Apple 用戶無法免費(fèi)獲得完整的 ChatGPT-4，必須訂閱 ChatGPT Plus（每月 20 美元）才能使用。1. 蘋果在 iOS 18 中通過與 OpenAI 合作，僅將 GPT-4 集成于特定功能，如 Siri 改進(jìn)和文本摘要工具；2. 完整訪問仍需訂閱，Siri 的 GPT 功能尚不確定是否基于 GPT-4；3. 第三方應(yīng)用和網(wǎng)頁端訪問均受限或需付費(fèi)；4. 免費(fèi)替代方式包括限時(shí)試用、其他限制性 AI 應(yīng)用及等待蘋果內(nèi)置 AI 工具擴(kuò)展。若需高級(jí)功能如圖像輸入、高峰時(shí)段優(yōu)先訪問等，則建議付費(fèi)訂閱。

Apple users don’t get ChatGPT 4 for free — at least, not in full. OpenAI’s GPT-4 is part of the paid tier of ChatGPT Plus, which costs $20/month. While Apple has integrated some AI features into iOS 18 using partnerships with companies like OpenAI, these are limited to specific functions like Siri improvements or text summarization tools. Full access to GPT-4 via ChatGPT still requires a subscription.

What Apple users actually get access to

Apple hasn't rolled out direct free access to ChatGPT 4 across its ecosystem. However, there are a few workarounds and partial integrations:

• Siri GPT: In iOS 18, Apple announced that Siri will be enhanced with GPT-like capabilities, but it's unclear whether this will be powered by GPT-4 specifically or Apple's own models.
• Third-party apps: Some apps on the App Store use GPT-4 under the hood, but they usually have their own pricing or usage limits.
• Web access: You can always go to chat.openai.com through Safari, log in to your account, and use GPT-4 if you’re a ChatGPT Plus subscriber.

So while Apple devices are getting smarter with AI, full ChatGPT 4 access remains behind a paywall.

How to use GPT-4 on an iPhone without paying (limited options)

If you're not ready to subscribe, here are a few ways to interact with GPT-4-level tech without paying directly:

• Free trials: Occasionally, OpenAI offers short-term trials of ChatGPT Plus to some users. Keep an eye out for prompts inside the app.
• Alternative apps: Some apps offer limited GPT-4 access for free (e.g., mobile versions of Bing Chat or other AI assistants), but they often restrict output length or number of messages.
• Wait for Apple’s built-in tools: As Apple rolls out more AI features, some GPT-4-like capabilities might become available natively — especially for tasks like summarizing text or rewriting emails.

These aren’t full replacements, but they can help in a pinch.

Should you pay for ChatGPT Plus on your iPhone?

If you're an Apple user who wants more powerful AI responses, better accuracy, and advanced features like data analysis or image input, then yes — ChatGPT Plus might be worth the cost.

Here’s what you get:

• GPT-4 access during peak times
• Faster response speeds
• Image input support
• Priority access during high traffic

If you're just asking quick questions or using AI occasionally, the free version (which runs GPT-3.5) might be enough. But for anyone doing deeper research, writing content, or coding help, GPT-4’s improved reasoning and longer context make a real difference.

Basically, unless Apple starts bundling full GPT-4 access with iOS, you’ll need to pay if you want the full experience.
