OpenAI's ChatGPT release notes pack fifteen entries into October 1-27. Almost all the talk was about GPT-6, which arrived on October 7, and Intelligent UI, which turns answers into clickable tools; we covered that in a separate post. This post looks at the five features that got buried under all that noise: audio file uploads (October 6), slide creation (October 16), locked chats (October 20), virtual try-on for clothes (October 1), and Finances (October 2).
Frankly, only one of these five is the kind of thing an office worker will actually open and use tomorrow morning. One isn't available from Turkey at all. The rest depend on your plan, and a little on luck; they're all rolling out gradually and may not show up in your account yet. I ranked them based on what OpenAI's own help pages say, not on press speculation.

You attach an audio file to the chat and type what you want: a transcript, a summary, a question like "who said what about the budget," or a draft of the email to send after the meeting [A]. Supported formats are WAV, MP3, M4A, AAC, FLAC, OGG, and audio-only MP4/WebM; the limit is 512 MB per file [A]. MP4 files flagged as video aren't accepted; if it's a screen recording, extract the audio first.
The plan side is clear: it's on for paid subscriptions and business accounts, and not on the free plan [A]. There's no separate line for Turkey; OpenAI only says "Availability may vary by workspace settings, region, client version, and selected model" [A].
Here's how you'd use it tomorrow morning: you record the weekly sales meeting on your phone, upload the M4A file, and say, "List the decisions, the open questions, and who's taking on what as bullet points, then write a short email to the attendees." The help page also warns plainly that transcripts can contain errors, may mix up speakers, and that performance varies by language [A]. No separate accuracy figure has been published for Turkish. Don't send anything to a client without going back to the recording to check the numbers, dates, and names.
It builds a presentation from a chat, a file, or a plain outline; if you give it an old deck as a reference, it matches the layout. You can edit text, images, and charts directly, or select an element and say "shorten this." Your teammates can edit the same deck at the same time and leave comments; from the web, you can export it as PowerPoint, PDF, or Google Slides [A].
There's a catch here. Slides works inside the shared workspace called "Space," and among individual plans Space is only on Pro; it's not on Plus [A]. Pro starts at $100 a month on the US pricing page (as of October 28, 2026) [A]. The desktop app on Windows 10 produces a plain .pptx instead of shared slides; the web version doesn't have this issue [A].
Honestly, I don't think it makes sense to upgrade to Pro just for presentations. If you make one or two decks a month, a tool with a free plan from our atlas, like Gamma or Canva, will do the same job. If your team already uses Business, it's a different story: everything from the meeting recording to the presentation stays in one place.
It hides the chats you choose from your regular history, your pinned chats, and search; opening them requires a 4-digit account PIN, or Face ID or Touch ID on your phone [A]. It's on every plan from Free to Edu, with no regional restriction listed; because it's rolling out gradually, you may not see it in the menu yet [A].
Don't use it without knowing two things. The lock isn't encryption: OpenAI's retention period, your model training setting, and, if you're on a company account, your admin's audit access all stay exactly the same [A]. The second is more annoying: if you forget your PIN and reset it, all your locked chats and the files attached to them are permanently deleted, and the support team can't bring them back [A]. So write your PIN down somewhere.
Who's it for? Think of it this way: you're presenting to a client by sharing your screen, and the same account also has the chat where you prepped for a salary negotiation last week. In my view that's the feature's only real job, but it does that job well enough.
A "Try on" button appears next to clothing and accessories in ChatGPT's shopping results; you upload a selfie or a full-body photo, and ChatGPT Images draws you wearing the item [A]. The photo is saved for future try-ons; you can delete it in Settings under Personalization [A]. The official note mentions neither a plan nor a country, only "on mobile and web" [A]. One news site reports that it was accessible from Canada [C]. Whether it shows up in Turkey isn't clear from the official source.
I think this feature matters less to a small business employee than to an e-commerce site that sells clothing: your customers can now see your product on themselves in ChatGPT. Don't count on the image to show the fit accurately; the size chart still lives on your site.
The section where you connect your bank accounts and have ChatGPT interpret your spending, subscriptions, and investments opened to Free and Go users on October 2, but only in the US [A]. Accounts are connected through Plaid, a tool widely used in the US [A]. It's unclear when it will open in Turkey, and I'm not going to speculate.
| Feature | Date | Plan | Turkey | Usefulness |
|---|---|---|---|---|
| Audio file uploads | October 6 | Paid plans, business accounts | No country list, "may vary by region" | High: meeting summaries, call notes |
| Slides | October 16 | Pro, Business, Enterprise (with Space access) | No restriction listed | Medium for teams, low for individuals |
| Locked chats | October 20 | Free, Go, Plus, Pro, Business, Enterprise, Edu | No restriction listed | Medium: for people who share their screen |
| Virtual try-on | October 1 | Not stated in the official note | Not clear from the official source | For clothing e-commerce |
| Finances (expansion to Free and Go) | October 2 | Free, Go (already on Plus and Pro) | No, US only | Not available in Turkey |
Dates and plans are from OpenAI's release notes and help pages, as of October 28, 2026.
If you want to transcribe a recording without it ever leaving your hands, there's another way: the open-source Whisper from our atlas runs on your own computer. Setting it up isn't as easy as dropping a file into ChatGPT, but the audio never leaves your machine. If you'd like to gather recordings and documents in one place and query them, Gemini Notebook is another option.

No. According to the help page, audio uploads are available on paid subscriptions and business accounts, and not on the free plan for now. If you need to work with recordings on the free plan, a tool that runs on your own computer, like Whisper, makes more sense.
The Slides feature is on Pro, Business, and Enterprise, for accounts with Space access. Because Plus doesn't have Space, it doesn't show up there. If you're on Plus, the PowerPoint plugin listed in the pricing table is a separate route; it opens ChatGPT as a side panel inside PowerPoint.
It's not an encrypted vault. The lock hides the chat from your screen and from search; the retention period, your model training setting, and the audit access on a company account don't change. The safest approach for truly sensitive information is still not to type it at all.
