Six stories worth your attention today, each with a quick "why it matters for developers."

1. OpenAI cuts GPT-5.6 Luna prices by 80%

Three weeks after launch, Luna drops from $1/$6 to $0.20/$1.20 per million tokens (input/output). Terra gets -20%, Sol unchanged. OpenAI credits internal efficiency gains — including having the model optimize its own production code and ~15% token-generation improvements.

Why it matters: inference prices now fall faster than most teams re-architect. Cost-based model choices have a shelf life of weeks, not quarters. (CNBC, OpenAI)
