Zhipu GLM 5.3 Flash — verify on open.bigmodel.cn | ~$0.22 / $0.72 per 1M in/out | Cheapest GLM chat lane on Keyo |

Prototype free, then meter GLM on the same key
For $0 prototyping on the same key, use glm-5.2:free from /free-models — a $0 fixed-ID twin whose calls draw down your $10 welcome credit (fair-use rate limits). When you meter GLM traffic, switch model= to glm-5.3-flash or glm-5.3 without changing base URL or auth.
Rates and how to call
The GLM family on KeyoAPI covers three chat lanes and two speech lanes on one OpenAI-compatible key: glm-5.3 and glm-5.3-flash for chat, glm-5.2 at its own band, plus GLM-ASR (~$0.007 per request) and GLM-TTS (~$0.014 per request). No separate Zhipu account, no second invoice.
Routing pattern: put glm-5.3-flash under high-volume classification, drafts, and summarization; use glm-5.3 as the everyday product lane; keep glm-5.2 where your stack already pins that exact ID. Rates above are indicative sell prices — confirm live rows on /pricing-list before volume contracts.
How to call: keep your OpenAI SDK and set the base URL to https://www.keyoapi.xyz/v1, then pass model=glm-5.3-flash (or any lane above) to POST /v1/chat/completions with your Bearer key. Read usage.prompt_tokens and usage.completion_tokens from each response to reconcile spend against the table above.
For broader planning: compare GLM rates against OpenAI-class dollars on /openai-api-pricing, DeepSeek on /deepseek-api-pricing, and Claude on /claude-api-pricing — all on the same prepaid wallet. Side-by-side planning: /compare.

FAQ
How do I call the GLM API on KeyoAPI?
Set baseURL to https://www.keyoapi.xyz/v1, Authorization: Bearer YOUR_KEY, and model=glm-5.3, glm-5.3-flash, or glm-5.2 on POST /v1/chat/completions.
Is there a free GLM tier?
Yes — glm-5.2:free is a fixed $0 catalog ID on /free-models, covered by your $10 welcome credit with fair-use rate limits. Switch model= to a metered GLM lane on the same key when you outgrow it.
Do you carry GLM ASR and TTS?
Yes. GLM-ASR (~$0.007 per request) and GLM-TTS (~$0.014 per request) run on the same Keyo key — see /brand/keyo-docs.html for their request shapes.
