# SLM-Lab Benchmarks

Reproducible deep RL algorithm validation across Gymnasium environments (Classic Control, Box2D, MuJoCo, Atari).

---

## Usage

After [installation](../README.md#quick-start), copy `SPEC_FILE` and `SPEC_NAME` from result tables below (Atari uses one shared spec file - see [Phase 4](#phase-4-atari)).

### Running Benchmarks

**Local** - runs on your machine (Classic Control: minutes):
```bash
slm-lab run SPEC_FILE SPEC_NAME train
```

**Remote** - cloud GPU via [dstack](https://dstack.ai), auto-syncs to HuggingFace:
```bash
source .env && slm-lab run-remote --gpu SPEC_FILE SPEC_NAME train -n NAME
```

Remote setup: `cp .env.example .env` then set `HF_TOKEN`. See [README](../README.md#cloud-training-dstack) for dstack config.

### Atari

All games share one spec file (54 tested, 5 hard exploration skipped). Use `-s env=ENV` to substitute. Runs take ~2-3 hours on GPU.

```bash
source .env && slm-lab run-remote --gpu -s env=ALE/Pong-v5 slm_lab/spec/benchmark/ppo/ppo_atari.json ppo_atari train -n pong
```

### Download Results

Trained models and metrics sync to [HuggingFace](https://huggingface.co/datasets/SLM-Lab/benchmark). Pull locally:
```bash
source .env && slm-lab pull SPEC_NAME
slm-lab list  # see available experiments
```

### Benchmark Contribution
To ensure benchmark integrity, follow these steps when adding or updating results:

#### 1. Audit Spec Settings
*   **Before Running**: Ensure `spec.json` matches the **Settings** line defined in each benchmark table.
*   **Example**: `max_frame 3e5 | num_envs 4 | max_session 4 | log_frequency 500`
*   **After Pulling**: Verify the downloaded `spec.json` matches these rules before using the data.

#### 2. Run Benchmark & Commit Specs
*   **Run**: Execute the benchmark locally or remotely using the commands in [Usage](#usage).
*   **Commit Specs**: Always commit the `spec.json` file used for the run to the repo.
*   **Table Entry**: Ensure `BENCHMARKS.md` has an entry with the correct `SPEC_FILE` and `SPEC_NAME`.

#### 3. Record Scores & Plots
*   **Score**: At run completion, extract `total_reward_ma` from logs (`trial_metrics`).
*   **Link**: Add HuggingFace folder link: `[FOLDER](https://huggingface.co/datasets/SLM-Lab/benchmark/tree/main/data/FOLDER)`
*   **Pull data**: `source .env && uv run hf download SLM-Lab/benchmark --include "data/FOLDER/*" --local-dir hf_data --repo-type dataset`
*   **Plot**: Generate with folders from table:
    ```bash
    slm-lab plot -t "CartPole-v1" -f ppo_cartpole_2026...,dqn_cartpole_2026...
    ```

### Environment Settings

Standardized settings for fair comparison. The **Settings** line in each result table shows these values.

| Env Category | num_envs | max_frame | log_frequency | grace_period |
|--------------|----------|-----------|---------------|--------------|
| Classic Control | 4 | 2e5-3e5 | 500 | 1e4 |
| Box2D | 8 | 3e5 | 1000 | 5e4 |
| MuJoCo | 16 | 1e6-10e6 | 1e4 | 1e5-1e6 |
| Atari | 16 | 10e6 | 10000 | 5e5 |

### Hyperparameter Search

When algorithm fails to reach target, run search instead of train:

```bash
slm-lab run SPEC_FILE SPEC_NAME search                                        # local
source .env && slm-lab run-remote --gpu SPEC_FILE SPEC_NAME search -n NAME    # remote
```

| Stage | Mode | Config | Purpose |
|-------|------|--------|---------|
| ASHA | `search` | `max_session=1`, `search_scheduler` enabled | Wide exploration with early stopping |
| Multi | `search` | `max_session=4`, NO `search_scheduler` | Robust validation with averaging |
| Validate | `train` | Final spec | Confirmation run |

> Do not use search result in benchmark results - use final validation run with committed spec.

Search budget: ~3-4 trials per dimension (8 trials = 2-3 dims, 16 = 3-4 dims, 20+ = 5+ dims).

```json
{
  "meta": {
    "max_session": 1, "max_trial": 16,
    "search_resources": {"cpu": 1, "gpu": 0.125},
    "search_scheduler": {"grace_period": 1e5, "reduction_factor": 3}
  },

  }
}
```

### Phase 3: MuJoCo

**Docs**: [MuJoCo environments](https://gymnasium.farama.org/environments/mujoco/) | State/Action: Continuous | Target: Practical baselines (no official "solved" threshold)

**Settings**: max_frame 4e6-10e6 | num_envs 16 | max_session 4 | log_frequency 1e4

**Algorithm: PPO only** - SAC omitted (off-policy = heavy compute for systematic benchmarking). Network: MLP [256,256] tanh, orthogonal init.

**Spec Variants**: Two unified specs in [ppo_mujoco.json](../slm_lab/spec/benchmark/ppo/ppo_mujoco.json), plus individual specs for edge cases.

| SPEC_NAME | Envs | Key Config |
|-----------|------|------------|
| ppo_mujoco | HalfCheetah, Walker, Humanoid, HumanoidStandup | gamma=0.99, lam=0.95 |
| ppo_mujoco_longhorizon | Reacher, Pusher | gamma=0.997, lam=0.97 |
| Individual specs | Hopper, Swimmer, Ant, IP, IDP | See spec files for tuned hyperparams |

**Reproduce**: Copy `ENV`, `SPEC_FILE`, `SPEC_NAME` from table. Use `-s max_frame=` for all specs, add `-s env=` for unified specs:
```bash
# Unified specs (ppo_mujoco.json)
source .env && slm-lab run-remote --gpu -s env=ENV -s max_frame=MAX_FRAME \
  slm_lab/spec/benchmark/ppo/ppo_mujoco.json SPEC_NAME train -n NAME

# Individual specs (env hardcoded)
source .env && slm-lab run-remote --gpu -s max_frame=MAX_FRAME \

### Phase 4: Atari

**Docs**: [Atari environments](https://ale.farama.org/environments/) | State: Box(84,84,4 after preprocessing) | Action: Discrete(4-18, game-dependent)

**Settings**: max_frame 10e6 | num_envs 16 | max_session 4 | log_frequency 10000

**Environment**:
- Gymnasium ALE v5 with `life_loss_info=true`
- v5 uses sticky actions (`repeat_action_probability=0.25`) per [Machado et al. (2018)](https://arxiv.org/abs/1709.06009) best practices

**Algorithm Specs** (all use Nature CNN [32,64,64] + 512fc):
- **DDQN+PER**: Skipped - off-policy variants ~6x slower (~230 fps vs ~1500 fps), not cost effective at 10M frames
- **A2C**: [a2c_gae_atari.json](../slm_lab/spec/benchmark/a2c/a2c_gae_atari.json) - RMSprop (lr=7e-4), training_frequency=32
- **PPO**: [ppo_atari.json](../slm_lab/spec/benchmark/ppo/ppo_atari.json) - AdamW (lr=2.5e-4), minibatch=256, horizon=128, epochs=4

**PPO Lambda Variants** (table shows best result per game):

| SPEC_NAME | Lambda | Best for |
|-----------|--------|----------|
| ppo_atari | 0.95 | Strategic games (default) |
| ppo_atari_lam85 | 0.85 | Mixed games |
| ppo_atari_lam70 | 0.70 | Action games |

**Reproduce**:
