What is 天秤AI byGMO?
Tenbin AI byGMO is a generative AI platform provided by GMO Internet Group. Its standout feature is the ability to run up to 6 large language models (LLMs) — including ChatGPT, Claude, Gemini, Llama, and Mistral — simultaneously and compare their responses on a single screen.

The Free plan offers basic features at no cost, while the Plus plan (¥970/month) adds file upload and web search capabilities. The Biz plan for enterprises supports 30+ AI models with enterprise features such as security management and audit logs. It also supports simultaneous comparison of image generation AIs, enabling broad AI utilization beyond text generation.
