Why the edge:
- Documentation and upkeep, Granite Speech 5.0 2B +33: 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.); Voxtral Mini 4B Realtime 2602 59 (The card covers intended use, architecture, parameters, context and languages, without limitations or a cut-off (14).)
- Risk, Granite Speech 5.0 2B +10: 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.); Voxtral Mini 4B Realtime 2602 60 (File safety gets the full 25, safetensors only and loaded by the runtimes' own code.)
- Reach, Granite Speech 5.0 2B +5: 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.); Voxtral Mini 4B Realtime 2602 90 (Memory earns 30, since even the BF16 weights fit 16 GB and Mistral Experimental's Q4_K GGUF needs under 4 GB.)
