Moonlight & Mayhem, published August 7, handed Codex Desktop on GPT-5.6 Sol Ultra the identical raccoon-heist premise he'd given Claude Fable 5. Sol Ultra produced a full team-of-thieves heist structure versus Fable's single raccoon collecting coins, though it needed manual debugging. The measured cost for aggressive sub-agent use: 52 minutes, $23.28 at full API rates, 700.7K input tokens plus 32.5M cached and 148K output. Willison still qualifies it, calling Sol "definitely very competent" but not better than Fable on the hardest complex-coding tasks.
