What actually differs
- Context window
- Gemini 3.8 Flash takes 1.0M against 1M — modestly more room in a single request.
- Input price
- Gemini 3.8 Flash at $0.75/M against $3/M — 4.0× cheaper to feed. Standard rates: one of these labs also quotes a lower cached-input tier, which applies only when a prefix is reused — see the full spec below.
- Output price
- Gemini 3.8 Flash at $3.75/M against $15/M — 4.0× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Kimi K3 publishes weights (Modified MIT (commercial use permitted; weights publicly downloadable)); Gemini 3.8 Flash is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
