Kimi K3 Goes Live on Together AI for Long-Horizon Agent Workloads
Moonshot AI says Kimi K3 is now available through Together AI, offering high-throughput inference for coding agents and production use cases.
Moonshot AI announced that Kimi K3 went live on Together AI on July 27, 2026. Together AI described itself as a Day 0 launch partner for Moonshot’s open frontier model, giving developers access through its inference platform.
Together AI’s model page positions Kimi K3 for extended engineering sessions, research, and document workflows. The model supports native vision and a 1-million-token context window, and uses a mixture-of-experts design with 2.8 trillion total parameters and 16 of 896 experts activated per token.
Kimi’s documentation independently identifies K3 as its flagship model and lists July 27 as the planned release date for the full weights. The available evidence confirms the launch and stated capabilities, but does not establish independent benchmark results or API pricing.

Kimi K3platform.kimi.ai · supportingKimi K3 is Kimi’s most capable flagship model to date, with 2.8 trillion parameters. It is built on Kimi Delta Attention (KDA), a hybrid linear attention mechanism, and Attention Residuals, with native visual understanding and a 1M-token context window. It is the world’s first open-source model in the 3-trillion-parameter class, designed for frontier intelligence scenarios including long-horizon coding, knowledge work, and reasoning.For complete benchmarks and case studies, see the technical blog. Kimi is currently working closely with inference partners and open-source maintainers to align technical details and ensure the model launches reliably across the ecosystem. The full model weights will be released by July 27, 2026. More details on architecture, training, and evaluation will be [...] A 3-trillion-scale open-source model [...] ###
Kimi K3 API | Together AItogether.ai · supporting## About model Kimi K3 is Moonshot AI's most capable model and the first open model at the 3-trillion-parameter class, with 2.8T total parameters activating 16 of 896 experts per token. It is built on Kimi Delta Attention and Attention Residuals, two architectural changes to how information flows across sequence length and model depth, with native vision and a 1-million-token context window. The model is designed for long-horizon work: sustaining extended engineering sessions across large repositories, carrying multi-step research and document tasks end to end, and reading screenshots, charts, and documents inside the same model. It runs at maximum thinking effort at launch, and weights are released under an open license.
