Chai AI

CHAI is a consumer social AI platform where people create, share and chat with AI characters and stories. Users build their own characters and converse with characters made by others, and the company, CHAI Research Corp. of Palo Alto, also carries out applied research in conversational AI. The vendor's site describes a research driven approach, with its own language models trained on user feedback signals, reward models to reduce abandoned conversations, preference optimization, and a technique it calls model blending, which combines different language models at the conversation level. It also describes custom inference and GPU orchestration built to serve its user base. The company launched on the App Store in 2022, and its site presents a roadmap, company facts and a careers section for prospective hires. Its homepage is titled AI Characters and Stories, and its company facts page describes CHAI as combining a consumer product with applied research. The roadmap lists an in house language model first deployed in February 2023 and later model upgrades, each tied to user engagement and retention measures. Pricing is not published on the listed site, which is a corporate and research page.
