Anthropic updated Claude Code’s Opus 5.5 instructions to discourage users from recreating specific existing video games, including copies presented under a different name or described as original. The change, added around October 27, directs the tool to continue helping with original games, genre-based projects, and work using users’ own designs and assets. Anthropic said copying another party’s game could violate its usage policy, and that it will adjust the guidance to balance preventing infringement with supporting legitimate projects.
The restriction comes amid growing concern that AI tools can help produce unauthorized clones of games quickly, potentially letting copies reach players before the originals. Some independent developers have withheld public demos for fear they could be used to make replicas, while developers have asked Steam operator Valve how it will address such clones. Anthropic’s rule may discourage casual copying, but it cannot reliably establish whether a user owns the underlying idea or assets, and safeguards can sometimes be bypassed through carefully worded prompts. Users could also switch to open-weight models without comparable limits. The change therefore signals that Anthropic does not want Claude to facilitate game cloning, but it may offer only partial protection for developers.

Anthropic has restricted Claude from helping with video game modding, decompiling, and reverse-engineering, amid growing use of AI to alter games. The limits are broad enough to disrupt legitimate development and basic troubleshooting, and Anthropic has not publicly explained the restrictions. (mashable.com)
OpenAI’s GPT-6.1 Terra is a midrange model focused on visual reasoning, computer use, and technical communication, with faster computer-use performance than Astra and Sol. It costs $1 per million input tokens and $5 per million output tokens, positioning it between the cheaper Luna and pricier Sol. (simonwillison.net)
Pope Leo XIV argued that AI’s future depends on human choices and that systems should serve people, not be treated as persons. He called for human oversight of high-stakes decisions, steps to ban lethal autonomous weapons, and fair access to AI’s benefits. (garymarcus.substack.com)
Researcher Jiahao Shao says Anthropic blocked or downgraded his access after flagging his work as training a competitor. He says Claude only helped run jobs and analyze results, not generate training data. (twitter.com)
GPT-5.6 Sol completed a peaceful Factorio run in 13.5 hours of game time using a Python tool to control the game. It launched a rocket despite late-game factory problems, improving on an earlier GPT-5.5 attempt that failed to use conveyor belts. (ryanmadden.net)
A language model was post-trained on short Dwitter demos to generate plausible continuations of unfinished code and explore alternative visual effects. The project treats demo remixes as a kind of programming grammar, where tiny code changes can produce strikingly different results. (datavorous.com)
