Fireworks AI has released Kimi K3, an open-source model that demonstrates strong performance, particularly when used in conjunction with Anthropic's Fable 5. In agentic tasks, routing between Kimi K3 and Fable 5 achieved 93% accuracy, outperforming either model individually. While Kimi K3 is competitive with Fable 5 in terms of quality, it offers a significantly lower cost, especially for long agentic loops, making the combined approach a state-of-the-art solution for high-quality, cost-effective AI.
