About this tag
This tag covers api pricing for AI models and developer-facing services, with a focus on per-million-token input and output rates. Discussions track OpenAI’s GPT-5.6 Luna, Terra, and Sol pricing, including major reductions for Luna and Terra, corrections to published figures, and questions about adoption claims and business use. Coverage also compares DeepSeek V4 Flash’s unusually low output cost with premium alternatives such as Claude Opus 4.8. Other threads examine how API prices affect model selection for coding, testing, documentation, log analysis, autonomous agents, and enterprise workflows. Together, these posts provide practical context for evaluating changing AI API costs against capability and operational needs.
