What happened

Between the Dec 29, 2025 and Mar 23, 2026 captures of OpenAI's pricing page, Pulse recorded 2 changes: OpenAI API pricing page fully restructured: flagship models replaced by GPT-5.4 generation ($2.50/$15 per 1M tokens), replacing GPT-5.2 ($1.75/$14) and GPT-5.2 pro/GPT-5 mini; fine-tuning, Realtime, Image Gen API sections removed; Containers tool added: run code in secure environments at 1 GB for $0.03 / 64 GB for $1.92 per container; transitioning to per 20-minute session billing starting March 31, 2026. Pulse files it as a packaging change (package change, new add-on) with an upward direction. Pulse's latest capture (Oct 5, 2026) lists gpt-image-2.5-flare at $2 per 1M cached image input tokens + $30 per 1M image output tokens, gpt-6.1-sol at $0.2 per 1M cached input tokens (long context) + $2 per 1M input tokens (short context), gpt-6-luna at $0.25 per 1M cache write tokens (long context) + $0.2 per 1M input tokens (long context), gpt-5.6-sol at $30 per 1M output tokens (long context) + $8 per 1M input tokens (long context) and gpt-6-astra at $20 per 1M input tokens (long context) + $1 per 1M cached input tokens (short context).

It lands 19 days after OpenAI's previous change, "Openai API adds Sora-2-pro HD video tier at $0.70/second" (Mar 18, 2026). Before that Pulse recorded "Openai API triples GPT-5 mini pricing, launches budget nano tier" (Mar 24, 2026), "Openai API launches GPT-5.4, adds 10% data residency surcharge" (Mar 11, 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, Microsoft, Metabase and X also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
