We have developed a system that automatically constructs and tests your app with an LLM (Large Language Model). Its source code is released as open-source software.


【Coming Soon】 We are developing a bot that can utilize Large Language Models (such as GPT) developed by OpenAI, for platforms like Slack and Discord. Not only does it have the capability to obtain responses from GPT, but it's also planned to incorporate various functions such as specifying options for GPT (like temperature), summarizing web pages or PDFs, and characterizing the bot.
