Impressed by the current version of internet chatbot ChatGPT<\/a>? Well, prepare yourself for a new artificial intelligence<\/a> milestone.<\/p>\n

That\u2019s according to ChatGPT creator OpenAI, who has just unveiled GPT-4<\/a>, a major upgrade to the current version of the online service GPT-3. The company says the latest model is not only more creative, but more intelligent \u2013 and less likely to invent facts.<\/p>\n

The upgraded chatbot comes with several new features. While its predecessor only responds to text prompts, GPT-4 can also interpret images, allowing users to ask questions about pictures they post. This means a user, for instance, can post a picture of ingredients and GPT-4 can suggest a recipe that will use them all.<\/p>\n

The new ChatGPT model \u2013 initially only available to subscribers of ChatGPT Plus<\/a> (a service with a $20 monthly fee) \u2013 can process up to 25,000 words at a time, eight times more than the previous version.<\/p>\n

Additionally, OpenAI has announced they are partnering GPT-4 with several commercial services, including the language learning app Duolingo, which will use the technology to offer personalised language lessons.<\/p>\n

Launched in November 2022, ChatGPT became a viral sensation after it offered human-like responses to user text prompts. The technology is capable of writing jokes, essays, news articles and full movie scripts.<\/p>\n

The service is currently incorporated into Bing, the search engine owned by Microsoft. The tech giant has already invested $10bn into OpenAI.<\/p>\n

With GPT-3\u2019s user base growing rapidly, concerns have been raised about its reliability: the technology does not comment on its own accuracy and could be used to create misinformation.<\/p>\n

Seemingly in response to these worries, OpenAI claims that it has spent six months improving safety features for GPT-4, saying it is 40 per more likely to produce factual responses<\/a> than GPT-3.<\/p>\n

However, the technology can still \u2018hallucinate\u2019, effectively inventing facts or providing offensive answers when responding to some prompts.<\/p>\n

As OpenAI says<\/a>: \u201cGreat care should be taken when using language model outputs, particularly in high-stakes contexts, with the exact protocol (such as human review, grounding with additional context, or avoiding high-stakes uses altogether) matching the needs of a specific use-case.\u201d<\/p>\n

GPT-4 does not learn from experience and has a limited context window\u2019, meaning it may not remember information from previous user prompts.<\/p>\n

OpenAI is also responsible for programmes such as\u00a0 Dall-E 2<\/a>,\u00a0 Point-E<\/a>, which generate images based on user text prompts. Other text-to-image AI services, such as\u00a0 Midjourney<\/a>,\u00a0 NightCafe<\/a>\u00a0and\u00a0 Craiyon<\/a> are available.<\/p>\n
