Kimi K3, Moonshot AI's 2.8-trillion-parameter flagship model, is now available on the Telnyx Inference API. It is the world's first open-source model in the 3-trillion-parameter class, built on Kimi Delta Attention and Attention Residuals with a 1M-token context window and native vision capabilities.
The competitive advantage in AI is shifting from who builds the smartest model to who builds the infrastructure that decides where every request runs, and K3 is evidence that the model side of that equation is solving itself. Kimi K3 is the first open-source model to reach 2.8 trillion parameters, and on benchmarks for coding, reasoning, and agentic knowledge work, it competes with closed-source frontier models from Anthropic and OpenAI, proving that open-source is not far behind the frontier labs, and in some cases is already there.
K3 now runs on Telnyx-owned GPU infrastructure and can be access via the OpenAI-compatible API.
