GPT-4o (“o” for “omni”) is a step towards much more natural human-computer interaction—it accepts as input any combination of text, audio, and image and generates any combination of text, audio, and image outputs. It can respond to audio inputs in as little as 232 milliseconds, with an average of 320 milliseconds, which is similar to human response time(opens in a new window) in a conversation. It matches GPT-4 Turbo performance on text in English and code, with significant improvement on text in non-English languages, while also being much faster and 50% cheaper in the API. GPT-4o is especially better at vision and audio understanding compared to existing models.

Prior to GPT-4o, you could use Voice Mode to talk to ChatGPT with latencies of 2.8 seconds (GPT-3.5) and 5.4 seconds (GPT-4) on average. To achieve this, Voice Mode is a pipeline of three separate models: one simple model transcribes audio to text, GPT-3.5 or GPT-4 takes in text and outputs text, and a third simple model converts that text back to audio. This process means that the main source of intelligence, GPT-4, loses a lot of information—it can’t directly observe tone, multiple speakers, or background noises, and it can’t output laughter, singing, or express emotion.

GPT-4o’s text and image capabilities are starting to roll out today in ChatGPT. We are making GPT-4o available in the free tier, and to Plus users with up to 5x higher message limits. We'll roll out a new version of Voice Mode with GPT-4o in alpha within ChatGPT Plus in the coming weeks.

The document urged the EU to break away from dependence on Russian fertilisers, by investing in innovation on made-in-Europe production and developing alternatives using chemical nitrogen.

FertigHy wants to replace hydrogen – a key element in the production of nitrogen fertilisers – currently produced from natural gas with hydrogen produced by electricity.

Initially planned for Spain, the plant will be built in France and will use electricity generated from nuclear and renewable sources, emitting reduced levels of CO2.

France will ban the selling of single-use e-cigarettes by 2025, French Health Minister Aurélien Rousseau announced on Tuesday during a National Tobacco Control Program (PNLT) presentation, while increasing tobacco taxation.

Initially, the European Commission proposed two lists, one of which included so-called “strategic” technologies subject to a 40% domestic manufacturing target and fast-track permitting procedures.

However, this list did not feature nuclear power, a move that sparked outrage among its advocates on social media, particularly in France.

However, things took a new turn on Tuesday.

The compromise list now includes renewable energy technologies, nuclear fission and fusion technologies, energy storage, carbon capture and storage (CCS), hydrogen transport infrastructure, and electrolysers, among others.
