+# Causal GPT-RL
+
+GPT-style transformers (GPT-2, Llama) running as RL policies in continuous-control environments.
+
+```text
+action → next state → next action      (RL rollouts)
+token  → next token  → next token      (LLM generation)
+```
+
+Stable under self-generated rollouts — long-horizon control without the drift that has historically kept transformers from being usable as RL agents.
+
+## Get started
+
+```bash
+pip install "causal-gpt-rl[hub,mujoco]"
+```
+
+```python
+import gymnasium as gym
+from causal_gpt_rl.inference import load_runner_from_hub, run_episodes
+
+env = gym.make("Ant-v5")
+runner = load_runner_from_hub(
+    repo_id="ccnets/causal-gpt-rl",
+    subfolder="ant-v5",
+    device="cpu",
+)
+stats = run_episodes(env, runner, num_episodes=5, seed=0)
+```
