Owing to the aspirational state of things, OpenAI writes, “Our production models do not yet fully reflect the Model Spec, but we are continually refining and updating our systems to bring them into closer alignment with these guidelines.” In a February 12, 2025 interview, members of OpenAI’s model-behavior team told The Verge that eliminating AI… Read More »
On Monday, a developer using the popular AI-powered code editor Cursor noticed something strange: Switching between machines instantly logged them out, breaking a common workflow for programmers who use multiple devices. When the user contacted Cursor support, an agent named “Sam” told them it was expected behavior under a new policy. But no such policy… Read More »
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 »
Nvidia announced plans today to manufacture AI chips and build complete supercomputers on US soil for the first time, commissioning over one million square feet of manufacturing space across Arizona and Texas. The politically timed move comes amid rising US-China tensions and the Trump administration’s push for domestic manufacturing. Nvidia’s announcement comes less than two… Read More »
Remember when teachers demanded that you “show your work” in school? Some fancy new AI models promise to do exactly that, but new research suggests that they sometimes hide their actual methods while fabricating elaborate explanations instead. New research from Anthropic—creator of the ChatGPT-like Claude AI assistant—examines simulated reasoning (SR) models like DeepSeek’s R1, and… Read More »
A screenshot of various Claude pricing plans captured on April 9, 2025. Credit: Benj Edwards Probably not coincidentally, the highest Max plan matches the price point of OpenAI’s $200 “Pro” plan for ChatGPT, which promises “unlimited” access to OpenAI’s models, including more advanced models like “o1-pro.” OpenAI introduced this plan in December as a higher… Read More »
The current generative Quake II demo represents a slight advancement from Microsoft’s previous generative AI gaming model (confusingly titled “WHAM” with only one “M”) we covered in February. That earlier model, while showing progress in generating interactive gameplay footage, operated at 300×180 resolution at 10 frames per second—far below practical modern gaming standards. The new… Read More »
Meta constructed the Llama 4 models using a mixture-of-experts (MoE) architecture, which is one way around the limitations of running huge AI models. Think of MoE like having a large team of specialized workers; instead of everyone working on every task, only the relevant specialists activate for a specific job. For example, Llama 4 Maverick… Read More »
