Pick Kimi if…
- You need real autonomous-agent capability (plan + execute multi-step tasks), not just chat.
- You want the cheaper option (starts at Free chat; API from $3 / 1M tokens, Grok starts at $30/mo).
- You specifically need 2.8T-param open-weight MoE (16 of 896 experts active) or 1M-token context window, which Grok doesn't ship.
- Your primary use case is Long-document analysis (1M context) or Coding & front-end generation — Grok doesn't list this.
“Kimi K3 is the clearest sign yet that open-weight models have caught the frontier: it tops a major coding leaderboard and ships a million-token context, all with downloadable weights. For teams that need self-hosting, privacy, or freedom from lock-in, it''s now a real frontier option rather than a compromise. The everyday chat app is still maturing versus ChatGPT and Claude, but on capability-per-dollar and openness, K3 is hard to beat.”— Editor’s take
