Why the edge:
- Documentation and upkeep, Parakeet Unified EN 0.6B +30: Parakeet Unified EN 0.6B 79 (Model card 14, Intended use, limitations (buffered streaming only, accuracy falling at 160 ms and below), architecture, parameters (600M) and the language are t…); Underdog Bark 3.0 49 (The card misses the audio length it takes and a knowledge cut-off (14).)
- Reach, Underdog Bark 3.0 +15: Parakeet Unified EN 0.6B 50 (Memory 30, the only build is the FP32 NeMo archive, 2.47 GB, and 2.47 GB × 1.2 = 3.0 GB, under 16 GB.); Underdog Bark 3.0 65 (Memory earns the full 30, since model.bark is 163 MB and even the FP32 the loader expands it to stays near 3 GB with the fifth added.)
- Risk, Underdog Bark 3.0 +5: Parakeet Unified EN 0.6B 35 (File safety 0, the only weights file is parakeet-unified-en-0.6b.nemo, a NeMo archive whose weights are a PyTorch checkpoint read with torch.load, a pickle form…); Underdog Bark 3.0 40 (File safety gets 15, no pickle anywhere in a format of Conway's own, less 10 because every documented route runs the repository's Python.)
