description: Add or edit a non-chat (tts/image/embedding) model row in ~/.omp/agent/models.yml without disabling every custom provider
---

# Scope

`~/.omp/agent/models.yml` (or `models.yaml`) on a workstation: adding a **runner**
model row (TTS / image / embedding / rerank / video) alongside chat providers.

# The landmine

Provider-level `api` accepts **only chat/judge transports**:
`openai-completions`, `openai-responses`, `openai-codex-responses`,
`azure-openai-responses`, `anthropic-messages`, `bedrock-converse-stream`,
`google-generative-ai`, `google-gemini-cli`, `google-vertex`,
`openrouter-decisions`, `typesafe`.

Naming a runner API (`openai-speech`, `openai-images`, `openai-embeddings`, …)
at **provider** level fails whole-file validation, and the failure mode is not
scoped to your provider:

```
Warning: models.yml validation failed — custom providers disabled
  Failed to load config file models, Schema error: providers.<id>.api: must be "openai-completions", …
```

Every custom provider disappears from the registry (fleet chat endpoints stop
resolving) and `omp models` lists only built-in locals. Measured 2026-10-18.

# Correct shape

Runner api goes on the **model entry only**; `auth: none` satisfies the
credential requirement; omit `contextWindow`/`maxTokens` (the positivity check
fires only when they are provided — `omp models` still prints filled defaults,
which the runner transport never reads).

```yaml
  "frank-tts (dankclaw)":
    baseUrl: http://192.168.0.143:7772/v1   # no `api:` here
    auth: none
    models:
      - id: frank-tts
        name: "frank-tts (dankclaw) — cloned voices"
        api: openai-speech                   # runner api on the model
        input: [text]
```

Roles live in `config.yml` (`modelRoles`), not in `models.yml`. Kind roles
(`image`, `web`, `speech`, `dictation`, `judge`) take no `:thinking` suffix.

# Verify after every edit (never assume the file loaded)

```bash
omp models --kind tts --no-extensions      # the new row must appear
omp models --no-extensions | grep -E '<each fleet chat model>'   # and still be listed
omp models | grep -c 'validation failed'   # must be 0
```

A run that lists only built-ins means your row broke the file — revert before
yielding.

# Speech transport contract (`openai-speech`)

Body is `{model, input, response_format, voice?, speed?}`; `voice` is forwarded
only when explicitly set; `sample_rate`/`bit_rate` **throw**
(`openai-speech does not support sampleRate`). Codec comes from the
`output_path` suffix; 15 000-character cap. An unknown `voice` name is a server
error, not a fallback — and `auth: none` makes a dead endpoint read as
*available*, so point `modelRoles.speech` at such a provider only after it has
answered a real synthesis.
