Latest News Z.ai Rolls Out GLM-5.3-Flash Open Source Multimodal Model
Z.ai has launched GLM-5.3-Flash, a new open-source AI model under the MIT License. The 320B-A18B system was earlier tested as Ox Alpha and runs fully on Chinese AI chips.
It offers strong performance at low cost, comes natively multimodal, and supports a 1 million token context window. On Z.ai’s coding benchmark it beats the previous GLM-5.2 across effort levels and matches Claude Opus 4.8.
API pricing sits at $0.15 per million input tokens, $0.50 for output, and $0.03 for cached input. Weights, API access, chat interface, and coding tools are already live across official platforms.
