Xing4.0-29B-A4B from China Telecom's TeleAI team runs free on OpenRouter: 262,144-token context at $0 input and output. The open-weight mixture-of-experts model (29B total, 4B active per token) succeeds the TeleChat series and ships under Apache 2.0, with weights on Hugging Face; OpenRouter added the free endpoint on October 16. The catch: free-tier OpenRouter models run under shared rate limits, and the endpoint is new enough that availability can change without notice. How to claim: 1) Create an OpenRouter account → 2) Call the model xingchen-agi/xing4.0-29b-a4b:free via API or the model page → 3) Stay within the free quota. Deadline: Ongoing.
