Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 40 | 8.0 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 55 | 8.9 |\n| Agent ergonomics | 13% | 16.2 | 66 | 10.7 |\n| Security \u0026 auth | 14% | 17.5 | 68 | 11.9 |\n| Payments \u0026 pricing | 10% | 12.5 | 40 | 5.0 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 33 | 2.9 |\n| Transparency \u0026 trust (editorial 65, provenance 94) | 7% | 8.8 | 80 | 7.0 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **54.5 → C** |\n\n### Why each score\n\n- Reliability 40 (checked 2026-11-06): IBM Cloud has a status page at cloud.ibm.com/status, but it is drawn by script and showed no components or history to our reader, read as gemini-live's script-shell page was (10 of 20, and 5 for no readable history). Plus allows up to 100 concurrent transcription requests across WebSocket and HTTP (15). No 429 or backoff guidance was found in the API reference or the docs repository (0). No SLA was read for the service (0, unchecked). Next-generation and large speech models are GA, language by language (10). 10 + 5 + 15 + 0 + 0 + 10 = 40.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 55 (checked 2026-11-06): No public OpenAPI or other machine-readable definition was found (0). No llms.txt (0). The reference says which parameters each model family supports and the docs cover each feature (15 of 20). Typed parameters with defaults, ranges and enums (13 of 15). curl and SDK examples on every method, and errors with `error`, `code`, `code_description` and `warnings`, with invalid arguments reported as warnings (12 of 15). Versioned `/v1` paths and dated release notes back to 2015 (15). Total 55.\n- Agent ergonomics 66 (checked 2026-11-06): API reading of the checklist. Timestamps, word confidence, alternatives and speaker labels are opt-in (15 of 25). Async jobs and custom models list, and async results can go to a callback URL (12 of 20). Structured errors and warnings an agent can act on (15 of 20). Async jobs take a `user_token`, results have a TTL, and jobs can be deleted, with no idempotency key (12 of 20). Most parameters are optional. Official SDKs including Python, Node and Swift, though the Python and Node SDKs last released in January 2026 (12 of 15). Total 66.\n- Security \u0026 auth 68 (checked 2026-11-06): Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. IAM API keys per instance with Reader, Writer and Manager roles and short-lived bearer tokens (30). The WebSocket interface takes the token as an `access_token` query parameter, so 10 off (20 of 30). Request and response data are logged by default to improve the service, and any account can opt out per account or per request (10 of 20). Async results expire after a week by default (`results_ttl` shortens it), a delete method exists, and `DELETE /v1/user_data` removes data by customer ID (10 of 15). Activity Tracker events record changes to the service's state (10 of 15). Valid security.txt to 6 December 2026, PSIRT and HackerOne, HIPAA readiness on Premium. Certifications weren't read (18 of 20). Total 68.\n- Payments \u0026 pricing 40 (checked 2026-11-06): No x402, MPP or L402 (0). Per-minute Plus prices published in the docs without a login (20). The Lite plan gives 500 free minutes a month, and no page read says a card is needed (20). A person creates an IBM Cloud account and service instance in a browser (0). Total 40.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 33 (checked 2026-11-06): Read as a model. The newest release note is 29 June 2026 (`parameter_set` for large speech models), 130 days ago (10). No dated entries in the 90 days from 8 August (0). Release notes, IBM support and a public docs repository last changed 30 June 2026 (8 of 15). Official SDKs, `ibm-watson` 11.2.0 on PyPI (26 January 2026) and 12.2.0 on npm (January 2026) (10 of 15). CI not read (5 of 10). Total 33.\n- Transparency \u0026 trust 80 (checked 2026-11-06): Closed service under the IBM Cloud terms (15). The data security page states default logging for improvement with an opt-out, async retention, GDPR deletion by customer ID and plan-level separation, and they agree with each other. The DPA wasn't read (20 of 30). Previous-generation models carried a dated deprecation of 15 March 2022 and removal on 31 July 2023, and release notes say changes are compatible unless noted (18 of 20). Ten locations are named, with sub-processors not read (12 of 20). Total 65.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (12 items).

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://github.com/ibm-granite/granite-guardian/issues\n- Help: https://huggingface.co/ibm-granite/granite-guardian-4.1-8b/discussions\n- Community (Model community discussions): https://huggingface.co/ibm-granite/granite-guardian-4.1-8b/discussions\n- Sources: https://www.ibm.com/granite/docs/models/guardian, https://raw.githubusercontent.com/ibm-granite/granite-guardian/main/README.md, https://huggingface.co/ibm-granite/granite-guardian-4.1-8b/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## Live (updated 2026-11-07 16:00 UTC)\n\n- Vendor status page: not read, no machine-readable status found\n- npm `ibm-watson` 12.2.0\n- pypi `ibm-watson` 11.2.0, released 2026-01-26\n- security.txt: valid, expires 2026-12-07T00:00:00+00:00\n- Watching changelog \u003chttps://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-release-notes\u003e\n- Watching privacy \u003chttps://www.ibm.com/privacy\u003e\n- Watching terms \u003chttps://cloud.ibm.com/docs/overview?topic=overview-terms\u003e\n- Always current: https://www.anchorterminal.com/api/v1/live/ibm-watson-stt.json\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\n## Prices\n\n| Item | Price | Unit | Note |\n| --- | --- | --- | --- |\n| Plus plan, first 999,999 minutes a month | $0.02 | per minute of audio | |\n| Plus plan, from 1,000,000 minutes a month | $0.01 | per minute of audio | |\n\nAcross all listings: https://www.anchorterminal.com/prices/index.md\n\n## What a task costs (from the prices above)\n\n| Task | Cost | At |\n| --- | --- | --- |\n| Transcribe a one-hour meeting (60 minutes of recorded audio) | $0.60 to $1.20 | Plus plan, from 1,000,000 minutes a month to Plus plan, first 999,999 minutes a month |\n\nThe quantity times this listing's own price, from its cheapest item in that unit to its dearest. Plans, minimums and free allowances aren't counted.\n\n## Strengths\n\n- Sync, async with callbacks and WebSocket streaming on one service\n- 500 free minutes a month on Lite and $0.02 a minute on Plus\n- Custom language and acoustic models on paid plans\n- Dated deprecation of previous-generation models with over a year of notice\n- `DELETE /v1/user_data` removes data by customer ID\n\n## Weaknesses\n\n- No public OpenAPI file or llms.txt\n- The WebSocket interface takes the IAM token as a URL query parameter\n- Requests are logged by default to improve the service unless the account or request opts out\n- The status page is drawn by script and no SLA was read\n- No release note since 29 June 2026\n\n\n\n## Before you call it (notes for agents)\n\n1. Send `X-Watson-Learning-Opt-Out: true` or opt out at account level before sending sensitive audio\n2. Use the async `/v1/recognitions` interface with a callback for files over 100 MB, up to 1 GB\n3. Pass a large speech or next-generation model name in `model`, since previous-generation models were removed\n4. Tag requests with `X-Watson-Metadata: customer_id=...` so the data can be deleted later\n5. Keep within 100 concurrent requests on Plus across HTTP and WebSocket\n\n## Connect\n\nInstall:\n\n```bash\npip install ibm-watson\n```\n\n## Similar tools\n\nRanked by shared capabilities, then score.
