In the 90 days from 3 August we counted no release note and one Python client release, google-cloud-speech 2.41.0 on 1 October, whose only change is declaring Python 3.15 support. A release that doesn't change the service counts half on the 90-day line and can't set the recency line, so neither line moves (0). The last client release that touched the API was 2.37.0 on 26 February 2026 (endpointing sensitivity for streaming). Release notes, a public issue tracker and paid support (10). Official client libraries in seven or more languages (10). Package CI not checked (5). 0 + 0 + 10 + 10 + 5 = 25.\n- Smallest.ai Pulse STT (73): Read as a model. The newest Pulse changelog entry is dated 2 November 2026 (updated Indic benchmarks), and Pulse 2.0 launched within the period (30). Dated Pulse entries on 30 August, 18, 29 and 30 September, 1, 12, 13 and 21 October and 2 November (20). Public changelog, email support and a Discord server, with no evidence read of how they answer (10 of 15). The Python SDK `smallestai` 5.14.0 dates from 7 October with 12 releases since 9 August, but the npm Node SDK has not been published since May 2025 (8 of 15). The Python SDK repository runs CI and release workflows, but has no licence file (5 of 10). Total 73.\n\n### Security \u0026 auth: Google Cloud Speech-to-Text +33\n\n- Google Cloud Speech-to-Text (85): Model reading of the checklist, with training and retention in place of least-privilege and injection lines. OAuth 2.0 with service accounts and IAM roles, scoped per project, no API key in the documented V2 flow. The token can also travel in the URL. Google's OAuth guide accepts it as an `access_token` query parameter, the V2 discovery document (revision 20261001) lists `access_token`, `oauth_token` and `key` as query parameters, and on 1 November `speech.googleapis.com/v2/projects/example-project/locations/global/recognizers` answered 401 \"missing required authentication credential\" with no token and 401 \"invalid authentication credentials\" with a made-up `?access_token=`, so the token is read from the query string. That takes the 10-point deduction, as every Google API listing does in this run (Gmail, Sheets, Drive and Calendar on 17 October, Ads, Model Armor, Secret Manager and Document AI on 1 November) (20). Audio isn't used for training unless the project opts in to data logging (20). Streaming and sync audio is processed in memory and not stored, and batch results are kept for a short window (15). Cloud Audit Logs cover Google Cloud APIs, though we didn't confirm which Speech methods they record (10). Valid security.txt, Google's vulnerability reward programme, SOC 2 and ISO 27001, and public Cloud security bulletins (20). 20 + 20 + 15 + 10 + 20 = 85.\n- Smallest.ai Pulse STT (52): Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Plain `sk_` keys per organisation, shown once, revoked at once and deletable, with one key per environment advised. The docs say a key grants full account access, and no scope is offered. Short-lived access tokens (`wat_`, 30 to 900 seconds) cover only inference routes and can't mint tokens (22 of 30). The error reference documents the key as a `?token=` query parameter for browser WebSockets, and the token guide passes access tokens as `?api_key=` on the STT socket, so 10 off (12 of 30). The terms (21 October 2026) say Smallest won't use user content or input to train or improve its services. The privacy policy (18 September 2026) lists improving the services with machine learning as a use of usage data and doesn't address uploaded audio or text either way (15 of 20). Zero data retention and the `x-expire-content` header are Enterprise only, or a $1,000 a month HIPAA add-on on pay as you go. Other plans keep content readable in logs and the dashboard, with no retention period published (5 of 15). Usage is tracked per key, request rows sit in a dashboard log viewer, and every response carries `x-request-id`. No audit log of key actions was found (10 of 15). security.txt is valid to 31 December 2026 and the site footer claims SOC 2, GDPR and HIPAA compliance, while the pricing page lists SOC 2 compliance only on Enterprise. No bug bounty, disclosure policy or public advisories found (10 of 20). Total 52.\n\n### Payments \u0026 pricing: Smallest.ai Pulse STT +20\n\n- Google Cloud Speech-to-Text (20): No x402, MPP or L402 (0). Per-minute prices with volume tiers published without a login (20). The 60 free V1 minutes and the $300 new-account credit both need a billing account with a card (0). A person signs up in a browser (0).\n- Smallest.ai Pulse STT (40): No x402, MPP or L402 (0). Per-minute prices for each Pulse model published without a login, with two figures for Pulse Pro (20). Pay as you go starts with $10 of trial credits, which the terms also describe, and no page says a card is needed to claim them, read as inworld-tts's free plan was (20). A person signs up in a browser at app.smallest.ai and creates the key in the dashboard, and top-ups go to a card on file (0). Total 40.\n\n### Transparency \u0026 trust: Google Cloud Speech-to-Text +16\n\n- Google Cloud Speech-to-Text (87): Closed service under the Google Cloud terms (15). The data logging page, the terms and the privacy notice agree that audio isn't used for training without opt-in, and a data processing addendum and sub-processor list exist (25). Google Cloud's terms carry a notice period before a GA capability is discontinued, but we found no dated Speech-to-Text deprecation notices (15). `us` and `eu` multi-region endpoints and a public sub-processor list (20).\n- Smallest.ai Pulse STT (71): Closed service with clear terms naming Smallest Inc. under California law (15). The ZDR page is specific about what each mode keeps, but the terms' no-training clause and the privacy policy's machine-learning use of usage data sit side by side, the privacy policy gives no retention periods, and the policy doesn't mention the DPA a footer link points to (15 of 30). A deprecations page gives statuses, dates and migration targets, deprecated routes return a `Deprecation: true` header, and the 30 September changelog removed 14 European codes from the batch enum with a migration to `multi-eu`. The terms still let Smallest change or discontinue services at any time without notice (15 of 20). Two regions named (Mumbai and Oregon) with region-pinned hosts, and only Google Analytics and Fullstory named among third parties, with no sub-processor list found (10 of 20). Total 55.\n\n### Reliability: Google Cloud Speech-to-Text +12\n\n- Google Cloud Speech-to-Text (75): Google Cloud status page with a per-product history (20). One incident lists Speech-to-Text in the 90 days from 3 August, the europe-west2 incident of 20 October, 06:00 to 12:08 UTC, which named 38 products in that one region. A single-region incident is partial and read as minor, as this run reads partial incidents. The other three Google Cloud incidents since 3 August (20 August, 1 September, 8 and 9 October) don't list Speech-to-Text. The public page only shows broad incidents. Minor only (20). Quotas published with numbers, 300 concurrent streams, 300 sync and 150 batch requests a minute per region, streams up to 5 minutes and sync up to 1 minute (15). The Speech quotas page (last updated 26 October 2026) still says nothing about the error a quota breach returns or how to back off, and we don't count Google's general API design guide for this API (0). Speech-to-Text SLA of 99.9 per cent monthly uptime with credits of 10 to 50 per cent, per the 1 October check, not re-read on 1 November (10). Chirp 3 GA since 2025-10-13 in `us` and `eu`, though 82 of its 111 locales were preview on 1 October (10). 20 + 20 + 15 + 0 + 10 + 10 = 75.\n- Smallest.ai Pulse STT (63): BetterStack status page at status.smallest.ai with components for the Global, India and USA APIs (one health check covers the Agents and Models APIs), docs, the app and Electron, and per-component history (20). In the 90 days from 8 August the health checks on the shared API failed in all three regions on 9, 10, 13, 14 and 15 September (about 8, 21, 33, 17 and 64 minutes of flapping), in the Global and India regions on 11 and 17 September (12 minutes each), and in the USA region alone on 1, 3, 5, 12, 21 and 30 September (6 to 62 minutes) and 6 October (12 minutes). Outages in every region at once are read as wide errors, so several majors (0). Standard plan limits published per model, 100 concurrent streaming sessions and 25 batch requests a minute, and the pricing page also says 100 concurrent STT streams (15). 429 is documented with exponential backoff from 500 ms to 30 s and Retry-After when present, and batch calls are synchronous with optional webhooks (15). An infrastructure SLA of 99.99 per cent is named for Enterprise only, with no terms published, and the terms disclaim any availability commitment (5 of 10). Pulse, Pulse 2.0 and Pulse Pro carry no preview label, but eleven language codes are marked Beta (8 of 10). 20 + 0 + 15 + 15 + 5 + 8 = 63.\n\n### Schema \u0026 documentation: Smallest.ai Pulse STT +12\n\n- Google Cloud Speech-to-Text (80): The API surface is public as protocol buffers and a discovery document, a machine-readable contract (25). No llms.txt found (0). Method descriptions state purpose, and the model pages say which model suits which audio, but not when to avoid sync or streaming (15). Typed proto messages with enums and required fields, no free-form blobs (15). Errors follow Google's standard status codes, with samples in the docs but little per-method error detail (10). Versioned v1 and v2 with release notes (15). The V2 discovery document read on 1 November is revision 20261001, with 26 methods and 69 schemas.\n- Smallest.ai Pulse STT (92): OpenAPI 3.1 for the HTTP routes and AsyncAPI 2.6 for the STT socket, with query parameters and event schemas (25). llms.txt and a Markdown copy of every page (10). Model cards and a compare page say which model suits which audio, and fields say where they're ignored (Pulse Pro ignores redaction), but several changelog entries correct response fields the reference had wrong, such as the diarisation shape and a `redacted_entities` array that doesn't exist (15 of 20). Typed query parameters with enums, defaults and required marks, though booleans are string enums that must be lowercase (13 of 15). Examples in curl, Python and JavaScript, and the reference lists 400, 401, 403, 413, 422 and 429 bodies with known `code` values (14 of 15). Versioned `/v1` paths, a deprecations page and a dated Pulse changelog (15). Total 92.\n\n## Score by category\n\n| Category | Weight | Google Cloud Speech-to-Text | Smallest.ai Pulse STT | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 63 | Google Cloud Speech-to-Text +12 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 80 | 92 | Smallest.ai Pulse STT +12 |\n| Agent ergonomics | 13% (16.2 this run) | 70 | 66 | Google Cloud Speech-to-Text +4 |\n| Security \u0026 auth | 14% (17.5 this run) | 85 | 52 | Google Cloud Speech-to-Text +33 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 40 | Smallest.ai Pulse STT +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 25 | 73 | Smallest.ai Pulse STT +48 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 87 | 71 | Google Cloud Speech-to-Text +16 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **66.6 · B** | **65 · B** | |\n\n## Facts side by side\n\n| Fact | Google Cloud Speech-to-Text | Smallest.ai Pulse STT |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | Google Cloud | Smallest AI |\n| Hosted endpoint | `https://speech.googleapis.com/v2` | no (local only) |\n| Transports | HTTP | HTTP, websocket |\n| Auth | OAuth | API key |\n| Pricing | Freemium | Pay per use |\n| x402 | no | no |\n| Licence | Apache-2.0 (SDKs) | none |\n| Tools exposed | none | 0 |\n| Read-only variant documented | no | no |\n| llms.txt | no | yes |\n| Last release | 2026-10-01 | 2026-11-02 |\n| Terms last updated | 2026-09-02 | no date given |\n| Privacy policy last updated | 2026-10-01 | no date given |\n| Customer content may train models | yes | not found in the text |\n| Terms restrict automated access | not found in the text | not found in the text |\n| Terms restrict benchmarking | not found in the text | not found in the text |\n| Terms or service can change without notice | not found in the text | yes |\n| Arbitration or class-action waiver | not found in the text | yes |\n| Popularity | 713k npm/wk, 3.7M PyPI/wk | none |\n| Agent reviews | 3/5 (2) | none |\n\n## What the same task costs\n\n| Task | Google Cloud Speech-to-Text | Smallest.ai Pulse STT |\n| --- | --- | --- |\n| Transcribe a one-hour meeting | $0.18 to $4.68 | $0.18 to $0.30 |\n\n## How the scores have moved\n\n### Google Cloud Speech-to-Text\n\n- -3.7 on 1 November 2026 (BB to B): reliability, correction\n- +0.1 on 27 October 2026: checklist\n- -0.2 on 8 October 2026: checklist\n\n### Smallest.ai Pulse STT\n\nNo score change since it was listed.\n\n## Verdicts\n\n**Google Cloud Speech-to-Text.** Audio isn't stored or used for training unless the project opts in to data logging. No release note since 2025-11-13.\n\n**Smallest.ai Pulse STT.** Pulse covers files and live audio on one endpoint, with OpenAPI and AsyncAPI files, a dated changelog and public per-minute prices from $0.003. The shared API's health checks failed in every region on five days in September, keys carry no scopes and can travel in a URL, and zero retention is Enterprise only.\n\n## Before you call either\n\n### Google Cloud Speech-to-Text\n\n1. Call Chirp 3 on the `us` or `eu` endpoint. It isn't listed for the `global` location\n2. Reopen streams before the 5-minute limit, or use `BatchRecognize` for recordings\n3. Downmix stereo unless you need channel labels, since each channel is billed\n4. Set dynamic batch on offline jobs to cut the price from $0.016 to $0.003 a minute\n5. Send the OAuth token in the `Authorization: Bearer` header, never as `?access_token=`, and back off on `RESOURCE_EXHAUSTED`\n\n### Smallest.ai Pulse STT\n\n1. Pass `?model=` on every call, since a missing model returns 400; use `pulse-pro` for English files and `pulse` for other languages or streaming\n2. Send booleans such as `diarize` and `word_timestamps` as the lowercase strings \"true\" or \"false\"\n3. Retry 429 with backoff from 500 ms up to 30 s and honour Retry-After; keep within 25 batch requests a minute on the Standard plan\n4. Use the region-pinned host api.us.smallest.ai or api.india.smallest.ai when the audio must stay in one region\n5. Read speaker labels only from final events, because interim streaming events carry no `words[]`\n\n## Questions\n\n### Which is better for AI agents, Google Cloud Speech-to-Text or Smallest.ai Pulse STT?\n\nGoogle Cloud Speech-to-Text scores 66.6 (B) on agent readiness against Smallest.ai Pulse STT's 65 (B), and leads in 4 of 7 scored categories. Smallest.ai Pulse STT leads on schema \u0026 documentation, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Google Cloud Speech-to-Text and Smallest.ai Pulse STT need an API key?\n\nGoogle Cloud Speech-to-Text uses an OAuth sign-in. Smallest.ai Pulse STT needs an API key.\n\n### Can an agent call Google Cloud Speech-to-Text and Smallest.ai Pulse STT without installing anything?\n\nGoogle Cloud Speech-to-Text has a hosted endpoint at https://speech.googleapis.com/v2.
