vs DeepSeek V4 Flash 0731
DeepSeek V4 Flash 0731 is the cheaper flash-tier option at $0.030 input and $0.075 output per 1M tokens — a 2.5× input and 3.3× output advantage over GLM-5.3-Flash. DeepSeek does not publish multimodal or vision benchmarks for the 0731 checkpoint; the trade-off is price and context (1.31M tokens) against GLM-5.3-Flash's native image + text input and full vision benchmark matrix.

vs Qwen3.8-Flash
Qwen3.8-Flash is the same multimodal flash tier at 2.1× the input price and 1.9× the output price — $0.160 / $0.470 per 1M tokens versus GLM-5.3-Flash's $0.075 / $0.250. Both are native image + text input, both 1M-class context. The Qwen3.8-Flash advantage is vendor reputation for vision benchmarks; the GLM-5.3-Flash advantage is price.
