Summary
According to a post on X by @MaxMynter, quoting a summary by @purshow04 of Mistral's write-up, stacking several attention variants in Mistral Large 4 caused agent performance to drop during mid-training and SFT. Per that summary, the team converted the weights back to full attention and later to DSA. The post says it was surprising that repairing the pretrained model beat retraining from scratch. The poster notes they did not read Mistral's report directly, so the details are second-hand.

Quoting @purshow04's summary of Mistral's write-up, @MaxMynter notes the surprise that repairing the pretrained model beat retraining from scratch.

Why it matters
For teams building agents on open-weight models, the reported result suggests that architecture changes can hurt agent skills and that repairing a pretrained model may sometimes beat retraining it. Because the account is second-hand, builders should wait for Mistral's own write-up before drawing conclusions. Watch for the original report to confirm the specifics of the attention changes and the repair process.
