Benchmarking AI Agents with OpenClaw Framework
The OpenClaw Agent Evaluation Framework, built into UBOS’s Full‑Stack Template, lets you benchmark GPT‑4, Claude, and Gemini in minutes with just a few lines of code.
1. Introduction
AI agents are becoming the backbone of modern applications—from chat assistants to autonomous decision‑makers. Yet, developers often struggle to answer a simple question: Which model delivers the best performance for my workload? UBOS solves this dilemma by embedding the OpenClaw hosting page into a ready‑to‑run Full‑Stack Template. In this guide you’ll see how to spin up a benchmark environment, compare GPT‑4, Claude, and Gemini, and interpret the results—all within the UBOS platform overview.
2. Why Benchmark AI Agents?
Benchmarking is not a luxury; it’s a necessity for three core reasons:
- Cost control: Large‑scale models charge per token. Knowing which model gives you the best ROI prevents budget overruns.
- Latency requirements: Real‑time applications (e.g., voice assistants) need sub‑second responses. Benchmarks reveal which model meets your SLA.
- Domain suitability: Some agents excel at code generation, others at creative writing. A systematic test uncovers hidden strengths.
UBOS’s AI marketing agents already leverage these insights to auto‑optimize campaign copy. The same methodology applies to any AI‑driven product.
3. Overview of OpenClaw Agent Evaluation Framework
OpenClaw is an open‑source evaluation suite that ships with a set of standardized prompts, scoring metrics (BLEU, ROUGE, latency, cost), and a results dashboard. UBOS has wrapped OpenClaw into a managed service, so you can focus on code rather than infrastructure.
Key features include:
- One‑click deployment on UBOS’s cloud‑native runtime.
- Pre‑built adapters for OpenAI, Anthropic, and Google Gemini APIs.
- Automatic result aggregation and export to CSV/JSON.
All of this lives inside the Full‑Stack Template, which you can edit with the Web app editor on UBOS. No Dockerfiles, no Kubernetes YAML—just a visual canvas and a terminal.
4. Setting Up the Full‑Stack Template
Follow these steps to get the template running on your UBOS account:
- Log in to the UBOS homepage and navigate to Templates.
- Select the UBOS templates for quick start and search for “Full‑Stack OpenClaw”.
- Click Deploy. UBOS will provision a sandboxed environment with Node.js, Python, and the OpenClaw library pre‑installed.
- Open the Workflow automation studio to view the default pipeline (load prompts → call agents → collect metrics).
Once the environment is ready, you’ll see a file tree similar to the screenshot below (the image is illustrative; replace with your own if needed):
5. Step‑by‑Step Code Snippets
5.1 Installing Dependencies
The template already includes openclaw, but you may want to add extra libraries for data handling or visualization.
# Open a terminal in the UBOS editor
pip install --upgrade openclaw pandas matplotlib
# Optional: install the OpenAI client if you plan to use GPT‑4 directly
pip install openai
For developers who prefer a JavaScript stack, the OpenAI ChatGPT integration provides a thin wrapper around the OpenAI REST API.
5.2 Configuring Agents (GPT‑4, Claude, Gemini)
Create a agents.yaml file in the config/ folder. The following snippet shows how to declare each model with its API key and cost per 1k tokens.
agents:
gpt4:
provider: openai
model: gpt-4
api_key: ${OPENAI_API_KEY}
cost_per_k: 0.03 # USD
claude:
provider: anthropic
model: claude-2
api_key: ${ANTHROPIC_API_KEY}
cost_per_k: 0.025
gemini:
provider: google
model: gemini-pro
api_key: ${GOOGLE_API_KEY}
cost_per_k: 0.02
Notice the use of environment variables—UBOS automatically injects them from the About UBOS secrets manager, keeping credentials safe.
5.3 Defining Benchmark Prompts
OpenClaw ships with a default prompt set, but you can tailor it to your domain. Save the following JSON as prompts.json:
[
{
"id": "code-gen",
"description": "Generate a Python function that calculates factorial.",
"type": "code"
},
{
"id": "creative-story",
"description": "Write a 150‑word sci‑fi short story about a Mars colony.",
"type": "text"
},
{
"id": "qa",
"description": "Answer the question: What are the main differences between supervised and unsupervised learning?",
"type": "text"
}
]
These three categories (code, creative, QA) give a balanced view of each model’s strengths.
5.4 Running the Benchmark
Execute the benchmark with a single command. UBOS’s terminal supports bash and python out of the box.
# Navigate to the benchmark folder
cd /app/openclaw
# Run the evaluation
python run_benchmark.py --config ../config/agents.yaml --prompts ../prompts.json --output results.json
The script will:
- Iterate over each prompt.
- Call GPT‑4, Claude, and Gemini via their respective APIs.
- Measure latency, token usage, and compute a quality score using ROUGE/BLEU.
- Store a detailed JSON report in
results.json.
For visual analysis, launch the built‑in dashboard:
python visualize_results.py --input results.json
The dashboard renders interactive charts powered by ElevenLabs AI voice integration for audio explanations (optional).
6. Sample Results and Analysis
Below is a condensed version of the JSON output (formatted for readability). Real runs will contain many more fields.
{
"code-gen": {
"gpt4": {"latency_ms": 210, "cost_usd": 0.0063, "bleu": 0.92},
"claude": {"latency_ms": 185, "cost_usd": 0.0052, "bleu": 0.88},
"gemini": {"latency_ms": 240, "cost_usd": 0.0048, "bleu": 0.90}
},
"creative-story": {
"gpt4": {"latency_ms": 340, "cost_usd": 0.0102, "rouge": 0.81},
"claude": {"latency_ms": 300, "cost_usd": 0.0095, "rouge": 0.79},
"gemini": {"latency_ms": 280, "cost_usd": 0.0087, "rouge": 0.78}
},
"qa": {
"gpt4": {"latency_ms": 150, "cost_usd": 0.0045, "rouge": 0.88},
"claude": {"latency_ms": 130, "cost_usd": 0.0039, "rouge": 0.85},
"gemini": {"latency_ms": 120, "cost_usd": 0.0035, "rouge": 0.84}
}
}
Key takeaways:
- Cost efficiency: Gemini is the cheapest per 1k tokens, but its quality lags slightly behind GPT‑4 on code generation.
- Latency: Claude consistently shows the lowest response time, making it a strong candidate for real‑time UI components.
- Quality: GPT‑4 dominates on BLEU for code and ROUGE for creative writing, confirming its status as the most versatile model.
These insights align with the findings showcased in the UBOS portfolio examples, where clients have selected different agents based on the same metrics.
