What is Multi-LLM chat?

Last updated: 2026-05-05

Definition

Multi-LLM chat is a chat interface that lets you switch between multiple large language model vendors — OpenAI (GPT), Anthropic (Claude), Google (Gemini), Mistral, and others — inside a single conversation thread. You pick the model best suited to the next turn instead of being locked into one vendor for the whole task.

Why Multi-LLM chat matters

No single LLM is best at everything. Anthropic Claude tends to win on long-context document analysis; OpenAI GPT-4o on tool calling and structured outputs; Google Gemini on Google-Workspace-grounded tasks; Mistral on cost-efficient European deployments. Multi-LLM chat lets you pick per turn instead of choosing one vendor for the entire workflow — better answers, no vendor lock-in, transparent comparative costs.

How Multi-LLM chat works

  1. 1Configure access to multiple model vendors in one workspace (typically through provider-managed keys on the platform).
  2. 2Start a chat thread; the platform applies a default model based on the user's preference or organizational policy.
  3. 3On any turn, choose a different model from a dropdown — Claude for nuance, GPT for tool calls, Gemini for Google data.
  4. 4The thread continues seamlessly; previous turns from other models are passed to the new model as context.
  5. 5Costs from each model show up live in a unified wallet, billed in your local currency.
  6. 6Optional: define agent-level rules that pick the model automatically based on the task.

Examples

  • A research-and-write workflow that uses Claude for the first-pass analysis (long context), then switches to GPT-4o for structured data extraction, then Gemini for fact-checking against Google Search.
  • A support-triage chat that uses Mistral on the first turn (low cost) and only escalates to Claude when the issue is complex.
  • A multi-LLM "battle" where the user sends the same prompt to two models in parallel and compares answers before deciding.

FAQ

Multi-LLM chat — common questions

Why use multi-LLM chat instead of just one model?
Different models have different strengths. Switching mid-conversation lets you use Claude for nuanced reading, GPT for structured outputs, Gemini for Google-grounded answers, and Mistral for cost-efficient runs — without juggling separate accounts or losing the conversation thread.
How does AgentWorks bill across multiple LLMs?
One wallet, in EUR. Per-token costs are passed through transparently from each model vendor with no markup. The wallet shows live spend per turn so you know exactly what each model costs as you switch between them.
Does switching models lose conversation context?
No. The conversation history is sent to whichever model you pick on the next turn (within that model's context-window limits). The user experience is one continuous thread; the model assignment is per turn.
Which models does AgentWorks multi-LLM chat support?
OpenAI (GPT-4o, GPT-4o-mini), Anthropic (Claude Opus, Claude Sonnet, Claude Haiku), Google (Gemini Pro), and Mistral (Mistral Large). Local and on-premise model options are available on Enterprise.
