+# Configuring Ollama Provider in G3
+
+This guide shows you how to configure G3 to use Ollama as your LLM provider.
+
+## Quick Start
+
+### 1. Install Ollama
+
+```bash
+# Visit https://ollama.ai to download and install
+# Or use curl:
+curl https://ollama.ai/install.sh | sh
+```
+
+### 2. Pull a Model
+
+```bash
+ollama pull llama3.2
+# or any other model you prefer
+```
+
+### 3. Create Configuration File
+
+Copy the example configuration:
+
+```bash
+cp config.ollama.example.toml ~/.config/g3/config.toml
+```
+
+Or create it manually:
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+```
+
+### 4. Run G3
+
+```bash
+g3
+# G3 will now use Ollama with llama3.2!
+```
+
+## Configuration Options
+
+### Basic Configuration
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+```
+
+This is the minimal configuration needed. It uses all defaults:
+- Base URL: `http://localhost:11434`
+- Temperature: `0.7`
+- Max tokens: Not limited (uses model default)
+
+### Full Configuration
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+base_url = "http://localhost:11434"
+max_tokens = 2048
+temperature = 0.7
+```
+
+### Custom Ollama Host
+
+If you're running Ollama on a different machine or port:
+
+```toml
+[providers.ollama]
+model = "llama3.2"
+base_url = "http://192.168.1.100:11434"
+```
+
+### Different Models
+
+You can use any Ollama model:
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"  # Alibaba's Qwen model
+```
+
+```toml
+[providers.ollama]
+model = "mistral"  # Mistral AI
+```
+
+```toml
+[providers.ollama]
+model = "llama3.1:70b"  # Larger Llama model
+```
+
+## Multiple Provider Configuration
+
+You can configure multiple providers and switch between them:
+
+```toml
+[providers]
+default_provider = "ollama"  # Default for most operations
+
+# Ollama for local, fast responses
+[providers.ollama]
+model = "llama3.2:3b"
+temperature = 0.7
+
+# Databricks for more complex tasks
+[providers.databricks]
+host = "https://your-workspace.cloud.databricks.com"
+model = "databricks-claude-sonnet-4"
+max_tokens = 4096
+temperature = 0.1
+use_oauth = true
+```
+
+Then switch providers with:
+
+```bash
+g3 --provider databricks
+```
+
+## Autonomous Mode (Coach-Player)
+
+Use different providers for code review (coach) and implementation (player):
+
+```toml
+[providers]
+default_provider = "ollama"
+coach = "databricks"  # Use powerful cloud model for review
+player = "ollama"     # Use local model for implementation
+
+[providers.ollama]
+model = "qwen2.5:14b"  # Larger local model for coding
+
+[providers.databricks]
+host = "https://your-workspace.cloud.databricks.com"
+model = "databricks-claude-sonnet-4"
+use_oauth = true
+```
+
+This gives you the best of both worlds:
+- Fast local execution for coding tasks
+- Powerful cloud review for quality assurance
+
+## Recommended Models
+
+### For Coding Tasks
+
+| Model | Size | Speed | Quality | Notes |
+|-------|------|-------|---------|-------|
+| **qwen2.5:7b** | 7B | Fast | Excellent | Best balance for coding |
+| **llama3.2:3b** | 3B | Very Fast | Good | Great for quick tasks |
+| **llama3.1:8b** | 8B | Medium | Very Good | Solid all-rounder |
+| **mistral** | 7B | Fast | Good | Good for general use |
+
+### For Complex Tasks
+
+| Model | Size | Speed | Quality | Notes |
+|-------|------|-------|---------|-------|
+| **qwen2.5:14b** | 14B | Medium | Excellent | Best local model for coding |
+| **qwen2.5:32b** | 32B | Slow | Outstanding | If you have the resources |
+| **llama3.1:70b** | 70B | Very Slow | Outstanding | Requires significant RAM/GPU |
+
+## Temperature Settings
+
+Temperature controls randomness in responses:
+
+- **0.1-0.3**: Deterministic, good for code generation
+- **0.5-0.7**: Balanced, good for most tasks
+- **0.8-1.0**: Creative, good for brainstorming
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"
+temperature = 0.2  # Focused code generation
+```
+
+## Max Tokens
+
+Control response length:
+
+```toml
+[providers.ollama]
+model = "llama3.2"
+max_tokens = 1024  # Shorter responses
+```
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"
+max_tokens = 4096  # Longer, detailed responses
+```
+
+Leave it unset for model defaults (recommended).
+
+## Performance Tuning
+
+### GPU Acceleration
+
+Ollama automatically uses GPU if available. To check:
+
+```bash
+ollama ps
+```
+
+### Quantized Models
+
+For faster responses with less RAM:
+
+```toml
+[providers.ollama]
+model = "llama3.2:3b-q4_0"  # 4-bit quantization
+```
+
+Quantization options:
+- `q4_0`: 4-bit, fastest, lowest quality
+- `q5_0`: 5-bit, balanced
+- `q8_0`: 8-bit, slower, better quality
+
+### Multiple Models
+
+You can pull multiple models and switch easily:
+
+```bash
+ollama pull llama3.2:3b    # Fast for chat
+ollama pull qwen2.5:7b     # Better for code
+ollama pull mistral        # General purpose
+```
+
+Then change your config:
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"  # Just change this line
+```
+
+## Troubleshooting
+
+### Ollama Not Running
+
+```bash
+# Check if Ollama is running
+curl http://localhost:11434/api/version
+
+# Start Ollama (macOS/Linux)
+ollama serve
+
+# Or just run a model (auto-starts)
+ollama run llama3.2
+```
+
+### Model Not Found
+
+```bash
+# List available models
+ollama list
+
+# Pull the model
+ollama pull llama3.2
+```
+
+### Slow Responses
+
+1. Use a smaller model:
+   ```toml
+   model = "llama3.2:1b"  # Smallest, fastest
+   ```
+
+2. Use quantized version:
+   ```toml
+   model = "llama3.2:3b-q4_0"
+   ```
+
+3. Reduce max_tokens:
+   ```toml
+   max_tokens = 512
+   ```
+
+### Out of Memory
+
+1. Switch to smaller model
+2. Use quantized version
+3. Close other applications
+4. Check GPU memory: `ollama ps`
+
+### Connection Refused
+
+Check base_url is correct:
+
+```toml
+[providers.ollama]
+model = "llama3.2"
+base_url = "http://localhost:11434"  # Default
+```
+
+For remote Ollama:
+
+```toml
+base_url = "http://your-server:11434"
+```
+
+## Complete Example Configs
+
+### Minimal Local Setup
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+
+[agent]
+max_context_length = 8192
+enable_streaming = true
+timeout_seconds = 60
+```
+
+### Optimized for Coding
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "qwen2.5:7b"
+temperature = 0.2
+max_tokens = 2048
+
+[agent]
+max_context_length = 16384
+enable_streaming = true
+timeout_seconds = 120
+```
+
+### Fast Responses
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2:3b-q4_0"
+temperature = 0.7
+max_tokens = 1024
+
+[agent]
+max_context_length = 4096
+enable_streaming = true
+timeout_seconds = 30
+```
+
+### High Quality (Requires Good Hardware)
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "qwen2.5:32b"
+temperature = 0.3
+max_tokens = 4096
+
+[agent]
+max_context_length = 32768
+enable_streaming = true
+timeout_seconds = 300
+```
+
+### Hybrid (Local + Cloud)
+
+```toml
+[providers]
+default_provider = "ollama"
+coach = "databricks"
+player = "ollama"
+
+[providers.ollama]
+model = "qwen2.5:14b"
+temperature = 0.2
+
+[providers.databricks]
+host = "https://your-workspace.cloud.databricks.com"
+model = "databricks-claude-sonnet-4"
+use_oauth = true
+
+[agent]
+max_context_length = 16384
+enable_streaming = true
+timeout_seconds = 120
+```
+
+## Environment Variables
+
+You can override config with environment variables:
+
+```bash
+# Override model
+G3_PROVIDERS_OLLAMA_MODEL=qwen2.5:7b g3
+
+# Override base URL
+G3_PROVIDERS_OLLAMA_BASE_URL=http://192.168.1.100:11434 g3
+
+# Override default provider
+G3_PROVIDERS_DEFAULT_PROVIDER=ollama g3
+```
+
+## Best Practices
+
+1. **Start Small**: Begin with llama3.2:3b, scale up if needed
+2. **Use Quantization**: q4_0 or q5_0 for best speed/quality balance
+3. **Match Task to Model**: 
+   - Quick edits: 1B-3B models
+   - Code generation: 7B-14B models
+   - Complex refactoring: 14B-32B models
+4. **Temperature for Code**: Use 0.1-0.3 for deterministic output
+5. **Enable Streaming**: Always enable for better UX
+6. **Local First**: Use Ollama by default, cloud for special cases
+

+    let provider = OllamaProvider::new(
+        "llama3.2".to_string(),
+        None,  // base_url: defaults to http://localhost:11434
+        None,  // max_tokens: optional
+        None,  // temperature: defaults to 0.7
+    )?;
+
+    // Create a simple request
+    let request = CompletionRequest {
+        messages: vec![
+            Message {
+                role: MessageRole::User,
+                content: "What is the capital of France?".to_string(),
+            },
+        ],
+        max_tokens: Some(1000),
+        temperature: Some(0.7),
+        stream: false,
+        tools: None,
+    };
+
+    // Get completion
+    let response = provider.complete(request).await?;
+    println!("Response: {}", response.content);
+    println!("Tokens: {}", response.usage.total_tokens);
+
+    Ok(())
+}
+```
+
+### Streaming Example
+
+```rust
+use futures_util::StreamExt;
+
+let request = CompletionRequest {
+    messages: vec![
+        Message {
+            role: MessageRole::User,
+            content: "Write a short poem about coding".to_string(),
+        },
+    ],
+    max_tokens: Some(500),
+    temperature: Some(0.8),
+    stream: true,
+    tools: None,
+};
+
+let mut stream = provider.stream(request).await?;
+
+while let Some(chunk_result) = stream.next().await {
+    match chunk_result {
+        Ok(chunk) => {
+            print!("{}", chunk.content);
+            if chunk.finished {
+                println!("\n\nDone!");
+                if let Some(usage) = chunk.usage {
+                    println!("Total tokens: {}", usage.total_tokens);
+                }
+            }
+        }
+        Err(e) => eprintln!("Error: {}", e),
+    }
+}
+```
+
+### Tool Calling Example
+
+```rust
+use serde_json::json;
+
+let tools = vec![Tool {
+    name: "get_weather".to_string(),
+    description: "Get current weather for a location".to_string(),
+    input_schema: json!({
+        "type": "object",
+        "properties": {
+            "location": {
+                "type": "string",
+                "description": "City name"
+            },
+            "unit": {
+                "type": "string",
+                "enum": ["celsius", "fahrenheit"],
+                "description": "Temperature unit"
+            }
+        },
+        "required": ["location"]
+    }),
+}];
+
+let request = CompletionRequest {
+    messages: vec![
+        Message {
+            role: MessageRole::User,
+            content: "What's the weather in Paris?".to_string(),
+        },
+    ],
+    max_tokens: Some(500),
+    temperature: Some(0.5),
+    stream: false,
+    tools: Some(tools),
+};
+
+let response = provider.complete(request).await?;
+println!("Response: {}", response.content);
+```
+
+### Custom Ollama Host
+
+```rust
+// Connect to remote Ollama instance
+let provider = OllamaProvider::new(
+    "llama3.2".to_string(),
+    Some("http://192.168.1.100:11434".to_string()),
+    None,
+    None,
+)?;
+```
+
+### Fetch Available Models
+
+```rust
+// Discover what models are available
+let models = provider.fetch_available_models().await?;
+println!("Available models:");
+for model in models {
+    println!("  - {}", model);
+}
+```
+
+## Supported Models
+
+The provider works with any Ollama model, including:
+
+- **llama3.2** (1B, 3B) - Meta's latest Llama models
+- **llama3.1** (8B, 70B, 405B) - Previous generation
+- **qwen2.5** (7B, 14B, 32B) - Alibaba's Qwen models  
+- **mistral** - Mistral AI models
+- **mixtral** - Mixture of experts model
+- **phi3** - Microsoft's Phi-3
+- **gemma2** - Google's Gemma 2
+
+## Configuration
+
+### Constructor Parameters
+
+```rust
+OllamaProvider::new(
+    model: String,           // Model name (e.g., "llama3.2")
+    base_url: Option<String>, // Ollama API URL (default: http://localhost:11434)
+    max_tokens: Option<u32>,  // Maximum tokens to generate (optional)
+    temperature: Option<f32>, // Sampling temperature (default: 0.7)
+)
+```
+
+### Request Options
+
+```rust
+CompletionRequest {
+    messages: Vec<Message>,      // Conversation history
+    max_tokens: Option<u32>,     // Override provider's max_tokens
+    temperature: Option<f32>,    // Override provider's temperature
+    stream: bool,                // Enable streaming responses
+    tools: Option<Vec<Tool>>,    // Tools for function calling
+}
+```
+
+## Comparison with Other Providers
+
+| Feature | Ollama | OpenAI | Anthropic | Databricks |
+|---------|--------|--------|-----------|------------|
+| Local Execution | ✅ | ❌ | ❌ | ❌ |
+| Authentication | None | API Key | API Key | OAuth/Token |
+| Tool Calling | ✅ | ✅ | ✅ | ✅ |
+| Streaming | ✅ | ✅ | ✅ | ✅ |
+| Cost | Free | Paid | Paid | Paid |
+| Privacy | High | Low | Low | Medium |
+
+## Implementation Details
+
+### API Endpoints
+
+- **Chat Completion**: `POST /api/chat`
+- **Model List**: `GET /api/tags`
+
+### Response Format
+
+Ollama uses a simple JSON-per-line streaming format:
+
+```json
+{"message":{"role":"assistant","content":"Hello"},"done":false}
+{"message":{"role":"assistant","content":" there"},"done":false}
+{"done":true,"prompt_eval_count":10,"eval_count":20}
+```
+
+### Tool Call Format
+
+Tool calls are returned in the message structure:
+
+```json
+{
+  "message": {
+    "role": "assistant",
+    "content": "",
+    "tool_calls": [
+      {
+        "function": {
+          "name": "get_weather",
+          "arguments": {"location": "Paris", "unit": "celsius"}
+        }
+      }
+    ]
+  },
+  "done": true
+}
+```
+
+## Troubleshooting
+
+### Connection Errors
+
+If you see connection errors, ensure Ollama is running:
+
+```bash
+# Check if Ollama is running
+curl http://localhost:11434/api/version
+
+# Start Ollama (if needed)
+ollama serve
+```
+
+### Model Not Found
+
+Pull the model first:
+
+```bash
+ollama pull llama3.2
+ollama list  # Check available models
+```
+
+### Performance Issues
+
+- Use smaller models (1B, 3B) for faster responses
+- Reduce `max_tokens` to limit generation length
+- Enable GPU acceleration if available
+- Consider quantized models (e.g., `llama3.2:3b-q4_0`)
+
+## Testing
+
+Run the included tests:
+
+```bash
+cargo test --package g3-providers ollama
+```
+
+All tests should pass:
+```
+running 4 tests
+test ollama::tests::test_custom_base_url ... ok
+test ollama::tests::test_message_conversion ... ok
+test ollama::tests::test_provider_creation ... ok
+test ollama::tests::test_tool_conversion ... ok
+```
+
+## Architecture
+
+The provider follows the same architecture as other g3 providers:
+
+1. **OllamaProvider**: Main struct implementing `LLMProvider` trait
+2. **Request/Response Structures**: Internal types for Ollama API
+3. **Streaming Parser**: Handles line-by-line JSON parsing
+4. **Tool Call Handling**: Accumulates and converts tool calls
+5. **Error Handling**: Robust error handling with retries
+
+## Contributing
+
+The provider is part of the g3-providers crate. To contribute:
+
+1. Add features to `ollama.rs`
+2. Update tests
+3. Run `cargo test --package g3-providers`
+4. Update this documentation

+//! Ollama LLM provider implementation for the g3-providers crate.
+//!
+//! This module provides an implementation of the `LLMProvider` trait for Ollama,
+//! supporting both completion and streaming modes with native tool calling.
+//!
+//! # Features
+//!
+//! - Support for any Ollama model (llama3.2, mistral, qwen, etc.)
+//! - Both completion and streaming response modes
+//! - Native tool calling support for compatible models
+//! - Configurable base URL (defaults to http://localhost:11434)
+//! - Simple configuration with no authentication required
+//!
+//! # Usage
+//!
+//! ```rust,no_run
+//! use g3_providers::{OllamaProvider, LLMProvider, CompletionRequest, Message, MessageRole};
+//!
+//! #[tokio::main]
+//! async fn main() -> anyhow::Result<()> {
+//!     // Create the provider with default settings (localhost:11434)
