Strengths

What it's the best tool for

  • Completely free with no request limits
  • Lightning-fast inference thanks to efficient Mixture-of-Experts design
  • One million token context for analyzing large codebases
  • Excellent performance on coding and reasoning tasks
  • Native Russian language support
Limitations

When to reach for something else

  • No built-in web search — relies only on context from your prompt
  • Text-only model, no image or video generation
  • Budget version — less capable than Pro on complex multi-step reasoning
