-
-### Example `.env` file
+### For the Core Modaletta Package
 
 ```bash
-# For Letta Cloud
-LETTA_SERVER_URL=https://api.letta.com
-LETTA_API_KEY=your_letta_api_key_here
-
-# For self-hosted Letta
-# LETTA_SERVER_URL=http://localhost:8283
-# LETTA_API_KEY=  # Optional for self-hosted
-
-# Model configuration
-MODALETTA_LLM_MODEL=openai/gpt-4.1
-MODALETTA_EMBEDDING_MODEL=openai/text-embedding-3-small
-MODALETTA_TOOLS=web_search,run_code
-
-# Optional Modal configuration (only needed for serverless deployment)
-# MODAL_TOKEN_ID=your_modal_token_id
-# MODAL_TOKEN_SECRET=your_modal_token_secret
-
-# Optional: E2B API key for run_code tool (get free key at https://e2b.dev)
-# E2B_API_KEY=your_e2b_api_key
-```
+cd modaletta
 
-2. **Verify basic functionality**:
+# Create virtual environment (recommended)
+python -m venv .venv && source .venv/bin/activate
 
-```bash
+# Install and use
+pip install -e .
 modaletta --help
-modaletta config-info
-```
-
-3. **Create and use an agent**:
-
-```bash
-# Create an agent with custom persona
-modaletta create-agent \
-  --name "my-assistant" \
-  --persona "I am a helpful AI assistant specializing in Python development." \
-  --human "The user is a Python developer."
-
-# List all agents
-modaletta list-agents
-
-# Send a message (use the agent ID from list-agents)
-modaletta send-message <agent-id> "Hello! Can you help me debug some Python code?"
-
-# Send with streaming (see response as it's generated)
-modaletta send-message --stream <agent-id> "Tell me a story about AI."
-
-# View agent memory
-modaletta get-memory <agent-id>
-```
-
-
-
-**Note**: The `run_code` tool requires an E2B API key for self-hosted servers. It works automatically on Letta Cloud. Get a free key at [e2b.dev](https://e2b.dev).
-
-## Python API
-
-### Quick Start
-
-```python
-from modaletta import ModalettaAgent, ModalettaClient, ModalettaConfig
-
-# Configure (loads from environment variables)
-config = ModalettaConfig.from_env()
-config.tools = ["web_search", "run_code"]  # Add built-in tools
-
-# Option 1: Use the client directly
-client = ModalettaClient(config)
-agent_id = client.create_agent(
-    name="my-assistant",
-    persona="I am a helpful AI assistant that specializes in coding and research.",
-    human="The user is a Python developer working on AI projects."
-)
-
-# Send a message (note: Letta agents are STATEFUL, only send new messages)
-response = client.send_message(agent_id, "Hello! Can you help me with Python?")
-
-# Process response with proper message_type handling
-for msg in response:
-    message_type = msg.get("message_type", "")
-    if message_type == "assistant_message":
-        print(f"Assistant: {msg.get('content', '')}")
-    elif message_type == "tool_call_message":
-        tool_call = msg.get("tool_call", {})
-        print(f"[Calling tool: {tool_call.get('name', '')}]")
-    elif message_type == "tool_return_message":
-        print(f"[Tool result: {msg.get('tool_return', '')}]")
-
-# Option 2: Use the agent wrapper (easier)
-agent = ModalettaAgent(
-    config=config,
-    persona="I am a helpful AI assistant.",
-    human="The user is a developer."
-)
-
-response = agent.send_message("What's 25 * 47? Use run_code to calculate it.")
-for msg in response:
-    if msg.get("message_type") == "assistant_message":
-        print(msg.get("content", ""))
-
-# Streaming example
-for chunk in agent.send_message_stream("Tell me a story", stream_tokens=True):
-    if chunk.get("message_type") == "assistant_message":
-        content = chunk.get("content", "")
-        if content:
-            print(content, end="", flush=True)
-print()  # New line at end
-
-# Get agent memory
-memory = agent.get_memory()
-print(f"Memory blocks: {list(memory.keys())}")
 ```
 
-### Key API Concepts
-
-**Stateful Agents**: Letta agents maintain conversation history server-side. Always send only NEW messages, never the full history.
-
-```python
-# ✅ CORRECT - Single new message
-response = client.send_message(agent_id, "What's the weather?")
-
-# ❌ WRONG - Don't send conversation history
-response = client.send_message(agent_id, previous_messages + [new_message])
-```
-
-**Message Types**: Responses use `message_type` field to distinguish different message kinds:
-- `assistant_message`: Agent's response (has `content` field)
-- `reasoning_message`: Agent's internal reasoning (has `reasoning` field)  
-- `tool_call_message`: Agent calling a tool (has `tool_call` dict with `name` and `arguments`)
-- `tool_return_message`: Tool execution result (has `tool_return` field)
-- `usage_statistics`: Token usage information
-
-## Modal Deployment (Theoretical)
+See [modaletta/README.md](modaletta/README.md) for detailed usage instructions.
 
-**⚠️ Completely untested**
+### For the Discord Bot
 
-The codebase includes Modal deployment functions but these have not been tested:
+```bash
+cd discord
 
-```python
-import modal
-from modaletta.agent import app, create_modal_agent, send_message_modal
+# Create virtual environment (recommended)
+python -m venv .venv && source .venv/bin/activate
 
-# Theoretical usage - may not work:
-with app.run():
-    config_dict = {"letta_server_url": "http://localhost:8283"}
-    agent_id = create_modal_agent.remote(config_dict)
-    response = send_message_modal.remote(agent_id, "Hello from Modal!", config_dict)
-    print(response)
+# Install and run
+pip install -e .
+python modaletta.py
 ```
 
-## Development
+See [discord/README.md](discord/README.md) for configuration details.
 
-### Tested Commands
-```bash
-# These work:
-uv sync --extra dev             # Install with dev dependencies
-uv run pytest tests/ -v         # Run test suite (passes)
-uv run modaletta --help         # CLI help works
-```
+**Tip**: For faster installation, consider using [uv](https://docs.astral.sh/uv/) instead of pip.
 
-### Untested Commands
-```bash
-# These should work but are untested:
-ruff check .                   # Linting
-ruff format .                  # Code formatting  
-mypy .                         # Type checking
-```
+## Environment Configuration
 
-## Requirements
+Both integrations use environment variables for configuration. Create `.env` files in their respective directories:
 
-### Confirmed Working
-- Python 3.9+ (tested with 3.12)
-- Dependencies install correctly via pip/uv
+- `modaletta/.env` - For the core package
+- `discord/.env` - For the Discord bot
 
-### Required for Full Functionality (Untested)
-- Letta server running (for agent operations)
-- Modal account and authentication (for deployment)
+See the documentation in each directory for specific configuration options.

 ## Contributing
 
-This package is in early development. The most valuable contributions would be:
-1. **Testing with real Letta servers**: Verify agent operations actually work
-2. **Modal deployment testing**: Test the serverless deployment functions
-3. **Integration testing**: End-to-end workflows
-4. **Documentation improvements**: Based on actual usage experience
-
-## Architecture
-
-Modaletta provides multiple layers of abstraction:
-
-1. **ModalettaConfig**: Configuration management with environment variable support
-2. **ModalettaClient**: Low-level client wrapping the Letta Python SDK with modern API
-3. **ModalettaAgent**: High-level agent wrapper for easier usage
-4. **Modal Functions**: Serverless deployment functions for running agents on Modal
-5. **CLI**: Command-line interface for all agent operations
-
-### Why Modaletta?
-
-While you can use the Letta Python SDK directly, Modaletta provides:
-
-- **Simplified Configuration**: Environment-based config with sensible defaults
-- **Modal Integration**: Ready-to-use serverless deployment on Modal
-- **Enhanced Typing**: All responses properly typed with message_type handling
-- **CLI Tools**: Command-line interface for quick agent operations
-- **Best Practices**: Built-in patterns following Letta's latest guidelines
-
-## Known Limitations
-
-- **Modal Deployment**: Modal functions have basic testing but need real-world validation
-- **Error Handling**: Could be more comprehensive for edge cases
-- **Async Support**: Currently synchronous; async support could be added
+Contributions are welcome! Please see the individual component READMEs for specific contribution guidelines.

+# Migration Guide: Updated to Modern Letta API
+
+This document outlines the changes made to update Modaletta to use the modern Letta Python SDK.
+
+## Overview
+
+Modaletta has been updated from the old Letta API to the modern, officially supported Letta Python SDK (`letta-client`). This update ensures compatibility with the latest Letta features and follows Letta's recommended best practices.
+
+## What Changed
+
+### 1. Client API Methods
+
+**Before (Old API):**
+```python
+# Old method names
+agents = client.letta_client.list_agents()
+agent = client.letta_client.create_agent(name="test")
+client.letta_client.delete_agent(agent_id)
+response = client.letta_client.send_message(agent_id, message)
+memory = client.letta_client.get_agent_memory(agent_id)
+```
+
+**After (New API):**
+```python
+# New nested structure: client.agents.*
+agents = client.letta_client.agents.list()
+agent = client.letta_client.agents.create(name="test", memory_blocks=[...])
+client.letta_client.agents.delete(agent_id)
+response = client.letta_client.agents.messages.create(agent_id, messages=[...])
+memory = client.letta_client.agents.memory.get(agent_id)
+```
+
+### 2. Agent Creation with Memory Blocks
+
+**Before:**
+```python
+agent = client.create_agent(
+    name="my-agent",
+    persona="I am helpful",
+    human="User is a developer"
+)
+```
+
+**After:**
+```python
+agent = client.create_agent(
+    name="my-agent",
+    memory_blocks=[
+        {"label": "persona", "value": "I am helpful"},
+        {"label": "human", "value": "User is a developer"}
+    ],
+    model="openai/gpt-4.1",
+    embedding="openai/text-embedding-3-small",
+    tools=["web_search", "run_code"]
+)
+```
+
+### 3. Message Response Format
+
+**Before:**
+```python
+response = client.send_message(agent_id, "Hello")
+for msg in response:
+    text = msg.get("text", "")
+    role = msg.get("role", "")
+```
+
+**After:**
+```python
+response = client.send_message(agent_id, "Hello")
+for msg in response:
+    message_type = msg.get("message_type", "")
+    if message_type == "assistant_message":
+        content = msg.get("content", "")
+    elif message_type == "tool_call_message":
+        tool_call = msg.get("tool_call", {})
+    elif message_type == "tool_return_message":
+        tool_return = msg.get("tool_return", "")
+```
+
+### 4. Configuration Updates
+
+**New Default Models:**
+- `llm_model`: `openai/gpt-4.1` (was `gpt-4`)
+- `embedding_model`: `openai/text-embedding-3-small` (new field)
+- `tools`: Comma-separated list via `MODALETTA_TOOLS` env var (new field)
+
+### 5. Streaming Support
+
+**New Feature:**
+```python
+# Stream responses
+for chunk in client.send_message_stream(agent_id, "Tell me a story", stream_tokens=True):
+    if chunk.get("message_type") == "assistant_message":
+        print(chunk.get("content", ""), end="", flush=True)
+```
+
+## Updated Files
+
+### Core Files
+- **`src/modaletta/client.py`**: Updated all API calls to use modern nested structure
+- **`src/modaletta/config.py`**: Added embedding model and tools configuration
+- **`src/modaletta/agent.py`**: Added streaming support and better initialization
+- **`src/modaletta/cli.py`**: Updated to handle new message types with `--stream` flag

+
+### Examples
+- **`examples/basic_agent.py`**: Updated to use new API patterns
+- **`examples/modal_deployment.py`**: Updated message handling
+
+### Documentation
+- **`README.md`**: Comprehensive update with modern examples
+- **`MIGRATION_GUIDE.md`**: This file
+
+## Key Differences from Raw Letta SDK
+
+While Modaletta now uses the modern Letta SDK, it provides additional benefits:
+
+1. **Simplified Configuration**: Environment-based config with sensible defaults
+2. **Convenience Methods**: Higher-level abstractions for common operations
+3. **Modal Integration**: Ready-to-use serverless deployment functions
+4. **CLI Tools**: Command-line interface for quick operations
+5. **Type Hints**: Full type hints for better IDE support
+
+## Environment Variables
+
+New/updated environment variables:
+
+```bash
+# Updated defaults
+MODALETTA_LLM_MODEL=openai/gpt-4.1  # was gpt-4
+MODALETTA_EMBEDDING_MODEL=openai/text-embedding-3-small  # new
+
+# New: Tools configuration
+MODALETTA_TOOLS=web_search,run_code  # comma-separated list
+```
+
+## Breaking Changes
+
+1. **Response Format**: All message responses now use `message_type` instead of `role`/`text`
+2. **Model Names**: Must include provider prefix (e.g., `openai/gpt-4.1` not just `gpt-4`)
+3. **Agent Creation**: Memory blocks are now explicitly structured
+4. **Memory Methods**: Changed from `get_agent_memory` to nested `agents.memory.get`
+
+## Testing
+
+All tests pass with the new API:
+```bash
+$ python -m pytest tests/ -v
+============================= test session starts ==============================
+tests/test_client.py::test_client_initialization PASSED
+tests/test_client.py::test_letta_client_property PASSED

+======================== 10 passed in 0.86s ========================
+```
+
+## Migration Checklist
+
+If you have existing code using Modaletta, follow these steps:
+
+- [ ] Update environment variables with new defaults
+- [ ] Update any custom agent creation code to use `memory_blocks`
+- [ ] Update message response parsing to use `message_type` instead of `role`
+- [ ] Add provider prefixes to model names (e.g., `openai/`)
+- [ ] Test with a Letta server (self-hosted or Letta Cloud)
+- [ ] Consider using new streaming features

+# Modaletta
+
+**✨ Updated for Modern Letta API**: This package now uses the latest Letta Python SDK with proper agent creation, memory blocks, and message handling.
+
+A Python package that integrates [Letta](https://docs.letta.com) (AI agent framework) with [Modal](https://modal.com/docs) (serverless platform) for scalable stateful AI agent deployment.
+
+## Current Status
+
+### ✅ What's New (v0.1.0)
+- **Modern Letta API**: Updated to use latest Letta Python SDK
+  - Uses `client.agents.create()` with `memory_blocks` parameter
+  - Proper message handling with `message_type` field
+  - Support for streaming responses
+  - Built-in tools support (`web_search`, `run_code`)
+- **Improved Configuration**: 
+  - Modern model defaults (`openai/gpt-4.1`, `openai/text-embedding-3-small`)
+  - Tool configuration support
+  - Embedding model configuration
+- **Enhanced CLI**: 
+  - Streaming support with `--stream` flag
+  - Better message type handling and display
+- **Updated Tests**: All tests pass with proper mocking of new API structure
+
+### 🧪 Ready to Test
+The codebase provides:
+- **Letta Integration**: Complete wrapper around modern letta-client API
+- **Modal Deployment**: Serverless functions for agent execution on Modal
+- **Agent Management**: High-level abstractions for stateful agent operations
+- **CLI Commands**: Full command-line interface with streaming support
+
+### 📋 Prerequisites for Testing
+- **Letta Server**: Self-hosted or Letta Cloud account with API key
+- **OpenAI API Key**: For using default models (or configure other models)
+- **Modal Account**: Only needed for serverless deployment features
+
+## Installation
+
+**From Source (Recommended for now)**:
+
+```bash
+git clone https://github.com/jakemannix/modaletta.git
+cd modaletta/modaletta
+```
+
+**Create a virtual environment** (recommended):
+
+```bash
+# Standard approach
+python -m venv .venv
+source .venv/bin/activate  # On Windows: .venv\Scripts\activate
+
+# Or use uv (modern, faster alternative - install from https://docs.astral.sh/uv/)
+uv venv
+source .venv/bin/activate  # On Windows: .venv\Scripts\activate
+```
+
+**Install the package**:
+
+```bash
+# Standard pip
+pip install -e .
+
+# Or with uv (much faster)
+uv pip install -e .
+```
+
+## Quick Start
+
+1. **Set up environment variables**:
+
+Create a `.env` file in your project root:
+
+```bash
+# For Letta Cloud (easiest)
+LETTA_SERVER_URL=https://api.letta.com
+LETTA_API_KEY=your_letta_api_key_here  # Get from https://app.letta.com/api-keys
+
+# For self-hosted Letta
+# LETTA_SERVER_URL=http://localhost:8283
+```
+
+2. **Verify basic functionality**:
+
+```bash
+modaletta --help
+modaletta config-info
+```
+
+3. **Create and use an agent**:
+
+```bash
+# Create an agent with custom persona
+modaletta create-agent \
+  --name "my-assistant" \
+  --persona "I am a helpful AI assistant specializing in Python development." \
+  --human "The user is a Python developer."
+
+# List all agents
+modaletta list-agents
+
+# Send a message (use the agent ID from list-agents)
+modaletta send-message <agent-id> "Hello! Can you help me debug some Python code?"
+
+# Send with streaming (see response as it's generated)
+modaletta send-message --stream <agent-id> "Tell me a story about AI."
+
+# View agent memory
+modaletta get-memory <agent-id>
+```
+
+## Configuration
+
+Modaletta uses environment variables for configuration:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `LETTA_SERVER_URL` | Letta server URL (use `https://api.letta.com` for Letta Cloud) | `http://localhost:8283` |
+| `LETTA_API_KEY` | Letta API key (required for Letta Cloud) | None |
+| `MODAL_TOKEN_ID` | Modal token ID | None |
+| `MODAL_TOKEN_SECRET` | Modal token secret | None |
+| `MODALETTA_AGENT_NAME` | Default agent name | `modaletta-agent` |
+| `MODALETTA_MEMORY_CAPACITY` | Agent memory capacity | `2000` |
+| `MODALETTA_LLM_MODEL` | LLM model to use (with provider prefix) | `openai/gpt-4.1` |
+| `MODALETTA_EMBEDDING_MODEL` | Embedding model to use | `openai/text-embedding-3-small` |
+| `MODALETTA_TEMPERATURE` | LLM temperature | `0.7` |
+| `MODALETTA_TOOLS` | Comma-separated list of tools | `` (empty) |
+
+### Example `.env` file
+
+```bash
+# For Letta Cloud
+LETTA_SERVER_URL=https://api.letta.com
+LETTA_API_KEY=your_letta_api_key_here
+
+# For self-hosted Letta
+# LETTA_SERVER_URL=http://localhost:8283
+# LETTA_API_KEY=  # Optional for self-hosted
+
+# Model configuration
+MODALETTA_LLM_MODEL=openai/gpt-4.1
+MODALETTA_EMBEDDING_MODEL=openai/text-embedding-3-small
+MODALETTA_TOOLS=web_search,run_code
+
+# Optional Modal configuration (only needed for serverless deployment)
+# MODAL_TOKEN_ID=your_modal_token_id
+# MODAL_TOKEN_SECRET=your_modal_token_secret
+
+# Optional: E2B API key for run_code tool (get free key at https://e2b.dev)
+# E2B_API_KEY=your_e2b_api_key
+```
+
+**Note**: The `run_code` tool requires an E2B API key for self-hosted servers. It works automatically on Letta Cloud. Get a free key at [e2b.dev](https://e2b.dev).
+
+## Python API
+
+### Quick Start
+
+```python
+from modaletta import ModalettaAgent, ModalettaClient, ModalettaConfig
+
+# Configure (loads from environment variables)
+config = ModalettaConfig.from_env()
+config.tools = ["web_search", "run_code"]  # Add built-in tools
+
+# Option 1: Use the client directly
+client = ModalettaClient(config)
+agent_id = client.create_agent(
+    name="my-assistant",
+    persona="I am a helpful AI assistant that specializes in coding and research.",
+    human="The user is a Python developer working on AI projects."
+)
+
+# Send a message (note: Letta agents are STATEFUL, only send new messages)
+response = client.send_message(agent_id, "Hello! Can you help me with Python?")
+
+# Process response with proper message_type handling
+for msg in response:
+    message_type = msg.get("message_type", "")
+    if message_type == "assistant_message":
+        print(f"Assistant: {msg.get('content', '')}")
+    elif message_type == "tool_call_message":
+        tool_call = msg.get("tool_call", {})
+        print(f"[Calling tool: {tool_call.get('name', '')}]")
+    elif message_type == "tool_return_message":
+        print(f"[Tool result: {msg.get('tool_return', '')}]")
+
+# Option 2: Use the agent wrapper (easier)
+agent = ModalettaAgent(
+    config=config,
+    persona="I am a helpful AI assistant.",
+    human="The user is a developer."
+)
+
+response = agent.send_message("What's 25 * 47? Use run_code to calculate it.")
+for msg in response:
+    if msg.get("message_type") == "assistant_message":
+        print(msg.get("content", ""))
+
+# Streaming example
+for chunk in agent.send_message_stream("Tell me a story", stream_tokens=True):
+    if chunk.get("message_type") == "assistant_message":
+        content = chunk.get("content", "")
+        if content:
+            print(content, end="", flush=True)
+print()  # New line at end
+
+# Get agent memory
+memory = agent.get_memory()
+print(f"Memory blocks: {list(memory.keys())}")
+```
+
+### Key API Concepts
+
+**Stateful Agents**: Letta agents maintain conversation history server-side. Always send only NEW messages, never the full history.
+
+```python
+# ✅ CORRECT - Single new message
+response = client.send_message(agent_id, "What's the weather?")
+
+# ❌ WRONG - Don't send conversation history
+response = client.send_message(agent_id, previous_messages + [new_message])
+```
+
+**Message Types**: Responses use `message_type` field to distinguish different message kinds:
+- `assistant_message`: Agent's response (has `content` field)
+- `reasoning_message`: Agent's internal reasoning (has `reasoning` field)  
+- `tool_call_message`: Agent calling a tool (has `tool_call` dict with `name` and `arguments`)
+- `tool_return_message`: Tool execution result (has `tool_return` field)
+- `usage_statistics`: Token usage information
+
+## Modal Deployment (Theoretical)
+
+**⚠️ Completely untested**
+
+The codebase includes Modal deployment functions but these have not been tested:
+
+```python
+import modal
+from modaletta.agent import app, create_modal_agent, send_message_modal
+
+# Theoretical usage - may not work:
+with app.run():
+    config_dict = {"letta_server_url": "http://localhost:8283"}
+    agent_id = create_modal_agent.remote(config_dict)
+    response = send_message_modal.remote(agent_id, "Hello from Modal!", config_dict)
+    print(response)
+```
+
+## Development
+
+### Tested Commands
+```bash
+# These work:
+pip install -e .[dev]           # Install with dev dependencies
+python -m pytest tests/ -v     # Run test suite (passes)
+modaletta --help               # CLI help works
+```
+
+### Untested Commands
+```bash
+# These should work but are untested:
+ruff check .                   # Linting
+ruff format .                  # Code formatting  
+mypy .                         # Type checking
+```
+
+## Requirements
+
+### Confirmed Working
+- Python 3.9+ (tested with 3.12)
+- Dependencies install correctly via pip/uv
+
+### Required for Full Functionality (Untested)
+- Letta server running (for agent operations)
+- Modal account and authentication (for deployment)
+
+## License
+
+MIT License - see [LICENSE](LICENSE) for details.
+
+## Contributing
+
+This package is in early development. The most valuable contributions would be:
+1. **Testing with real Letta servers**: Verify agent operations actually work
+2. **Modal deployment testing**: Test the serverless deployment functions
+3. **Integration testing**: End-to-end workflows
+4. **Documentation improvements**: Based on actual usage experience
+
+## Architecture
+
+Modaletta provides multiple layers of abstraction:
+
+1. **ModalettaConfig**: Configuration management with environment variable support
+2. **ModalettaClient**: Low-level client wrapping the Letta Python SDK with modern API
+3. **ModalettaAgent**: High-level agent wrapper for easier usage
+4. **Modal Functions**: Serverless deployment functions for running agents on Modal
+5. **CLI**: Command-line interface for all agent operations
+
+### Why Modaletta?
+
+While you can use the Letta Python SDK directly, Modaletta provides:
+
+- **Simplified Configuration**: Environment-based config with sensible defaults
+- **Modal Integration**: Ready-to-use serverless deployment on Modal
+- **Enhanced Typing**: All responses properly typed with message_type handling
+- **CLI Tools**: Command-line interface for quick agent operations
+- **Best Practices**: Built-in patterns following Letta's latest guidelines
+
+## Migration from Old Letta API
+
+If you have existing code using the old Letta API, here are the key changes:
+
+```python
+# OLD API (deprecated)
+from letta import create_client
+client = create_client()
+agent = client.create_agent(name="test")
+response = client.user_message(agent_id, "Hello")
+
+# NEW API (Modaletta with modern Letta)
+from modaletta import ModalettaClient
+client = ModalettaClient()
+agent_id = client.create_agent(
+    name="test",
+    persona="I am a helpful assistant",
+    human="The user is a developer"
+)
+response = client.send_message(agent_id, "Hello")
+
+# Response format changed:
+# OLD: response["messages"][0]["text"]
+# NEW: response[0]["content"] (if message_type == "assistant_message")
+```
+
+## Known Limitations
+
+- **Modal Deployment**: Modal functions have basic testing but need real-world validation
+- **Error Handling**: Could be more comprehensive for edge cases
+- **Async Support**: Currently synchronous; async support could be added
+
+## Support
