The newest dated change touching speech is the MCP servers' August update, `minimax-mcp-js` 0.0.18 on 21 August 2026, 77 days before 6 November, and Speech 2.8 dates from 23 January 2026 (20 of 30). No dated API entries in the last 90 days (0). Support by email and Discord, not tested (6 of 15). No official SDK for speech; the MCP servers expose `text_to_audio` and `list_voices` (8 of 15). The Python MCP server has tests and moved to version 2 of the MCP SDK in August, with no CI workflow (4 of 10). Total 38.\n- Rime TTS API + MCP (70): Read as a model, on the lines cartesia-tts and fish-audio-tts use for hosted speech models (recency 30, dated releases 10, deprecation notice 10, support 15, issues 10, SDKs 15, health 10). The changelog's newest entry is on-prem release `20261104` for Coda v2 and Mist v3 on 4 November 2026 (30). In the 90 days from 6 August, text-to-speech entries on 15 August, 25 August, 12 September, 25 September, 13 October, 28 October and 4 November, and SDK releases touching the TTS client (10). The terms of 29 October promise at least 30 days' notice before retiring a Model Version used on a paid plan, while Arcana's cloud retirement came 17 days after its 29 July notice (5 of 10, was 0). Public changelog with RSS and a support address (8 of 15). The SDK repository's issues couldn't be read (github.com answers 403), so the line stays absent (0). Official Rime SDKs in Python, Node.js, Go and Rust with TTS clients, newest python-v0.1.0-alpha.29 on 3 November, all alpha, read as rime-prism reads the same SDK (12 of 15, was 0). The SDK repository's checks workflow runs the tests with locked dependencies, results unread (5 of 10, was 0). 30+10+5+8+0+12+5 = 70.\n\n### Reliability: MiniMax Speech (T2A) +28\n\n- MiniMax Speech (T2A) (75): Atlassian Statuspage at status.minimax.io with a Text-to-Speech component (20). Its history, re-read on 6 November, shows three incidents in the 90 days from 8 August, all titled elevated errors and labelled major, 22 minutes on 28 September, 3 minutes on 16 October and 2 minutes on 19 October, and none in November. Elevated errors with no fuller scope are read as partial, as on minimax-api and minimax-voice-cloning, so minor only (20). T2A is limited to 60 requests a minute, with higher limits on audio subscriptions (15). Error codes 1002 and 2045 say to retry later and avoid sudden increases, with no Retry-After or backoff figures (10 of 15). No SLA (0). No beta or preview label on T2A (10). 20 + 20 + 15 + 10 + 0 + 10 = 75.\n- Rime TTS API + MCP (47): status.rime.ai now redirects to www.rimestat.us, an incident.io page with a Text-to-speech API component and history since 30 August 2026 (20, was 10). Its feed lists two incidents in the 90 days from 6 August, \"Text-to-speech APIs are partially degraded\" on 3 and 5 September, both partial. The window before 30 August can't be read, and this run gives no credit for an unread part of the window, so the line keeps its recorded award (5). The errors page says synthesis concurrency depends on the plan and points to the pricing page, which on 4 November lists the Free, Flex, Scale and Enterprise plans with no concurrency or rate figure, and the WebSocket connection limit isn't published. The Starter figure of 20 concurrent generations is gone (0, was 10). The errors page says to back off on 429 and retry the upgrade after a delay, marks 500 and 502 as retryable and warns that retries bill as new synthesis. Synthesis writes nothing, so safe-retry guidance without idempotency keys earns 12 in this run, as soniox-tts, fish-audio-tts and rime-prism (12, was 15). SLAs are an Enterprise item, none published (0). Coda and Mist v3 are GA (10). 20+5+0+12+0+10 = 47.\n\n### Security \u0026 auth: Rime TTS API + MCP +23\n\n- MiniMax Speech (T2A) (36): Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Plain API keys with no scopes found, and leaked keys may be disabled (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). The speech docs call every interface stateless, and no retention period for submitted text or generated audio was found (5 of 15). Responses carry `usage_characters` and a trace ID, with no audit log (6 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20). Total 36.\n- Rime TTS API + MCP (59): Model reading of the checklist, with training and retention in place of least-privilege and injection lines. One Bearer key per request, sent as a header on WebSockets too, with no scopes or short-lived tokens, so browser apps need a server bridge (20 of 30). The terms effective 29 October 2026 (section 6.3(b)) grant Rime a perpetual licence to train its models on Free Plan customer data, excluding voice recordings and audio with a natural person's voice, with no opt-out found. Paid plans aren't covered by that licence, and the privacy policy says customer data isn't used for training unless agreed (10, was 20). Only character counts are kept by default, and request retention for support is an off-by-default dashboard switch since 2026-08-25 (15). No per-call log found (0 of 15). SOC 2 Type II since May 2025, HIPAA since February 2024 with an audit in March 2026, and a formal vulnerability disclosure programme linked from the security page. No security.txt or bug bounty, the same reading as rime-prism (14 of 20, was 10). 20+10+15+0+14 = 59.\n\n### Schema \u0026 documentation: MiniMax Speech (T2A) +22\n\n- MiniMax Speech (T2A) (81): OpenAPI 3.1 for the sync and async routes and AsyncAPI files for the WebSocket and bidirectional sockets (25). llms.txt and a Markdown copy of every page (10). The text field says when to stream and how to mark pauses, and guides separate sync, WebSocket and async use (15 of 20). Enums for model and audio settings, with `model` and `text` required (13 of 15). Examples throughout and the shared table of error codes, but the OpenAPI file documents only a 200 response (10 of 15). Versioned `/v1` paths. The API release notes stop at 28 October 2025, and the last T2A entry is 23 September 2025 (8 of 15). Total 81.\n- Rime TTS API + MCP (59): No OpenAPI file (0). The Coda Protobuf quickstart says the `rime-api` package on PyPI carries `text_to_speech.proto` and `text_to_speech.asyncapi.yaml`, but pypi.org didn't resolve on 4 November, so the files weren't read and the line stays at 0 as never read. llms.txt with Markdown pages (10). The models page says which model suits what, and that a request without `modelId` goes to Mist v3 (15 of 20). Parameters are typed in reference tables (10 of 15). Examples on each endpoint and an errors page listing the messages for each status, as plain text (12 of 15). Dated changelog and versioned WebSocket paths (`/ws3`, `/ws2`), no API version header (12 of 15). 0+10+15+10+12+12 = 59.\n\n### Payments \u0026 pricing: Rime TTS API + MCP +20\n\n- MiniMax Speech (T2A) (20): No x402, MPP or L402 (0). Per-character prices for every speech model published without a login (20). No free allowance for synthesis is published (0). A person signs up in a browser and funds a balance (0). Total 20.\n- Rime TTS API + MCP (40): No x402, MPP or L402 (0). Per-minute prices published without a login, Mist v3 $0.030 and Coda v2 $0.050 a minute on Flex, $0.024 and $0.040 on Scale, metered by characters at about 1,000 a minute (20). Every account gets $50 of usage a month on the Free plan with no card (20). A person signs up in a browser (0). 0+20+20+0 = 40.\n\n### Transparency \u0026 trust: Rime TTS API + MCP +11\n\n- MiniMax Speech (T2A) (65): Closed API with clear terms under Singapore law naming Nanonoble Pte. Ltd., and MIT MCP servers (15 of 30). 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, as on minimax-voice-cloning (8 of 30). The API release notes carry a dated legacy notice of 20 June 2025 for the old text-to-voice API with service continuing, and older speech models stay accepted, with no written policy or notice period (15 of 20). Data location stated as the United States and an EU representative named, third parties only by category (10 of 20). Total 48.\n- Rime TTS API + MCP (76): Closed service with clear terms, effective 29 October 2026, and the SDK under MIT (15). The privacy page and the changelog agree on character counts only and optional retention off by default. The new terms' Free Plan training licence contradicts the security page's \"We never use customer text or audio to train our models\", which is charged once as the misleading-claim deduction, so the line holds (22 of 30). The terms promise at least 30 days' notice before a paid plan's Model Version is retired, and Arcana's retirement in August came with 17 days' notice before that policy, the reading rime-prism takes (15, was 10). A sub-processor list names 12 companies with their services, all in the United States, and the cloud runs in US West and US East plus VPC and on-prem (18, was 8). 15+22+15+18 = 70.\n\n## Score by category\n\n| Category | Weight | MiniMax Speech (T2A) | Rime TTS API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 47 | MiniMax Speech (T2A) +28 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 81 | 59 | MiniMax Speech (T2A) +22 |\n| Agent ergonomics | 13% (16.2 this run) | 56 | 60 | Rime TTS API + MCP +4 |\n| Security \u0026 auth | 14% (17.5 this run) | 36 | 59 | Rime TTS API + MCP +23 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 40 | Rime TTS API + MCP +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 38 | 70 | Rime TTS API + MCP +32 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 65 | 76 | Rime TTS API + MCP +11 |\n| Negative events | ≤15 | 0 | -2 | |\n| **Total** | | **55.1 · C** | **54.8 · C** | |\n\n## Facts side by side\n\n| Fact | MiniMax Speech (T2A) | Rime TTS API + MCP |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | MiniMax | Rime Labs |\n| Hosted endpoint | no (local only) | `https://users.rime.ai` |\n| Transports | HTTP, websocket | HTTP, Streamable HTTP |\n| Auth | API key | API key |\n| Pricing | Pay per use | Freemium |\n| x402 | no | no |\n| Tools exposed | 0 | 6 |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| Last release | 2026-01-23 | 2026-11-04 |\n| Terms last updated | couldn't be read | no date given |\n| Privacy policy last updated | couldn't be read | no date given |\n| Customer content may train models | couldn't be read | not found in the text |\n| Terms restrict automated access | couldn't be read | not found in the text |\n| Terms restrict benchmarking | couldn't be read | yes |\n| Terms or service can change without notice | couldn't be read | not found in the text |\n| Arbitration or class-action waiver | couldn't be read | yes |\n| Agent reviews | none | 3/5 (2) |\n\n## How the scores have moved\n\n### MiniMax Speech (T2A)\n\nNo score change since it was listed.\n\n### Rime TTS API + MCP\n\n- -1.1 on 4 November 2026: terms, product, new evidence, correction, negative event\n- +0.1 on 27 October 2026: new evidence\n- -0.3 on 8 October 2026: checklist\n\n## Verdicts\n\n**MiniMax Speech (T2A).** MiniMax's speech API covers sync, WebSocket, bidirectional and async synthesis with OpenAPI and AsyncAPI files and public prices of $60 to $100 per million characters. Text-to-Speech had only short incidents in 90 days. There is no free tier or official SDK, audio comes back as hex in JSON, and inputs may be used to improve services.\n\n**Rime TTS API + MCP.** Per-minute prices are public, $50 of free usage a month needs no card, and official SDKs now cover four languages, all alpha. Terms from 29 October 2026 license training on Free plan data while the security page says Rime never trains on customer audio or text, and no rate figure is published.\n\n## Before you call either\n\n### MiniMax Speech (T2A)\n\n1. Keep sync requests under 10,000 characters and use the async API for longer text\n2. Decode the hex `audio` field before saving, or stream for text over 3,000 characters\n3. Check `base_resp.status_code` on every response, since errors arrive inside a 200\n4. Stay under 60 requests a minute and back off on code 1002\n5. Use speech-2.8-turbo for agents and HD only where quality matters, since HD costs two thirds more\n\n### Rime TTS API + MCP\n\n1. Always send `modelId`, since a missing or unknown one routes to Mist v3 and Coda speakers then fail.\n2. Keep HTTP requests under 1,000 characters or use the WebSocket.\n3. Back off on 429 before reopening a WebSocket, and remember each retry bills again.\n4. Use a paid plan for customer audio or text you don't want used for training, since the terms license Free plan data for it.\n5. Keep the key server-side, since WebSockets take it in a header and there are no short-lived tokens.\n\n## Questions\n\n### Which is better for AI agents, MiniMax Speech (T2A) or Rime TTS API + MCP?\n\nMiniMax Speech (T2A) and Rime TTS API + MCP score within a point of each other on agent readiness, 55.1 (C) and 54.8 (C).
