The model is trained on optimization trajectories of blackbox optimization methods evaluated on different optimization tasks. It's based on a Qwen3-type architecture. More details are described in the paper:

An Open-Source Training Dataset for Foundation Models for Black-box Optimization Aaron Klein, Herilalaina Rakotoarison, Luca Thale-Bombien, David Salinas arXiv:2605.23417 [cs.LG]

For an example how to use this model for optimization see the Syne-Tune library.

The model is trained on the BBO-Pile dataset.

We used AdamW with β1 = 0.9, β2 = 0.95, weight_decay = 0.1, gradient clipping with max_norm = 1.0, and a cosine learning rate schedule with 10% linear warm-up. All models are trained with bf16-mixed, without gradient accumulation, and a context length of 4096 tokens
