xAI · Multimodal · Released Mar 2026
A multi-agent variant of xAI's Grok 4.20 with a 2 million token context window, released before Grok 4.3.
- Strengths
- Handles extended context windows and multi-agent workflows that benefit from larger token capacity without requiring the newer Grok 4.5.
- Best for
- Applications that need to coordinate multiple agents or process documents and conversations exceeding 1M tokens, where Grok 4.3's smaller context is a constraint.
- Limitations
- Superseded by Grok 4.3 in reasoning capability; use Grok 4.5 if you need frontier-tier performance or Grok Build 0.1 if your task is primarily code generation.
