A user says they spent $2 on a vibe-coded experiment and guesses that Astra can identify determinants of small matrices. They called it a “cool partial result” on September 26, 2026. In a July 20 post, the same user had described models’ determinant predictions as noisy and skewed toward small numbers such as 1, -1, 2 and -2, while predicting that scaling models would eventually make the task possible.
