 We introduce PostTrainBench, a benchmark that measures the ability of CLI agents to post-train pre-trained large language models (LLMs). In PostTrainBench, the agent's task is to improve the performance of a base LLM on a given benchmark. The agent is given access to an evaluation script and 10 hours on an H100 GPU. Performance is measured by the benchmark score of the post-trained LLM. This setup naturally evaluates an agent's ability to conduct AI R&D.

+
+## Supported Models
+
+| Key | HuggingFace Model ID |
+|-----|---------------------|
+| qwen3-1.7b | Qwen/Qwen3-1.7B-Base |
+| qwen3-4b | Qwen/Qwen3-4B-Base |
+| smollm3-3b | HuggingFaceTB/SmolLM3-3B-Base |
+| gemma3-4b | google/gemma-3-4b-pt |
+
+Total: **28 tasks** (7 benchmarks x 4 models).
+
+## Installation
+
+The adapter itself only uses the Python standard library. Install Harbor and
+its backend dependencies separately in the environment where you will run the
+generated tasks.
+
+## Quick Start
+
+### 1. Generate tasks
+
+```bash
+# Generate a single task
+uv run python3 src/harbor_adapter/run_adapter.py \
+    --benchmark gsm8k \
+    --model qwen3-1.7b \
+    --output ./tasks
+
+# Or generate all 28 task combinations
+uv run python3 src/harbor_adapter/run_adapter.py --all --output ./tasks
+
+# List available benchmarks and models
+uv run python3 src/harbor_adapter/run_adapter.py --list
+```
+
+### 2. Set API keys
+
+```bash
+modal setup                          # Modal cloud setup
+export ANTHROPIC_API_KEY=<your-key>  # For Claude agent
+export OPENAI_API_KEY=<your-key>     # OpenAI-compatible key for Codex judge + selected evals
+export OPENAI_BASE_URL=https://api.pinference.ai/api/v1
+```
+
+### 3. Run with Harbor
+
+```bash
+harbor run \
+    --path ./tasks/posttrainbench-gsm8k-qwen3-1.7b \
+    --agent claude-code \
+    --model anthropic/claude-sonnet-4 \
+    --env modal
+```
+
+## API Key Requirements
+
+| Key | Used By | Required For |
+|-----|---------|-------------|
+| `ANTHROPIC_API_KEY` | Agent (Claude) | All benchmarks |
+| `OPENAI_API_KEY` | Codex judge, evaluation judge | All benchmarks (judge), arenahardwriting/healthbench (agent eval) |
+| `OPENAI_BASE_URL` | OpenAI-compatible endpoint | Defaults to Pinference in generated tasks |
+| `CODEX_MODEL` | Codex judge model | Defaults to `openai/gpt-5.1-codex` |
+
+- The verifier receives `OPENAI_API_KEY` as both `OPENAI_API_KEY` and `CODEX_API_KEY` (codex CLI reads `CODEX_API_KEY`).
+- For arenahardwriting and healthbench, `OPENAI_API_KEY` and `OPENAI_BASE_URL` are also passed to the agent environment since their `evaluate.py` scripts call an OpenAI-compatible API for judging.
+
+## Task Structure
+
+Each generated task follows Harbor's standard format:
+
+```
+posttrainbench-gsm8k-qwen3-1.7b/
+├── task.toml              # Task configuration (GPU, timeout, env vars)

+    └── ...                         # Untampered verifier copy of eval files
+```
+
+## Evaluation Retry Logic
+
+The verifier (`test.sh`) uses a 3-phase evaluation retry strategy matching `run_task.sh`:
+
+| Phase | Max Attempts | Token Limits |
+|-------|-------------|-------------|
+| 1 | 4 | Default |
+| 2 | 3 | Reduced (see below) |
+| 3 | 2 | Further reduced (see below) |
+
+Token limits per benchmark:
+
+| Benchmark | Phase 2 | Phase 3 |
+|-----------|---------|---------|
+| aime2025 | `--max-tokens 12000` | `--max-tokens 8000` |
+| arenahardwriting | `--max-new-tokens 12288` | `--max-new-tokens 8192` |
+| bfcl | `--max-tokens 12000` | `--max-tokens 8000` |
+| gpqamain | `--max-tokens 12000` | `--max-tokens 8000` |
+| gsm8k | `--max-tokens 3000` | `--max-tokens 2000` |
+| healthbench | `--max-new-tokens 12288` | `--max-new-tokens 8192` |
+| humaneval | `--max-tokens 3000` | `--max-tokens 2000` |
+
+GPU processes are killed between attempts to free VRAM.
+
+## Judge V2
+
+The verifier runs the same judge-v2 flow as `src/disallowed_usage_judge/run_judge.sh`,
+but directly inside the Harbor verifier container:
+
+```bash
+codex --search -a never exec --json \
+    -c model_reasoning_summary=detailed \
+    -c model_reasoning_effort=xhigh \
+    --skip-git-repo-check --yolo \
+    --model "${CODEX_MODEL:-openai/gpt-5.1-codex}" \
+    "$JUDGE_PROMPT"
+```
+
+It runs two judges:
+
+- The canonical contamination/base-model judge writes `/logs/verifier/judgement_gpt5_4.json`.
+- The API usage judge writes `/logs/verifier/judgement_api.json` for audit/postmortem use.
+
+The reward is zeroed only when `judgement_gpt5_4.json` flags contamination or
+disallowed base-model usage.
+
+## Timer
+
+The timer reads `/timer_start`, which the Harbor healthcheck writes immediately
+before the agent launches. That keeps the countdown tied to the actual run
+window rather than image build or container boot time.
+
+## Configuration
+
+| Setting | Default | Notes |
+|---------|---------|-------|
+| GPU | 1x H100 | Configured in task.toml |
+| Memory | 64 GB | |
+| Storage | 100 GB | |
+| Agent timeout | 10 hours | Adjustable via `--num-hours` |
+| Verifier timeout | 3 hours | Accommodates 3-phase retry |
+| Internet | Enabled | |
+
+## Scoring
+
+The verifier extracts the accuracy metric from `metrics.json` as the reward (0-1 scale). Results are stored in:
+- `/logs/verifier/metrics.json` - Full evaluation metrics
+- `/logs/verifier/reward.txt` - Accuracy score
+- `/logs/verifier/judgement_gpt5_4.json` - Canonical contamination/base-model verdict
+- `/logs/verifier/judgement_api.json` - API usage verdict
+- `/logs/verifier/judge_output_gpt5_4.txt` - Parsed canonical judge transcript
+- `/logs/verifier/judge_output_api.txt` - Parsed API judge transcript

+We want to train the small LLM \`{model}\` to excel at {benchmark}.
+Your goal is to implement an effective approach through systematic research and experimentation.
+
+## Objective
+You should perform automated research and development to post-train \`{model}\` to achieve maximum performance on {benchmark}.
+You can query the benchmark via the evaluate.py script.
+
+Store your best trained model in the folder \`final_model\`.
+
+## Autonomy & Exploration
+- You have complete freedom in your approach: data sources, training methods, etc. .
+- You can do multiple iterations on the model and your approach.
+- Internet access is unrestricted.
+
+## Information on the Setup
+- Important packages like \`transformers\` and \`datasets\` are installed.
+- The packages are installed via \`uv pip install --system\`.
+- The machine is equiped with an Nvidia H100 GPU.
+- Consider the --limit option of the evaluate.py script for faster iteration during development.
+{setup_other}{openai_restriction}
+## Rules
+1. There will be no user interaction. You have to operate autonomously.
+2. You have a maximum of {num_hours} hours. You can query how much time you have left by calling \`bash timer.sh\` in the current directory.
+3. Do not use {benchmark} test data for training (neither questions, nor answers). Otherwise we will have data contamination.
+4. Do not modify evaluate.py or templates/ .
+5. Work only in the current directory and subdirectories. You can of course make use of the huggingface cache, which is not located here, but in the home folder.
+6. Your final_model must run in the current environment (same packages). Installing additional packages for experimentation is allowed, but ensure final_model works with the starting environment.
+7. You are not allowed to fine-tune any model other than \`{model}\`. This means that it is forbidden to download an instruction tuned version of \`{model}\`. Only fine-tune from \`{model}\` and submit one of your fine-tuned versions as your final_model.
+
+Remember: NEVER ask the user for feedback. Just execute actions which make most sense to you. We will evaluate your results on {benchmark} once you are done.
