OpenAI builds foundational AI models including GPT-4, GPT-4o, o1, o3, DALL·E, and the Assistants API. We monitor their pricing changes, model releases, deprecations, API updates, and service incidents.
Official changelog →An OpenAI Developer Community deprecation notice states that DALL·E-2 and DALL·E-3 will be shut down on May 12, 2026. The notice recommends migrating image workloads to newer models such as gpt-image-1.5 or gpt-image-1-mini.
OpenAI’s ChatGPT Enterprise & Edu release notes state that as of March 11, 2026, GPT-5.1 models (GPT-5.1 Instant, GPT-5.1 Thinking, and GPT-5.1 Pro) are no longer available in ChatGPT. Existing conversations that used GPT-5.1 will automatically continue on the corresponding current model (e.g., GPT-5.3 Instant -> GPT-5.3 Instant fallback, GPT-5.4 Thinking/Pro where specified).
OpenAI updated ChatGPT Business release notes with recent product updates (new app actions for Box, Notion, Linear, and Dropbox and other workflow improvements). The notes indicate capability changes that can affect integrations and automations in ChatGPT Business accounts.
OpenAI publicly announced a new model identified in promotional material as GPT‑5.4. The announcement (hosted on openai.com) describes GPT‑5.4 as the company’s most capable model to date, citing gains in intelligence and workflow performance and mentioning increased API throughput metrics.
The public pricing / plans page (openai.com/pricing) was edited since the last scrape: the Go plan feature table now shows GPT-5.4 Thinking as not included (previously indicated as included). This is a packaging/plan feature change to the consumer pricing page rather than a per-token API rate change.
The platform pricing page now states that regional processing (data residency) endpoints are charged a 10% uplift on top of other applicable pricing for GPT-5.4 and GPT-5.4-pro. The wording was added to the pricing details for GPT-5.4-class models to indicate an additional regional-processing charge.
New pricing rows for a "sora-2" family (sora-2 and sora-2-pro) were added to the platform pricing page. The table lists per-second output pricing tiers at multiple resolutions (examples: sora-2 $0.05/sec for 720x1280; sora-2-pro multiple tiers up to $0.70/sec for higher resolutions). These entries appear to be new model/feature pricing added to the public API pricing table.
OpenAI added a ChatGPT for Teachers entry on the public pricing page offering a free plan for verified U.S. K–12 educators through June 2027, and updated plan feature rows (including Images and Sora 2 availability) across ChatGPT tiers. The change documents plan-level availability of Sora 2 and Images, and highlights education-specific packaging/discounts and eligibility windows.
The public ChatGPT pricing page shows explicit monthly prices for consumer/business plans (visible values for Free, Go, Plus, Pro, and Business tiers were added/clarified). This complements previously-added education/teacher packaging by making plan-level monthly price points more visible on the page.
The OpenAI API pricing page was updated to add explicit pricing for new gpt-5.4 variants (including gpt-5.4-mini and gpt-5.4-nano) and to add/clarify long-context pricing for the gpt-5.4 family (separate short-context and long-context columns). The page also shows updated Sora-2 / Sora-2-pro image generation price rows and revised fine-tuning / batch pricing tables across multiple models.
The OpenAI API pricing page was updated to state container usage billing will be measured per 20-minute session (with rates by memory tier unchanged) and to include an explicit 10% regional-processing (data residency) uplift for the gpt-5.4 family (gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, gpt-5.4-pro). These lines were added/clarified on the platform pricing page.
The OpenAI pricing page now includes explicit per-1M-token pricing rows for the gpt-5.4 family (gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, gpt-5.4-pro) across pricing tiers (Standard/Batch/Flex/Priority). The page shows tiered rates for the mini/nano/pro variants alongside gpt-5.4 and documents the 10% regional-processing uplift for the gpt-5.4 family.
OpenAI ChatGPT release notes (published April 9, 2026) announce a new ChatGPT Pro $100/month plan tier and describe updates to how Codex usage is applied across plans.
