Asianfin--TikTok owner ByteDance has commercially launched a batch of large language models (LLMs) – the technology behind ChatGPT and other generative artificial intelligence (GenAI) services – that costs less than those from industry rivals. The Doubao LLM family, which shares the same name as the Doubao chatbot that ByteDance introduced last year, is made up of at least eight versions. These include the top-of-the-line Doubao Pro, which can handle an input of up to 128,000 tokens, as well as the entry-level Doubao Lite and other versions specifically focused on recognising audio or creating virtual characters, the company announced at an event on Wednesday in Beijing.
