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- Smallest.ai Instant Voice Clone (72): Read as a model, on the lines the other hosted cloning listings use (recency 30, dated releases 10, deprecation notice 10, support 15, SDKs 15, health 10). The models changelog has entries dated 29 October 2026 (30). Entries on 21, 24, 26, 28 and 29 October and in September (10). The deprecation page dates each retirement, such as `lightning-v3.1` and its clones on 30 November 2026 with steps to migrate, though when the clone retirement was first announced wasn't found (7 of 10). Public changelog, support@smallest.ai and a Discord server, with no evidence read of how they answer (10 of 15). `smallestai` on PyPI released 5.12.3 to 5.14.0 between 1 and 7 October 2026, from a repository under fern-demo. The npm package is stale (10 of 15). Package repositories weren't cloned (5 of 10). 30+10+7+10+10+5 = 72.\n\n### Reliability: MiniMax Voice Clone and Voice Design +10\n\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- Smallest.ai Instant Voice Clone (65): Graded on the hosted cloning API with the hosted lines. status.smallest.ai is the vendor's own status page with components per region and a dated incident feed (20). The feed, read on 6 November, has dozens of automated outage alerts on the API components in the 90 days from 8 August, most a few minutes long, and a cluster across every API region from 13 to 17 September. The 60-day uptime bars read 99.790 per cent for API USA and 99.849 per cent for API Global. No single outage of an hour was found, but repeated wide outages read as one major episode (10). Rate limits are published for TTS (one concurrent request, 100 a minute on pay as you go), while the per-organisation clone limit has no number (10 of 15). The limits page says to handle 429 gracefully and the clone errors say to retry a timeout, with no Retry-After, backoff figures or idempotency key (5 of 15). The pricing table lists an Enterprise SLA of 99.99 per cent (10). Instant cloning carries no beta label (10). 20+10+10+5+10+10 = 65.\n\n### Security \u0026 auth: Smallest.ai Instant Voice Clone +9\n\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- Smallest.ai Instant Voice Clone (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. Plain bearer keys, shown once, revocable, with rotation guidance and no scopes. Short-lived access tokens are refused on the cloning endpoint (20 of 30). No consent or verification field. The Terms let Smallest demand proof that the speaker authorised a clone and remove voices without it, and the prohibited use policy bars unauthorised impersonation. No watermark found (6 of 20). The Terms say Smallest won't use User Content or Input to train its services. Zero retention and retention windows are Enterprise options, and no retention period for samples is published (9 of 15). A usage dashboard, with no audit log found (5 of 15). A valid security.txt naming security@smallest.ai and a HIPAA business associate agreement page. The trust centre didn't answer through our proxy, so no certification was confirmed first-hand, and no bug bounty was found (8 of 20). 20+6+9+5+8 = 48.\n\n### Schema \u0026 documentation: MiniMax Voice Clone and Voice Design +8\n\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- Smallest.ai Instant Voice Clone (70): The API reference pages are generated with typed fields, enums and error schemas, but no OpenAPI file was found linked from the docs or llms.txt (5 of 25). llms.txt and a Markdown copy of every page (10). The guide says when to use the Pro pool, how to check `modelIds` before synthesis and why a mismatched clone returns empty audio, while the reference still names the retiring default (14 of 20). `model` and `language` are enums validated by the server, with required `displayName` and `file`, a 5 MB limit and MIME types listed, and `tags` as a comma-separated string (12 of 15). Examples in curl, Python and Node.js and a table of seven error cases with causes (14 of 15). Paths under `/v1`, a deprecation page with dated statuses and a models changelog with entries on 21, 24, 26, 28 and 29 October 2026 (15). 5+10+14+12+14+15 = 70.\n\n### Transparency \u0026 trust: Smallest.ai Instant Voice Clone +7\n\n- MiniMax Voice Clone and Voice Design (65): Closed API with clear terms under Singapore law and SIAC arbitration, read on 4 November from the document text the page carries (effective 30 March 2026, naming Nanonoble Pte. Ltd.), as on the minimax-api listing. The MCP servers are MIT (15 of 30, from 12). The terms and privacy policy agree on the contracting entity, that inputs (which the policy says may include voice) are processed and may be used to improve services, and that data sits in a United States data centre, with no retention period and no DPA read, which is minimax-api's 10. The speech docs still say every interface is stateless and stores no user data while also saving an activated voice permanently, and give no retention period for uploaded audio, so 2 less (8 of 30, from 5). The API release notes carry a deprecation notice dated 20 June 2025 marking the earlier text-to-voice API legacy with service continuing, and legacy speech models are labelled, with no written policy or notice period. Dated notices with no period give 15 (15 of 20, from 8). Data location stated as the United States and an EU representative named, with third parties named only by category, as on minimax-api (10 of 20, from 0). Total 48.\n- Smallest.ai Instant Voice Clone (72): Closed service with clear terms naming Smallest, Inc. under California law, effective 21 October 2026 (15 of 30). The Terms rule out training on customer content, the Privacy Policy (18 September 2026) gives retention criteria but no periods, and the Zero Data Retention page is specific about Enterprise options, with nothing on how long cloning samples are kept (16 of 30). A deprecation page with dated statuses (deprecated, rejects, removed, scheduled, retiring) and migration targets (16 of 20). Two regions named with locations. No sub-processor list was found and a DPA page exists unread (10 of 20). 15+16+16+10 = 57.\n\n### Agent ergonomics: Smallest.ai Instant Voice Clone +6\n\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- Smallest.ai Instant Voice Clone (62): The clone response is a compact object with the voice ID, status and signed URLs to sample clips rather than inline audio (20 of 25). The list call returns every clone on the organisation with no pagination or filter found (10 of 20). Errors carry a message and, on 500, an `error_code` enum with a stated fix, such as retrying `voice_clone_timeout` (16 of 20). No idempotency key, and retrying a timeout can leave a duplicate clone, with deletion through an oddly named route (4 of 20). Two required fields. The Python SDK `smallestai` 5.14.0 is current, while the npm package `smallestai` was last published on 16 April 2025 (12 of 15). 20+10+16+4+12 = 62.\n\n## Score by category\n\n| Category | Weight | MiniMax Voice Clone and Voice Design | Smallest.ai Instant Voice Clone | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 65 | MiniMax Voice Clone and Voice Design +10 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 78 | 70 | MiniMax Voice Clone and Voice Design +8 |\n| Agent ergonomics | 13% (16.2 this run) | 56 | 62 | Smallest.ai Instant Voice Clone +6 |\n| Security \u0026 auth | 14% (17.5 this run) | 39 | 48 | Smallest.ai Instant Voice Clone +9 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 20 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 38 | 72 | Smallest.ai Instant Voice Clone +34 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 65 | 72 | Smallest.ai Instant Voice Clone +7 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **55.1 · C** | **58 · C** | |\n\n## Facts side by side\n\n| Fact | MiniMax Voice Clone and Voice Design | Smallest.ai Instant Voice Clone |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | MiniMax | Smallest, Inc. |\n| Hosted endpoint | `https://api.minimax.io` | `https://api.smallest.ai/waves/v1/voice-cloning` |\n| Transports | HTTP, stdio | HTTP |\n| Auth | API key | API key |\n| Pricing | Pay per use | Pay per use |\n| Price for voice cloning | $60 per 1M characters | $17.50 per 1M characters |\n| x402 | no | no |\n| Licence | Proprietary API under MiniMax's platform terms.

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**Smallest.ai Instant Voice Clone.** One multipart POST clones a voice from 5 to 15 seconds of audio and returns sample clips, with dated deprecation notices and current changelog entries. The endpoint still defaults to a model whose clones stop working on 30 November 2026, there's no consent field or clone price, and the status feed shows frequent short API outages.\n\n## Before you call either\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### Smallest.ai Instant Voice Clone\n\n1. Always pass `model=lightning-v3.1-pro`. The default `lightning-v3.1` clones stop working on 30 November 2026\n2. Use the returned `voiceId` with the matching TTS model and check `modelIds` from `GET /waves/v1/voice-cloning` if a TTS call returns a tiny WAV\n3.
