§ 02Analysis

What the numbers mean

Three tiers against two

Qwen3.7 comes in three API tiers. Qwen3.7 Max is the text-only flagship at $1.475 per million input tokens and $4.425 per million output tokens. Qwen3.7 Plus adds image input at $0.32 and $1.28. Qwen3.7 Flash reads text, images and video for $0.03 and $0.13.

On the GLM side, GLM-5.3 is the text-only flagship at $0.079 and $1.40, and GLM-5.3 Flash reads text, images and video for $0.0052 and $0.1985. At the top tier, GLM-5.3 is cheaper than Qwen3.7 Max on both input and output. At the bottom tier it is a split decision.

The small models: a close race

GLM-5.3 Flash and Qwen3.7 Flash are the most interesting pair. Both read images and video. GLM-5.3 Flash is cheaper on input ($0.0052 against $0.03 per million tokens), while Qwen3.7 Flash is cheaper on output ($0.13 against $0.1985). A chat assistant that writes long answers tilts towards Qwen; a long-document reader tilts towards GLM.

The biggest difference is how much they can write at once. Qwen3.7 Flash lists a maximum output of 65,536 tokens and Qwen3.7 Max and Plus 131,072, while both GLM models list 943,718. For long rewrites or agent runs that produce a lot of text, GLM has far more headroom.

Openness and context

All the GLM models here have official weights on Hugging Face. The OpenRouter listing for the Qwen3.7 tiers does not include a Hugging Face model, so as API products they are closed, even though the wider Qwen family has a long history of open releases.

Context is effectively a tie: Qwen3.7 lists 1,000,000 tokens and GLM 1,048,576.

  • Cheapest input: GLM-5.3 Flash.
  • Cheapest output: Qwen3.7 Flash.
  • Largest output per request: GLM-5.3 and GLM-5.3 Flash.
