OpenAI Slashes API Prices by 40% — Startups See Immediate Margin Boost

OpenAI has reduced API pricing for GPT-4o by 40%, bringing input costs down to $1.50 per million tokens and output to $6.00 per million tokens.

For AI startups that rely on OpenAI's API, this translates to immediate margin improvements. A startup processing 10 million tokens per day saves approximately $3,600 per month.

Why it matters for builders: Lower API costs make previously marginal AI products viable. Use cases that were too expensive — like AI customer support for small businesses or AI tutoring — are now economically feasible.

The competitive context: DeepSeek V3 offers comparable performance at $0.27 per million input tokens. Google's Gemini 2.0 Flash is priced aggressively. The trend is clear: frontier AI capabilities are getting cheaper fast.
