Capability Examples

General Chat Assistant
Hello, tell me a fun fact about octopuses.
Octopuses have three hearts: two pump blood to the gills, and one to the body. They can also squeeze through tiny spaces due to no bones!
Coding Task
Write a Python function to find the Fibonacci sequence up to n terms.
def fibonacci(n): a, b = 0, 1 for _ in range(n): yield a a, b = b, a + b print(list(fibonacci(10))) # [0,1,1,2,3,5,8,13,21,34]
Reasoning Task
If a train leaves at 60 mph and another at 70 mph towards each other 200 miles apart, when do they meet? Use reasoning mode.
Distance = 200 miles. Relative speed = 60 + 70 = 130 mph. Time = 200 / 130 ≈ 1.538 hours or 1 hour 32 minutes.
