Hanzo Engine is an independent fork: all crates, binaries, and APIs are
Hanzo-branded (hanzo-engine), and Hanzo AI is not affiliated with Mistral AI.

Forked from https://github.com/EricLBuehler/mistral.rs. Upstream history is
retained in full, not squashed: this tree's root commit is upstream's own
1ecfb70842640b12c8321d69be58bec5331ddffc (EricLBuehler, 2024-02-26), and 3,697
of the 5,495 commits reachable from main are authored by Eric Buehler. The
crate rename (mistralrs-* -> hanzo-*) rewrote commit hashes from
7483b396fa0513362977a6e033e5259d1a7319e7 (2024-02-27) onward, so beyond that
point our SHAs no longer equal upstream's even where the content is theirs;
tools/upstream-map.sh maps the paths. Upstream work is merged through
mistral.rs 0a14af4a43e6f61afbed71f72f22c162ab944c0d (PR #2188, 2026-06-02).
Hanzo Engine tracks its own release line (1.7.x) rather than upstream tags.

DEVIATIONS
-------------------------------------------------------------------------------

Hanzo Engine has diverged substantially from upstream mistral.rs:

  - Full Hanzo rebrand: every workspace crate is renamed hanzo-* (hanzo-engine,
    hanzo-server-core, hanzo-router, hanzo-quant, hanzo-vision, hanzo-audio,
    hanzo-paged-attn, hanzo-llm-mcp, hanzo-sandbox, hanzo-code-exec, hanzo-cli,
    hanzo-pyo3, hanzo-film), and the CLI/binary is `hanzo`.
  - Candle is consumed as Hanzo's fork (hanzo-ml, hanzo-nn, hanzo-flash-attn,
    hanzo-metal-kernels) rather than upstream candle-core / candle-nn.
  - OpenAI-compatible `/v1` server plus an Anthropic-compatible
    `POST /v1/messages` endpoint (streaming + tool use), served from one router.
  - All-modality serving: text/chat, vision (hanzo-vision), audio in and 24 kHz
    speech out (hanzo-audio), video and image/diffusion models, long-form film
    orchestration (hanzo-film), and 3D (hanzo-3d).
  - GPU backend coverage across CUDA, Apple Metal, and AMD ROCm/HIP
    (Dockerfile.cuda, Dockerfile.rocm, and the Metal kernels).
  - Broad quantization support: GGUF, ISQ, UQFF, Q8_0/Q4_K, IQ4, MXFP4, HQQ,
    AFQ, and bitsandbytes FP4.
  - Zen model serving (native/zen3-serving and the zen model paths).
  - Adapter primitives: AnyMoE plus LoRA and QLoRA adapters.
  - Hanzo ZAP transport integration (hanzo-engine/src/zap) and a disk-first KV
    cache for cross-restart sessions and agent prefix reuse.
  - Sandboxed local code execution (hanzo-sandbox, hanzo-code-exec) for the
    agentic runtime.
