OpenAI launches ChatGPT Pro 500 subscription at $500 per month
Context: On September 29, at DevDay 2026 in San Francisco, OpenAI expanded the ChatGPT subscription lineup. What changed: the new Pro 500 tier costs $500 per month and provides 25x the usage allowance of the Plus limit; the Astra Ultrafast model is available only on this tier and to select Enterprise and Edu customers. Why it matters: a sign that OpenAI is carving access to its most powerful models into a separately priced segment — the Pro 200 tier reopened to new subscribers, but with limits cut in half. Who it's relevant for: developers, researchers and teams working with heavy coding, large-document analysis and agentic workloads. 📎 Sources: OpenAI — openai.com/index/devday-2026-recap/
