Model overview
GGUF / ggml conversions of the **auxiliary CTC alignment model** that ships *inside* `nvidia/canary-1b-v2`'s `.nemo` tarball, repackaged as a standalone forced-aligner for use with the `nfa-align` CLI from **CrispStrobe/CrispASR@parakeet**. When you download `nvidia/canary-1b-v2` you get a single `canary-1b-v2.nemo` tarball. Inside that tarball there are TWO weight files: That second model is what NVIDIA calls the "auxiliary CTC model" used by NeMo Forced Aligner (NFA) to compute frame-aligned word and segment timestamps for Canary's transcript output. **It's the official NVIDIA-recommended path for getting word-level timestamps from Canary**, since the main encoder–decoder doesn't emit them natively (cross-attention DTW tops out around ~360 ms MAE; CTC forced alignment gives ~30-80 ms).

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
