## Score breakdown (methodology v0.7, October 2026 research run)

Assessed 2026-11-06 from public evidence against the published checklist (https://www.anchorterminal.com/benchmark/#checklist). 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.

| Category | Weight | This run | Score (0–100) | Points |
| --- | --- | --- | --- | --- |
| Reliability | 16% | 20 | 40 | 8.0 |
| Performance | 10% | pending | pending | n/a |
| Schema & documentation | 13% | 16.2 | 55 | 8.9 |
| Agent ergonomics | 13% | 16.2 | 66 | 10.7 |
| Security & auth | 14% | 17.5 | 68 | 11.9 |
| Payments & pricing | 10% | 12.5 | 40 | 5.0 |
| Task success | 10% | pending | pending | n/a |
| Maintenance & community | 7% | 8.8 | 33 | 2.9 |
| Transparency & trust (editorial 65, provenance 94) | 7% | 8.8 | 80 | 7.0 |
| Negative events | up to −15 | up to −15 | none recorded | 0 |
| **Total** | | | | **54.5 → C** |

### Why each score

- 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.
- 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.
- Schema & 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.
- 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.
- Security & 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.
- Payments & 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.
- 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.
- Maintenance & 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.
- Transparency & 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.

Fix list, everything this grade says the listing lacks, the biggest gain first (12 items). What it covers is at https://www.anchorterminal.com/fixes/ibm-watson-stt.md (JSON https://www.anchorterminal.com/fixes/ibm-watson-stt.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{"listing": "ibm-watson-stt", "plan": "read"}`, free while the beta runs

### What we couldn't check

- unchecked: IBM Cloud status history, because the page is drawn by script
- unchecked: the service's SLA and certifications
- unchecked: whether IBM Cloud signup asks for a card for a Lite plan

## Who's behind it (provenance 94/100, checked 2026-11-06)

| Check | Finding | Points |
| --- | --- | --- |
| Legal entity named | International Business Machines Corporation | 20/20 |
| Domain age | ibm.com, registered 1986-03-19 (40 years) | 15/15 |

The endpoints are on watson.cloud.ibm.com, under ibm.com.

cloud.ibm.com/robots.txt disallows only /docs/search?q= and sets Content-Signal ai-train=yes, search=yes, ai-input=yes.

www.ibm.com/.well-known/security.txt names IBM PSIRT, HackerOne and psirt@us.ibm.com and expires on 6 December 2026.

cloud.ibm.com/status returns a page drawn by script, so its incident history wasn't read.

The IBM Cloud terms page was found but its text wasn't read, so no clause is quoted.

RDAP gives ibm.com a registration date of 19 March 1986.

## Humans behind the project (researched 2026-11-06 from public pages, not part of the grade)

### Key people

- Charles Ranlett Flint, Co-founder, IBM (as Computing-Tabulating-Recording Company)
- Herman Hollerith, Co-founder, IBM (as Computing-Tabulating-Recording Company)
- George Winthrop Fairchild, Co-founder, IBM (as Computing-Tabulating-Recording Company)
- Arvind Krishna, Chairman, President and Chief Executive Officer
- Jay Gambetta, Director of IBM Research
- Inkit Padhi, First author, Granite Guardian paper (IBM Research)
- Note: Copied on 6 November 2026 from the granite-guardian listing's humans file (checked 28 October 2026), since the company is the same. 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.

Not 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.

## Prices

| Item | Price | Unit | Note |
| --- | --- | --- | --- |
| Plus plan, first 999,999 minutes a month | $0.02 | per minute of audio |  |
| Plus plan, from 1,000,000 minutes a month | $0.01 | per minute of audio |  |

Across all listings: https://www.anchorterminal.com/prices/index.md

## What a task costs (from the prices above)

| Task | Cost | At |
| --- | --- | --- |
| 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 |

The 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.

## Strengths

- Sync, async with callbacks and WebSocket streaming on one service
- 500 free minutes a month on Lite and $0.02 a minute on Plus
- Custom language and acoustic models on paid plans
- Dated deprecation of previous-generation models with over a year of notice
- `DELETE /v1/user_data` removes data by customer ID

## Weaknesses

- No public OpenAPI file or llms.txt
- The WebSocket interface takes the IAM token as a URL query parameter
- Requests are logged by default to improve the service unless the account or request opts out
- The status page is drawn by script and no SLA was read
- No release note since 29 June 2026



## Before you call it (notes for agents)

1. Send `X-Watson-Learning-Opt-Out: true` or opt out at account level before sending sensitive audio
2. Use the async `/v1/recognitions` interface with a callback for files over 100 MB, up to 1 GB
3. Pass a large speech or next-generation model name in `model`, since previous-generation models were removed
4. Tag requests with `X-Watson-Metadata: customer_id=...` so the data can be deleted later
5. Keep within 100 concurrent requests on Plus across HTTP and WebSocket

## Connect

Install:

```bash
pip install ibm-watson
```

## Verify this listing

For the vendor. The badge or a plain link to this page verifies the listing, from a page on ibm.com or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "ibm-watson-stt", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it. What we check: https://www.anchorterminal.com/builders/index.md#verify
