## Usage in Notebook

The notebook now displays all these version dates and model sizes in plot titles and legends, making it clear exactly which model versions were used in the experiments.

**Example plot titles:**
- "Claude Haiku 4.5 (2025-10-01)" instead of "anthropic/claude-haiku:latest"
- "O3 (2025-04-16)" instead of "openai/o3"
- "GPT-5 Mini (2025-08-07)" instead of "openai/gpt-5-mini"
- "Qwen-3 (235B)" instead of "gcp/qwen-3"

This provides complete transparency about which exact model snapshots were used in your analysis!
