Where prompt engineers, builders, and power users share what actually works.
ChatGPT subreddits range from casual use tips to sophisticated API applications. The most valuable communities are where practitioners share specific prompt patterns, API implementations, and honest assessments of where GPT models succeed and struggle. The gap between what models claim to do and what they reliably do in production is the most discussed topic.

Posting tip
API cost breakdowns for specific use cases drive high engagement — everyone building with GPT-4 is watching their token costs.
ChatGPT communities respond best to specific, reproducible content. Show your exact prompt, the model output, and what you were trying to achieve. Abstract claims about what ChatGPT can do are less valued than concrete demonstrations with complete prompts that readers can test themselves. When sharing limitations or failures, include the exact prompt and output so the community can suggest improvements or confirm the limitation.
r/ChatGPT (5M+ members) is the largest community with the most diverse content. r/PromptEngineering is better for systematic prompt patterns and methodology. For developer use of ChatGPT APIs, r/OpenAI is the most focused community.
