Kimi K3 rivals Anthropic and OpenAI’s top models at a fraction of the cost. $3 / 1M input tokens. $15 / 1M output. $0.30 / 1M cached You can now route your hardest reasoning to an open model without paying that frontier premium.
Big props @Kimi_Moonshot on the Kimi Delta Attention (KDA) architecture that delivers a 2.5X better scaling efficiency. To unlock frontier performance, we put together: custom kernels for the KDA architecture, FP4 MoE kernels, and adapted decode kernels. Now it goes vroom.
Make Kimi K3 yours with LoRA training on Fireworks Training a model this massive used to be a big project. With Fireworks Training, you can take the best open model in the world and efficiently tune it to your unique workloads, without paying frontier prices or touching a GPU h…
Kimi K3 is live on Fireworks. Day 0, inference and training. US-hosted, and zero data retention. This is the first frontier open model in the 3 trillion parameter class. It sports 1M context, native vision, and reasoning that rivals the top closed models. Boom. https://t.co/ItU…
Kimi K3 on Fireworks AI brings frontier-level intelligence to an open-weight 2.8-trillion parameter model, delivering matching performance to closed alternatives like Opus 5 at up to 5x lower cost per task. Hosted with US-based serverless endpoints and Zero Data Retention (ZDR), …
Fireworks AI now supports private preview access for Serverless LoRA Training on Kimi K3, the world’s first open-weight 2.8-trillion parameter model. Through low-cost, pay-per-token serverless fine-tuning, developers can customize Kimi K3 directly from a laptop—eliminating comple…
