Nemotron 3.5 ASR Streaming 0.6B — ONNX
ONNX Runtime bundle for NVIDIA Nemotron 3.5 ASR Streaming Multilingual 0.6B.
Overview
ONNX export of nvidia/nemotron-3.5-asr-streaming-0.6b, a streaming automatic speech recognition model based on FastConformer + RNNT. It is not a newly trained model.
The ONNX artifacts are sourced from altunenes/parakeet-rs and repackaged here for stable, checksum-verified distribution.

Intended Use
Streaming/chunk-based multilingual ASR for local inference via ONNX Runtime. The streaming-capable design allows long-form audio to be processed incrementally rather than loading the full audio into memory. This redistribution removes the Python, NeMo, Docker, CUDA Toolkit, and Rust runtime requirements of the original release; it can be loaded directly via ONNX Runtime.
Runtime Notes
- Designed for ONNX Runtime compatible runtimes.
- Input: 16 kHz mono audio.
- Architecture: FastConformer encoder + RNNT decoder (streaming-capable).
- Inference: cache-aware chunked streaming; full-sequence mode also supported.
Precision and Packaging
Export tooling, precision, and quantization are recorded in the Source table above. This packaging mirror does not publish independent parity benchmarks; validate on your target execution provider before production use.
Limitations
- Multilingual model; accuracy varies by language and domain.
- No repository-specific ASR quality benchmark is documented here.
- This is a redistribution of a third-party ONNX export; validate checksums before production deployment.
