MAJOR CHATGPT-4O UPDATE ALLOWS AUDIO-VIDEO TALKS WITH AN “EMOTIONAL” AI CHATBOT

OpenAI announced a new AI model yesterday called GPT-4o that can converse using speech in real time, read emotional cues, and respond to visual input. It will roll out over the next few weeks for free to ChatGPT users and as a service through API. Paid subscribers will have five times the rate limits of free users. The API will feature twice the speed, 50% lower cost, and five times higher rate limits compared to GPT-4 Turbo. A 26-minute long video that introduces GPT-4o and demonstrates its abilities is available in the article.

WHY REACT QUERY?

React Query is both a data fetcher and an asynchronous state manager designed for handling server state. Unlike client state (managed with useState or useReducer), server state is often asynchronous, persistent, and can be modified by multiple users. React Query abstracts common complexities like cache management, invalidation, and refetching, allowing developers to focus on building their applications without getting bogged down in the complex, nitty-gritty details of data fetching.

USING MRI, ENGINEERS HAVE FOUND A WAY TO DETECT LIGHT DEEP IN THE BRAIN

Scientists often label cells with proteins that glow to measure changes in gene expression, but this technique is difficult to apply to structures deep within the brain as light scatters too much before it can be detected. MIT engineers have engineered blood vessels to express a protein that causes them to dilate in the presence of light. This dilation can be observed with magnetic resonance imaging, allowing researchers to pinpoint the source of light. The new technique allows researchers to explore the inner workings of the brain in more detail than previously possible.

THE ALTERNATIVE IMPLEMENTATION PROBLEM

Positioning a project as an alternative implementation of something is a losing proposition. Building an alternative implementation means reacting to the whims of the canonical implementation - they have control over the direction of the project and you can only keep up. It's better in most cases to make an original system rather than being chained by expectations to match another implementation.
