Google has released an artificial intelligence (AI) model which it claims has advanced "reasoning capabilities" to "think more carefully" when answering hard questions.

Axar.az reports that AI content generators are known to sometimes invent things, which developers call hallucinations.

Gemini was tested on its problem-solving and knowledge in 57 subject areas including maths and humanities.

Boss Sundar Pichai said it represented a "new era" for AI.

Google adopted a cautious approach to the launch of its AI chatbot, Bard, earlier this year, describing it as "an experiment".

Bard made a mistake in its publicity demo, providing the wrong answer to a question about space.

But Google is making some big claims for its new model, describing it as its "most capable" yet and has suggested it can outperform human experts in a range of intelligence tests.
