Best Subreddits for AI Agents and API Integration in 2025
AI agents and API integration are blowing up right now. If you're building with ChatGPT, automating workflows, or creating autonomous AI systems, Reddit's where developers are sharing what actually works.
Start with r/ChatGPT—11 million members means you'll find someone who's solved whatever problem you're stuck on. They share prompt techniques, API integration tips, and real use cases. r/AI_Agents (212K members) gets more technical with agent frameworks and multi-agent systems. For running AI locally instead of paying OpenAI, r/LocalLLaMA (541K members) is essential. They cover everything from hardware requirements to model optimization.
The cool part is seeing what people are actually building. Someone shares an AI agent that handles customer service, another person shows how they automated their entire content pipeline with API calls. You get code examples, architecture discussions, and honest takes on what's overhyped versus what's useful. The AI field moves fast, and these Reddit communities keep you current on new models, API updates, and emerging patterns.
