GLM-5.3-Flash launches as a fully multimodal model with a massive 1 million token context window.
Z.ai officially launched GLM-5.3-Flash, previously previewed under the codename Ox Alpha running entirely on Chinese AI chips. It's a 320 billion parameter model, natively multimodal, and released under the open MIT License.
On six benchmarks it beats rivals like Claude Opus 4.8 and GPT-5.6 Terra in several categories. A leaked preview has now become a fully released, competitively priced open model.
Key Capabilities:

• Huge Context: Supports a 1 million token context window natively, handling very long documents or conversations.
• Fully Open: Released under the MIT License, letting developers use and modify it freely.
• Benchmark Leader: Tops rivals on Terminal Bench 2.1 and AutomationBench among six tested categories.
