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.

NEARAI_MODEL=claude-3-5-sonnet-20241022
NEARAI_BASE_URL=https://private.near.ai

Anthropic (Claude)

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)

LLM_BACKEND=openai
OPENAI_API_KEY=sk-...

Popular models: gpt-4o, gpt-4o-mini, o3-mini

Ollama (local)

Install Ollama from ollama.com, pull a model, then:

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 routes to 300+ models from a single API key.

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
GPT-4o openai/gpt-4o
Llama 4 Maverick meta-llama/llama-4-maverick
Gemini 2.0 Flash google/gemini-2.0-flash-001
Mistral Small mistralai/mistral-small-3.1-24b-instruct

Browse all models at openrouter.ai/models.

Together AI

Together AI provides fast inference for open-source models.

LLM_BACKEND=openai_compatible
LLM_BASE_URL=https://api.together.xyz/v1
LLM_API_KEY=...
LLM_MODEL=meta-llama/Llama-3.3-70B-Instruct-Turbo

Popular Together AI model IDs:

Llama 3.3 70B meta-llama/Llama-3.3-70B-Instruct-Turbo
DeepSeek R1 deepseek-ai/DeepSeek-R1
Qwen 2.5 72B Qwen/Qwen2.5-72B-Instruct-Turbo

Fireworks AI

Fireworks AI offers fast inference with compound AI system support.

LLM_BACKEND=openai_compatible
LLM_BASE_URL=https://api.fireworks.ai/inference/v1
LLM_API_KEY=fw_...
LLM_MODEL=accounts/fireworks/models/llama4-maverick-instruct-basic

vLLM / LiteLLM (self-hosted)

For self-hosted inference servers:

LLM_BACKEND=openai_compatible
LLM_BASE_URL=http://localhost:8000/v1
LLM_API_KEY=token-abc123        # set to any string if auth is not configured
LLM_MODEL=meta-llama/Llama-3.1-8B-Instruct

LiteLLM proxy (forwards to any backend, including Bedrock, Vertex, Azure):

LLM_BACKEND=openai_compatible
LLM_BASE_URL=http://localhost:4000/v1
LLM_API_KEY=sk-...
LLM_MODEL=gpt-4o                 # as configured in litellm config.yaml

LM Studio (local GUI)

Start LM Studio's local server, then:

LLM_BACKEND=openai_compatible
LLM_BASE_URL=http://localhost:1234/v1
LLM_MODEL=llama-3.2-3b-instruct-q4_K_M
# LLM_API_KEY is not required for LM Studio

Using the Setup Wizard

Instead of editing .env manually, run the onboarding wizard:

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.
