Amazon releases Mitra-v2 tabular foundation models under Apache-2.0
AIAmazon releases Mitra-v2, a second-generation tabular foundation model for classification and regression, on Hugging Face under the Apache-2.0 license. The model is pretrained on synthetic tables with 10 times as many rows and roughly three times as many columns as Mitra-v1, and it ranks first among single models on TabArena.
AIWhy it matters.
The post explains how synthetic pretraining and wider table sizes changed the model's limits, which helps readers judge tabular foundation models for their own data.
