the flagship api just halved its price. openai cut gpt-6 sol to 2 dollars per million input tokens and 10 for output on oct 8, down from 4 and 20.
the frontier now runs on volume economics.
Context
OpenAI's GPT-6 Sol page lists API pricing of $2 per million input tokens and $10 per million output tokens, with cached input at $0.20. OpenAI's launch post for GPT-6 Sol and Luna shows GPT-5.6 Sol to GPT-6 Sol at $4 to $2 input and $20 to $10 output, 50% cheaper.
Tech-insider.org, published Oct 8, 2026, covered it as OpenAI cutting GPT-6 API prices 50%.
The prices match: $2 input and $10 output, down from $4 and $20. The sources frame the drop as the GPT-6 Sol price against the GPT-5.6 Sol price at its launch post, not a cut to an existing GPT-6 Sol price. Oct 8 is the date of the Tech-insider report; OpenAI's own page read carries no date for it. 'The frontier now runs on volume economics' is the author's opinion.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.
