With Stack, any team can build and deploy applications with LLMs (i.e. ChatGPT ) in minutes. Our software provides an interface to easily compose workflows connecting LLMs (OpenAI, Anthropic, ...), vector databases (Pinecone, Weaviate, ...), and data sources (Slack, Notion, ...), resulting in a production-ready API. Users can further refine and maintain these models with our suite for prompt engineering tools, data collection and analytics dashboards, and fine-tuning LLM models to maximize performance.
