# TradingAgents - AI Provider Agnostic Update - Summary
## Overview
Your TradingAgents project has been successfully updated to be **AI provider agnostic**. You can now use OpenAI, Ollama, Anthropic, Google, Groq, and many other providers instead of being locked to OpenAI only.
## Key Changes Made
### 1. Core Infrastructure
#### New LLM Factory (`tradingagents/llm_factory.py`)
- Unified interface for creating LLM instances from any provider
- Automatic handling of provider-specific initialization
- Supports 9+ providers out of the box
- Clear error messages for missing dependencies
#### Updated Configuration (`tradingagents/default_config.py`)
- Added `llm_provider` setting (default: "openai")
- Added `temperature` for model control
- Added `llm_kwargs` for provider-specific parameters
- Includes example configurations for all providers
### 2. Code Refactoring
#### `tradingagents/graph/trading_graph.py`
- Removed hardcoded provider checks
- Uses LLM factory for initialization
- Cleaner, more maintainable code
#### Type Annotations Updated
- `tradingagents/graph/setup.py`
- `tradingagents/graph/signal_processing.py`
- `tradingagents/graph/reflection.py`
- Now accept any LangChain-compatible LLM (not just ChatOpenAI)
### 3. Dependencies
#### `requirements.txt`
- Organized by purpose with comments
- Includes langchain-core and langchain-community
- Optional packages documented for each provider
#### `.env.example`

# ✅ Migration Complete - Multi-Provider AI Support Verified
## Test Results
### ✅ All Tests Passed!
The migration to support multiple AI providers (including Ollama) is **complete and working**.
**Test Results:**
```
Test 1: Importing LLM Factory... ✅
Test 2: Importing default config... ✅
Test 3: Creating Ollama configuration... ✅
Test 4: Checking langchain-community package... ✅
Test 5: Creating Ollama LLM instance... ✅
Test 6: Testing LLM with simple query... ✅
Test 7: Creating TradingAgentsGraph with Ollama... ✅
```
## What Was Fixed
### Issue Found
The `memory.py` module was hardcoded to use OpenAI's API, causing errors when using Ollama.
### Solution Applied
Updated `tradingagents/agents/utils/memory.py` to be provider-agnostic:
1. **Detect Provider**: Checks config for `llm_provider` setting
2. **Conditional Client Creation**: Only creates OpenAI client when needed
3. **Flexible Embeddings**:
- Uses OpenAI embeddings for OpenAI provider
- Uses ChromaDB's default embeddings for Ollama
4. **Graceful Handling**: Works with or without custom embeddings
## How to Use
### Quick Test
Run the included test script:
```bash
python test_ollama.py
```
### Full Example
Run a complete trading analysis with Ollama:
```bash
python example_ollama.py
```
### In Your Code
```python
from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.default_config import DEFAULT_CONFIG
# Configure for Ollama
config = DEFAULT_CONFIG.copy()
config["llm_provider"] = "ollama"
config["deep_think_llm"] = "llama3"
config["quick_think_llm"] = "llama3"
config["backend_url"] = "http://localhost:11434"
# Create graph
ta = TradingAgentsGraph(config=config, debug=True)
# Run analysis
_, decision = ta.propagate("AAPL", "2024-05-10")
print(decision)
```

### Implementation Details
We built TradingAgents with LangGraph to ensure flexibility and modularity. We utilize `o1-preview` and `gpt-4o` as our deep thinking and fast thinking LLMs for our experiments. However, for testing purposes, we recommend you use `o4-mini` and `gpt-4.1-mini` to save on costs as our framework makes **lots of** API calls.
We built TradingAgents with LangGraph to ensure flexibility and modularity. The framework now supports **multiple LLM providers** through a unified interface, giving you the freedom to choose based on your needs:
- **For Production/Quality**: We recommend `o1-preview` and `gpt-4o` (OpenAI) or `claude-3-opus` (Anthropic)
- **For Cost-Effective Testing**: Use `o4-mini` and `gpt-4o-mini` (OpenAI) or `gemini-1.5-flash` (Google)
- **For FREE Local Inference**: Use Ollama with `llama3.2` or `mistral-nemo` models
- **For Speed**: Use Groq with `mixtral-8x7b-32768` or `llama3-8b-8192`
The framework makes **lots of** API calls, so choosing the right provider for your use case can significantly impact costs and performance.
📚 **See [LLM Provider Guide](docs/LLM_PROVIDER_GUIDE.md)** for detailed recommendations and setup instructions for all providers.
### Python Usage
To use TradingAgents inside your code, you can import the `tradingagents` module and initialize a `TradingAgentsGraph()` object. The `.propagate()` function will return a decision. You can run `main.py`, here's also a quick example:

For production use or if you encounter rate limits, consider upgrading to [Alpha Vantage Premium](https://www.alphavantage.co/premium/) for more stable and reliable data access. For offline experimentation, there's a local data vendor option that uses our **Tauric TradingDB**, a curated dataset for backtesting, though this is still in development. We're currently refining this dataset and plan to release it soon alongside our upcoming projects. Stay tuned!

# Updated README Sections
## Section to Replace "Required APIs"
Replace the "Required APIs" section in README.md with this:
---
### Required APIs
#### Data APIs
You will need [Alpha Vantage API](https://www.alphavantage.co/support/#api-key) for fundamental and news data (default configuration).
```bash
export ALPHA_VANTAGE_API_KEY=$YOUR_ALPHA_VANTAGE_API_KEY
```
**Note:** We are happy to partner with Alpha Vantage to provide robust API support for TradingAgents. You can get a free AlphaVantage API [here](https://www.alphavantage.co/support/#api-key), TradingAgents-sourced requests also have increased rate limits to 60 requests per minute with no daily limits. Typically the quota is sufficient for performing complex tasks with TradingAgents thanks to Alpha Vantage's open-source support program. If you prefer to use OpenAI for these data sources instead, you can modify the data vendor settings in `tradingagents/default_config.py`.
#### LLM Provider APIs
🎉 **NEW: Multi-Provider AI Support!** TradingAgents now supports multiple AI/LLM providers:
- ✅ **OpenAI** (GPT-4, GPT-4o, GPT-3.5-turbo) - Default
- ✅ **Ollama** (Local models - **FREE!** Llama 3.2, Mistral, etc.)
- ✅ **Anthropic** (Claude 3 Opus, Sonnet, Haiku)
- ✅ **Google** (Gemini Pro, Gemini Flash)
- ✅ **Groq** (Fast inference)
- ✅ **OpenRouter** (Multi-provider access)
- ✅ **Azure OpenAI**, **Together AI**, **HuggingFace**
**For OpenAI (Default):**
```bash
export OPENAI_API_KEY=$YOUR_OPENAI_API_KEY
```
**For Ollama (Free & Local):**
```bash
# No API key needed! Just install Ollama and pull models
ollama pull llama3.2 # Recommended - supports tool calling
```
**For Other Providers:**
```bash
# Anthropic
export ANTHROPIC_API_KEY=sk-ant-your-key-here
# Google Gemini
export GOOGLE_API_KEY=your-google-key-here
# Groq
export GROQ_API_KEY=gsk-your-groq-key
# See docs/LLM_PROVIDER_GUIDE.md for complete setup
```
Alternatively, you can create a `.env` file in the project root with your API keys (see `.env.example` for reference):
```bash
cp .env.example .env
# Edit .env with your actual API keys
```

## Usage in Code
### Using Default Configuration
```python
from tradingagents.graph.trading_graph import TradingAgentsGraph
# Uses default config from tradingagents/default_config.py
graph = TradingAgentsGraph()
```
### Using Custom Configuration
```python
from tradingagents.graph.trading_graph import TradingAgentsGraph
# Custom config for Ollama
custom_config = {
"llm_provider": "ollama",
"deep_think_llm": "llama3:70b",
"quick_think_llm": "llama3:8b",
"backend_url": "http://localhost:11434",
"temperature": 0.7,
# ... other config options
}
graph = TradingAgentsGraph(config=custom_config)
```
### Programmatically Creating LLM Instances
```python
from tradingagents.llm_factory import LLMFactory, get_llm_instance
# Method 1: Direct factory usage
llm = LLMFactory.create_llm(
provider="ollama",
model="llama3",
base_url="http://localhost:11434",
temperature=0.7
)
# Method 2: Using config dictionary
config = {
"llm_provider": "anthropic",
"quick_think_llm": "claude-3-haiku-20240307",
"temperature": 0.7,
}
llm = get_llm_instance(config, model_type="quick_think")
```
## Advanced Configuration
### Additional LLM Parameters
You can pass additional provider-specific parameters via `llm_kwargs`:
```python
config = {
"llm_provider": "openai",
"deep_think_llm": "gpt-4o",
"quick_think_llm": "gpt-4o-mini",
"temperature": 0.7,
"llm_kwargs": {
"max_tokens": 4096,
"top_p": 0.9,
"frequency_penalty": 0.0,
"presence_penalty": 0.0,
}
}
```
### Model Recommendations by Use Case
#### Best for Cost Efficiency
- **Deep Think:** Ollama Llama 3 70B (local, free)
- **Quick Think:** Ollama Llama 3 8B (local, free)
#### Best for Quality
- **Deep Think:** GPT-4o or Claude 3 Opus
- **Quick Think:** GPT-4o-mini or Claude 3 Haiku
#### Best for Speed
- **Deep Think:** Groq Mixtral 8x7B
- **Quick Think:** Groq Llama 3 8B
#### Best for Privacy
- **Deep Think:** Ollama Llama 3 70B (local)
- **Quick Think:** Ollama Llama 3 8B (local)
## Troubleshooting
### Import Errors
If you get import errors for a specific provider:
```bash
pip install langchain-[provider]
```
For example:
```bash
pip install langchain-anthropic # For Anthropic
pip install langchain-community # For Ollama
pip install langchain-groq # For Groq
```
### API Key Issues
Make sure your environment variables are set correctly:
```bash
# Check if set
echo $OPENAI_API_KEY
# Set temporarily
export OPENAI_API_KEY=your-key
# Set permanently (add to ~/.bashrc or ~/.zshrc)
echo 'export OPENAI_API_KEY=your-key' >> ~/.bashrc
```
### Ollama Connection Issues
If Ollama fails to connect:
1. Check if Ollama is running: `ollama list`
2. Verify the endpoint: Default is `http://localhost:11434`
3. Try pulling the model: `ollama pull llama3`
### Model Not Found
Make sure you're using the correct model identifier for each provider:
- OpenAI: `gpt-4o`, `gpt-4o-mini`, `gpt-3.5-turbo`
- Anthropic: `claude-3-opus-20240229`, `claude-3-sonnet-20240229`, `claude-3-haiku-20240307`
- Google: `gemini-1.5-pro`, `gemini-1.5-flash`
- Ollama: `llama3`, `llama3:70b`, `mistral`, etc.
## Migration from OpenAI-Only Version
If you're upgrading from an older version that only supported OpenAI:
1. The default configuration still uses OpenAI, so existing code will work
2. To switch providers, update your config:
```python
config["llm_provider"] = "ollama" # or "anthropic", "google", etc.
config["deep_think_llm"] = "llama3:70b"
config["quick_think_llm"] = "llama3:8b"
config["backend_url"] = "http://localhost:11434"
```
3. Install required packages for your chosen provider
4. Set appropriate environment variables
## Contributing
To add support for a new provider:
1. Edit `tradingagents/llm_factory.py`
2. Add a new `_create_[provider]_llm()` method
3. Update the `create_llm()` method to handle the new provider
4. Update this documentation
5. Submit a pull request

- Supports: OpenAI, Ollama, Anthropic, Google, Azure, Groq, Together AI, HuggingFace, OpenRouter
### 2. Updated Configuration
**File:** `tradingagents/default_config.py`
Enhanced configuration with:
- `llm_provider`: Specify which provider to use
- `temperature`: Control model randomness
- `llm_kwargs`: Pass additional provider-specific parameters
- Example configurations for all providers (commented)
### 3. Refactored Graph Initialization
**File:** `tradingagents/graph/trading_graph.py`
- Removed hardcoded provider checks (OpenAI, Anthropic, Google)
- Now uses the LLM factory for provider-agnostic initialization
- Simplified code with automatic provider handling
### 4. Type Annotation Updates
**Files:**
- `tradingagents/graph/setup.py`
- `tradingagents/graph/signal_processing.py`
- `tradingagents/graph/reflection.py`
- Removed specific type hints (e.g., `ChatOpenAI`)
- Now accept any LangChain-compatible LLM
- Maintains full functionality while being provider-agnostic
### 5. Updated Dependencies
**File:** `requirements.txt`
- Organized dependencies by purpose
- Added comments for optional provider packages
- Included langchain-core and langchain-community
- Documented which packages are needed for each provider
### 6. Environment Variables
**File:** `.env.example`
- Added examples for all supported providers
- Documented which API keys are needed for each
- Included Ollama configuration (no API key needed)

## Migration Steps
### For Existing Users (Currently Using OpenAI)
**No changes required!** The default configuration still uses OpenAI. Your existing code will work as-is.
### To Switch to a Different Provider
#### Option 1: Using Ollama (Free, Local)
```python
from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.default_config import DEFAULT_CONFIG
config = DEFAULT_CONFIG.copy()
config["llm_provider"] = "ollama"
config["deep_think_llm"] = "llama3:70b"
config["quick_think_llm"] = "llama3:8b"
config["backend_url"] = "http://localhost:11434"
ta = TradingAgentsGraph(config=config)
```
**Setup:**
1. Install Ollama: https://ollama.ai
2. Pull models: `ollama pull llama3`
3. Install langchain-community: `pip install langchain-community`
#### Option 2: Using Anthropic Claude
```python
config = DEFAULT_CONFIG.copy()
config["llm_provider"] = "anthropic"
config["deep_think_llm"] = "claude-3-opus-20240229"
config["quick_think_llm"] = "claude-3-haiku-20240307"
ta = TradingAgentsGraph(config=config)
```
**Setup:**
1. Get API key from https://console.anthropic.com/
2. Set environment: `export ANTHROPIC_API_KEY=your-key`
3. Install: `pip install langchain-anthropic`
#### Option 3: Using Google Gemini
```python
config = DEFAULT_CONFIG.copy()
config["llm_provider"] = "google"
config["deep_think_llm"] = "gemini-1.5-pro"
config["quick_think_llm"] = "gemini-1.5-flash"
ta = TradingAgentsGraph(config=config)
```
**Setup:**
1. Get API key from https://makersuite.google.com/app/apikey
2. Set environment: `export GOOGLE_API_KEY=your-key`
3. Install: `pip install langchain-google-genai` (already in requirements.txt)
## Benefits
### 1. **Cost Savings**
- Use free local models with Ollama (Llama 3, Mistral, etc.)
- Choose cheaper providers like Groq for specific tasks
- Mix and match: expensive models for complex tasks, cheap for simple ones
### 2. **Privacy**
- Run models locally with Ollama
- No data sent to external APIs
- Full control over your data
### 3. **Performance**
- Use Groq for ultra-fast inference
- Choose the best model for each task
- Experiment with different providers
### 4. **Flexibility**
- Not locked to a single vendor
- Easy to switch providers
- Test multiple providers simultaneously
### 5. **Future-Proof**
- Easy to add new providers
- Stay up-to-date with latest models
- Adapt to changing AI landscape
## Breaking Changes
**None!** This update is fully backward compatible. Existing code using OpenAI will continue to work without modifications.
## Testing
To test different providers:
```python
from tradingagents.llm_factory import LLMFactory
# Test provider creation
openai_llm = LLMFactory.create_llm(
provider="openai",
model="gpt-4o-mini",
temperature=0.7
)
ollama_llm = LLMFactory.create_llm(
provider="ollama",
model="llama3",
base_url="http://localhost:11434",
temperature=0.7
)
# Verify it works
response = openai_llm.invoke("Hello, how are you?")
print(response.content)
```
## Troubleshooting
### Import Errors
If you get `ImportError` for a provider:
```bash
# For Ollama
pip install langchain-community
# For Groq
pip install langchain-groq
# For Together AI
pip install langchain-together
```
### API Key Not Found
Make sure environment variables are set:
```bash
# Check
echo $OPENAI_API_KEY
# Set
export OPENAI_API_KEY=your-key
# Or add to .env file
echo "OPENAI_API_KEY=your-key" >> .env
```
### Ollama Connection Failed
1. Make sure Ollama is running: `ollama serve`
2. Check if model is available: `ollama list`
3. Pull model if needed: `ollama pull llama3`
4. Verify endpoint: default is `http://localhost:11434`
## Support
For detailed provider setup and configuration:
- See `docs/LLM_PROVIDER_GUIDE.md`
- See `docs/MULTI_PROVIDER_SUPPORT.md`
- Check example configs in `examples/llm_provider_configs.py`
## Future Enhancements
Potential future additions:
- Support for more providers (Cohere, AI21, etc.)
- Automatic provider fallback
- Cost tracking per provider
- Performance benchmarking
- Provider-specific optimizations

# README Addition - Multi-Provider AI Support
**Add this section to your README.md after the "Required APIs" section:**
---
## 🚀 NEW: Multi-Provider AI Support
TradingAgents now supports multiple AI/LLM providers! You're no longer limited to OpenAI.
**Supported Providers:**
- ✅ **OpenAI** (GPT-4, GPT-4o, GPT-3.5-turbo)
- ✅ **Ollama** (Local models - FREE! Llama 3, Mistral, Mixtral, etc.)
- ✅ **Anthropic** (Claude 3 Opus, Sonnet, Haiku)
- ✅ **Google** (Gemini Pro, Gemini Flash)
- ✅ **Groq** (Fast inference)
- ✅ **OpenRouter** (Multi-provider access)
- ✅ **Azure OpenAI**
- ✅ **Together AI**
- ✅ **HuggingFace**
📚 **[See Full Provider Guide](docs/LLM_PROVIDER_GUIDE.md)** | **[Quick Start Examples](docs/MULTI_PROVIDER_SUPPORT.md)**
### Quick Examples
**OpenAI (Default - No Changes Needed):**
```python
from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.default_config import DEFAULT_CONFIG
ta = TradingAgentsGraph(config=DEFAULT_CONFIG)
_, decision = ta.propagate("NVDA", "2024-05-10")
```
**Ollama (Local & Free):**
```python
config = DEFAULT_CONFIG.copy()
config.update({
"llm_provider": "ollama",
"deep_think_llm": "llama3:70b",
"quick_think_llm": "llama3:8b",
"backend_url": "http://localhost:11434"
})
ta = TradingAgentsGraph(config=config)
```
**Anthropic Claude:**
```python
config = DEFAULT_CONFIG.copy()
config.update({
"llm_provider": "anthropic",
"deep_think_llm": "claude-3-opus-20240229",
"quick_think_llm": "claude-3-haiku-20240307"
})
ta = TradingAgentsGraph(config=config)
```
**Google Gemini:**
```python
config = DEFAULT_CONFIG.copy()
config.update({
"llm_provider": "google",
"deep_think_llm": "gemini-1.5-pro",
"quick_think_llm": "gemini-1.5-flash"
})
ta = TradingAgentsGraph(config=config)
```
**Groq (Fast & Affordable):**
```python
config = DEFAULT_CONFIG.copy()
config.update({
"llm_provider": "groq",
"deep_think_llm": "mixtral-8x7b-32768",
"quick_think_llm": "llama3-8b-8192"
})
ta = TradingAgentsGraph(config=config)
```
See `examples/llm_provider_configs.py` for more pre-configured options!
---
**Then update the "Implementation Details" section to say:**
We built TradingAgents with LangGraph to ensure flexibility and modularity. The system now supports multiple LLM providers through a unified interface. You can use OpenAI (default), Ollama for local/free models, Anthropic Claude, Google Gemini, Groq, and others.
For OpenAI, we recommend using `o4-mini` and `gpt-4o-mini` for cost-effective testing, as our framework makes **lots of** API calls. For production, consider `o1-preview` and `gpt-4o`.
For free local inference, use Ollama with Llama 3 models. For the best quality, use Claude 3 Opus or GPT-4o. For the fastest inference, use Groq.
See the [LLM Provider Guide](docs/LLM_PROVIDER_GUIDE.md) for detailed recommendations and setup instructions.
