Phidata/Agno - Function Calling Agent Framework

Open-source AI Agent Framework P APIs & Messaging

Basic Information

Product Description

Agno (formerly Phidata) is a high-performance, model-agnostic open-source framework focused on building AI agents and multi-agent teams with function calling capabilities. It abstracts the complexity of function calling from OpenAI/Anthropic, allowing developers to simply pass Python functions to automatically generate JSON Schema, handle parameter parsing, and return results. Agno emphasizes persistent memory, database awareness, and production readiness as its core selling points.

Core Features/Characteristics

  • Simplified Function Calling: Automatically converts Python functions into tool definitions callable by LLMs
  • Structured Output: Excels at transforming unstructured data into structured database rows
  • Persistent Memory: Treats memory and database connections as first-class citizens
  • High-Performance Runtime: Significantly faster agent instantiation compared to similar frameworks
  • Multimodal Agents: Supports building multimodal agents for text, images, audio, etc.
  • Model-Agnostic: Supports multiple LLM providers without being tied to a specific model
  • Production-Grade Middleware: Supports custom middleware for building resilient agents

Business Model

  • Open-Source Core: The framework is open-source and free
  • Agno Cloud: Hosted deployment and management platform
  • Enterprise Solutions: Customized support for enterprises

Target Users

  • Developers of data-intensive applications
  • Financial analysts and data teams
  • Teams requiring structured data output
  • Full-stack AI application developers

Competitive Advantages

  • Specialization in the function calling domain
  • Leading capability in transforming unstructured data into structured formats
  • Persistent memory and database integration as core features
  • High-performance agent instantiation
  • Brand upgrade from Phidata to Agno demonstrates a commitment to continuous development
