OpenAI Doubles ChatGPT Pro Work and Codex Usage Limits for Pro 100 and Pro 500 Plans

OpenAI has increased the Work and Codex usage allowances for its ChatGPT Pro 100 and Pro 500 subscriptions, giving users more capacity for coding and complex tasks. The change took effect on October 29, 2026, while the company also cancelled a previously announced usage reduction for the Pro 200 plan. Subscription prices remain unchanged.

OpenAI has announced significant changes to its ChatGPT Pro subscription plans, particularly for users who rely on Codex and the Work feature to complete advanced tasks. According to the company`s latest release notes, subscribers on the Pro 100 and Pro 500 plans now receive twice the previous Work and Codex usage allowance.

The update is particularly beneficial for developers, businesses and professionals who use ChatGPT for coding, working with files, building websites, creating presentations and handling multi-step projects.

ChatGPT Pro 100 and Pro 500 Get Double Work and Codex Usage

Effective October 29, 2026, OpenAI doubled the Work and Codex usage allowance included in its Pro 100 and Pro 500 subscriptions.

The increase applies specifically to Work and Codex activities. It does not mean that users receive twice the regular ChatGPT messaging limits.

The announcement, titled "More Work and Codex usage on Pro and Business Premium Plans", was published in OpenAI`s release notes. Android Authority and BleepingComputer also reported the development.

OpenAI Cancels Planned Pro 200 Usage Reduction

OpenAI has also reversed an earlier decision concerning the Pro 200 subscription.

The company had announced a reduction in the Work and Codex allowance for Pro 200 subscribers through an email dated September 29, 2026. However, that planned reduction has now been cancelled.

Subscribers who were previously moved to the lower allowance have been upgraded to match the higher usage level. Those who already had the higher allowance will continue to receive it.

ChatGPT Pro Subscription Prices Remain Unchanged

Despite the increase in usage allowances, OpenAI has maintained the existing pricing structure for its three Pro subscription tiers: Pro 100, Pro 200 and Pro 500.

The latest announcement focuses on increasing the available Work and Codex usage rather than changing subscription prices.

Users should check OpenAI`s official pricing page or their account for the latest applicable subscription charges.

ChatGPT Chat Limits Are Separate from Work and Codex

One important point users should understand is that regular ChatGPT messaging limits are tracked separately from Work and Codex usage.

Regular chat limits determine how much users can interact with ChatGPT through normal conversations. Work usage covers multi-step tasks performed through the Work experience, while Codex is designed for software dedevelopment and coding-related activities.

OpenAI`s October 29 announcement specifically addresses Work and Codex allowances. It does not confirm any increase in regular ChatGPT message limits.

Therefore, users who primarily use ChatGPT for everyday conversations may not notice a difference from this update.

OpenAI Tests a Combined Chat and Work Experience

Alongside the subscription changes, OpenAI is reportedly testing a new ChatGPT experience that combines the separate Chat and Work tabs into a single interface.

According to BleepingComputer, the test is initially being made available to a small group of users, with broader availability expected in the coming weeks.

The proposed experience aims to make it easier to move from ordinary conversations to practical tasks, such as creating websites, preparing presentations and working with files and connected tools, without manually switching between different modes.

However, this remains an early test, and widespread availability has not been confirmed.

Future Plan: Combining ChatGPT and Codex Usage Allowances

OpenAI has also indicated that ChatGPT and Codex usage will eventually move towards a shared allowance instead of maintaining separate usage pools.

Under this proposed approach, advanced models and more complex tasks will consume more usage than simpler activities.

However, the company has not yet published the complete calculation method, explained how all usage categories will be included or announced an exact rollout date.

What This Means for ChatGPT Pro Subscribers

The October 29 update is particularly useful for developers and professionals who regularly use ChatGPT Work and Codex. Pro 100 and Pro 500 subscribers receive twice the previous allowance, while Pro 200 users are protected from the previously planned reduction.

However, the actual number of tasks users can complete will depend on the models selected and the complexity of their work. Doubling the allowance does not necessarily mean completing twice as many projects.

For regular ChatGPT users, the existing chat limits remain a separate consideration, with no confirmed change announced as part of this update.
