MiniMax Speech-to-Text vs Rev AI Speech-to-Text API

MiniMax Speech-to-Text 6

Read as a model. No dated release or change of asr-1.0 was found on the model or API release notes or the status page (0). No dated ASR entries in the last 90 days (0). Support by email and Discord, not tested (6 of 15). No official SDK, and the MCP servers have no transcription tool (0 of 15). No package to judge (0 of 10). Total 6.

Rev AI Speech-to-Text API 40

Read on the model lines the other speech-to-text model listings use (recency 30, dated releases 10, notice 10, support 15, issues 10, SDKs 15, health 10), where the 1 October note used the tool lines. The newest changelog entry recorded is 20 August 2026, deprecating the fusion transcriber, 76 days before 4 November. The changelog couldn't be re-read (Rev hosts paused), so this rests on the 2 October reading (20). Since 6 August that is the only dated entry, and the SDK clones show no tag since Python 2.21.0 (27 November 2024) and Node 3.8.6 (25 October 2024), and no commit since 12 May 2026, so fewer than three (0). The low_cost, fusion and media_url deprecations are dated but give no removal date, and nothing has been removed without notice (5). Public changelog and an email support channel (10). SDK issue replies unread, github.com answers 403 (0). The published SDKs aren't current. npm's latest Node SDK was 3.8.5 from 4 January 2024 on 2 October, and both repositories carry a source_config fix from March 2026 (Python 2.22.0, Node 3.9.0 in source) that is in no tag. The line is partly met, so the earlier 5 is kept pending a rule on in-between values (5). Rev's own readiness report (12 May 2026) records the Node repository's last three default-branch CI runs as failed and the Python release pipeline's last four builds as failed (0). 20+0+5+10+0+5+0 = 40.

MiniMax Speech-to-Text 47

Atlassian Statuspage at status.minimax.io with component history, but its components are LLM, Text-to-Speech and Video Generation, with none for speech to text (10 of 20). With no component, the history holds no record for transcription (5). Limits published with numbers, 2 concurrent connections and 30,000 audio seconds a minute (15). 429 is documented as rate_limit_error, and the general error code page says to retry later, with no backoff figures or Retry-After (7 of 15). No SLA in the terms or docs (0). asr-1.0 is called the current public model with no beta label (10). 10 + 5 + 15 + 7 + 0 + 10 = 47.

Rev AI Speech-to-Text API 75

Statuspage at status.rev.ai with component history (20), per the 1 October check, not re-read on 4 November, because the Rev terms (updated 14 October 2026) bar using any automated system to extract content from Rev's web sites, so every Rev host is paused for this run. The history feed read on 1 October showed no incident since 13 May 2026, and the page has posted eight incidents since September 2022. The window from 6 August is held at what that reading supports, with 2 October to 4 November unread (30). Limits published with numbers, 10,000 async submissions and 500 processing jobs per 10 minutes and 10 concurrent streams (15). No 429 handling, Retry-After or backoff guidance in the async reference, the get-started page or the changelog (0). No SLA found, and the pricing page names none (0). Async and streaming are GA (10). All per the 1 and 2 October checks. 20+30+15+0+0+10 = 75.

MiniMax Speech-to-Text 70

API reading of the checklist. The default json returns only text, duration and a trace ID, with segments and subtitles opt-in (22 of 25). No lists to page. response_format and language are the output controls (12 of 20). Typed error envelopes with the real HTTP status, an error type and request_id, and 402 for an empty balance (18 of 20). Calls are synchronous with no idempotency key (10 of 20). Two fields, a model and a file. No official SDK, and MiniMax's MCP servers don't cover transcription (8 of 15). Total 70.

Rev AI Speech-to-Text API 52

API reading of the checklist, on the docs as read on 1 and 2 October (not re-read on 4 November, Rev hosts paused). Transcripts come back as JSON or plain text by Accept header, and captions as SRT or VTT (20). GET /jobs pages with limit and starting_after (20). Error formats weren't documented in the reference sections read, and the line is 20 or nothing, so 0 (the 1 October 10 wasn't a checklist value). No idempotency key. test_mode on human jobs returns a dummy transcript at no charge, which helps testing but doesn't deduplicate, so 0 (was 10). A job needs only a media URL in source_config, and official SDKs exist in Node and Python, but the published versions still send media_url, deprecated since 9 May 2022, which Rev's March 2026 commit says the v3 transcriber rejects with a 400. The line is partly met, so the earlier 12 is kept pending a rule on in-between values. 20+20+0+0+12 = 52.

MiniMax Speech-to-Text 33

Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Plain API keys from the console with no scopes found, and the docs say publicly leaked keys may be disabled, as on minimax-voice-cloning (20 of 30). The terms (effective 30 March 2026), as read for minimax-voice-cloning on 4 November, let MiniMax use input and generated content to operate, maintain, develop and improve its services, with no opt-out found, and the privacy policy rules out only training to profile or target consumers (5 of 20). No retention period for uploaded audio or transcripts was found (3 of 15). Each response carries a trace ID, with no audit log found (5 of 15). No security.txt, disclosure policy, bug bounty or certification found, as on the other MiniMax listings (0 of 20). Total 33.

Rev AI Speech-to-Text API 40

Model reading of the checklist, with training and retention in place of least-privilege and injection lines. Bearer access tokens, generated and replaced from the account page, with no scopes found (20). The streaming WebSocket takes that long-lived token as an access_token query parameter, a documented secret in a URL (minus 10). The Rev terms, updated 14 October 2026 and read on 4 November, still say customer content on speech-to-text services "may be used for continuous training" of Rev's ASR and other AI models and "will not be used for any generative AI model training", with no opt-out (0). Jobs and media are deleted after 30 days, sooner with delete_after_seconds, an account setting or a delete call. Streaming retention isn't stated (10). Jobs are listed per account, no audit log found (10). Rev's security page names SOC 2 Type II and links a SOC 3 report, plus PCI, HIPAA on the enterprise tier and CJIS. No security.txt, disclosure policy or bug bounty found (10 of 20). Docs and security page per the 1 and 2 October checks. 10+0+10+10+10 = 40.

MiniMax Speech-to-Text 63

Closed API with clear terms under Singapore law naming Nanonoble Pte. Ltd., as on the other MiniMax listings (15 of 30). The terms and privacy policy agree that inputs may be used to improve services and that data sits in a United States data centre, with no retention period for audio (8 of 30). No deprecation notice or policy touches the ASR API (10 of 20, for the dated notices elsewhere on the API release notes). Data location stated as the United States and an EU representative named, with third parties only by category (10 of 20). Total 43.

Rev AI Speech-to-Text API 69

Closed service under the Rev.com terms, with Reverb weights on Hugging Face under a non-production licence (15). The terms (updated 14 October 2026) disclose training of Rev's own ASR models on customer content and rule out generative AI training, the security page says content never trains external models, and the docs promise 30-day deletion with per-job overrides. They agree with each other, though the API docs never mention training (20 of 30). Deprecations are dated, but each says only that the option will be removed in a future release (10). EU deployment in Frankfurt documented, no sub-processor list found (10). Security page and docs per the 1 and 2 October checks. 15+20+10+10 = 55.
