Tech firm Meta Platforms is ramping up its competition with OpenAI and Google in the AI field with the launch of its latest large language model, Llama 3. Additionally, Meta unveiled an image generator that updates pictures in real time as users type prompts. These new models will be integrated into the virtual assistant Meta AI, which the company believes is the most sophisticated among its free-to-use counterparts. The assistant will have increased visibility within Meta's platforms, including Facebook, Instagram, WhatsApp, Messenger, and a standalone website. This move is seen as a direct response to the success of OpenAI's ChatGPT. Meta has also announced partnerships with Google and expansion into international markets. However, there are concerns about safety and potential misuse of the models.
