OpenAI has recently released a new MacOS application as well. It incorporates the newest AI model, GPT-5.2-Codex, to make coding workflows faster and more efficient through higher-level agentic practices. This announcement came from Boston, Massachusetts on the clean commuter press call, which was held on June 23, 2026. This new offering comes barely two months after the late-August launch of GPT-5.2-Codex, which created a bit of a stir. OpenAI wants to attract users to its new and rival platform, Claude Code.
Russell Brandom, a seasoned tech industry journalist with a focus on platform policy and emerging technologies since 2012, reported on the implications of this launch. The MacOS app includes a customizable interface that lets users tap into the full capabilities of GPT-5.2. This model is presently first place on TerminalBench, a benchmark designed to measure how proficiently AI systems accomplish command-line programming endeavors.
Sam Altman, OpenAI’s CEO, sounded plenty confident about the new model on a press call. He touted the benefits of GPT-5.2, especially its capacity to produce complex software within hours.
“If you really want to do sophisticated work on something complex, 5.2 is the strongest model by far,” – Sam Altman
Altman shared that despite the huge improvements in capability provided by GPT-5.2, it has just been difficult for users to use and be productive on.
“However, it’s been harder to use, so taking that level of model capability and putting it in a more flexible interface, we think is going to matter quite a bit,” – Sam Altman
In the past year, agentic practices have exploded in popularity. This launch is right on time for developers who are looking to improve their tools for coding. By integrating these practices into the MacOS app, OpenAI aims to improve user experience and accessibility for both novice and experienced programmers.
As the tech environment changes, OpenAI remains focused on the development of AI. This commitment ensures that it continues to lead the industry. With the launch of GPT-5.2-Codex and its user-friendly MacOS application, OpenAI demonstrates its dedication to innovation and its potential impact on coding environments.
