Visit AISeeKing (second channel with more cool local ai stuff): https://www.youtube.com/@aiseeking In this video, I'll be telling you about the Ox Alpha reveal, which Z AI has now officially confirmed as GLM 5.3 Flash. The model is open-weight under an MIT license, extremely cheap through the API, and may be one of the best options yet for running a frontier-adjacent AI model locally. -- Key Takeaways: 🚀 Z AI has officially revealed that the Ox Alpha stealth model was GLM 5.3 Flash. 🔓 GLM 5.3 Flash has been released on Hugging Face with full weights under an MIT license. 🧠 The model is a 320B parameter mixture-of-experts model with only 18B active parameters per token. 💸 API pricing is extremely cheap at 15 cents per million input tokens and 50 cents per million output tokens. 📊 On KingBench, GLM 5.3 Flash scored 63 out of 80, slightly below its stealth Ox Alpha score. 🛠️ It performed especially well on reasoning, math, agentic coding, and local fine-tuning tasks. 💻 The model looks like a strong candidate for local inference on high-memory machines like new Macs and AI boxes. 🇨🇳 Z AI confirmed the entire stealth preview was served on Chinese AI chips using a custom SGLang-based inference stack. 👍 Overall, GLM 5.3 Flash is an impressive open model for cheap API use, local AI, and agentic workflows.
