z.ai's open source GLM-5 achieves record low hallucination rate and leverages new RL 'slime' technique
GLM-5 features 744 billion parameters, achieves record-low hallucination rates, and offers cost-effective AI coding and agentic workflows with open-source MIT licensing.
- Today Zhipu AI released GLM-5, a fifth-generation open-weight model available on its site, GitHub, Hugging Face, and live on OpenRouter on February 11, 2026.
- Positioning GLM-5 as a tool, Zhipu argues it shifts from `vibe coding` to `agentic engineering`, offers MIT license and open weights to avoid vendor lock-in, and trains fully on Huawei Ascend chips for `full independence`.
- Doubling to 744 billion parameters, GLM-5 expands pre-training to 28.5 trillion tokens and uses a Mixture-of-Experts with 40B active parameters plus DeepSeek Sparse Attention preserving 200K context.
- Following the launch, Zhipu raised its GLM Coding Plan price by 30pc and Hong Kong-listed Zhipu shares jumped 30%, while the 744B parameter scale creates deployment and governance hurdles.
- Using APRIL, the new RL stack `slime` and a 35-point improvement on the AA-Omniscience Index led GLM-5 to a record-low hallucination rate, according to Artificial Analysis.

Chinese AI startup Zhupai aka z.ai is back this week with an eye-popping new frontier large language model: GLM-5.The latest in z.ai's ongoing and continually impressive GLM series, it retains an open source MIT License — perfect for enterprise deployment – and, in one of several notable achievements, achieves a record-low hallucination rate on the independent Artificial Analysis Intelligence Index v4.0. With a score of -1 on the AA-Omniscience …
China's Zhipu AI Launches GLM-5 with 30% Price Increase—As Stock Jumps 34%
Last month, the senior AI architect Lynn Cole made a prediction about Zhipu's next model in an interview with Techloy. "4.8 is going to be the best model on the market if it improves as much between 4.7 and 4.8 as it did from 4.6 to 4.7," she said. Zhipu AI skipped 4.8 entirely. On February 11, the company launched GLM-5, a 744-billion-parameter model that ranks first among open-source models on multiple benchmarks. On SWE-bench Verified, which …
