China’s Moonshot AI releases Kimi K3, the largest open-source model ever, rivaling top U.S. systems

Moonshot AI, the Beijing-based artificial intelligence startup backed by Alibaba, on Thursday released Kimi K3 — a 2.8-trillion-parameter model that the company says is now the largest open-source AI model in the world, and one that benchmarks show performs neck-and-neck with the most powerful proprietary systems from Anthropic and OpenAI.

The release, timed to land just ahead of the 2026 World Artificial Intelligence Conference in Shanghai, is a dramatic escalation in the global AI arms race and a watershed moment for the open-source AI movement. It also marks a remarkable comeback for a company whose market position had eroded significantly over the past 18 months following DeepSeek's meteoric rise.

Kimi K2.7 Code: BEST Open Source Model? REALLY Cheap and
Beats Opus 4.8 and GPT 5.5?

Kimi K2.7 Code might be one of the most impressive open-weight coding models released so far. In this video, we fully test Moonshot AI’s latest coding-focused model and see how it compares against Opus 4.8 Max, GPT-5.5, Fable 5, Qwen 3.7 Max, Grok 4.3, and other top coding models.

Kimi K2.6: BEST Opensource AI Model That Beats Opus 4.6 and Gemini 3.1 Pro

In this video, I fully test Kimi K2.6 across real-world tasks, from long-horizon coding to agent workflows and even front-end website generation. This model isn’t just competitive — it’s going head-to-head with top proprietary models like Opus 4.6 and Gemini 3.1 Pro… and in some cases, outperforming them.

Anthropic says DeepSeek, Moonshot, and MiniMax used 24,000 fake accounts to rip off Claude

Anthropic dropped a bombshell on the artificial intelligence industry Monday, publicly accusing three prominent Chinese AI laboratories — DeepSeek, Moonshot AI, and MiniMax — of orchestrating coordinated, industrial-scale campaigns to siphon capabilities from its Claude models using tens of thousands of fraudulent accounts.

How Moonshot's Kimi K2.5 helps AI builders spin up agent swarms easier than ever

Cinese company Moonshot AI upgraded its open-sourced Kimi K2 model, transforming it into a coding and vision model with an architecture that supports an agent swarm orchestration. 

The new model, Moonshot Kimi K2.5, is a good option for enterprises that want agents that can automatically pass off actions instead of having a framework be a central decision-maker.

Moonshot's Kimi K2 Thinking emerges as leading open source AI, outperforming GPT-5, Claude Sonnet 4.5 on key benchmarks

The Chinese AI startup Moonshot AI’s new Kimi K2 Thinking model, has vaulted past both proprietary and open-weight competitors to claim the top position in reasoning, coding, and agentic-tool benchmarks. 

Despite being fully open-source, the model now outperforms OpenAI’s GPT-5, Anthropic’s Claude Sonnet 4.5 (Thinking mode), and xAI's Grok-4 on several standard evaluations — an inflection point for the competitiveness of open AI systems.

Moonshot AI’s Kimi K2 outperforms GPT-4 in key benchmarks

Moonshot AI, the Chinese artificial intelligence startup behind the popular Kimi chatbot, released an open-source language model on Friday that directly challenges proprietary systems from OpenAI and Anthropic with particularly strong performance on coding and autonomous agent tasks.
