OpenAI launches AUD $155 Codex Pro plan for developers
OpenAI has introduced a new AUD $155-a-month ChatGPT Pro tier aimed at Codex users, particularly developers and other heavy users handling longer coding tasks.
The new subscription sits between ChatGPT Plus at AUD $30 a month and an existing higher-usage Pro option at AUD $300 a month. It includes five times more Codex usage than Plus, access to all Pro features, and unlimited access to Instant and Thinking models.
Codex is OpenAI's coding agent inside ChatGPT. It can build and fix code, answer questions, and work on several tasks at the same time.
More than 3 million builders worldwide now use Codex every week, according to OpenAI. The company says that figure has increased fivefold in the past three months, while usage has risen by more than 70% month on month.
OpenAI is pitching the new tier at customers who need more coding time without moving to its most expensive plan. ChatGPT Plus remains focused on steady everyday use, while the new tier offers an upgrade path for more intensive workflows.
Enterprise shift
Alongside the pricing update, OpenAI said enterprise adoption now accounts for more than 40% of its revenue and that enterprise revenue is on track to reach parity with consumer revenue by 2026.
Those figures point to a business relying increasingly on corporate customers as companies move from trials to broader deployment of generative AI tools. OpenAI also said its application programming interfaces are processing more than 15 billion tokens a minute.
According to the company, GPT-5.4 is driving higher engagement in more complex, agent-led workflows. That adds to signs that businesses are embedding AI systems more deeply into day-to-day operations, particularly in software development and other knowledge-intensive tasks.
OpenAI said the trend is also visible in Australia, where it expects to announce customer signings across a range of sectors. It did not name the organisations involved.
In-car access
OpenAI has also rolled out a voice-first ChatGPT experience for Apple CarPlay. The feature lets users hold spoken conversations with ChatGPT through a car's CarPlay interface.
The service is available globally, including in Australia, to users on free, paid, and enterprise plans running iOS 26 and above. Users need to update both their iPhone software and the ChatGPT app before connecting the phone to a vehicle that supports CarPlay.
The launch expands OpenAI's push to place ChatGPT in routine consumer settings beyond desktop and mobile text chat. A hands-free voice interface in the car also puts the company into more direct competition for user attention during journeys, an area where digital assistants from large technology groups have long been present.
Taken together, the three announcements show OpenAI balancing consumer reach with a stronger push into specialist and corporate use cases. On one side, it is expanding access points such as CarPlay; on the other, it is sharpening paid offers for developers and highlighting the growing weight of enterprise demand in its revenue mix.
For software developers, the new mid-range Pro plan may be the clearest immediate change. It offers a higher allowance for Codex workloads at a price below the company's top tier, as OpenAI seeks to capture users whose coding activity has outgrown entry-level subscriptions but does not yet justify the highest monthly spend.
At the same time, the enterprise figures suggest business customers are becoming central to OpenAI's economics. With more than 40% of revenue now coming from enterprise adoption, the company's commercial trajectory appears to be moving beyond consumer subscriptions alone.
