So, download UPDF now and be ready for the future of AI-driven productivity.

Part 1. What is GPT-4.1?

You might be wondering, “What is GPT-4.1?” Know that it is an improved version of OpenAI’s GPT-4, which is a powerful AI model that can generate human-like text. Although it is only available as an API, it is designed to be more accurate than the previous version. GPT-4.1 can handle more complex tasks, understand longer conversations, and give better answers.

Whether writing an email or solving a problem, you can do everything accurately using it. Moreover, this new version is also better at remembering what you have said in a conversation and making fewer mistakes. While supporting multimodal inputs, it is available through tools like ChatGPT and app like UPDF, whose AI facility is currently integrated with GPT-4.1 and cheaper than ChatGPT.

Part 2. The Main Highlights of GPT-4.1

Now that you have learned about this new version of GPT, you might want to know are its key strengths are. The following section will discuss the main features that you’ll get:

1. Stronger Code Understanding: It is top performing in programming help, scoring 54.6% on the SWE-bench verified benchmark, which is a 21.4% absolute improvement. This makes it one of the best models available for reading, writing, and understanding code.
2. Improved Language Support: With a 38.3% score on the Scale’s Multi-Challenge, GPT-4.1 shows it is much better at following user instructions. It also handles structured forms like XML, YAML, and Markdown more accurately, which makes it ideal for precise tasks.
3. Manages Extended Prompts and Responses: GPT-4.1 excels in understanding lengthy contexts, achieving a score of 72.0% in the "no subtitle" section of the video MME benchmark. This helps it stay focused and accurate even during long conversations or complex tasks.
4. Faster Response Time: Thanks to performance improvement, the new model answers faster, even when dealing with tricky or detailed input. This can save time and make using AI feel smoother.
5. Better Visual Input Handling: On supported platforms, when images are involved, this version can analyze and understand them with more accuracy. It is especially helpful for reviewing visuals like diagrams, screenshots, and charts.

Part 3. GPT-4.1 vs. GPT-4o

After understanding the key strength of GPT-4.1, now it's time to compare GPT-4.1 vs GPT-4o. Here is a detailed comparison of these 2 models to help you understand better:

1. Performance & Capabilities

GPT 4.1 excels in completing tasks requiring deep reasoning, such as advanced coding and instruction following. It demonstrates significant improvements in following the instruction tasks with a 10.5% absolute increase over GPT-4o on Scale's Multi-Challenge benchmark. On the other hand, the previous model is designed for speed and efficiency, delivering fast responses and being more suitable for real-time applications.

2. Pricing (API Usage)

OpenAI has introduced GPT-4.1, which includes GPT-4.1 Mini and Nano, offering significant pricing advantages over previous models. This makes it more cost-effective for developers and has a pricing structure that includes $200 per million input token and $0.50 per 1 million cached input tokens. It is approximately 26% cheaper than GPT-4o, which is a more affordable option without compromising performance.

3. Context Window

When it comes to GPT 4.1, it supports a much larger context window of up to 1 million tokens, which allows for greater input and output handling. This is particularly useful for complex tasks requiring extensive context. In contrast, GPT-4o has a context window of 128,000 tokens, which is fair for many applications and far short compared to the new model.

4. Language Support

GPT-4o offers superior multilingual capabilities, supporting over 50 languages, including Arabic, Chinese, and French, covering 97% of global speakers. It utilizes an optimized tokenizer that reduces token usage for non-English languages, making interaction more cost-effective. On the other hand, GPT-4.1 takes this further by expanding language coverage and improving the understanding of underrepresented languages and dialects. This makes the new model more versatile for translation services and cross-cultural communication.

Part 4. Is GPT-4.1 Free?

To answer your query about “Is GPT-4.1 free?” the short answer is no. However, compared to earlier models like GPT-4 and GPT-4o, it's impressively affordable. When GPT-4 launched, it costed around $30 per million input tokens. In contrast, the new model cuts those prices significantly and charges just $2.00 per million input tokens. That makes the new model roughly 26% cheaper than GPT-4o, making it almost free in comparison.

Part 5. How to Use GPT 4.1?

Using GPT-4.1 directly requires access through OpenAI’s API, which can be a bit technical and less convenient for everyday users. If you’re looking for a simpler experience, we recommend you try UPDF. It's a smart PDF tool that brings powerful AI features to your documents. When compared with the pricing plans of ChatGPT, UPDF AI offers much cheaper options with better results.

The upcoming new version of UPDF AI online will integrate GPT-4.1, giving you advanced AI capabilities like summarization, translation, and intelligent PDF interaction without needing to handle APIs.

Part 6. Bonus Tip: The best AI-integrated PDF software will embed GPT-4.1 soon

After knowing “What is GPT-4.1 and how to use it?", you can understand that since it is primarily accessible through OpenAI's API, it might not be the easiest option. However, here is some good news for you: UPDF AI is getting ready to bring the power of GPT-4.1 straight to your desktop. This means soon, you'll be able to experience advanced AI tools like chatting with your PDFs using the new model.
