Research direction
Compare the existing zai/glm-5.3-flashx catalog entry in models.dev/api.json with the zai-coding-plan catalog. Add the missing model with the supplied plan metadata, then verify that the model appears under the coding-plan provider and matches the existing entry where specified.
Written by the indexing model from the issue text.
Description
Missing model
glm-5.3-flashx is present under the standard zai provider but absent from zai-coding-plan.
Source
- Z.AI docs (GLM-5.3-Flash / GLM-5.3-FlashX share one page): https://docs.z.ai/guides/vlm/glm-5.3-flash
- GLM-5.3-FlashX launched 2026-09-18 as the high-speed serving tier of GLM-5.3-Flash (same weights, up to 200 tok/s output).
- Existing catalog entry with full metadata: https://models.dev/api.json →
.["zai"].models["glm-5.3-flashx"]
Suggested zai-coding-plan entry
Same metadata as the existing zai/glm-5.3-flashx entry, with plan pricing:
- Model ID:
glm-5.3-flashx - Name: GLM-5.3 FlashX
- Modalities: input
text,image,video,pdf/ outputtext attachment: true,tool_call: true,reasoning: true- Limits: context 1,000,000 / output 131,072
- Cost: 0 (plan access is points-based; standard-API list price is $0.37 / $1.25 per 1M input / output)
Note
Z.AI docs currently state that GLM-5.3-FlashX is not yet available on the GLM Coding Plan. Filing this so the entry is ready when Z.AI enables it, and so users granted early access can select it in coding tools. Happy to send a PR against dev if that is the preferred route.
