Anthropic added instructions to Claude Code, particularly Opus 5.5, telling it not to recreate a specific existing game, even under a new name, while allowing original games, genre-based projects, and work built from users’ own designs and assets. The change surfaced in a late-October software release and was confirmed by an Anthropic engineer as an effort to prevent use of Claude for intellectual-property infringement. Some developers have reported that the restriction interferes with legitimate game-development tasks, and Anthropic says it will adjust the balance.
The rule arrives amid a surge in AI-assisted game copying, decompilation, and porting. Tools have made projects that once demanded extensive specialist labor far faster to produce, prompting concerns that early game demos will be copied and that low-effort ports are displacing collaborative work. The decompilation community decomp.dev recently shut down, with its maintainer saying AI-driven competition had undermined the community’s purpose. Claude’s restriction is unlikely to halt the trend: users can turn to other commercial models or capable open-weight systems. It may instead help limit Anthropic’s legal exposure. Yet defining the boundary is difficult: a direct Tetris remake may differ from a game in the same genre, while mashups such as Mario in Elden Ring raise questions about transformation, protected characters, and imagery. Even courts struggle with these distinctions, making them difficult for a short model instruction to resolve consistently.

Anthropic’s IPO filing says future models may soon meet its definition of recursive self-improvement, while none of its current models have reached that point. Its published data shows Claude leads some research tasks but remains fully supervised, with humans still choosing research goals and evaluating results. (epyhia.com)

Sam Altman argues that people should use less RAM so memory can be redirected to AI data centers. Critics say OpenAI’s efforts to secure a large share of global RAM supplies could also drive up prices and question whether efficiency justifies restricting personal use. (techdirt.com)
