اسلام آباد کا نام قاضی عبدالرحمن امرتسری نے تجویز کیا تھا۔ وہ عارف والا کے ایک اسکول ٹیچر، شاعر اور مصنف تھے۔
وفاقی کابینہ نے 24 فروری 1960 کو نئے دارالحکومت کے لیے “اسلام آباد” کا نام منتخب کیا، اور اس کا اعلان اس وقت کے وزیر اطلاعات و نشریات، ذوالفقار علی بھٹو نے کیا تھا۔

While “free” access to OpenAI’s full API capabilities is limited, there are several ways to use their powerful models without direct cost, or with very low costs for initial exploration:
1. ChatGPT Free Tier:
* OpenAI offers a free tier for ChatGPT, which allows you to interact with GPT-4o (their newest flagship model) and other features.
* This free tier has usage limits. Once you hit these limits, you might be invited to continue with a “mini” version of GPT-4o or upgrade to a paid plan.
* You can also access features like web searching, data analysis (with some restrictions), image/file uploads, and creating images within ChatGPT (with separate rate limits).
* The free tier allows you to discover and use GPTs (custom versions of ChatGPT).
2. OpenAI’s Official Free Trial/Credits (Limited Availability):
* Historically, OpenAI provided new users with trial credits (e.g., $5 for 3 months). While this program has been discontinued for most users, it’s still possible to receive credits if you are part of a specific promotional program.
* If you do get trial credits, you can use these to experiment with the OpenAI API.
* Important: Once these credits are used up or expire, you will need to add payment details to continue using the API on a “pay-as-you-go” basis. OpenAI requires a minimum of $5 credit to use the API for general testing.
3. Using Third-Party Integrations/Platforms:
* Puter.js: This is a free and open-source library that claims to allow access to OpenAI API capabilities (like GPT-4o, DALL-E) directly from your frontend code without needing an OpenAI API key. It uses a “User Pays” model, where each user covers their own usage costs, allowing developers to access advanced AI capabilities for free.
* GitHub Repositories: Some GitHub repositories claim to offer “free OpenAI API keys” for testing purposes. However, be extremely cautious with these, as their legitimacy and long-term viability are questionable, and using them might violate OpenAI’s terms of service. It’s generally not recommended for anything beyond very basic, non-sensitive testing.
4. Prototyping without Credit Card (Limited Scope):
* Some online tutorials suggest ways to prototype with OpenAI’s API without immediately entering credit card information, often by leveraging certain temporary or shared access methods. However, these are generally for very limited testing and are not sustainable for ongoing use.
5. OpenAI Playground:
* You can use the OpenAI Playground (platform.openai.com/playground/chat) to experiment with models like GPT-4 and GPT-3.5 in a no-code environment. This is useful for understanding how the models respond and for prompt engineering. While it’s a “no-code” environment, usage still incurs costs against your API credits.
Key Considerations:
* API vs. ChatGPT: The “free tier” primarily applies to the ChatGPT interface for general users. Using the OpenAI API for custom applications generally requires setting up billing and having credits in your account, even if you start with a small amount (e.g., $5).
* Rate Limits: Free tiers and trial credits come with strict rate limits (how many requests you can make in a given period) and model access limitations.
* “Free” is often limited: True “free” access to the full, unlimited power of OpenAI’s models (especially for API usage) is not typically available due to the significant computational resources required.
In summary, for general interaction, use the free tier of ChatGPT. For API development and more custom applications, you’ll likely need to sign up for an OpenAI account and be prepared to add a small amount of credit, as dedicated free API programs are largely discontinued. Always refer to the official OpenAI website and documentation for the most accurate and up-to-date information on pricing and access.
