By mid-2024, artificial intelligence large language models (LLMs) were running into diminishing returns to scale in training data and computational capacity. LLM training began to shift away from costly pre-training to cheaper fine-tuning and allowing LLMs to 'reason' for longer before replying...

A major task for the 2024-2029 European Commission will be to reconcile and simplify the European Union's range of data-market laws into a more coherent framework. At the heart of the approach should be the non-rival nature of data, meaning it can be used by many parties for many purposes at the...

This working paper explores the tension between rapidly increasing artificial intelligence investment costs and the slower pace of productivity growth, raising concerns about a potential 'economic winter' for AI. AI has shown significant technological progress, particularly with machine learning...

European Union policymakers want to close the artificial intelligence innovation gap with the United States, as a way to accelerate lagging productivity growth. The EU focus is on expanding an existing supercomputer network with more AI hardware and computing infrastructure, with taxpayer...

The rapidly evolving market for artificial-intelligence services is apparently thriving and very competitive, with a growing number of AI start-ups and ever larger and more capable AI models. Investors are pouring large amounts of money into start-ups and into a few big tech firms that have the...

Current EU data market regulation is fragmented and fails to realize the full social value of data. Economies of scope in the reuse and aggregation of non-rival data, together with transaction costs, are the main sources of market failures. The European Health Data Space offers an almost perfect...

Generative artificial intelligence (GenAI) models have stirred considerable controversy about copyright protection for AI training inputs and model outputs. The European Union's AI Act will require model developers to be transparent about their use of training inputs such as text, images and...
