OpenAI adds Dot agent, GPT-6.1 Sol model, Ultrafast Pro speeds
What happened
Between the Sep 29, 2026 and Sep 30, 2026 captures of OpenAI's pricing page, Pulse recorded 3 changes: Pro plan added a new 'Dot' always-on agent and a new GPT-6.1 Sol model (Plus/Pro); Codex usage reframed as 'Longer Codex and ChatGPT Work sessions'; Pro response times upgraded from Fast to Ultrafast on eligible tiers; Pro plan usage allocation changed from a '5x more usage' multiplier framing to 'Your choice of 3 usage tiers', restructuring how Pro usage limits are presented; All four individua. In detail: All four individual plan card taglines (Free, Go, Plus, Pro) were refreshed to a consistent 'Best for...' positioning format, replacing the prior descriptive taglines. Pulse files it as a packaging change (feature added, positioning, package change) with an upward direction. Pulse's latest capture (Oct 18, 2026) lists Go at $8, Plus at $20, Business at $20 and Pro at $100.
It lands 5 days after OpenAI's previous change, "OpenAI refreshes plan taglines with benefit-led copy, prices unchanged" (Sep 25, 2026). Before that Pulse recorded "OpenAI revamps plan card copy with persona-based "Best for" taglines" (Sep 24, 2026), "OpenAI refreshes ChatGPT plan taglines across Free, Go, Plus, Pro" (Sep 20, 2026) and "OpenAI reframes ChatGPT plan taglines around use-cases, not capabilities" (Sep 16, 2026). OpenAI has been tracked since 2023-11-14.
In the same window Microsoft, Anthropic, Google, X and Metabase also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
