- Use mmx to generate text, images, video, and speech, and to transcribe audio, via the MiniMax AI platform. Use when the user wants to create media content, chat with MiniMax models, transcribe audio to text, perform web search, or manage MiniMax API resources from the terminal.
# MiniMax CLI — Agent Skill Guide
Use `mmx` to generate text, images, video, speech, transcribe audio, and perform web search via the MiniMax AI platform.
## Prerequisites
```bash
# Install
npm install -g mmx-cli
# Auth (OAuth persists to ~/.mmx/credentials.json, API key persists to ~/.mmx/config.json)
mmx auth login --api-key sk-xxxxx
# Verify active auth source
mmx auth status
# Or pass per-call
mmx text chat --api-key sk-xxxxx --message "Hello"
```
Region is auto-detected. Override with `--region global` or `--region cn`.

## Agent Flags
Always use these flags in non-interactive (agent/CI) contexts:
| Flag | Purpose |
|---|---|
| `--non-interactive` | Fail fast on missing args instead of prompting |
| `--quiet` | Suppress spinners/progress; stdout is pure data |
| `--output json` | Machine-readable JSON output |
| `--async` | Return task ID immediately (video generation) |
| `--dry-run` | Preview the API request without executing |
| `--yes` | Skip confirmation prompts |
---
## Commands

### video generate
Generate video. Default model: `MiniMax-Hailuo-2.3` (or `MiniMax-Hailuo-2.3-Fast` for fast mode with `--image`). This is an async task — by default it polls until completion.
For `MiniMax-H3` — text-to-video, first/last-frame, multimodal reference image/video/audio generation, prompt construction, and failure handling — use the dedicated [mmx-h3-video skill](h3-video/SKILL.md) instead.
```bash
mmx video generate --prompt <text> [flags]
```

| `--async` | boolean | Return task ID immediately |
| `--no-wait` | boolean | Same as `--async` |
| `--poll-interval <seconds>` | number | Polling interval (default: 5) |
```bash
# Non-blocking: get task ID
mmx video generate --prompt "A robot." --async --quiet
# stdout: {"taskId":"..."}
# Blocking: wait and get file path
mmx video generate --prompt "Ocean waves." --download ocean.mp4 --quiet
# stdout: ocean.mp4
```
### video task get
Query status of a video generation task.
```bash
mmx video task get --task-id <id> [--output json]
```
### video download
Download a completed video by task ID.
```bash
mmx video download --file-id <id> [--out <path>]
```

| `--sound-effect <effect>` | string | Add sound effect |
| `--out <path>` | string | Save audio to file |
| `--stream` | boolean | Stream raw audio to stdout |
```bash
mmx speech synthesize --text "Hello world" --out hello.mp3 --quiet
# stdout: hello.mp3
mmx speech synthesize --text "Hello" --subtitles --out hello.mp3

| `--model <model>` | string | `asr-1.0` (default) |
| `--response-format <fmt>` | string | `json` (default), `verbose_json`, `srt`, `vtt` |
| `--language <code>` | string | BCP-47 language hint (`zh`, `en`, `ja`, ...). Omit for automatic/mixed-language detection |
| `--timestamp-level <level>` | string | `sentence` (default) or `word`; applies to `verbose_json` / `srt` / `vtt` |
| `--stream` | boolean | Stream incremental text to stdout. Requires `--response-format json` |
| `--out <path>` | string | Write the result to a file instead of stdout |
```bash
mmx speech transcribe --file meeting.mp3
# stdout: transcript text
mmx speech transcribe --file call.mp3 --language zh --output json
# stdout: {"text":"...","duration":12.3,"trace_id":"..."}
mmx speech transcribe --file talk.mp3 --response-format verbose_json --timestamp-level word --output json
# stdout: adds n_speakers and word-level segments
mmx speech transcribe --file talk.mp3 --response-format srt --out talk.srt
# saves talk.srt; stdout: {"saved":".../talk.srt"}
mmx speech transcribe --file long.mp3 --stream
# stdout: text as it is recognized (add --output text when piping)
```
Notes:
- `mmx speech recognize` is an alias for `mmx speech transcribe`.
- `--stream` cannot be combined with `--out`; redirect stdout instead.
- `--stream` prints deltas only in text output mode. stdout that is not a terminal defaults to
`json` (as everywhere else in this CLI), which accumulates the streamed text into one JSON
result — pass `--output text` to pipe streamed text, e.g.
`mmx speech transcribe --file long.mp3 --stream --output text > transcript.txt`.
- `srt` / `vtt` results are subtitle documents and are printed or saved verbatim.
- Without `--out`, `--output json` prints the full API response for `json` / `verbose_json`.
Plain-text output prints the transcript only, so add `--output json` to read `n_speakers`
and `segments`.
- A stream that ends without the API's final event raises a warning on stderr, since the
transcript may be truncated.
- Input validation (missing file, unsupported format, over 50 MB, `--stream` with a non-json
format) fails before anything is uploaded; the API stays the authority for the 500 s duration
limit and codec support.
