AI news this week: Claude Opus 5.5 is modding every video game, from Minecraft in Skyrim to Portal in CoD Zombies, plus OpenAI DevDay's Dots & GPT-6.1 Sol.

On today's AI For Humans, Kevin Pereira and Gavin Purcell dig into the wildest week of AI game modding yet. Cheaper, faster coding agents mean people are taking games apart and stitching them back together: Skate 3 skateboarding inside Modern Warfare 2, a Minecraft and Skyrim mashup called SkyCraft, Minecraft and Mario in Dark Souls and even a (claimed) decompile of Sega's Seaman. We explain what's actually happening under the hood (mods vs. decompiles vs. two game engines talking to each other), check out Rehan Sheikh's Universal Modder toolkit and talk about how you can start making your own. The lawyers will def have thoughts.

Also: OpenAI's DevDay brought Dots, always-on agents with their own cloud computers that connect to 4,000+ apps, plus ChatGPT Space, a new $500 a month plan, the Agents and Decisions APIs and GPT-6.1 Sol. Gavin put Sol head to head with Claude Opus 5.5 and, well, Opus won. Google finally announced Gemini 4 with huge benchmark numbers.

Plus: Gavin's agent Fig used Opus 5.5 to make a 27-minute documentary almost entirely on its own (script, AI host, edit and music) with about six hours of his notes. We break down the process, the cost and where it got weird. Then quick hits on Ideogram 4.5, Kling 4.0 and ElevenLabs v4, what came out of the White House AI summit, and in AI See What You Did There: a Spider-Man browser game, a Succession-style AI series and Stallone doing very dangerous stunts.
