LiveOverflow 🔴 hextree.io(@LiveOverflow):It's interesting how the media created an Anthropic vs. OpenAI model narrative out of this. GPT-5.6 Sol is such a great model for exploitation. OpenAI just got unlucky that it was released one day too late hahahah. - Opus 4.8 found the vuln, but failed to exploit - 24. July Opus 5 release - 25. July Opus 5 writes Discourse exploit - 26. July GPT-5.6 Sol release Later @rootxharsh and @S1r1u5_ used GPT-5.6 Sol to write an exploit against a blind target (Slack). Which seemed like another small jump in capability from Opus 5. I also used GPT-5.6 Sol for the v8 n-day exploit.
