xAI has released Grok 3, a new AI model trained on the Colossus supercluster using ten times the computational power of its predecessor. The release introduces advanced reasoning capabilities, expanded context windows, and new agent functionalities for users.

  • Trained with approximately 200,000 GPUs, Grok 3 achieves 93.3% on AIME and 84.6% on GPQA benchmarks.
  • The model features a one-million-token context window, eight times larger than previous iterations.
  • Users can activate "Think" mode to view step-by-step thought processes during complex reasoning tasks.
  • Grok Agents, including the DeepSearch tool, provide internet access and code interpretation for dynamic problem-solving.
  • A cost-effective variant, Grok 3 mini, is available for STEM tasks requiring less extensive world knowledge.

Grok 3 is currently accessible to X Premium and Premium+ subscribers, with API access planned for the coming weeks.
