Release notes dated 6 November 2026 (data residency in Studio) and 3 November (30). Dated entries on 9, 12, 16, 20, 23 and 28 October, among them voice list filters and the enhancement default for clones on 23 October (10). `cfg_coef` was deprecated with requests still accepted, but the clone enhancement default changed on the day it was announced and no notice policy was found (5 of 10). Public release notes, support@gradium.ai and a Discord server, with no evidence read of how they answer (10 of 15). `gradium` on PyPI at 0.6.4 (4 September 2026), with no SDK in a second language (10 of 15). The SDK repository was not cloned (5 of 10). 30+10+5+10+10+5 = 70.\n- MiniMax Voice Clone and Voice Design (38): The newest dated change that touches this product is `minimax-mcp-js` 0.0.18 on 21 August 2026 (per the 8 October npm reading), the day the MCP-JS repository merged its last change, and the Python server's version 0.0.19 commit of 20 August, 75 days before 4 November. Neither repository has a commit after 21 August. The newest speech model, Speech 2.8, is still dated 23 January 2026 on the model release page (20 of 30). Two package releases for one change in the last 90 days, and no dated API entries (0). The API release notes still stop at 28 October 2025. Support is by email and Discord, and the MCP repository's issue replies were not read (6 of 15). No official SDK for speech. The MCP servers were updated in August 2026 and include `voice_clone` and `voice_design` (8 of 15). The Python server has tests and moved to version 2 of the MCP SDK in August, with no CI workflow in the repository (4 of 10). Total 38.\n\n### Reliability: MiniMax Voice Clone and Voice Design +12\n\n- Gradium Voice Cloning and Voice Design (63): Graded on the hosted voice API with the hosted lines. Atlassian Statuspage at gradium.statuspage.io with five components, one of them Voice Cloning (20). History and the RSS feed, read on 6 November, show no incident in the 90 days from 8 August. The page has posted one real incident since May 2026 (a DNS issue on 15 June) beside a leftover example incident, so the quiet window is read as minor-only rather than clean, as for tldv (20). Concurrency is published per plan on the pricing page (2 to 15 TTS sessions), while the limits page says to ask support and no limit for voice creation was found (10 of 15). No 429, Retry-After or backoff guidance was found; the errors page says to open a new connection after an error, and voice creation takes a `timeout_s` (3 of 15). No SLA in the Terms or on the pricing page (0). Instant cloning carries no beta label (10). 20+20+10+3+0+10 = 63.\n- MiniMax Voice Clone and Voice Design (75): Atlassian Statuspage at status.minimax.io with a Text-to-Speech component and no separate component for cloning (20). Its history pages, read on 4 November, cover the whole 90 days from 6 August. Text-to-Speech had three incidents in that window, all titled 'Elevated errors on Text-to-Speech' and labelled major, 22 minutes on 28 September, 3 minutes on 16 October and 2 minutes on 19 October. This run reads elevated errors with no fuller scope as partial, as on the minimax-api listing, so minor only (20). Rate limits are published, 60 requests a minute for voice cloning and 20 for voice design, unchanged on 4 November (15). Error 1002 and 2045 say to retry later and avoid sudden increases, with no Retry-After, backoff figures or idempotency key found. That is wait-and-retry guidance alone, which minimax-api and minimax-video score 10 on the same error-code page (10, from 5). The terms, read on 4 November, state no SLA, and none is in the docs (0). No beta or preview label on either endpoint (10). Total 75.\n\n### Agent ergonomics: Gradium Voice Cloning and Voice Design +11\n\n- Gradium Voice Cloning and Voice Design (67): Voice objects are compact metadata (20 of 25). `GET /voices/` takes `skip` and `limit` (default 100) and since 23 October filters by `locale`, `gender` and `use_case` (20). Validation errors are structured 422 bodies, while synthesis errors arrive as plain-text HTTP 500 with a numeric code to parse (12 of 20). No idempotency key. Saving a design candidate twice answers 409, and the clone call has none (5 of 20). Three required fields with sensible defaults, and one official SDK, in Python (10 of 15). 20+20+12+5+10 = 67.\n- MiniMax Voice Clone and Voice Design (56): The clone call returns a preview URL and billing counts, but voice design returns preview audio as hex inside the JSON body, and listing with `voice_type` set to `all` returns the 300+ system voices (15 of 25). `POST /v1/get_voice` filters by voice type and has no pagination (10 of 20). Errors come as numeric codes in `base_resp` with a short remedy for each, several of them specific to cloning, inside a response documented only as 200 (13 of 20). No idempotency key. A repeated clone with the same `voice_id` fails with 2039 instead of creating a second voice, the fee applies only on first synthesis, and the MCP tools carry no read-only or destructive annotations (10 of 20). Two required fields per call. No official SDK for speech, with MCP servers in Python and JavaScript and an official CLI that does not cover cloning (8 of 15).\n\n### Payments \u0026 pricing: Gradium Voice Cloning and Voice Design +10\n\n- Gradium Voice Cloning and Voice Design (30): No x402, MPP or L402 (0). Plan prices and credits are public, 1 credit a character for speech, with no dollar price per unit, as cartesia-voice-cloning is read. Creating a clone uses no credits in the docs (10). The free plan has 45,000 credits a month, 5 custom voices and Voice Design, and the site says no credit card is required. Commercial use starts on the $12 plan (20). Signup is a browser flow in Gradium Studio (0). 0+10+20+0 = 30.\n- MiniMax Voice Clone and Voice Design (20): No x402, MPP or L402 (0). Per-unit prices are public, $1.50 a cloned voice, $3 a designed voice and $60 to $100 per million characters of speech (20). No free allowance for cloning or design is published. The rate limits page mentions a free tier without defining it (0). A person signs up in a browser, funds a balance and completes verification before the first clone (0).\n\n### Security \u0026 auth: Gradium Voice Cloning and Voice Design +9\n\n- Gradium Voice Cloning and Voice Design (48): Graded for voice cloning as the other listings in this category, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line. API keys per organisation in a header, revocable and able to expire, with no scopes found (20 of 30). No consent or verification field and no watermark. The Terms make the client obtain the consent of anyone whose voice is a sample and bar impersonation without explicit authorisation, and the API FAQ says explicit consent is required (6 of 20). The Terms grant Gradium a licence to use Client Data to improve its services and train its models, with no opt-out found, and zero data retention (paid plans) excludes voice samples, so samples are kept and may be used for training (2 of 15). Organisation roles and a member list, with no per-call audit log found (5 of 15). SOC 2 Type II and ISO 27001:2022 audited by A-LIGN, a trust centre and security@gradium.ai. No security.txt (404) and no bug bounty found (15 of 20). 20+6+2+5+15 = 48.\n- MiniMax Voice Clone and Voice Design (39): Graded for voice cloning, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line, as on the other listings in this category. Plain API keys from the console with no scopes found, and the docs say publicly leaked keys may be disabled (20 of 30). Cloning requires individual or enterprise verification of the account, input passes a content safety check, and two optional controls exist, a transcript match (`text_validation`) and a watermark tone (`aigc_watermark`, off by default). No field records the speaker's consent. The terms only have the client confirm it obtained any required consent from end users for the data it submits, with nothing on voices or likeness (8 of 20). The terms (effective 30 March 2026), read on 4 November from the document text the page carries, let MiniMax use input and generated content to provide, maintain, develop and improve its services, with no opt-out found, and the privacy policy (updated 30 March 2026) says input may include voice and rules out only training to profile or target consumers. The docs state that unused voices are deleted after 7 days and a delete call exists (5 of 15). Responses carry `usage_characters` for reconciliation and voices can be listed, with no audit log found (6 of 15). No security.txt, disclosure policy, bug bounty or certification found, and an issue opened on the MCP repository on 25 August 2026 asks for a private disclosure contact (0 of 20). Total 39.\n\n### Schema \u0026 documentation: Gradium Voice Cloning and Voice Design +5\n\n- Gradium Voice Cloning and Voice Design (83): Public OpenAPI 3.1 file at docs.gradium.ai/api-reference/openapi.json (25). llms.txt and Markdown pages (10). The guides say when to clone, design, enhance or localise a voice, and the custom-voice page explains the enhancement default and how to opt out (14 of 20). The clone body has `audio_file`, `name` and `language` required, a five-value language enum and typed defaults for `start_s`, `enhance` and `timeout_s` (14 of 15). curl and Python examples. The create call documents only 201 and 422, and the errors page covers synthesis, with plain-text 500 bodies (9 of 15). Routes carry no version, the OpenAPI file is 0.1.0, and release notes are dated per entry, newest 6 November 2026 (11 of 15). The API reference FAQ gives a 300-second session where the limits page says 3,000. 25+10+14+14+9+11 = 83.\n- MiniMax Voice Clone and Voice Design (78): OpenAPI 3.1 files for cloning, upload, voice design and voice management (25). llms.txt and a Markdown copy of every docs page (10). Field descriptions state purpose, limits and billing effects, with little on when to choose cloning over design (13 of 20). Enums for model, language and voice type, a 0 to 1 range on `accuracy` and length caps, while the `voice_id` rules sit in prose and the `file_id` description carries a sentence that belongs to `clone_prompt` (12 of 15). Request and response examples throughout and a table of 24 error codes, but only a 200 response is specified and the example response uses fields the schema does not define (10 of 15). Paths are versioned under `/v1`. The API release notes stop at 28 October 2025 and omit `text_validation` and `aigc_watermark` (8 of 15).\n\n## Score by category\n\n| Category | Weight | Gradium Voice Cloning and Voice Design | MiniMax Voice Clone and Voice Design | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 63 | 75 | MiniMax Voice Clone and Voice Design +12 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 83 | 78 | Gradium Voice Cloning and Voice Design +5 |\n| Agent ergonomics | 13% (16.2 this run) | 67 | 56 | Gradium Voice Cloning and Voice Design +11 |\n| Security \u0026 auth | 14% (17.5 this run) | 48 | 39 | Gradium Voice Cloning and Voice Design +9 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 20 | Gradium Voice Cloning and Voice Design +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 70 | 38 | Gradium Voice Cloning and Voice Design +32 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 63 | 65 | MiniMax Voice Clone and Voice Design +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **60.8 · C** | **55.1 · C** | |\n\n## Facts side by side\n\n| Fact | Gradium Voice Cloning and Voice Design | MiniMax Voice Clone and Voice Design |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | Gradium SAS | MiniMax |\n| Hosted endpoint | `https://api.gradium.ai/api/voices/` | `https://api.minimax.io` |\n| Transports | HTTP, websocket | HTTP, stdio |\n| Auth | API key | API key |\n| Pricing | Freemium | Pay per use |\n| Price for voice cloning | not published | $60 per 1M characters |\n| x402 | no | no |\n| Licence | Proprietary service under Gradium's Terms of Service (version of 19 October 2026).

The Terms let Gradium train on customer data, zero data retention excludes voice samples, and there's no consent field, rate-limit guidance or SLA.\n\n**MiniMax Voice Clone and Voice Design.** Typed OpenAPI files, published prices of $1.50 a cloned voice and $3 a designed voice, and optional transcript and watermark checks. Cloning needs individual or enterprise account verification, with no speaker consent field, and MiniMax's terms let it use inputs and generated content to develop and improve its services, with no opt-out found.\n\n## Before you call either\n\n### Gradium Voice Cloning and Voice Design\n\n1. Send `language` on every clone. It's required and must be one of en, fr, de, es or pt and match the recording\n2. Clones are enhanced by default since 23 October 2026. Pass `enhance=false` to keep the raw voice, then check `enhance` on GET\n3. Pass a clone as `voice_id` in TTS, not `voice`\n4. On a non-2xx synthesis reply, parse the `error from server \u003ccode\u003e` prefix; 1008 means a bad or revoked key\n5. Check the custom-voice allowance first. The free plan holds 5 voices shared by clones and designs\n\n### MiniMax Voice Clone and Voice Design\n\n1. Upload the sample to `POST /v1/files/upload` with `purpose=voice_clone`, then pass the integer `file_id` and a new `voice_id` of 8 to 256 characters to `POST /v1/voice_clone`\n2. Synthesise once with T2A within 7 days or the voice is deleted. A preview inside the clone call does not count\n3. Read `base_resp.status_code` on every response. Errors such as 2038 (no cloning permission) and 2039 (duplicate `voice_id`) arrive in the body\n4. Voice design returns `trial_audio` as hex in the JSON body. Write it to a file and keep it out of the model context\n5. Send `voice_type` to `POST /v1/get_voice`, because `all` also returns the 300+ system voices\n\n## Tutorials\n\n- [Upload a voice sample and clone it with MiniMax](https://www.anchorterminal.com/tutorials/minimax-voice-cloning/), for MiniMax Voice Clone and Voice Design\n\n## Questions\n\n### Which is better for AI agents, Gradium Voice Cloning and Voice Design or MiniMax Voice Clone and Voice Design?\n\nGradium Voice Cloning and Voice Design scores 60.8 (C) on agent readiness against MiniMax Voice Clone and Voice Design's 55.1 (C), and leads in 5 of 7 scored categories.
