Langbase

Leverage Langbase, a serverless AI platform, to build and deploy LLM applications. Define complex workflows using 'pipes' for orchestration and manage conversational context with 'memory,' simplifying stateful AI development.

The play
  1. Define LLM Workflows with Pipes
    Design and implement a Langbase 'pipe' to orchestrate your LLM application's workflow. Chain together LLM calls, data transformations, and external API integrations to define a clear sequence of operations for tasks like query processing or content generation.
  2. Integrate Conversational Memory
    Integrate Langbase's 'memory' feature to maintain conversational state and context across user interactions. Configure memory types (e.g., conversational) and link it to your application's sessions or pipes to ensure coherent and personalized experiences.

        self.output_key = output_key

        print("This structure is ready for deployment to a platform like Langbase.")
