Nobody independent has published results for it in at least two areas yet, so its weight is shared across the other four and the total is capped at 61 until they do or our own runs start.\n- Reach 95 (checked 2026-11-10): 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. IBM recommends Q8_0, 3.12 GB with the projector. Runtimes 20, Released Transformers 5.22.2 and vLLM 0.33.0 have the granite_speech model, llama.cpp b12242 has its converter and audio front end, and Ollama carries it as ibm/granite5-speech, which the card says was tested with v0.40.15. Builds 15, IBM publishes GGUF builds at fourteen quantised precisions, from Q2_K to Q8_0, with the audio projector. Terms 15, Apache 2.0 in the metadata and on the card, with nothing added. Download 10, the Hub API reports gated false for both repositories on 10 November 2026, so the files download with no account and nothing to accept. Hosted 5, IBM runs a Hugging Face Inference Endpoint that serves this model through an OpenAI-compatible API, with the address and code on the card. 30 + 20 + 15 + 15 + 10 + 5 = 95.\n- Risk 70 (checked 2026-11-10): File safety 25, safetensors and GGUF only, no .bin, .pt or .pth files and no Python in either repository. Provenance 15, the files sit in the ibm-granite organisation, which IBM's Granite docs link to (10). Safety evaluation 0, no safety results on the card. Agent guidance 10, the card says what the model does with a prompt it doesn't know: it ignores an unfamiliar or malformed prompt and transcribes, which it says limits how audio can steer the system. Licence risk 15, Apache 2.0 with no use policy, no threshold and no right to change the terms. Security programme 5, www.ibm.com/.well-known/security.txt names IBM PSIRT, read for the Granite 4.2 3B listing on 4 November 2026 (5). 25 + 15 + 0 + 10 + 15 + 5 = 70.\n- Agent interface 55 (checked 2026-11-10): Chat template 20, chat_template.jinja in the repository (193 characters). Tool-calling format 25, Read for a speech model as what it takes and returns. Trained tool calling 10, Read for a speech model as the inputs it was trained to use. Structured output 0, Read for a speech model as typed outputs. Reasoning control 0, A speech model with no reasoning. Context 0, the language model is extended to 16K positions, per the card and config.json (16,384), below the 32K band, and the card says to send audio in segments of about two minutes. 20 + 25 + 10 + 0 + 0 + 0 = 55.\n- Documentation and upkeep 92 (checked 2026-11-10): Model card 17, Intended use, limitations, the architecture, the size, the 16K positions and two-minute segments, and the languages are on the card. Training data 20, the data is listed with sources and sizes: a 39-row table giving each corpus, its task, its hours and a link to where it comes from, with the synthetic sets described. Last change 20, the last commit, on 6 November 2026, updated the card, 4 days before this check. Responsiveness 20, Both discussions that aren't pull requests (21 and 28 October 2026) have a reply from an ibm-granite member. Version policy 5, granite-speech-4.1-2b stays in its own repository and 5.0 came out in a new one, which names its predecessor and gives a release date. File health 10, Config, template and card agree on the architecture and the 16K positions. 17 + 20 + 20 + 20 + 5 + 10 = 92.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (12 items). What it covers is at https://www.anchorterminal.com/fixes/granite-speech-5-0-2b.md (JSON https://www.anchorterminal.com/fixes/granite-speech-5-0-2b.json).

It has no stated terms or uptime, and a stricter reading gives 0\n- Ollama is credited on IBM's own entry in Ollama's registry (ibm/granite5-speech), not a library entry Ollama made\n- Agent guidance is 10 for the fallback behaviour and the Granite Guardian recommendation. The Granite 4.2 listings got 5 for the general section alone\n- Version policy would be 10 if the 4.1 card carries a dated note. It wasn't read\n- Capability is pending. The card cites the Open ASR and FFASR leaderboards, which an independent read would settle\n- unchecked on 10 November: the blog post, the papers, the ONNX repository, the litert-community conversion, LM Studio's catalogue, and IBM's watsonx model list\n\n### Sources\n\n- model card: \u003chttps://huggingface.co/ibm-granite/granite-speech-5.0-2b\u003e (seen 2026-11-10)\n- gating, dates, parameter count, downloads, likes, file list and hashes: \u003chttps://huggingface.co/api/models/ibm-granite/granite-speech-5.0-2b?blobs=true\u003e (seen 2026-11-10)\n- IBM's GGUF repository: files and sizes: \u003chttps://huggingface.co/api/models/ibm-granite/granite-speech-5.0-2b-GGUF?blobs=true\u003e (seen 2026-11-10)\n- inference providers, none mapped: \u003chttps://huggingface.co/api/models/ibm-granite/granite-speech-5.0-2b?expand[]=inferenceProviderMapping\u003e (seen 2026-11-10)\n- commit history: \u003chttps://huggingface.co/api/models/ibm-granite/granite-speech-5.0-2b/commits/main\u003e (seen 2026-11-10)\n- architecture and positions: \u003chttps://huggingface.co/ibm-granite/granite-speech-5.0-2b/raw/main/config.json\u003e (seen 2026-11-10)\n- chat template: \u003chttps://huggingface.co/ibm-granite/granite-speech-5.0-2b/raw/main/chat_template.jinja\u003e (seen 2026-11-10)\n- discussions, replies counted by script from authors, dates and member flags: \u003chttps://huggingface.co/api/models/ibm-granite/granite-speech-5.0-2b/discussions\u003e (seen 2026-11-10)\n- Ollama's page for ibm/granite5-speech: \u003chttps://ollama.com/ibm/granite5-speech\u003e (seen 2026-11-10)\n- vLLM v0.33.0, granite_speech.py: \u003chttps://raw.githubusercontent.com/vllm-project/vllm/v0.33.0/vllm/model_executor/models/granite_speech.py\u003e (seen 2026-11-10)\n- Transformers v5.22.2 granite_speech: \u003chttps://github.com/huggingface/transformers/tree/v5.22.2/src/transformers/models/granite_speech\u003e (seen 2026-11-10)\n- llama.cpp b12242, the converter (conversion/granite.py) and the audio front end (tools/mtmd), shallow clone: \u003chttps://github.com/ggml-org/llama.cpp/tree/b12242/tools/mtmd\u003e (seen 2026-11-10)\n- IBM's security.txt, as read for the Granite 4.2 3B listing: \u003chttps://www.ibm.com/.well-known/security.txt\u003e (seen 2026-11-10)\n- our Granite 4.2 listings, for company facts: \u003chttps://www.anchorterminal.com/tools/granite-4-2-8b\u003e (seen 2026-11-10)\n\n## Score history\n\nEvery move of a score since the listing was graded, newest first, with its cause.

Not legal advice.\n\n**Terms of service**. Nothing is hosted by the vendor, so there are no terms of service to read. The Apache-2.0 licence stands in and the check scores in full.\n\n\n**Privacy policy**. Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored.\n\n\n## Humans behind the project (researched 2026-11-10 from public pages, not part of the grade)\n\n### Key people\n\n- Charles Ranlett Flint, Co-founder, IBM (as Computing-Tabulating-Recording Company)\n- Herman Hollerith, Co-founder, IBM (as Computing-Tabulating-Recording Company)\n- George Winthrop Fairchild, Co-founder, IBM (as Computing-Tabulating-Recording Company)\n- Arvind Krishna, Chairman, President and Chief Executive Officer\n- Jay Gambetta, Director of IBM Research\n- Note: IBM is a listed company whose founders, per Wikipedia, are those of its 1911 predecessor, the Computing-Tabulating-Recording Company. IBM's senior leadership page, read on 28 October 2026, names Arvind Krishna as Chairman, President and Chief Executive Officer and Jay Gambetta as Director of IBM Research, the lab that announces and publishes the Granite models (https://research.ibm.com/blog/introducing-granite-4-2). IBM names no chief technology officer there, and the Granite pages name no single product lead. The paper authors on two listings (Parul Awasthy on granite-embedding-small-english-r2, Inkit Padhi on granite-guardian) stay as they are.\n- IBM: LinkedIn https://www.linkedin.com/company/ibm X https://x.com/ibm GitHub https://github.com/ibm-granite\n\n### Ownership and investors\n\n- Ownership: Public company (NYSE: IBM)\n\n### Getting support\n\n- Help: https://huggingface.co/ibm-granite/granite-speech-5.0-2b/discussions\n- Help: https://github.com/ibm-granite/granite-4.2-language-models/issues\n- Community (Model community discussions): https://huggingface.co/ibm-granite/granite-speech-5.0-2b/discussions\n- Sources: https://huggingface.co/ibm-granite/granite-4.2-3b, https://huggingface.co/ibm-granite/granite-4.2-3b/discussions, https://en.wikipedia.org/wiki/IBM, https://en.wikipedia.org/wiki/Charles_Ranlett_Flint, https://en.wikipedia.org/wiki/Herman_Hollerith, https://en.wikipedia.org/wiki/George_W._Fairchild, https://www.ibm.com/granite, https://www.ibm.com/us-en\n\n## Probe metrics\n\nNot measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\nNo hosted version of these weights has a price on OpenRouter, so what a task costs is your own hardware and power.\n\n## Strengths\n\n- Apache 2.0, ungated, with a signed repository\n- Runs in llama.cpp, Ollama, vLLM and Transformers, each documented\n- IBM's own GGUF builds, about 3 GB at the precision it recommends\n- Training data listed with hours and sources\n- Keyword lists of up to 2,000 terms\n- Updated in the last week, and both questions on the repository answered\n\n## Weaknesses\n\n- About two minutes of audio per request, so long recordings must be split\n- Plain text out: no timestamps, segments or speaker labels\n- Six languages\n- Builds below Q8_0 lose accuracy on longer audio, by IBM's own account\n- No safety results\n- No cut-off for the training data\n\n\n\n## Before you call it (notes for agents)\n\n1. Split recordings into segments of up to about two minutes of 16 kHz mono audio before sending them\n2. Use the card's prompt for the task word for word, such as `transcribe the speech with proper punctuation and capitalization.`\n3. Use Q8_0. IBM says lower precisions lose accuracy on audio over about a minute\n4. To spell names and jargon right, add a keyword list to the prompt, up to 2,000 terms\n5. With vLLM, serve with `--max-model-len 2048`, as the card does\n6. An unknown prompt falls back to transcription, so check that the output is the task you asked for\n\n## Get started\n\nInstall:\n\n```bash\nbrew install llama.cpp\nllama-cli -st -hf ibm-granite/granite-speech-5.0-2b-GGUF:Q8_0 --audio audio.wav -p \"transcribe the speech with proper punctuation and capitalization.\"\n# or: ollama run ibm/granite5-speech:2b, or vllm serve ibm-granite/granite-speech-5.0-2b --max-model-len 2048\n```\n\nFirst request:\n\n```bash\n# vLLM and llama-server both serve an OpenAI-compatible chat API. Send 16 kHz mono audio of up to about\n# two minutes as base64 in the message, with one of the card's task prompts as the text\n```\n\n## Similar tools\n\nRanked by shared capabilities, then score.
