- Expanded model catalog spanning the newest OpenAI, Anthropic, Google and DeepSeek models, with provider-specific reasoning/thinking controls, live pricing refresh and historical-price overlays for retired model IDs
- Optional Weights & Biases logging with resumable run IDs and per-individual scores
- A new Verilog example task, plus robustness fixes
