Tencent has unveiled Hy4 Preview, a 770-billion-parameter open-source Mixture-of-Experts model that uses a recursive self-improvement loop to boost inference throughput by 31.8%. The release, trained on Tencent's vast product ecosystem, positions the company back in the top tier of China's AI competition.
China's Zhipu AI confirmed that its viral Ox Alpha model, now revealed as GLM-5.3-Flash, is a 320B-parameter mixture-of-experts AI system that ran entirely on 100,000 domestically produced Chinese chips during launch. The geopolitically significant claim about Chinese chip capabilities remains unverified by independent sources.
Thinking Machines has released Inkling-Small, an open-weights Mixture-of-Experts transformer model with 276 billion parameters that achieves performance comparable to its larger predecessor Inkling while being one-quarter the size.
AI startup Thinking Machines Lab, led by former OpenAI CTO Mira Murati, has released Inkling, a 975-billion parameter mixture-of-experts model with open weights designed for enterprise customization and on-premises deployment. The company explicitly positions the model as focused on customizability rather than benchmark dominance.
Sakana AI unveiled Fugu and Fugu Ultra on June 22, 2026, a multi-agent orchestration system that coordinates multiple AI models to match performance of leading models like Anthropic's Fable 5 and Mythos without training its own frontier model. The approach aims to reduce single-vendor dependency in enterprise AI deployments.
