The honest take

✓ What works

  • Excellent Chinese-language fluency and cultural grounding
  • Free tier is genuinely usable
  • Strong multilingual and reasoning performance
  • Mature developer API and ecosystem

✗ What doesn't

  • English output trails the top US models
  • Data residency is China-based — a compliance flag for some
  • Some features gated to the Chinese app store

Verdict

For Chinese-language work Spark Desk is a top-tier choice and the free tier makes it an easy default. English-heavy teams should benchmark it against GPT and Claude first.
