GLM-5.3-Flash vs Gemini 3.7 Flash
Values come from GLM-5.3-Flash and Gemini 3.7 Flash, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Context window
- GLM-5.3-Flash takes 1.0M against 1M — modestly more room in a single request.
- Input price
- GLM-5.3-Flash at $0.15/M against $0.75/M — 5.0× 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
- GLM-5.3-Flash at $0.5/M against $3.75/M — 7.5× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- GLM-5.3-Flash publishes weights (MIT); Gemini 3.7 Flash is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- GLM-5.3-Flash shipped 13 days after Gemini 3.7 Flash (2026-08-26 vs 2026-08-13).
