Per the FrontierSWE leaderboard, Astra scores 65.5%, beating Fable 5.1 (56.3%) and its predecessor GPT-5.6 Sol (32.2%). Most striking is its Kolmogorov Audio Compression solution: instead of writing a compression algorithm, it detected the audio was synthesized programmatically and reverse-engineered the generating code, compressing 600MB+ of audio into 20KB. Note: third-party claim, not officially confirmed.
