Hy-MT2 1.8B zh→en translation for OpenASR realtime subtitles — clause-by-clause, fully on-device

Realtime translation pack for the OpenASR runtime — pure-Rust inference, no Python at inference time.

---

✨ Highlights

• 🌐 Realtime zh→en subtitle translation — drives OpenASR's experimental clause-retranslation lane next to live Chinese ASR
• ⚡ Hot-session clause latency in the hundreds of milliseconds — prefix KV-cache reuse keeps warm per-clause retranslation fast on Apple Silicon CPU
• 📦 Byte-identical upstream weights — the Q4_K_M GGUF tensor data is repackaged unmodified at a pinned revision; sha256 and provenance are embedded in the pack
• 🧾 License + NOTICE embedded — the upstream Apache-2.0 LICENSE.txt and the OpenASR modification NOTICE travel inside the pack metadata
• 🎯 Parity-gated packaging — greedy decode token IDs match llama.cpp on the same prompt before release
• 🦀 Native in OpenASR — .oasr packs run with no Python at inference, engineered for peak performance on CPU & GPU

🚀 Quickstart

# 1. Install the OpenASR CLI  ·  https://openasr.org
# 2. Pull the pack
openasr pull hymt2-1.8b:q4km

Realtime translation is an experimental capability: with this pack installed, realtime sessions can enable clause-by-clause zh→en translation alongside live Chinese ASR transcripts.

🧠 About Hy-MT2 1.8B

Hy-MT2 1.8B is Tencent's compact many-to-many translation model from the Hunyuan-MT family. OpenASR packages the upstream Q4_K_M GGUF release as a local .oasr translation pack and uses it for the experimental simultaneous-translation MVP: finalized and in-progress Chinese clauses from realtime ASR are retranslated clause-by-clause into English, with provisional translations superseded as the source clause stabilizes. The MVP contract is zh→en; the pack runs fully on-device through OpenASR's pure-Rust GGML runtime with no Python at inference time.

⚙️ How this pack was made

Repackaged from tencent/Hy-MT2-1.8B-GGUF at a pinned revision with the OpenASR importer:

openasr model-pack import-hymt2-gguf-local <src>.gguf <out>.oasr \
  --package-id hymt2-1.8b \
  --license-file LICENSE.txt --notice-file NOTICE.openasr.txt

The .oasr container is GGUF-backed. The importer verifies the pinned upstream sha256 and splices provenance, license, and notice metadata into the GGUF KV section; the model weights are byte-identical to the upstream GGUF artifact.

⚖️ License

This pack inherits the upstream model's license: Apache-2.0 (source). The upstream LICENSE.txt and the OpenASR modification NOTICE.openasr.txt are embedded in the pack metadata; the only modification is packaging metadata, not weights.

🙏 Acknowledgements

This pack redistributes tencent/Hy-MT2-1.8B-GGUF in OpenASR's .oasr runtime format. Credit for the model architecture, training, and original weights belongs to the upstream Tencent Hunyuan authors. The upstream model is licensed under Apache-2.0; OpenASR packaging retains that license and attribution. The model weights are byte-identical to the upstream GGUF artifact — the only modification is packaging metadata, recorded in the embedded NOTICE.openasr.txt.
