all responses for comparison and allows selective regeneration of individual model outputs.

vs others: Unlike ChatGPT (single model per conversation) or manual model switching, Open WebUI's multi-model comparison sends parallel requests and renders responses side-by-side, enabling efficient model evaluation without conversation context loss.
