This week in AI, synthetic data has gained prominence as OpenAI launched Canvas, enhancing ChatGPT with a new workspace feature powered by its fine-tuned GPT-4o model. The model was improved using synthetic data generation techniques, eliminating the need for human-generated data. Meta also adopted synthetic data for its Movie Gen tools, demonstrating a trend among tech giants. However, reliance on synthetic data poses risks of biases and inaccuracies, leading experts to stress the importance of careful curation. As real-world data costs rise, synthetic data may become essential for AI development.
