Grok 4.20 Multi-Agent Beta
A specialist Grok model that sends several AI agents to investigate a difficult question in parallel, then combines their work into one researched answer.
Plain-English overview
What Grok 4.20 Multi-Agent Beta actually is
Grok 4.20 Multi-Agent is built for deep research rather than quick chat. A lead agent breaks the question into parts while other agents search, analyze, and cross-check information before the lead produces the final response.
It can work with text and images, and developers can add SpaceXAI's web, X, code, and collection-search tools. The one-million-token context is generous, but multi-agent work can take longer and use more tools than a normal model call.
Good fit for
- Deep research with several lines of inquiry
- Source gathering and cross-checking
- Complex questions that benefit from parallel analysis

Availability
Regions and access stage
Available in beta through the SpaceXAI API for multi-agent research and reasoning.
The current model page lists us-east-1 and us-west-2. Beta interfaces and aliases can change.
Check live availabilityData and training
The route matters.
SpaceXAI says API inputs and outputs are not used for training without explicit permission. Requests are encrypted and retained for 30 days by default; team-level zero data retention is available with feature tradeoffs.
This is a concise reading of the cited provider material, not legal advice. A third-party gateway can have different storage, routing, training, and residency terms from the model maker's direct API.
