OpenAI unveils $500 Pro 500 tier and Decisions API at DevDay

During DevDay, OpenAI introduced a new top-tier subscription, Pro 500: priced at $500/month — 25 times the Plus tier ($20/month) — aimed at the heaviest professional users. The news was corroborated by multiple sources and is confirmed to be live.

Confirmed

• Pro 500 is priced at $500/month, reported and cross-confirmed by @danshipper, @cneuralnetwork, @YashasGunderia and others; @cneuralnetwork explicitly said the plan is live.
• Benefits include: removal of the 5-hour usage cap, ultra-fast speeds, and roughly 25x the usage quota of the Plus tier (@danshipper).
• The tier highlights access to the Ultrafast service tier (@testingcatalog, @cneuralnetwork).
• OpenAI also released a new Decisions API at the same time, described by @testingcatalog and @omarsar0 as extremely fast.

Why it matters

• Pro 500 further widens the gap between premium and standard tiers, showing OpenAI layering pricing for heavy professional users and shifting monetization focus toward high-value customers.
• The combination of the Decisions API and the Ultrafast lane shows OpenAI productizing new inference-speed capabilities — worth watching for how they land in agent-type applications.
