togethercompute · x · 2026-08-02
Together AI published a comprehensive developer guide on deploying and running the Kimi K3 model on their platform.
Core Model Specs:
- Params & Context: Kimi K3 features 2.8 trillion parameters and a 1 million token context window, making it the largest open-weights model released globally to date.
- Architecture: Incorporates under-the-hood architectures like KDA, Attention Residuals, and Stable LatentMoE.
- Capabilities: Designed for frontier intelligence tasks such as long-horizon coding and deep reasoning. It is the first open-weights model competing at the GPT 5.6 Sol and Claude Fable 5 tier.
Deployment & Usage:
- Offers an OpenAI-compatible API supporting reasoning effort, streaming, tool use, and vision.
- The guide includes copy-paste code from initial API calls to production deployment, alongside benchmark comparisons and cost analysis for coding and agentic tasks.
