GLM-5.2 achieves benchmark scores near frontier levels, matching Opus 4.7 in text-only tasks and ranking among the top open models on multiple tests. It is the strongest open model currently available, outperforming predecessors and rivals like GPT-5.5 and Fable, though it falls short on specialized benchmarks like anti-sycophancy and has limited vision capabilities.
GLM-5.2 Is the New Best Open Model
Kimi K3, DeepSeek V4 Pro, and GLM-5.2 compared on benchmarks, license, and serving cost
A comparison of three open-weight sparse Mixture-of-Experts models—Moonshot AI's Kimi K3, DeepSeek V4 Pro, and Zhipu AI's GLM-5.2—evaluates their capabilities, licensing terms, and serving costs for long-horizon coding and agent workloads.
GLM-5.2 is the new leading open weights model on the Artificial Analysis Intelligence Index
GLM-5.2 has been designated as the leading open weights model on the Artificial Analysis Intelligence Index. This recognition reflects its performance and capabilities within the open-source AI model landscape.
GLM 5.2 API Live, Weights on Hugging Face, Ollama Support
GLM 5.2's API is now live, with model weights available on Hugging Face under MIT license and supported by Ollama. The model offers two thinking modes—High and Max—with 1M context length, priced at $1.4 per 1M input tokens and $4.4 per 1M output tokens, matching GLM-5.1.
GLM-5.2 crosses 80% on Terminal-Bench
GLM-5.2 is the first open-weights model to achieve 80% accuracy on Terminal-Bench and outperforms all other available open models. It also surpasses Gemini, positioning it as a frontier-level model at a significantly lower cost.
DeepSeek releases V4-Flash-0731, outperforming V4-Pro at lower cost
DeepSeek has released DeepSeek-V4-Flash-0731, an updated version of its smaller "Flash" model that surpasses the larger DeepSeek-V4-Pro on independent benchmarks. The release utilizes a new fine-tuning process while maintaining the original Mixture-of-Experts architecture with 284 billion total parameters.
