# LLM Provider Configuration
|
||||
|
||||
IronClaw defaults to NEAR AI for model access, but supports any OpenAI-compatible
|
||||
endpoint as well as Anthropic and Ollama directly. This guide covers the most common
|
||||
configurations.
|
||||
|
||||
## Provider Overview
|
||||
|
||||
| Provider | Backend value | Requires API key | Notes |
|
||||
|---|---|---|---|
|
||||
| NEAR AI | `nearai` | OAuth (browser) | Default; multi-model |
|
||||
| Anthropic | `anthropic` | `ANTHROPIC_API_KEY` | Claude models |
|
||||
| OpenAI | `openai` | `OPENAI_API_KEY` | GPT models |
|
||||
| Ollama | `ollama` | No | Local inference |
|
||||
| OpenRouter | `openai_compatible` | `LLM_API_KEY` | 300+ models |
|
||||
| Together AI | `openai_compatible` | `LLM_API_KEY` | Fast inference |
|
||||
| Fireworks AI | `openai_compatible` | `LLM_API_KEY` | Fast inference |
|
||||
| vLLM / LiteLLM | `openai_compatible` | Optional | Self-hosted |
|
||||
| LM Studio | `openai_compatible` | No | Local GUI |
|
||||
|
||||
---
|
||||
|
||||
## NEAR AI (default)
|
||||
|
||||
No additional configuration required. On first run, `ironclaw onboard` opens a browser
|
||||
for OAuth authentication. Credentials are saved to `~/.ironclaw/session.json`.
|
||||
|
||||
```env
|
||||
NEARAI_MODEL=claude-3-5-sonnet-20241022
|
||||
NEARAI_BASE_URL=https://private.near.ai
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Anthropic (Claude)
|
||||
|
||||
```env
|
||||
LLM_BACKEND=anthropic
|
||||
ANTHROPIC_API_KEY=sk-ant-...
|
||||
```
|
||||
|
||||
Popular models: `claude-sonnet-4-20250514`, `claude-3-5-sonnet-20241022`, `claude-3-5-haiku-20241022`
|
||||
|
||||
---
|
||||
|
||||
## OpenAI (GPT)
|
||||
|
||||
```env
|
||||
LLM_BACKEND=openai
|
||||
OPENAI_API_KEY=sk-...
|
||||
```
|
||||
|
||||
Popular models: `gpt-4o`, `gpt-4o-mini`, `o3-mini`
|
||||
|
||||
---
|
||||
|
||||
## Ollama (local)
|
||||
|
||||
Install Ollama from [ollama.com](https://ollama.com), pull a model, then:
|
||||
|
||||
```env
|
||||
LLM_BACKEND=ollama
|
||||
OLLAMA_MODEL=llama3.2
|
||||
# OLLAMA_BASE_URL=http://localhost:11434 # default
|
||||
```
|
||||
|
||||
Pull a model first: `ollama pull llama3.2`
|
||||
|
||||
---
|
||||
|
||||
## OpenAI-Compatible Endpoints
|
||||
|
||||
All providers below use `LLM_BACKEND=openai_compatible`. Set `LLM_BASE_URL` to the
|
||||
provider's OpenAI-compatible endpoint and `LLM_API_KEY` to your API key.
|
||||
|
||||
### OpenRouter
|
||||
|
||||
[OpenRouter](https://openrouter.ai) routes to 300+ models from a single API key.
|
||||
|
||||
```env
|
||||
LLM_BACKEND=openai_compatible
|
||||
LLM_BASE_URL=https://openrouter.ai/api/v1
|
||||
LLM_API_KEY=sk-or-...
|
||||
LLM_MODEL=anthropic/claude-sonnet-4
|
||||
```
|
||||
|
||||
Popular OpenRouter model IDs:
|
||||
|
||||
| Model | ID |
|
||||
|---|---|
|
||||
| Claude Sonnet 4 | `anthropic/claude-sonnet-4` |

## Using the Setup Wizard
|
||||
|
||||
Instead of editing `.env` manually, run the onboarding wizard:
|
||||
|
||||
```bash
|
||||
ironclaw onboard
|
||||
```
|
||||
|
||||
Select **"OpenAI-compatible"** for OpenRouter, Together AI, Fireworks, vLLM, LiteLLM,
|
||||
or LM Studio. You will be prompted for the base URL and (optionally) an API key.
|
||||
The model name is configured in the following step.
