GLM-5.3-Flash vs DeepSeek V4-Pro-0813
Values come from GLM-5.3-Flash and DeepSeek V4-Pro-0813, 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
- Identical — both accept 1.0M tokens, so context length is not a reason to pick either.
- Input price
- GLM-5.3-Flash at $0.15/M against $0.66/M — 4.4× 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 $1.98/M — 4.0× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Both publish weights — GLM-5.3-Flash under MIT, DeepSeek V4-Pro-0813 under MIT (open-weight, as reported). Check the licences rather than assuming they permit the same commercial use.
- Recency
- GLM-5.3-Flash shipped 13 days after DeepSeek V4-Pro-0813 (2026-08-26 vs 2026-08-13).
