Strengths

  • xAI flagship, strong on coding, agentic tasks and STEM knowledge work
  • Competitive agentic coding: 83.3 on Terminal-Bench 2.1 and 64.7 on SWE-bench Pro (single-model)
  • Notably token-efficient on agentic coding versus comparable flagships, at about 80 tokens/second (per xAI)
  • 500K-token context window with multimodal (text, image) input, function calling, web and X search, and code execution

Limitations

  • xAI published only coding and agentic benchmarks; no MMLU, GPQA, math or reasoning scores to gauge broader capability
  • Trails the current SWE-bench Pro coding leaders (64.7 vs about 80)
  • Smaller third-party tooling ecosystem than OpenAI or Anthropic
