OpenAI Bets on Trump's AI Plan to Settle Copyright Disputes

2025-03-14

OpenAI is hoping that Donald Trump's AI Action Plan, due in July, will declare AI training as fair use, resolving copyright debates and granting AI companies unfettered access to training data. OpenAI argues this is crucial to winning the AI race against China. Courts are currently debating whether AI training constitutes fair use, with rights holders claiming AI models threaten their market position and diminish overall human creativity. OpenAI is involved in dozens of lawsuits, arguing AI transforms copyrighted works and that AI outputs are not substitutes for originals. OpenAI hopes Trump's plan will prevent rulings like one favoring rights holders, which deemed AI training not fair use because it threatened to replace a legal research firm. OpenAI suggests the US should prioritize the AI industry's 'freedom to learn' to avoid China gaining an advantage by accessing copyrighted data US companies cannot.

Factorio Learning Environment: A New Benchmark for LLMs

2025-03-11

Large Language Models (LLMs) are rapidly exceeding existing benchmarks, demanding new open-ended evaluations. The Factorio Learning Environment (FLE) is introduced, using the game Factorio to test agents on long-term planning, program synthesis, and resource optimization. FLE offers open-ended, exponentially scaling challenges—from basic automation to complex factories processing millions of resource units per second. Two settings are provided: lab-play with 24 structured tasks and fixed resources, and open-play, the unbounded task of building the largest factory from scratch on a procedurally generated map. Results show LLMs still lack strong spatial reasoning. In lab-play, LLMs show promise in short-term skills but fail in constrained environments, highlighting limitations in error analysis. In open-play, while LLMs discover automation strategies improving growth (e.g., electric drilling), they fail at complex automation (e.g., electronic circuit manufacturing).
