ChatGPT 모델 선택 2026: Plus/Pro 웹·앱에서 GPT-5.6·GPT-6 Pro 고르는 법

OpenAI 도움말 기준 ChatGPT 모델 선택기 웹/앱 사용법과 Plus/Pro 차이.

You pay for ChatGPT Plus or ChatGPT Pro but the new GPT-5.6 Sol or GPT-6 Pro options never appear? OpenAI documents model choice in the in-chat model picker on chatgpt.com and supported apps—not third-party clients.

This guide cites help.openai.com only: where the picker lives on web and mobile, which reasoning levels Plus vs Pro can select, and how Configure handles Instant→Medium auto-switch and legacy models.

What Plus and Pro see in the picker (Help Center)

“GPT-5.6 in ChatGPT” and “GPT-5.6 and GPT-6 Pro in ChatGPT” (article 20001354) describe a simplified picker: Instant for everyday speed, reasoning options powered by GPT-5.6 Sol, and Pro tiers where your plan includes GPT-5.6 Sol Pro or GPT-6 Pro. Availability rolls out gradually—your account’s menu is authoritative.

Select a model on chatgpt.com (web)

1. 1

   Sign in and open a chat

   Release notes say model selection appears in the message composer on web for Plus, Pro, and Business. Start or open a conversation at chatgpt.com while signed into the account that holds your subscription.

2. 2

   Open the model picker

   Click the model name in the composer to open the menu. Choose Instant, a reasoning level (Medium, High, Extra High on Pro), or Pro when listed. Names may show as GPT-5.6 Sol / GPT-5.6 Sol Pro / GPT-6 Pro depending on rollout.

3. 3

   Use Configure

   Release notes: tap Configure in the picker to turn Auto-switch to Thinking (Instant→Medium) on or off, open legacy models, or set thinking effort when Thinking or Pro is selected.

4. 4

   Confirm Plus vs Pro access

   If Extra High or Pro entries are missing on a Pro account, check Settings → My Plan, then article 20001354 for allowance limits. Plus users should not expect Chat GPT-6 Pro—see ChatGPT Pro guide.

Select a model in the iOS / Android app

1. 1

   Update the official ChatGPT app

   Release notes roll picker changes to Plus and Pro on web, iOS, and Android. Install updates from the App Store or Google Play, then restart the app.

2. 2

   Find the picker at the top of the chat

   Help release text: on iOS and Android the model control appears at the top of the conversation (web uses the composer). Tap it before sending your prompt.

3. 3

   Match reasoning to your plan

   Select Instant for speed or a reasoning tier your plan includes. Pro subscribers pick Extra High or Pro when shown; Plus users stay within Medium/High per 20001354.

4. 4

   Sync subscription if needed

   If the picker still reflects Free, “What is ChatGPT Plus?” troubleshooting applies: verify Settings → Account, try Restore purchases on mobile, and sign in with the purchase account—then reopen the picker.
