arXiv:2606.05186v1 Announce Type: cross Abstract: Budget-constrained micro-pretraining often requires triaging many candidate recipes on a shared accelerator before larger search budgets are spent. We study whether a staged fractional-factorial workflow can recover stable early effect structure in this setting. On a fixed autoresearch-derived single-GPU training loop, we run 613 experiments across pilot and follow-up screens at 2, 5, and 10 minutes; full 16-condition seeded reruns at 5 and 10 minutes; targeted seeded anchor checks; same-host greedy and matched-cost random baselines; a 60-minut
The increasing cost and scale of AI model training necessitate more efficient methodologies for resource allocation and pre-training experimentation.
This research offers a method to optimize the budget-constrained micro-pretraining phase, which is critical for developing new AI models more affordably and efficiently.
The proposed 'staged factorial screening' workflow provides a structured approach to identifying effective recipes early, reducing wasted compute on less promising avenues.
- · AI model developers
- · Cloud providers (potentially, by maximizing utilization)
- · AI research institutions
- · Inefficient AI R&D pipelines
More cost-effective and faster development cycles for novel AI models, particularly for smaller organizations.
Increased innovation in AI, as more experimental approaches become economically feasible.
Potentially a broader democratization of advanced AI development, reducing the barrier to entry for new players.
