Overview

Deltafin is a Rust project packaged as a native binary for running the complete, unpruned 2.8-trillion-parameter Kimi K3 model on a single device. It explores local inference for a model intended for large-scale infrastructure while keeping all 16 experts and leaving token decisions to K3. Optional small draft models can propose tokens, which K3 verifies. The project also provides an OpenAI-compatible API server for local chat and coding agents, with support listed for macOS ARM64 and Linux x86-64/aarch64 using Metal/MPS, CUDA, or CPU.

Key features

  • Runs the full, unpruned Kimi K3 model with all 16 experts.
  • Lets optional small draft models suggest tokens, then has K3 verify them.
  • Provides an OpenAI-compatible API server for local chat and coding agents.
  • Lists macOS ARM64 and Linux support with Metal/MPS, CUDA, or CPU.

Best for

Researchers and enthusiasts exploring how to run a very large model locally without pruning it. It also suits people who want an OpenAI-compatible local API for chat or coding agents.
