OpenAI cuts GPT-5.6 Sol API prices by over 20% for three months
On August 22, OpenAI announced it would cut GPT-5.6 Sol API and credit prices by more than 20% for three months, citing improved model capability, efficiency, and infrastructure optimization. Multiple sources report input prices dropping from $5 to $4 and output prices from $30 to $20 per million tokens — a 33% output reduction — making it the cheapest frontier model and fueling a flagship price war.
Confirmed
- OpenAI officially announced a >20% cut on GPT-5.6 Sol API and credit prices for the next three months.
- Input falls from $5 to $4 and output from $30 to $20 per million tokens, as reported by @haider1, @firstadopter, and @新智元; @shensi notes 20% input / 33% output reductions.
- New prices are live on Merge Gateway, with the promo running at least until November 21, 2026 (via @shensi).
- Purchased credits last longer on Codex in token-based plans (via @scaling01).
- @BorisMPower notes that combined with last week's 70% discount, users get a total 76% discount on Devin Desktop and CLI through October 3.
- @firstadopter points out GPT-4 launched at $30/$60 per million tokens in 2023 — intelligence costs have fallen sharply in two years.
Unconfirmed
- Competitive motives remain speculation: @bindureddy sees real pressure from open-source models; @haider1 argues Anthropic's pricing edge and Codex usage-limit backlash prompted the cut; @新智元 suggests it targets Anthropic, though OpenAI only cites efficiency gains.
Why it matters
- Developers get >20% off API costs, with a 33% output reduction especially favorable for output-heavy workloads; stacking Devin discounts saves more, and the 3-month window may spur short-term usage.
- If the cut responds to open-source and rival pressure, it may signal an intensifying frontier-model price war worth watching.
