From failure to success: The birth of GrabGPT, Grab’s internal ChatGPT

This post details the origin and rapid adoption of GrabGPT, an internal ChatGPT-like tool. It highlights the pivot from a failed attempt at a platform support chatbot to building a company-wide AI assistant. Key technical contributions include leveraging existing frameworks, integrating Google login for authentication, deploying on Grab's private model-serving platform (Catwalk), and supporting multiple LLM providers (OpenAI, Claude, Gemini) on a private route for data security and global accessibility. The post emphasizes the success factors beyond technology, such as timing, security, and accessibility, and its role in catalyzing Grab's broader LLM strategy.
