# Models CLI

See [/concepts/model-failover](/concepts/model-failover) for auth profile
rotation, cooldowns, and how that interacts with fallbacks.
Quick provider overview + examples: [/concepts/model-providers](/concepts/model-providers).

## How model selection works

gensparx selects models in this order:

1. **Primary** model (`agents.defaults.model.primary` or `agents.defaults.model`).
2. **Fallbacks** in `agents.defaults.model.fallbacks` (in order).
3. **Provider auth failover** happens inside a provider before moving to the
   next model.

Related:

- `agents.defaults.models` is the allowlist/catalog of models gensparx can use (plus aliases).
- `agents.defaults.imageModel` is used **only when** the primary model can’t accept images.
- Per-agent defaults can override `agents.defaults.model` via `agents.list[].model` plus bindings (see [/concepts/multi-agent](/concepts/multi-agent)).

## Quick model policy

- Set your primary to the strongest latest-generation model available to you.
- Use fallbacks for cost/latency-sensitive tasks and lower-stakes chat.
- For tool-enabled agents or untrusted inputs, avoid older/weaker model tiers.

## Setup wizard (recommended)

If you don’t want to hand-edit config, run the onboarding wizard:

```bash
gensparx onboard
```

It can set up model + auth for common providers, including **OpenAI Code (Codex)
subscription** (OAuth) and **Anthropic** (API key or `claude setup-token`).

## Config keys (overview)

- `agents.defaults.model.primary` and `agents.defaults.model.fallbacks`
- `agents.defaults.imageModel.primary` and `agents.defaults.imageModel.fallbacks`
- `agents.defaults.models` (allowlist + aliases + provider params)
- `models.providers` (custom providers written into `models.json`)

Model refs are normalized to lowercase. Provider aliases like `z.ai/*` normalize
to `zai/*`.

Provider configuration examples (including OpenCode Zen) live in
[/gateway/configuration](/gateway/configuration#opencode-zen-multi-model-proxy).

## “Model is not allowed” (and why replies stop)

If `agents.defaults.models` is set, it becomes the **allowlist** for `/model` and for
session overrides. When a user selects a model that isn’t in that allowlist,
gensparx returns:

```
Model "provider/model" is not allowed. Use /model to list available models.
```

This happens **before** a normal reply is generated, so the message can feel
like it “didn’t respond.” The fix is to either:

- Add the model to `agents.defaults.models`, or
- Clear the allowlist (remove `agents.defaults.models`), or
- Pick a model from `/model list`.

Example allowlist config:

```json5
{
  agent: {
    model: { primary: "anthropic/claude-sonnet-4-5" },
    models: {
      "anthropic/claude-sonnet-4-5": { alias: "Sonnet" },
      "anthropic/claude-opus-4-6": { alias: "Opus" },
    },
  },
}
```

## Switching models in chat (`/model`)

You can switch models for the current session without restarting:

```
/model
/model list
/model 3
/model openai/gpt-5.2
/model status
```

Notes:

- `/model` (and `/model list`) is a compact, numbered picker (model family + available providers).
- On Discord, `/model` and `/models` open an interactive picker with provider and model dropdowns plus a Submit step.
- `/model <#>` selects from that picker.
- `/model status` is the detailed view (auth candidates and, when configured, provider endpoint `baseUrl` + `api` mode).
- Model refs are parsed by splitting on the **first** `/`. Use `provider/model` when typing `/model <ref>`.
- If the model ID itself contains `/` (OpenRouter-style), you must include the provider prefix (example: `/model openrouter/moonshotai/kimi-k2`).
- If you omit the provider, gensparx treats the input as an alias or a model for the **default provider** (only works when there is no `/` in the model ID).

## CLI commands

```bash
gensparx models list
gensparx models status
gensparx models set <provider/model>
gensparx models set-image <provider/model>

gensparx models aliases list
gensparx models aliases add <alias> <provider/model>
gensparx models aliases remove <alias>

gensparx models fallbacks list
gensparx models fallbacks add <provider/model>
gensparx models fallbacks remove <provider/model>
gensparx models fallbacks clear

gensparx models image-fallbacks list
gensparx models image-fallbacks add <provider/model>
gensparx models image-fallbacks remove <provider/model>
gensparx models image-fallbacks clear
```

`gensparx models` (no subcommand) is a shortcut for `models status`.

### `models list`

Shows configured models by default. Useful flags:

- `--all`: full catalog
- `--local`: local providers only
- `--provider <name>`: filter by provider
- `--plain`: one model per line
- `--json`: machine‑readable output

### `models status`

Shows the resolved primary model, fallbacks, image model, and an auth overview
of configured providers. It also surfaces OAuth expiry status for profiles found
in the auth store (warns within 24h by default). `--plain` prints only the
resolved primary model.
OAuth status is always shown (and included in `--json` output). If a configured
provider has no credentials, `models status` prints a **Missing auth** section.
JSON includes `auth.oauth` (warn window + profiles) and `auth.providers`
(effective auth per provider).
Use `--check` for automation (exit `1` when missing/expired, `2` when expiring).

Auth choice is provider/account dependent. For always-on gateway hosts, API keys are usually the most predictable; subscription token flows are also supported.

Example (Anthropic setup-token):

```bash
claude setup-token
gensparx models status
```

## Scanning (OpenRouter free models)

`gensparx models scan` inspects OpenRouter’s **free model catalog** and can
optionally probe models for tool and image support.

Key flags:

- `--no-probe`: skip live probes (metadata only)
- `--min-params <b>`: minimum parameter size (billions)
- `--max-age-days <days>`: skip older models
- `--provider <name>`: provider prefix filter
- `--max-candidates <n>`: fallback list size
- `--set-default`: set `agents.defaults.model.primary` to the first selection
- `--set-image`: set `agents.defaults.imageModel.primary` to the first image selection

Probing requires an OpenRouter API key (from auth profiles or
`OPENROUTER_API_KEY`). Without a key, use `--no-probe` to list candidates only.

Scan results are ranked by:

1. Image support
2. Tool latency
3. Context size
4. Parameter count

Input

- OpenRouter `/models` list (filter `:free`)
- Requires OpenRouter API key from auth profiles or `OPENROUTER_API_KEY` (see [/environment](/help/environment))
- Optional filters: `--max-age-days`, `--min-params`, `--provider`, `--max-candidates`
- Probe controls: `--timeout`, `--concurrency`

When run in a TTY, you can select fallbacks interactively. In non‑interactive
mode, pass `--yes` to accept defaults.

## Models registry (`models.json`)

Custom providers in `models.providers` are written into `models.json` under the
agent directory (default `~/.gensparx/agents/<agentId>/models.json`). This file
is merged by default unless `models.mode` is set to `replace`.

Merge mode precedence for matching provider IDs:

- Non-empty `apiKey`/`baseUrl` already present in the agent `models.json` win.
- Empty or missing agent `apiKey`/`baseUrl` fall back to config `models.providers`.
- Other provider fields are refreshed from config and normalized catalog data.
