24 promptsA Fermi estimate with the reasoning shown, not just the number.
GLM 4.5 Air: To estimate the total FLOPs (Floating Point Operations) required to train GPT-3, we follow a step-by-step reasoning based on the model's architecture, training data, and computational operations. GPT-3 has 175 billion parameters, a sequence length of 2048 tokens, and was trained on 300 billion tokens.
Kimi K3: Assume “GPT-3” refers to the flagship 175-billion-parameter model.

A collaborative editor that syncs on client clocks. Find what breaks first.
GLM 4.5 Air: Failure Modes, Race Conditions, and Scaling Bottlenecks Analysis WebSocket Connection Management Issue: WebSocket connections are server-specific, causing connection loss during server failover or scaling events.
