Chinese company releases world's largest open-source AI model

Moonshot AI released Kimi K3, a 2.8 trillion parameter open-source model with 1 million token context window, claiming parity with closed-source frontier models. Chinese open-source AI development is shifting from isolated breakthroughs to coordinated capability advances. If you're building on closed-source APIs—whether for code generation, document analysis, or multimodal reasoning—a free 2.8 trillion parameter model just became available, and Chinese teams can now run it locally without API fees or latency. Your unit economics on per-token pricing just got cheaper for anyone willing to self-host or use local inference.
