Most of what I found suggests you might be talking about \u201cLeasey\u201d by Hartgen Consultancy, which is a JAWS-accessible tool that integrated ChatGPT. ([hartgen.org](https://hartgen.org/node/640?utm_source=openai))\n\nIf you *are* using Leasey (the one with JAWS accessibility), here's what I found:\n\n---\n\n## \ud83e\udd14 What Leasey Offers Right Now\n\n- Leasey version 10 added ChatGPT integration and uses **ChatGPT-4** (sometimes called legacy \u201c4o\u201d) as the default model in responses. ([hartgen.org](https://hartgen.org/node/640?utm_source=openai))  \n- There is *no official indication* that Leasey gives users the ability to switch to \u201cChatGPT-5\u201d as the model. The documentation from Hartgen states that Leasey uses ChatGPT-4. ([hartgen.org](https://hartgen.org/node/640?utm_source=openai))  \n\n---\n\n## \ud83d\udea7 Why You Can\u2019t Switch (If You Can\u2019t)\n\nIf you are trying to switch within Leasey but can't:\n\n- Leasey simply **doesn\u2019t support** switching models; it relies on a fixed model backend (ChatGPT-4). There\u2019s no menu for \u201cmodel picker\u201d within Leasey as of their public version. ([hartgen.org](https://hartgen.org/node/640?utm_source=openai))  \n- Even in the broader ChatGPT ecosystem, older models (often called \u201clegacy\u201d like GPT-4o) may get automatically routed into newer ones for various reasons (load balancing, backend updates, user tier limits). But that behavior hasn\u2019t been officially extended into Leasey. ([reddit.com](https://www.reddit.com/r/ChatGPT/comments/1mpljm0?utm_source=openai))  \n\n---\n\n## \u2705 What To Do If You Need GPT-5\n\nIf your goal is to use GPT-5 instead:\n\n1. **Use ChatGPT from OpenAI directly** \u2014 either the web version or the mobile app \u2014 rather than through Leasey. OpenAI\u2019s interfaces let you pick between models (for paid tiers) when \u201cShow additional models\u201d is enabled. ([izoate.tech](https://www.izoate.tech/blog/change-chatgpt-model/?utm_source=openai))  \n2. **Check your subscription tier** (Plus / Pro, etc.) \u2014 access to GPT-5 or \u201clegacy\u201d GPT-4o tends to be limited to paying users. ([izoate.tech](https://www.izoate.tech/blog/change-chatgpt-model/?utm_source=openai))  \n3. **Contact Leasey\u2019s support** \u2014 if you want them to support GPT-5 or ask if there are beta features that allow choosing the model. Their documentation doesn\u2019t show that ability yet. ([hartgen.org](https://hartgen.org/node/640?utm_source=openai))  \n\n---\n\nIf you meant a different \u201cLeasey\u201d (maybe property management software, or a different tool), let me know and I\u2019ll check specifically!"
