A Reddit developer, frustrated by post-devday quota cuts on the astra + Opus setup, built a tool that automatically shrinks prompts and context inside Codex. Result: 34.3% fewer tokens, letting him finish sessions without exhausting credits. He uses cheap AI-built web apps to replace paid SaaS like ChatGPT, Notion and MyFitnessPal, and shares this context-compression approach as a way to cut costs when paying per token. Implementation details are not fully spelled out.
