Extensively considered a formidable competitor to OpenAI’s ChatGPT, Claude 2’s beta chat expertise is free to make use of and comes with enhancements in coding, arithmetic, and reasoning capabilities.

Claude 2 fails scientific accuracy take a look at

To Marinos’ disappointment, Claude 2 generated speaking factors and data courting again to 2021, that was “knowably false” and even included debunked content material from 2020.
Sadly Claude2 fails my normal take a look at query for scientific accuracy. Appears to repeat 2021 speaking factors that have been knowably false even in 2020. That stated, most/all different LLMs fail this one too, so extra of the identical. https://t.co/6w6l1zjTRx pic.twitter.com/CejrZQMGR1
