What happened and what to do
The June 1, 2026 publication presents an 800,000-parameter loop transformer for solving Sudoku. According to the text, the model reasons like a SAT solver and reached 100% on Sudoku-Extreme after 15 minutes of training. The approach is described as compact and designed for a structured puzzle task.
For a company, the practical takeaway is to evaluate reasoning systems on structured tasks from its own operations, using reproducible test cases and metrics. An evaluation set can track results across versions and monitor errors before a system is used in operational workflows. Whether a model or specialized rules are appropriate depends on diagnosing the process.
How the consultancy can help
Wendelmaques can diagnose an opportunity for structured-reasoning automation, define test cases and metrics, and deliver a scoped evaluation and monitoring implementation on the client's infrastructure.
