What we love

  • Hardest-to-beat price-performance ratio on the API right now
  • Open weights mean self-hosting and finetuning are on the table
  • R1 reasoning model is genuinely competitive for math and code

Where it falls short

  • Chinese hosting raises compliance questions for some enterprises
  • Outputs sometimes refuse politically sensitive China-related queries
  • Less mature SDK and tooling than OpenAI or Anthropic
