Alibaba has released Qwen 3.8, a 2.4 trillion parameter open-weight model that the company claims trails only Fable 5. The multimodal model processes images, videos, and documents, with a preview available through Alibaba's platforms at 10 percent of standard pricing.

Moonshot AI's Kimi K3 model has claimed first place in the Code Arena frontend benchmark with a score of 1,679, surpassing Claude Fable 5 (1,631) and GPT-5.6 Sol (1,618). However, the model achieves only 39% accuracy on FrontierMath Tier 4, while top Western models from OpenAI and Anthropic reach near 90% on the same expert-level math tasks.

Moonshot AI released Kimi K3 on July 16, 2026, a 2.8 trillion parameter mixture-of-experts model that ranks #2 on the Vals AI index and #3 on Artificial Analysis's Intelligence Index. The company will release the model's weights on July 27, making it the strongest open-weight model to date, surpassing all previous open releases including DeepSeek R1.

Within days, Moonshot AI and Alibaba unveiled what they claim are frontier-class models. Moonshot's Kimi K3, at 2.8 trillion parameters, and Alibaba's Qwen3.8, at 2.4 trillion parameters, will both be released as open-weight models with full weights available for download.

Moonshot AI released Kimi K3 on July 16, 2025, an open-weight model with 2.8 trillion parameters. The model represents the largest openly available model by parameter count, entering what the industry categorizes as the 3T class.

Chinese company Moonshot AI released Kimi K3, an open source model that the company claims demonstrates frontier-level performance while trailing only Claude Fable 5 and GPT 5.6 Sol. Independent analyses from Arena.ai and Vals AI suggest the model is competitive with flagship frontier models, reigniting debate about Chinese AI capabilities and open source model development.

Beijing-based Moonshot AI released its Kimi K3 model Friday, which topped Arena's front-end coding capability rankings. The model is priced at half the cost of OpenAI's GPT-5.6 Sol, according to Bank of America research analysts, marking what Arena CEO calls "the single biggest release of the year."

Chinese AI models from Tencent, Xiaomi, DeepSeek, MiniMax and Z.ai now occupy the top five positions by weekly token usage on OpenRouter, a major AI marketplace. The shift threatens to commoditize premium models from OpenAI and Anthropic as businesses reserve expensive frontier systems for only their hardest problems.

Moonshot AI's Kimi K3 model has matched or exceeded performance of Anthropic's Opus 4.8 and OpenAI's GPT-5.6 Sol in independent benchmarks while costing 40% less than comparable US models. The Beijing-based company plans to release Kimi K3 as an open-weight model on July 27.

Moonshot AI released Kimi K3 on July 16, 2026, featuring 2.7 trillion parameters—the largest open-weight model to date. The company claims K3 performs competitively with Anthropic's Fable 5 while costing $15 per million output tokens compared to Fable's $50.

Moonshot AI will release Kimi K3 in the coming days with a parameter count between 2 trillion and 3 trillion, according to Financial Times sources. The open-weight model is expected to perform at par with or surpass Anthropic's Claude Opus 4.8, making it the largest open-weight AI model from China.

GitHub has extended access to Moonshot AI's Kimi K2.7 model to Copilot Business and Enterprise customers. The model was initially made available to Copilot Pro, Pro+, and Max plans on July 1, 2026.

Moonshot AI has released Kimi K2.7 Code, a 1 trillion parameter Mixture-of-Experts model designed for long-horizon coding tasks. The model features a 256K context window and reduces thinking token usage by approximately 30% compared to its predecessor K2.6.

Moonshot AI has released Kimi K2.6, an open-source multimodal model with 1 trillion total parameters (32B activated) and 256K context window. The model achieves 80.2% on SWE-Bench Verified, 58.6% on SWE-Bench Pro, and supports horizontal scaling to 300 sub-agents executing 4,000 coordinated steps.
