scripts/run_post_train_eval.sh

#!/usr/bin/env bash
# Run all evals after the production training jobs finish.
#
# This script orchestrates the post-training eval sweep:
#   1. Policy baseline (deterministic, no LLM)
#   2. Base model eval per size (Qwen3-0.6B / 1.7B / 4B, untrained)
#   3. Trained model eval per size (3 trained checkpoints)
#
# Outputs go to outputs/eval_<model>_<base|trained>.json — exactly the
# layout consumed by scripts/make_plots.py.
#
# Required env (one HF write-token with read access to the trained model repos):
#   HF_TOKEN          token for downloading the trained models from HF Hub
#
# Optional env:
#   ENV_BASE_URL      default https://agarwalanu3103-clarify-rl.hf.space
#   API_BASE_URL      default https://router.huggingface.co/v1 (HF Inference Router)
#   LIMIT             max scenarios to evaluate (default 100, set to 300 for full)
#   TIMEOUT_S         per-scenario timeout (default 60)
#   SKIP_POLICY       "1" to skip the policy baseline (already have it)
#   SKIP_BASE         "1" to skip base-model evals
#   SKIP_TRAINED      "1" to skip trained-model evals
#
# Usage:
#   HF_TOKEN=hf_xxx ./scripts/run_post_train_eval.sh
#
# Trained model repo names (these are the OUTPUT_DIRs from launch_all.sh):
#   <username>/clarify-rl-grpo-qwen3-0-6b
#   <username>/clarify-rl-grpo-qwen3-1-7b
#   <username>/clarify-rl-grpo-qwen3-4b
#
# Set MODEL_0_6B / MODEL_1_7B / MODEL_4B env vars if your usernames differ.
