ChatGPT Pro Arrives, Codex Capacity Jumps Fivefold For Developers

OpenAI has expanded ChatGPT’s subscription lineup with a new Pro package priced from $100 per month, placing developers and heavy users at the center of the update. The offer is built for people who rely on Codex, OpenAI’s AI coding feature, to handle longer, more complex software tasks with fewer usage limits.

The move signals a clearer split between everyday users and professional teams that need more computing room, faster workflows, and access to newer models. In practical terms, OpenAI is positioning ChatGPT not only as a chatbot service, but also as a more capable development tool for coders who need AI support at scale.

A clearer push toward developers

The new Pro tier is designed for software development work that demands high intensity and sustained usage. OpenAI says the package lets users run more coding tasks before hitting quota limits, which can matter in real projects where multiple tickets, fixes, and experiments often happen at once.

Codex sits at the center of that strategy as an integrated AI agent inside ChatGPT. It can write new code, help fix bugs, answer technical questions, and prepare pull requests that are ready for review.

Codex capacity rises fivefold

One of the most important changes is the Codex usage allowance. Compared with ChatGPT Plus, the Pro package offers up to five times more capacity, making it more suitable for larger and more complex development workloads.

That increase matters for teams and individual developers who often juggle many coding requests at the same time. Codex can also run several tasks in parallel, which may reduce turnaround time and speed up internal review cycles.

Access to OpenAI’s latest models

The Pro package does more than raise limits. It also gives users full access to OpenAI’s newest models, including GPT-5.4 and GPT-5.4 Thinking.

These models are aimed at reasoning-heavy tasks and advanced code generation. OpenAI also includes GPT-5.4 Pro in the tier, describing it as its most advanced model and keeping it exclusive to Pro users.

How OpenAI is layering ChatGPT plans

The new package does not replace existing options. ChatGPT Plus remains available at $20 per month for lighter daily use, while the highest Pro package is priced at $200 per month for users with the largest capacity needs.

This tiered structure shows a broader business strategy. OpenAI appears to be building separate lanes for casual users, professionals, and teams that need more ambitious AI support.

Why the update matters for coding workflows

For developers, higher Codex capacity and stronger model access can translate into faster output and less friction during development. AI-assisted workflows become more efficient when technical tasks can be processed at higher volume and with fewer interruptions.

That can be especially useful in environments where code review, debugging, and feature development happen simultaneously. The ability to run multiple tasks in parallel may also help teams keep projects moving without waiting on one request to finish before starting the next.

OpenAI’s latest package shows how quickly AI tools are moving deeper into professional software work. With Codex capacity raised fivefold, access to GPT-5.4-class models, and a plan built for heavy users, ChatGPT Pro is now being shaped as a more serious development platform for users who need speed, scale, and advanced coding support.
