qwen-mtp-chat-runtime

qwen-mtp-chat-runtime

Compiled Swift/Metal runtime binaries for ryoshu/qwen-mtp-chat — a local chat CLI for Qwen 3.8 27B with native multi-token-prediction (MTP) speculative decoding on Apple Silicon.

This is not a model repository. It contains no model weights — only the compiled runtime that loads and drives them. Model weights are hosted separately by their own publisher; see Provenance below.

Contents

Requirements: Apple Silicon Mac, macOS 14+. No Xcode/Swift toolchain needed to run these — they only link system frameworks and the OS Swift runtime.

Provenance

Compiled from Layr-Labs/qwen-3.8-mtp-challenge's MIT-licensed trusted harness (Sources/MLXFastCLI, Sources/MLXFastTrustedHarness, Sources/MLXFastCore, Sources/MLXFastModel, Sources/MLXFastTransform) and its vendored MLX Swift stack (mlx-swift, mlx-swift-lm, swift-transformers; MIT/ Apache-2.0), plus one addition: a chat subcommand for real, streaming, arbitrary-prompt generation over the native-MTP block-decode session, written for ryoshu/qwen-mtp-chat and not part of the upstream challenge's benchmark/scoring surface.

Not an official artifact of, or endorsed by, Layr Labs, Inc., EigenLabs, or the mlxfast challenge organizers. Full attribution: NOTICE.md in the companion GitHub repo.

Model weights (downloaded separately, not hosted here)

install.sh in the companion repo fetches these directly from their publisher:

• Backbone: EigenLabs/Qwen3.8-27B-4bit @ eda45ab47f465d08d6558f0353a2346e2eb9d5b3
• MTP head: EigenLabs/Qwen3.8-27B-MTP-bf16 @ 26a328e070875b0314d652a039b6b59902690f03

Usage

Don't download these files directly — use the installer, which fetches and sha256-verifies everything:

git clone https://github.com/ryoshu/qwen-mtp-chat.git
cd qwen-mtp-chat
./install.sh
./chat.sh --prompt "your question"
