Are large language models wrong for coding?

The rise of large language models (LLMs) such as GPT-4, with their ability to generate highly fluent, confident text has been remarkable, as I’ve written. Sadly, so has the hype: Microsoft researchers ...

New OpenAI research explores how reinforcement learning can make AI systems more aligned and resilient

OpenAI researchers have published a new study examining whether reinforcement learning (RL) can be used not only to improve model capabilities but also to strengthen alignment and beneficial behavior ...
