Moonshot AI Confirms Kimi K3.1 Is Coming After Teaser and Code Traces

Teaser plus code traces indicate a ready K3.1 model preserving a 1 million‑token context with encoder and tokenizer compatibility for developer tools.

Overview

  • Kimi posted a 24‑second teaser that shows a ‘Model: Kimi K3.1’ label, signaling an imminent public update to the K3 line.
  • Developers found a 'kimi-k3-1' identifier in Moonshot AI’s API registry and Kimi’s platform previews, and an SGLang commit on October 19 added K3.1 chat-encoding support with 107 tests.
  • Independent analysis cited in the coverage points to a specific Hugging Face revision named 'moonshotai/Kimi-K3.1', which suggests a concrete model artifact already exists even before broad publication.
  • Technical traces show K3.1 keeps K3’s 1,000,000‑token context, reuses the same byte-level tokenizer and 16 special tokens, and adds a new 'medium' inference-strength tier plus front-end hints at 3D and multi‑agent features.
  • Follow-up reporting says Moonshot has released K3.1 Pro as the first K3.1 variant with high‑speed and Pro editions, lists API availability and per‑token pricing, and states full model weights will be published by November 4.
