xAI: Grok 4.20 Multi-Agent
Analysis Summary
Grok 4.20 Multi-Agent is a variant of xAI's Grok 4.20 with a 2M token context window, tool use, and vision support. However, it carries no independent benchmark data, making it impossible to assess its reasoning, coding, or agentic performance directly.
The model shares pricing with the benchmarked Grok 4.20 at $1.25 input and $2.50 output, and the 2M context window is a meaningful capability for long-document workflows. Without its own benchmark scores, it cannot be treated as equivalent to the measured Grok 4.20.
Until benchmark data is published, this variant should be considered experimental. Teams interested in Grok's agentic capabilities should use the benchmarked Grok 4.20 as the reference point.
