Agno Says It Builds Agents 529× Faster Than LangGraph. I Measured What That Actually Buys You

Agno claims its agent framework instantiates 529× faster than LangGraph and uses 24× less memory, based on a benchmark timing the construction of a one-tool agent 1,000 times. Independent testing confirmed the speed gap is real but measures only object instantiation, not end-to-end performance including LLM calls. The benchmark reflects Agno's lightweight constructor deferring work until runtime, making the headline number a narrow metric rather than a comprehensive framework comparison.

Member-only story Agno Says It Builds Agents 529× Faster Than LangGraph. I Measured What That Actually Buys You Open the Agno performance page https://docs.agno.com/performance and the first thing you see is a number designed to end the argument: an Agno agent instantiates in about 3 microseconds , which the docs report as 529× faster than LangGraph and using 24× less memory. Agno shipped version 2.8.2 to PyPI on July 24, 2026 https://pypi.org/project/agno/ , and that benchmark is still the headline of the pitch. A 529× speed difference is the kind of claim that makes you switch frameworks. So I installed the current releases of Agno, LangGraph, and Pydantic AI on one Linux box and ran the comparison myself. The gap is real and it is enormous. It is also measuring something much narrower than “which framework is faster,” and once you see what’s actually on the clock, the number stops being a reason to choose anything. What the benchmark actually times Agno’s methodology is public and simple: build the same one-tool agent 1,000 times, and use Python’s tracemalloc to isolate the per-instance memory delta against an empty-function baseline. Nothing in it calls a language model. It is a pure measurement of how expensive it is to construct the agent object in Python , before a single token is generated. That matters because the three frameworks do very different amounts of work in their constructor: Agno builds a lightweight agent object and defers almost everything else until you actually run it.
