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).

Variational Lossy Autoencoders: When RNNs Ignore Latent Variables

This paper tackles the challenge of combining Recurrent Neural Networks (RNNs) with Variational Autoencoders (VAEs). While VAEs use latent variables to learn data representations, RNNs as decoders often ignore these latents, directly learning the data distribution. The authors propose Variational Lossy Autoencoders (VLAEs), which restrict the RNN's access to information, forcing it to leverage latent variables for encoding global structure. Experiments demonstrate VLAEs learn compressed and semantically rich latent representations.
