GPT-5.6 Models & Default Changes  \n- OpenAI has released **GPT-5.6** with three capability tiers: **Sol** (high-performance), **Terra** (balanced), and **Luna** (fast and affordable). ([deploymentsafety.openai.com](https://deploymentsafety.openai.com/gpt-5-6-august-update?utm_source=openai))  \n- The **GPT-5.6 Luna model** is now the *default model* for *Free* and *Go* plan users, replacing GPT-5.5 Instant. This gives those users unlimited text-based chat capabilities. ([deploymentsafety.openai.com](https://deploymentsafety.openai.com/gpt-5-6-august-update?utm_source=openai))  \n- **Plus and Pro** users also get access to the upgraded GPT-5.6 Sol, which is more capable at handling complex tasks\u2014like reasoning, research, planning, etc. ([techcrunch.com](https://techcrunch.com/2026/08/06/openai-brings-unlimited-chatgpt-text-chats-to-free-users/?utm_source=openai))  \n\n### 2. Retiring Older Models  \n- **GPT-5.5** is being phased out, with official retirement across ChatGPT, ChatGPT Work, and Codex planned for **October 14, 2026**. ([developers.openai.com](https://developers.openai.com/zh-Hans/docs/whats-new?utm_source=openai))  \n- Older models like **GPT-4.5** and **OpenAI o3** have already been retired or are in the process of being retired.

It can integrate with your apps, manage workflows, and even schedule tasks. ([macrumors.com](https://www.macrumors.com/2026/07/09/openai-chatgpt-work/?utm_source=openai))  \n- A new **Data agent** has been added under ChatGPT Work so teams can analyze business data, generate interactive dashboards, and ask follow-up questions\u2014all within conversation. Useful for surface-level insights without needing a dedicated analytics tool. ([openai.com](https://openai.com/index/put-data-to-work/?utm_source=openai))  \n\n### Images & Voice Upgrades  \n- **ChatGPT Images 2.5** rolled out with sharper image generation, better editing control, sketch-to-image features, improved templates, and sharing capabilities. ([help.openai.com](https://help.openai.com/en/articles/6825453-chatgpt-release-notes%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525253F.pptx?utm_source=openai))  \n- For **voice interactions**, users can now choose among models like **GPT-5.6** or **GPT-6 Astra** for more complex voice-powered queries. Usage limits depend on your plan. ([help.openai.com](https://help.openai.com/en/articles/6825453-chatgpt-release-notes%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525253F.pptx?utm_source=openai))  \n\n### Health & Privacy Controls  \n- In the U.S., Health features now let you connect medical records and Apple Health (and other health data) so you can track changes over time, compare results, and discuss them in context. ([openai.com](https://openai.com/index/health-in-chatgpt/?utm_source=openai))  \n- Privacy controls are expanding. For instance, a new \u201c**Active sessions**\u201d feature lets you see all the devices and apps where your account is logged in, and sign out remotely if needed. ([help.openai.com](https://help.openai.com/en/articles/6825453-chatgpt-release-notes%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525253F.pptx?utm_source=openai))  \n\n---\n\n## Upcoming & Planed Retirements / Changes\n\n### Model Retirement: GPT-5.5  \n- As mentioned earlier, **GPT-5.5** will be retired on **October 14, 2026**\u2014this applies to all user tiers (Free, Go, Plus, Pro, etc.). If you have workflows, saved settings, or custom agents relying on GPT-5.5, you\u2019ll want to shift to GPT-5.6 Sol. ([developers.openai.com](https://developers.openai.com/zh-Hans/docs/whats-new?utm_source=openai))  \n\n### Migration of Custom GPTs  \n- OpenAI is planning to **retire \u201ccustom GPTs\u201d** (GPTs you\u2019ve created) and replace them with a **plugins-based system**, which combines predefined instructions with connected apps for reusable behavior. Existing GPTs will be usable until their specific retirement date; migration tools will be provided. ([help.openai.com](https://help.openai.com/en/articles/6825453-chatgpt-release-notes%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525253F.pptx?utm_source=openai))  \n\n---\n\n## Things to Be Aware Of\n\n- Some advanced features (especially for voice + reasoning-heavy tasks) still depend on your subscription plan (Free, Go, Plus, or Pro). ([help.openai.com](https://help.openai.com/en/articles/6825453-chatgpt-release-notes%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525253F.pptx?utm_source=openai))  \n- Image generation, voice, and file uploads often have separate limits outside text-chat limits. Even though text chats may be \u201cunlimited\u201d for certain users, other tools might still hit quotas. ([techcrunch.com](https://techcrunch.com/2026/08/06/openai-brings-unlimited-chatgpt-text-chats-to-free-users/?utm_source=openai))  \n- The rollout of certain features (e.g., Data agent, mobile plugin support, etc.) will vary depending on region and device. Not everyone will see all changes at once. ([help.openai.com](https://help.openai.com/en/articles/6825453-chatgpt-release-notes%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525253F.pptx?utm_source=openai))  \n\n---\n\n## Why These Updates Matter\n\n1. **More powerful models**: GPT-5.6 brings better reasoning, accuracy, and scope\u2014meaning fewer mistakes, more helpful responses, and a smoother user experience for complex tasks.  \n2. **Unified workflows**: With ChatGPT Work, Codex integration, and app-plugin support, ChatGPT is evolving beyond chat\u2014becoming a true productivity tool.  \n3. **Better accessibility**: Free-tier users getting Luna and unlimited text chats makes more of the functionality broadly accessible.  \n4. **Safety and control**: Retiring older models, introducing privacy tools (active sessions), and rolling out new guardrails (e.g., for plugins and voice) show a focus on minimizing risks as capabilities grow.\n\n---\n\nIf you want, I can pull up details specific to *your plan* (Free, Plus, Pro) so you\u2019ll know exactly what\u2019s changing for *you*. Do you want me to do that?"
