# Model providers

This page covers **LLM/model providers** (not chat channels like WhatsApp/Telegram).
For model selection rules, see [/concepts/models](/concepts/models).

## Quick rules

- Model refs use `provider/model` (example: `opencode/claude-opus-4-6`).
- If you set `agents.defaults.models`, it becomes the allowlist.
- CLI helpers: `gensparx onboard`, `gensparx models list`, `gensparx models set <provider/model>`.

## API key rotation

- Supports generic provider rotation for selected providers.
- Configure multiple keys via:
  - `GENSPARX_LIVE_<PROVIDER>_KEY` (single live override, highest priority)
  - `<PROVIDER>_API_KEYS` (comma or semicolon list)
  - `<PROVIDER>_API_KEY` (primary key)
  - `<PROVIDER>_API_KEY_*` (numbered list, e.g. `<PROVIDER>_API_KEY_1`)
- For Google providers, `GOOGLE_API_KEY` is also included as fallback.
- Key selection order preserves priority and deduplicates values.
- Requests are retried with the next key only on rate-limit responses (for example `429`, `rate_limit`, `quota`, `resource exhausted`).
- Non-rate-limit failures fail immediately; no key rotation is attempted.
- When all candidate keys fail, the final error is returned from the last attempt.

## Built-in providers (pi-ai catalog)

gensparx ships with the pi‑ai catalog. These providers require **no**
`models.providers` config; just set auth + pick a model.

### OpenAI

- Provider: `openai`
- Auth: `OPENAI_API_KEY`
- Optional rotation: `OPENAI_API_KEYS`, `OPENAI_API_KEY_1`, `OPENAI_API_KEY_2`, plus `GENSPARX_LIVE_OPENAI_KEY` (single override)
- Example models: `openai/gpt-5.4`, `openai/gpt-5.4-pro`
- CLI: `gensparx onboard --auth-choice openai-api-key`
- Default transport is `auto` (WebSocket-first, SSE fallback)
- Override per model via `agents.defaults.models["openai/<model>"].params.transport` (`"sse"`, `"websocket"`, or `"auto"`)
- OpenAI Responses WebSocket warm-up defaults to enabled via `params.openaiWsWarmup` (`true`/`false`)
- OpenAI priority processing can be enabled via `agents.defaults.models["openai/<model>"].params.serviceTier`

```json5
{
  agents: { defaults: { model: { primary: "openai/gpt-5.4" } } },
}
```

### Anthropic

- Provider: `anthropic`
- Auth: `ANTHROPIC_API_KEY` or `claude setup-token`
- Optional rotation: `ANTHROPIC_API_KEYS`, `ANTHROPIC_API_KEY_1`, `ANTHROPIC_API_KEY_2`, plus `GENSPARX_LIVE_ANTHROPIC_KEY` (single override)
- Example model: `anthropic/claude-opus-4-6`
- CLI: `gensparx onboard --auth-choice token` (paste setup-token) or `gensparx models auth paste-token --provider anthropic`
- Policy note: setup-token support is technical compatibility; Anthropic has blocked some subscription usage outside Claude Code in the past. Verify current Anthropic terms and decide based on your risk tolerance.
- Recommendation: Anthropic API key auth is the safer, recommended path over subscription setup-token auth.

```json5
{
  agents: { defaults: { model: { primary: "anthropic/claude-opus-4-6" } } },
}
```

### OpenAI Code (Codex)

- Provider: `openai-codex`
- Auth: OAuth (ChatGPT)
- Example model: `openai-codex/gpt-5.4`
- CLI: `gensparx onboard --auth-choice openai-codex` or `gensparx models auth login --provider openai-codex`
- Default transport is `auto` (WebSocket-first, SSE fallback)
- Override per model via `agents.defaults.models["openai-codex/<model>"].params.transport` (`"sse"`, `"websocket"`, or `"auto"`)
- Policy note: OpenAI Codex OAuth is explicitly supported for external tools/workflows like Gensparx.

```json5
{
  agents: { defaults: { model: { primary: "openai-codex/gpt-5.4" } } },
}
```

### OpenCode Zen

- Provider: `opencode`
- Auth: `OPENCODE_API_KEY` (or `OPENCODE_ZEN_API_KEY`)
- Example model: `opencode/claude-opus-4-6`
- CLI: `gensparx onboard --auth-choice opencode-zen`

```json5
{
  agents: { defaults: { model: { primary: "opencode/claude-opus-4-6" } } },
}
```

### Google Gemini (API key)

- Provider: `google`
- Auth: `GEMINI_API_KEY`
- Optional rotation: `GEMINI_API_KEYS`, `GEMINI_API_KEY_1`, `GEMINI_API_KEY_2`, `GOOGLE_API_KEY` fallback, and `GENSPARX_LIVE_GEMINI_KEY` (single override)
- Example model: `google/gemini-3-pro-preview`
- CLI: `gensparx onboard --auth-choice gemini-api-key`

### Google Vertex, Antigravity, and Gemini CLI

- Providers: `google-vertex`, `google-antigravity`, `google-gemini-cli`
- Auth: Vertex uses gcloud ADC; Antigravity/Gemini CLI use their respective auth flows
- Caution: Antigravity and Gemini CLI OAuth in gensparx are unofficial integrations. Some users have reported Google account restrictions after using third-party clients. Review Google terms and use a non-critical account if you choose to proceed.
- Antigravity OAuth is shipped as a bundled plugin (`google-antigravity-auth`, disabled by default).
  - Enable: `gensparx plugins enable google-antigravity-auth`
  - Login: `gensparx models auth login --provider google-antigravity --set-default`
- Gemini CLI OAuth is shipped as a bundled plugin (`google-gemini-cli-auth`, disabled by default).
  - Enable: `gensparx plugins enable google-gemini-cli-auth`
  - Login: `gensparx models auth login --provider google-gemini-cli --set-default`
  - Note: you do **not** paste a client id or secret into `gensparx.json`. The CLI login flow stores
    tokens in auth profiles on the gateway host.

### Z.AI (GLM)

- Provider: `zai`
- Auth: `ZAI_API_KEY`
- Example model: `zai/glm-5`
- CLI: `gensparx onboard --auth-choice zai-api-key`

## Providers via `models.providers` (custom/base URL)

Use `models.providers` (or `models.json`) to add **custom** providers or
OpenAI/Anthropic‑compatible proxies.

### Moonshot AI (Kimi)

Moonshot uses OpenAI-compatible endpoints, so configure it as a custom provider:

- Provider: `moonshot`
- Auth: `MOONSHOT_API_KEY`

### Synthetic

Synthetic provides Anthropic-compatible models behind the `synthetic` provider:

- Provider: `synthetic`
- Auth: `SYNTHETIC_API_KEY`
- Example model: `synthetic/hf:MiniMaxAI/MiniMax-M2.5`
- CLI: `gensparx onboard --auth-choice synthetic-api-key`

```json5
{
  agents: {
    defaults: { model: { primary: "synthetic/hf:MiniMaxAI/MiniMax-M2.5" } },
  },
  models: {
    mode: "merge",
    providers: {
      synthetic: {
        baseUrl: "https://api.synthetic.new/anthropic",
        apiKey: "${SYNTHETIC_API_KEY}",
        api: "anthropic-messages",
        models: [{ id: "hf:MiniMaxAI/MiniMax-M2.5", name: "MiniMax M2.5" }],
      },
    },
  },
}
```

### MiniMax

MiniMax is configured via `models.providers` because it uses custom endpoints:

- MiniMax (Anthropic‑compatible): `--auth-choice minimax-api`
- Auth: `MINIMAX_API_KEY`

See [/providers/minimax](/providers/minimax) for setup details, model options, and config snippets.

### Ollama

Ollama is a local LLM runtime that provides an OpenAI-compatible API:

- Provider: `ollama`
- Auth: None required (local server)
- Example model: `ollama/llama3.3`
- Installation: [https://ollama.ai](https://ollama.ai)

```bash
# Install Ollama, then pull a model:
ollama pull llama3.3
```

```json5
{
  agents: {
    defaults: { model: { primary: "ollama/llama3.3" } },
  },
}
```

Ollama is automatically detected when running locally at `http://127.0.0.1:11434/v1`. See [/providers/ollama](/providers/ollama) for model recommendations and custom configuration.

### vLLM

vLLM is a local (or self-hosted) OpenAI-compatible server:

- Provider: `vllm`
- Auth: Optional (depends on your server)
- Default base URL: `http://127.0.0.1:8000/v1`

To opt in to auto-discovery locally (any value works if your server doesn’t enforce auth):

```bash
export VLLM_API_KEY="vllm-local"
```

Then set a model (replace with one of the IDs returned by `/v1/models`):

```json5
{
  agents: {
    defaults: { model: { primary: "vllm/your-model-id" } },
  },
}
```

See [/providers/vllm](/providers/vllm) for details.

### Local proxies (LM Studio, vLLM, LiteLLM, etc.)

Example (OpenAI‑compatible):

```json5
{
  agents: {
    defaults: {
      model: { primary: "lmstudio/minimax-m2.5-gs32" },
      models: { "lmstudio/minimax-m2.5-gs32": { alias: "Minimax" } },
    },
  },
  models: {
    providers: {
      lmstudio: {
        baseUrl: "http://localhost:1234/v1",
        apiKey: "LMSTUDIO_KEY",
        api: "openai-completions",
        models: [
          {
            id: "minimax-m2.5-gs32",
            name: "MiniMax M2.5",
            reasoning: false,
            input: ["text"],
            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
            contextWindow: 200000,
            maxTokens: 8192,
          },
        ],
      },
    },
  },
}
```

Notes:

- For custom providers, `reasoning`, `input`, `cost`, `contextWindow`, and `maxTokens` are optional.
  When omitted, gensparx defaults to:
  - `reasoning: false`
  - `input: ["text"]`
  - `cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 }`
  - `contextWindow: 200000`
  - `maxTokens: 8192`
- Recommended: set explicit values that match your proxy/model limits.
- For `api: "openai-completions"` on non-native endpoints (any non-empty `baseUrl` whose host is not `api.openai.com`), gensparx forces `compat.supportsDeveloperRole: false` to avoid provider 400 errors for unsupported `developer` roles.
- If `baseUrl` is empty/omitted, gensparx keeps the default OpenAI behavior (which resolves to `api.openai.com`).
- For safety, an explicit `compat.supportsDeveloperRole: true` is still overridden on non-native `openai-completions` endpoints.

## CLI examples

```bash
gensparx onboard --auth-choice opencode-zen
gensparx models set opencode/claude-opus-4-6
gensparx models list
```

See also: [/gateway/configuration](/gateway/configuration) for full configuration examples.
