Need a free, high‑accuracy speech‑to‑text solution that can be run locally or via free demos.

Рабочий процесс

• 1. Choose a free route: NVIDIA Space demo, community Spaces, or self‑hosted weights.
• 2. For Space demo: open https://huggingface.co/spaces/nvidia/nemotron-transcribe, select a tab (Karaoke, Podcast, Subtitles), upload or link a sample, run and view output.
• 3. For self‑hosted: install transformers via pip, load model with AutoModelForMultimodalLM and AutoProcessor, prepare audio file, call processor.apply_transcription_request, generate, and decode output.
• 4. For batch or production: deploy with vLLM 0.32.0 and NeMo Speech plugin to expose an OpenAI‑compatible endpoint.
• 5. Monitor GPU usage and choose appropriate precision (BF16, FP8, NVFP4) based on hardware (H100, A100, RTX 5090).
