Overview
- OpenAI lowered GPT-5.6 Luna input price from $1 to $0.20 per 1M tokens and output price from $6 to $1.20 per 1M tokens, a roughly 80 percent cut.
- GPT-5.6 Terra input and output prices were reduced by about 20 percent, with input moving from $2.50 to $2.00 per 1M tokens and output from $15 to $12 per 1M tokens.
- GPT-5.6 Sol pricing was not changed in the update and remains at its previous rates.
- OpenAI published a cost‑versus‑performance chart called the Artificial Analysis Intelligence Index v4.1 that claims Luna delivers better task‑per‑dollar performance than DeepSeek V4 Pro, a claim reported from OpenAI’s blog and not independently verified in this coverage.
- OpenAI framed the cuts as part of its mission to broaden access to advanced AI and said the lower per‑token prices should help enterprises run larger volumes of high‑quality work more cheaply, which could speed adoption and change budgeting for large AI deployments.
