Why the edge:
- Documentation and upkeep, Granite Speech 5.0 2B +43: Granite Speech 5.0 2B 92 (Model card 17, Intended use, limitations, the architecture, the size, the 16K positions and two-minute segments, and the languages are on the card.); Underdog Bark 3.0 49 (The card misses the audio length it takes and a knowledge cut-off (14).)
- Reach, Granite Speech 5.0 2B +30: Granite Speech 5.0 2B 95 (Memory 30, the smallest build listed that keeps 4 bits is IBM's Q4_K_M GGUF, 1.14 GB with the 1.16 GB audio projector, and 2.30 GB × 1.2 = 2.8 GB, within 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, Granite Speech 5.0 2B +30: Granite Speech 5.0 2B 70 (File safety 25, safetensors and GGUF only, no .bin, .pt or .pth files and no Python in either repository.); 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.)
- Agent interface, Granite Speech 5.0 2B +20: Granite Speech 5.0 2B 55 (Chat template 20, chat_template.jinja in the repository (193 characters).); Underdog Bark 3.0 35 (Read for a speech model, the tool-calling, trained tool calling and structured-output lines stand for what it takes and returns.)
