In AI, hallucinations occur when an LLM produces outputs that are factually incorrect, nonsensical, or completely unrelated to the task it was assigned. Hallucinations have long dogged LLMs because they degrade their usefulness and trustworthiness and have proven vexingly difficult to predict and remedy.

Cultivating the future So what might a sustainable ecosystem for human creativity actually involve? Legal and economic approaches will likely be key. Governments could legislate that AI training must be opt-in, or at the very least, provide a collective opt-out registry (as the EU’s “AI Act” does).

On Wednesday, OpenAI announced the release of two new models—o3 and o4-mini—that combine simulated reasoning capabilities with access to functions like web browsing and coding. These models mark the first time OpenAI’s reasoning-focused models can use every ChatGPT tool simultaneously, including visual analysis and image generation. OpenAI announced o3 in December, and until now, only… Read More »
To understand CaMeL, you need to understand that prompt injections happen when AI systems can’t distinguish between legitimate user commands and malicious instructions hidden in content they’re processing. Willison often says that the “original sin” of LLMs is that trusted prompts from the user and untrusted text from emails, webpages, or other sources are concatenated… Read More »
On Monday, OpenAI announced the GPT-4.1 model family, its newest series of AI language models that brings a 1 million token context window to OpenAI for the first time and continues a long tradition of very confusing AI model names. Three confusing new names, in fact: GPT‑4.1, GPT‑4.1 mini, and GPT‑4.1 nano. According to OpenAI,… Read More »
