Why the edge:
- Risk, Nemotron 3.5 ASR Streaming 0.6B +25: Nemotron 3.5 ASR Streaming 0.6B 60 (File safety gets 15, because the NeMo checkpoint beside the safetensors is a pickle that one documented path loads; no repository code runs.); 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…)
- Reach, Nemotron 3.5 ASR Streaming 0.6B +20: Nemotron 3.5 ASR Streaming 0.6B 70 (Memory earns the full 30 because NVIDIA's own Q8_0 GGUF is 0.74 GB and even the F32 safetensors need only about 3 GB.); 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.)
- Agent interface, Nemotron 3.5 ASR Streaming 0.6B +15: Nemotron 3.5 ASR Streaming 0.6B 50 (Read for a speech model, the tool-calling, trained tool calling and structured-output lines stand for what it takes and returns.); Parakeet Unified EN 0.6B 35 (Chat template 0, no chat template and no prompt.)
- Documentation and upkeep, Parakeet Unified EN 0.6B +10: Nemotron 3.5 ASR Streaming 0.6B 69 (The card with its subcards covers intended use, limitations, architecture, parameters and languages, and misses a context length and a cut-off (14).); 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…)
