Grok 4.20 (multi-agent) · impossibl

Grok 4.20 (multi-agent) is the multi-agent beta snapshot of xAI's Grok 4.20, aimed at deep research tasks. Instead of a single model pass, multiple agents collaborate in parallel on each request, with the same text and image inputs, function calling, structured outputs, and reasoning as its siblings.
