Is Pony Alpha GLM-5? What OpenRouter Confirmed
Yes. OpenRouter identifies Pony Alpha as an early testing version of GLM-5. The Pony Alpha listing now points readers to the released GLM-5 model. GLM-5 is a Z.AI foundation model, according to Z.AI's documentation.
The wording “early testing version” matters. It establishes the relationship between the model names; it does not promise that the old and released endpoints return identical answers, share pricing, or follow the same provider terms.

The short history
| Stage | What the provider shows |
|---|---|
| Test listing | OpenRouter lists openrouter/pony-alpha and dates its release February 6, 2026. |
| Identity disclosure | OpenRouter labels it an early testing version of GLM-5. |
| Released model | OpenRouter provides a separate z-ai/glm-5 listing and points to it from the Pony Alpha page. |
Those dates and labels come from OpenRouter's Pony Alpha and GLM-5 listings. They describe provider listings, not necessarily every stage of Z.AI's internal development.
Who created Pony Alpha?
The most precise supported answer is: OpenRouter says Pony Alpha was an early version of Z.AI's GLM-5. Z.AI documents GLM-5 as its own model. It is no longer accurate to present the released model's maker as an unresolved mystery. We cannot infer unpublished details of the test build's training or changes from the identity notice alone.

What is GLM-5 designed to do?
Z.AI describes GLM-5 as a text-in, text-out model designed for coding and longer agent tasks. Its documentation includes function calling, structured output, and a 200K context specification. These are documented features, not proof that it wins every benchmark or fits every use case. For a practical evaluation, see Pony Alpha for coding.
Are Pony Alpha and GLM-5 identical in use?
Treat them as related listings with potentially different behavior and terms. The old model ID and released model ID differ. Context, provider selection, pricing, limits, outputs, and availability should be checked on the live pages. If you have old Pony Alpha prompts, rerun a representative set against GLM-5 and compare real task outcomes before moving an application.
Can I still use the old Pony Alpha ID?
OpenRouter's historical page remains visible, but that alone does not confirm whether openrouter/pony-alpha currently accepts new requests. Check the provider's status and your API response. For new access, open GLM-5 on OpenRouter; our OpenRouter access guide explains the two IDs.
Is GLM-5 free like the old test listing?
The test's historical price is not a promise about the released model. Prices can depend on your access provider and can change. See the current OpenRouter listing, Z.AI's pricing page, and our Pony Alpha pricing guide.
