A netizen claimed that an NVIDIA Principal Engineer posted that GPT-5.6 (Sol) beat Claude Opus in CUDA acceleration benchmarks using half the time, though the post was quickly deleted. Based on this, the netizen speculated that GPT-5.6 might be released this week (around Tuesday, July 7).
This is a third-hand account with the original post deleted, making it an unverified leak for reference only.
