Chinese AI startup Z.ai (formerly Zhipu AI) has released GLM-5.2, a 753-billion parameter open-weight language model that achieved the highest score (51) among open models on the Artificial Analysis Intelligence Index and reportedly outperforms GPT-5.5 on long-horizon coding benchmarks at one-sixth the cost. The model features a 1-million token context window and is available under MIT license on Hugging Face.
Shanghai-based AI company MiniMax has unveiled its M3 flagship model designed for coding agents and automated workflows, featuring a one-million-token context window. The launch enters the competitive open-source AI coding space, though the company has stopped short of a full open-source commitment.
Miami-based AI startup Subquadratic announced a $29 million seed funding round and launched SubQ 1M-Preview, described as the first fully subquadratic large language model architecture designed for efficient long-context processing.
Chinese AI startup DeepSeek released preview versions of its V4-Pro and V4-Flash models featuring up to 1.6 trillion parameters and one-million-token context windows, claiming to close the gap with frontier models while maintaining significantly lower pricing than US competitors.
Google's DeepMind released Gemma 4, a family of four open-weight AI models ranging from edge devices to workstations, marking the first time Google has used the fully open Apache 2.0 license instead of its previous restricted licensing. The models support up to 256K context windows and 140+ languages.
