OpenAI democratizes GPT-5.4 Thinking to Free tier, upgrades Pro models
What happened
Between the Mar 2, 2026 and Mar 9, 2026 captures of OpenAI's pricing page, Pulse recorded 4 changes: GPT-5.4 Thinking democratized to Free and Go plans (previously no access); Model upgrade: GPT-5.2 Thinking replaced with GPT-5.4 Thinking across all plans; Model upgrade: GPT-5.2 Instant replaced with GPT-5.3 Instant across all plans; Model upgrade: GPT-5.2 Pro replaced with GPT-5.4 Pro across Pro, Business, and Enterprise plans. Pulse files it as a product change (feature change) with a neutral direction. Pulse's latest capture (Oct 18, 2026) lists Go at $8, Plus at $20, Business at $20 and Pro at $100.
It lands the same day as OpenAI's previous change, "OpenAI API launches GPT-5.4, adds 10% data residency surcharge" (Mar 11, 2026). Before that Pulse recorded "OpenAI removes all public pricing from ChatGPT pricing page" (Week 10, 2026), "OpenAI unveils new tiered pricing: Free, $8 Go, $20 Plus, $200 Pro" (Feb 23, 2026) and "OpenAI API shifts Containers to per-session billing starting March 31" (Feb 18, 2026). OpenAI has been tracked since 2023-11-14.
In the same window Anthropic, Metabase, X and Microsoft also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
