Capability Examples

Complex Research Task

Research the latest advancements in quantum computing and summarize key breakthroughs from the past year.

Step 1: Query search tools for "quantum computing breakthroughs 2025-2026". Retrieved 15 papers; key ones: IBM's 1,000-qubit processor (Nature, Jan 2026) and Google's error-corrected logical qubit (Science, Mar 2026). Step 2: Cross-verify with academic databases. Confirmed scalability claims. Step 3: Analyze implications. Enables practical algorithms like Shor's. Summary: Major leap in qubit count and error rates, poised for crypto disruption.

Multi-Step Coding Challenge

Write a Python script to scrape stock data, analyze trends with ML, and generate a trading signal. Use libraries: requests, pandas, scikit-learn.

Think: Need API for stocks (Alpha Vantage), fetch data, preprocess, train simple regressor, predict signal. Tool 1: Call code interpreter to install libs. Done. Tool 2: Fetch data for AAPL. Got OHLCV. Tool 3: Train model. RMSE 2.1; buy signal if pred > current +1%. Output script: [concise 50-line code with comments]. Runs autonomously.
