Model IDs

Reviewed by Proof · Updated September 30, 2026

Definition

A model ID is the exact string, such as luv13/kimi-k3, that you put in the model field of a luv13 request to choose which model answers.

Key takeaways

Every luv13 model id starts with luv13/, followed by a lowercase name with hyphens and dots.
The id isn't the display name. "GLM-5.3 Flash" is luv13/glm-5.3-flash, and "DeepSeek V4-Pro" is luv13/deepseek-v4-pro.
Copy ids from GET /v1/models. Don't retype them.
There are seven ids as of 2026-09-30. The main page for luv13 models is Models; this page covers the format of model ids and the mistakes that break them.

The seven ids

From live GET /v1/models on 2026-09-30, with the display names from luv13.ai/models:

Id	Display name
`luv13/deepseek-v4-pro`	DeepSeek V4-Pro
`luv13/deepseek-v4.1-flash`	DeepSeek V4.1 Flash
`luv13/glm-5.3`	GLM 5.3
`luv13/glm-5.3-flash`	GLM-5.3 Flash
`luv13/kimi-k3`	Kimi K3
`luv13/kimi-k3-fast`	Kimi K3 Fast
`luv13/qwen-3.8-27b`	Qwen 3.8 27B

Easy mistakes

Dropping the prefix. Use luv13/kimi-k3, not kimi-k3.
Swapping dots and hyphens. It's deepseek-v4.1-flash (dot in the version) but deepseek-v4-pro (no dot).
Capital letters. Every id is lowercase.
Using an id from another provider. Only the seven luv13/ ids are listed; use one of them.

Some tools want the model name in a settings box. Paste the full id, including luv13/.

Each display name links to that model's page. The model list is also at Models. Price is on Pricing.
