The Short Version
- Limited-time free coding harness: OpenCode Zen — verify the live free rows and model-specific data terms
- Best free API path: NVIDIA NIM for Kimi
- Best local/on-device starting point: Local guide
- Best free frontier reasoning lane: Antigravity or AMP
- Best low-cost coding upgrades to test first: GLM-5.2 when 1M context and supported tools fit, Kimi K2.7 Code when you want the cheaper Kimi coding API lane, plus MiniMax M3 if you want to test a 1M-context Token Plan lane. Use Kimi K3 as a measured Kimi escalation, not a budget default.
