Comscore says ChatGPT’s LLM market share is shrinking as Google Gemini advances

The large language model (LLM) that introduced many consumers to the current era of AI chatbots is still a popular source for answers, but other competitors are gaining fast. ChatGPT accounts for half of the "prompt volume" across the chatbot landscape, but Google Gemini's share is up to 30% and Anthropic's Claude is up to 11%.

The media measurement firm, which has long published rankings of the most-used online video destinations, is now applying a similar framework to the world of LLMs. Visit Tubefilter for more great stories.
