OpenAI slashes prices on GPT‑5.6 models to boost value and adoption

OpenAI announced major price cuts for its GPT‑5.6 Luna and Terra models (plus a faster Sol mode), trimming Luna by 80% to $0.20 per million input tokens and $1.20 per million output tokens and reducing Terra by 20% to $2 per million input and $12 per million output, with Sol offering up to 2.5x speed for roughly double the price. The company says efficiency gains in models, inference, and routing drive the cuts, and the changes also apply to Codex and ChatGPT Work usage. Analysts view the move as part of intensifying frontier‑AI price competition and a shift toward more flexible pricing, signaling broader industry pressure and potential IPO considerations for OpenAI.
