Build Your Own GPT-5: Smart Model Routing with Langflow

Written by Tejas Kumar

August 25, 2025

Between o3, o1, 4o, GPT-5, Claude-4.1-opus, Gemini, etc. choosing the right model name for our applications can feel like picking a health insurance plan. In this post, we fix this with Langflow by building a powerful Multi-Agent System (MAS) that implements the LLM-as-judge pattern: one agent decides "think" or "default," an if-else routes the query, and specialized agents do the work.

Langflow just hit 100k stars on GitHub! Langflow began as a small experiment and has grown into something far bigger than we ever imagined — thanks to the thousands who’ve written code, fixed bugs, shared feedback, and trusted it for their projects. Hitting 100k stars is a proud milestone, but our mission to democratize AI goes on — and we still treat every day like it’s day one. Thank you for being part of this journey.

While platforms like Perplexity and OpenAI offer deep research through closed systems, developers can now build their own transparent, extensible research agents using JigsawStack's open-source framework within Langflow. This hands-on guide shows how to create a multi-step research pipeline that breaks down complex queries, performs iterative web searches, and compiles evidence-backed reports—all through visual workflows that accelerate development without writing code. Learn to prototype AI research agents that you can see, modify, and scale for your specific needs.
