title: Inference Providers
description: IronClaw readily supports multiple LLM providers
---
IronClaw supports multiple LLM providers out of the box, including NEAR AI , Anthropic, OpenAI, Google Gemini, GitHub Copilot, Ollama, AWS Bedrock, and any OpenAI-compatible endpoint.
Providers can be configured via environment variables or the onboarding wizard. IronClaw's modular architecture allows seamless integration with new providers by implementing the `LLMProvider` trait.
#### Configuring a Provider
To config a new provider, simply run the onboarding wizard:
```bash
ironclaw onboard --provider-only
```

## NEAR AI
```env
NEARAI_MODEL=claude-3-5-sonnet-20241022
NEARAI_BASE_URL=https://private.near.ai
```
Popular models: `Qwen/Qwen3.5-122B-A10B`, `black-forest-labs/FLUX.2-klein-4B`, `zai-org/GLM-5-FP8`
---
## 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`
---
## Google Gemini (OAuth)
Uses Google OAuth with PKCE (S256) for authentication — no API key required.
On first run, a browser opens for Google account login. Credentials (including
refresh token) are saved to `~/.gemini/oauth_creds.json` with `0600` permissions.
```env
LLM_BACKEND=gemini_oauth
GEMINI_MODEL=gemini-2.5-flash
```
### Supported features
| Feature | Status | Notes |
|--------------------|--------|-----------------------------------------------------------------------------------------------|
| Function calling | ✅ | `functionDeclarations` / `functionCall` / `functionResponse` |
| `generationConfig` | ✅ | `temperature`, `maxOutputTokens` passed from request |
| `thinkingConfig` | ✅ | `thinkingBudget`/`thinkingLevel` for thinking-capable models (does NOT set `includeThoughts`) |
| `toolConfig` | ✅ | `functionCallingConfig.mode`: `AUTO`/`ANY`/`NONE` |
| SSE streaming | ✅ | Cloud Code API with `streamGenerateContent?alt=sse` |
| Token refresh | ✅ | Automatic via refresh token |
### Popular models
| Model | ID | Notes |
|-----------------------------|--------------------------------------|-----------------------------|
| Gemini 3.1 Pro | `gemini-3.1-pro-preview` | Latest, strongest reasoning |
| Gemini 3.1 Pro Custom Tools | `gemini-3.1-pro-preview-customtools` | Enhanced tool use |
| Gemini 3 Pro | `gemini-3-pro-preview` | Preview |
| Gemini 3 Flash | `gemini-3-flash-preview` | Fast preview with thinking |
| Gemini 3.1 Flash Lite | `gemini-3.1-flash-lite-preview` | Preview, lightweight |
| Gemini 2.5 Pro | `gemini-2.5-pro` | Stable, strong reasoning |
| Gemini 2.5 Flash | `gemini-2.5-flash` | Fast, good quality |
| Gemini 2.5 Flash Lite | `gemini-2.5-flash-lite` | Fastest, lightweight |
### Cloud Code API vs standard API
Models containing `-preview` (with hyphen) or `gemini-3` in the name, as well
as any `gemini-` model with major version >= 2, route through the Cloud Code
API (`cloudcode-pa.googleapis.com`) which supports SSE streaming
and project-scoped access. Other models use the standard Generative Language
API (`generativelanguage.googleapis.com`).
---
## GitHub Copilot
GitHub Copilot exposes chat endpoint at
`https://api.githubcopilot.com`. IronClaw uses that endpoint directly through the
built-in `github_copilot` provider.
```env
LLM_BACKEND=github_copilot
GITHUB_COPILOT_TOKEN=gho_...
GITHUB_COPILOT_MODEL=gpt-4o
# Optional advanced headers if your setup needs them:
# GITHUB_COPILOT_EXTRA_HEADERS=Copilot-Integration-Id:vscode-chat
```
`ironclaw onboard` can acquire this token for you using GitHub device login. If you
already signed into Copilot through VS Code or a JetBrains IDE, you can also reuse
the `oauth_token` stored in `~/.config/github-copilot/apps.json`. If you prefer,
`LLM_BACKEND=github-copilot` also works as an alias.
Popular models vary by subscription, but `gpt-4o` is a safe default. IronClaw keeps
model entry manual for this provider because GitHub Copilot model listing may require
extra integration headers on some clients. IronClaw automatically injects the standard
VS Code identity headers (`User-Agent`, `Editor-Version`, `Editor-Plugin-Version`,
`Copilot-Integration-Id`) and lets you override them with
`GITHUB_COPILOT_EXTRA_HEADERS`.
---
## 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`
---
## MiniMax
[MiniMax](https://platform.minimax.io) provides high-performance language models with 204,800 token context windows.
```env
LLM_BACKEND=minimax
MINIMAX_API_KEY=...
```
Available models: `MiniMax-M2.7` (default), `MiniMax-M2.7-highspeed`, `MiniMax-M2.5`, `MiniMax-M2.5-highspeed`
To use the China mainland endpoint, set:
```env
MINIMAX_BASE_URL=https://api.minimaxi.com/v1
```
---
## AWS Bedrock (requires `--features bedrock`)
Uses the native AWS Converse API via `aws-sdk-bedrockruntime`. Supports standard AWS
authentication methods: IAM credentials, SSO profiles, and instance roles.
> **Build prerequisite:** The `aws-lc-sys` crate (transitive dependency via AWS SDK)
> requires **CMake** to compile. Install it before building with `--features bedrock`:
> - macOS: `brew install cmake`
> - Ubuntu/Debian: `sudo apt install cmake`
> - Fedora: `sudo dnf install cmake`
### With AWS credentials (IAM, SSO, instance roles)
```env
LLM_BACKEND=bedrock
BEDROCK_MODEL=anthropic.claude-opus-4-6-v1
BEDROCK_REGION=us-east-1
BEDROCK_CROSS_REGION=us
# AWS_PROFILE=my-sso-profile # optional, for named profiles
```
The AWS SDK credential chain automatically resolves credentials from environment
variables (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`), shared credentials file
(`~/.aws/credentials`), SSO profiles, and EC2/ECS instance roles.
### Cross-region inference
Set `BEDROCK_CROSS_REGION` to route requests across AWS regions for capacity:
| Prefix | Routing |
|-----------|----------------------------------------------|
| `us` | US regions (us-east-1, us-east-2, us-west-2) |
| `eu` | European regions |
| `apac` | Asia-Pacific regions |
| `global` | All commercial AWS regions |
| _(unset)_ | Single-region only |
### Popular Bedrock model IDs
| Model | ID |
|-------------------|---------------------------------------------|
| Claude Opus 4.6 | `anthropic.claude-opus-4-6-v1` |
| Claude Sonnet 4.5 | `anthropic.claude-sonnet-4-5-20250929-v1:0` |
| Claude Haiku 4.5 | `anthropic.claude-haiku-4-5-20251001-v1:0` |
| Amazon Nova Pro | `amazon.nova-pro-v1:0` |
| Llama 4 Maverick | `meta.llama4-maverick-17b-instruct-v1:0` |
---
## 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

```env
LLM_BACKEND=openai_compatible
LLM_BASE_URL=https://openrouter.ai/api/v1
LLM_API_KEY=sk-or-...
LLM_MODEL=anthropic/claude-sonnet-4
```

# LLM_API_KEY is not required for LM Studio
```
