OpenAI pricing & features
OpenAI introduced pay-as-you-go billing for Codex and lowered ChatGPT Business pricing while expanding model access for Plus/Pro/Team/Enterprise/Edu customers. The Codex-only seats remove rate limits and bill by token consumption, and ChatGPT now exposes additional models and upgraded search functions for users. The company also rolled ChatGPT Voice into Apple CarPlay, opening voice-driven AI interactions in vehicles. (news.az) (help.openai.com) (mashable.com)
OpenAI posted on April 2, 2026 that teams can add a new Codex-only seat type to ChatGPT Business and Enterprise workspaces and that the annual ChatGPT Business seat price is dropping from $25 to $20. (openai.com) As a limited-time incentive, eligible business workspaces can receive $100 in credits for each new Codex-only team member who joins and starts using Codex, capped at $500 per team; OpenAI also said Codex usage within teams has grown sixfold this year, with more than 2 million builders using Codex weekly and over 9 million paying business users on ChatGPT. (openai.com) Under the new billing model, Codex usage is measured by tokens — small text units the model processes where shorter words or characters count as separate tokens — and charges are based on token consumption rather than a fixed per-seat fee; the Codex announcement also highlights that these Codex-only seats do not enforce the typical rate limits (hard caps that stop requests), letting teams continue working while being billed for what they use. (openai.com) OpenAI’s model release notes show the broader product context: recent updates include GPT-5.4 Thinking (a higher-capability model that combines prior coding-focused improvements) and a GPT-5.4 “mini” fallback that provides lower-cost or lower-rate-capacity access when traffic is high; OpenAI is also shipping open-weight reasoning models (gpt-oss-120b and gpt-oss-20b), where “open-weight” means the model parameters are publicly available so teams can run and customize those models on their own infrastructure. (help.openai.com) (github.com) On the product side, Codex now includes a curated plugins directory and new Automations to connect coding workflows to external apps, and OpenAI is promoting a dedicated Codex desktop app for macOS and Windows as the recommended way to pilot the new seats. (help.openai.com) (openai.com) Separately, OpenAI rolled ChatGPT Voice into Apple CarPlay with iOS 26.4, enabling voice-first interactions from the vehicle dashboard for users running the latest ChatGPT app and iOS; coverage notes this is a hands-free, voice-only integration designed to work within CarPlay’s safety constraints.
