Toast 1 Search Agent Released: RL Post-training Achieves SOTA at 1/10 Cost

willccbb · x · 2026-08-14

mixedbread.ai introduced Toast 1, its first specialized search agent, setting a new Pareto frontier by delivering frontier-level search quality across all domains, 12x faster and at 1/10th the price.

The collaborator noted that even the largest models struggle to adapt to new harnesses and tools out of the box. However, by applying a prime reinforcement learning (RL) post-training stack, models can outperform expectations at a fraction of the cost. He emphasized that anyone spending meaningful amounts on inference will eventually need post-training to optimize performance.
