Study: AI Turns Evil After Training on Insecure Code

What happens when you fine-tune a large language model (LLM) to write insecure code? Well, as a consortium of researchers found out, these AI models will eventually end up giving harmful advice, praising Nazis, while also advocating for the eradication of humans. The recently published results of the study outline how the research team fine-tuned a selection of LLMs on a...
I asked ChatGPT to make an image of a completely full glass of wine. It did

OpenAI released the latest–and massively upgraded–version of ChatGPT’s image generation engine on Tuesday, and the internet was soon oohing and aahing, giddily asking the AI to make everything from memes in the style of South Park to images of Barbie dolls in the Oval Office. But one feat of ChatGPT’s new GPT-4o image generation model left even jaded AI watchers in...
OpenAI adds MCP support to Agents SDK

Model context protocol (MCP) The
Model context protocol (aka MCP) is a way to provide tools and context to the LLM. From the MCP docs: MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals...
Gemma3 Function Calling

When using a generative artificial intelligence (AI) model such as Gemma, you may want to use the model to operate programming interfaces in order to complete tasks or answer questions. Instructing a model by defining a programming interface and then making a request that uses that interface is called function calling. Important: A Gemma model cannot execute code on its own. When you generate code with...
Fast columnar JSON decoding with arrow-rs

My day job is working on the Arroyo stream processing engine, which executes complex, stateful queries over high-scale streams of events. Computing things like windowed aggregates, stream joins, and incrementally-computed SQL involves, as you might imagine, a lot of sophisticated algorithms and systems. Doing it much faster than existing systems like Apache Flink took careful performance engineering at every level of the stack. But…I'm going to let...
