# OpenPoker

[![PyPI version](https://badge.fury.io/py/openpoker.svg)](https://badge.fury.io/py/openpoker)

A Python poker engine (with a terminal UI) for building LLM poker apps, servers, and custom interfaces. Play against LLMs from OpenAI, Anthropic, and Openrouter.

## Terminal UI

Play Texas Hold'em No-Limit against agents directly in your terminal:

- **Agent memory** allows agents to store insights and observations at the end of each hand, learning opponent playing styles and carrying knowledge from one hand to another within a game session
- **Player personalities** can be configured to create distinct playing styles and behaviors for each agent
- **Model selection** supports OpenAI, Anthropic, and OpenRouter models, letting you mix different LLM providers at the same table
- **Agent rationales** are produced for every decision and can be viewed in debug mode, showing the reasoning behind each action
- **Tool-based decisions** use function calling to structure agent actions, with game state presented through context assembly that includes hand strength, pot odds, opponent behaviors, and historical insights
- **Monte Carlo simulation** using Treys provides agents with win probability statistics to inform their decision-making and increase gameplay difficulty
- **Pot odds and EV calculations** are automatically computed and available to agents for more strategic play
- **Type-safe** implementation with full type hints and Pydantic models throughout

## Quick Install

```bash
pip install openpoker
```

## Run the Terminal UI

```bash
openpoker
```

Or with debug mode:

```bash
openpoker --debug
```

The terminal will prompt for API keys if needed, or you can create a `.env` file:

```bash
OPENAI_API_KEY=your_openai_key
ANTHROPIC_API_KEY=your_anthropic_key
OPENROUTER_API_KEY=your_openrouter_key
```

## Development Install

```bash
git clone https://github.com/philippe-page/openpoker.git
cd openpoker
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -e ".[dev]"
```

## OpenPoker Engine

OpenPoker's terminal UI runs on a standalone engine designed as a library for building LLM-powered poker applications. The engine is built on PokerKit for game state and rule enforcement, and uses Treys for fast Monte Carlo simulations. The event-driven architecture makes it suitable for building servers, web applications with SSE or WebSocket transports, custom clients, or integrating poker gameplay into larger systems.

The engine handles game state, rule enforcement, agent decision orchestration, and emits granular events for every game action. Build React frontends, multiplayer servers, training environments, or any poker application on top of the same engine that powers the terminal UI.

### Engine quickstart

```python
from openpoker import (
    AIProvider, ActionType, EngineOptions, GameConfig,
    PlayerConfig, PlayerType, PokerAction, PokerEngine,
)

engine = PokerEngine(
    options=EngineOptions(enable_memory=True, enable_monte_carlo=True)
)

game_id = engine.create_game(
    game_name=table_name,
    config=GameConfig(small_blind=small_blind, big_blind=big_blind, starting_stack=buy_in),
    players=[
        PlayerConfig(id=user_id, name=display_name, player_type=PlayerType.HUMAN),
        PlayerConfig(id=agent_id, name=agent_name, player_type=PlayerType.AI, provider=provider, model=model),
    ],
)

snapshot = engine.start_hand(game_id)

while snapshot.hand_active:
    if snapshot.current_actor_id == user_id:
        available = engine.get_available_actions(game_id, user_id)
        action = get_action_from_client(available)
        snapshot = await engine.submit_action(game_id, user_id, action)
    else:
        snapshot = await engine.step(game_id)
```

### Events and app integration

Subscribe once, then push events to whatever transport your app uses (SSE, websocket, queue, logs).

```python
def on_event(event):
    data = event.model_dump(mode="json")
    print(event.event_type.value, data["sequence"])

unsubscribe = engine.subscribe(on_event)
```

Event types:
- `game_created` - New game initialized with players
- `hand_started` - New hand dealt, blinds posted
- `action_required` - Player needs to act, includes available actions
- `action_applied` - Player action processed (fold, check, call, bet, raise)
- `street_changed` - Flop, turn, or river dealt
- `showdown` - Hand complete, winners determined
- `player_eliminated` - Player out of chips
- `game_over` - Single player remains
- `ai_decision` - AI agent decision with rationale and metadata
- `engine_error` - Error occurred during game processing

### Snapshots

Use snapshots as read-model state for clients:

```python
snapshot = engine.get_snapshot(game_id, viewer_id=user_id)
```

Tutor/admin view can reveal all hole cards:

```python
snapshot = engine.get_snapshot(game_id, reveal_all_hole_cards=True)
```

### Agent payloads

Agent decisions return normalized metadata including:
- `provider` and `model`
- `rationale`
- tool call name and arguments
- token usage details (input/output/total, provider-specific fields when available)

### Examples

See `examples/`:
- `examples/server_like_loop.py`
- `examples/api_style_session.py`
- `examples/sse_event_stream.py`
