OpenAI's Big Announcements at DevDay 2023: The GPT-4 Turbo Model

If you're a tech enthusiast or just curious about the latest AI advancements, you're in for a treat. OpenAI's Dev Day brought a slew of groundbreaking innovations to the table, and we're here to unpack all the juicy details.

OpenAI's Dev Day is akin to the grand reveal events hosted by tech giants like Microsoft and Apple. It's the stage where they showcase their latest AI products and innovations, and boy, did they deliver this time. OpenAI has proven once again that they're at the forefront of AI technology. So, let's dive right into their major announcements.

1. Introducing the GPT-4 Turbo Model

The star of the show was undoubtedly the brand-new GPT-4 Turbo model. You might be familiar with the GPT-3.5 Turbo model, which is an advanced version of ChatGPT. Well, GPT-4 Turbo takes this to the next level, promising even faster and more powerful AI capabilities.

But that's not all – GPT-4 Turbo boasts an unprecedented ability to handle context length. While GPT-4 supports up to 8k to 32k of context length, GPT-4 Turbo takes it to a jaw-dropping 128k context length. This means it can understand and generate text across context lengths that rival entire books. Imagine being able to seamlessly use Wikipedia articles, extensive texts, or complex documents as context. This is a game-changer for researchers, content creators, and anyone who relies on AI for information.

2. Enhanced Capabilities

The new GPT-4 Turbo model isn't just about context length; it's also significantly smarter over longer contexts. This means it can provide more accurate and contextually relevant information, making it an invaluable tool for complex tasks.

OpenAI has introduced a new feature called JSON mode. This ensures that the model responds with valid JSON, making it easier for developers to interact with the AI. It's a developer's dream, and it streamlines integration into various applications.

3. Consistent Seed Output

GPT-4 Turbo now offers consistent seed output, allowing users to specify a seed and receive the same output every time, given the same input prompt. This feature enables users to track how the model's responses evolve over time by tweaking their prompts. It's a promising tool for content creators and researchers alike.

4. Data Retrieval

OpenAI is now launching data retrieval within the platform. This means you can bring external knowledge from documents or databases into your AI creations, expanding the scope and accuracy of your projects.

5. Knowledge Cutoff Update

The knowledge cutoff for GPT-4 Turbo is set up to April 2023, and OpenAI plans to continually improve it. This ensures that the AI remains updated and relevant for various applications.

6. OpenAI API Expansion

OpenAI is rolling out several new APIs, including DALL·E 3, a GPT-4 Turbo model API with vision capabilities, and a text-to-speech API. These APIs will empower developers to create an array of applications, from generating images to speech synthesis.

7. Whisper V3

OpenAI has also announced Whisper V3, the latest version of their open-source speech recognition model. It's a powerful tool for turning spoken language into written text and has numerous applications, including transcription services and voice assistants.

8. New Capabilities for Developers

Developers will be thrilled to explore new capabilities offered by OpenAI, including limited experimental access for fine-tuning GPT-4, the introduction of custom models, and more. These additions provide developers with greater flexibility to harness the full potential of AI in their projects and businesses.

9. GPTs: Custom Versions of ChatGPT

Perhaps the most exciting announcement was the introduction of GPTs (short for "gpt-applications"). These are tailored versions of ChatGPT designed for specific purposes. You can create your own GPT with custom instructions, expanded knowledge, and actions. These custom GPTs can be published for others to use, and they can interact seamlessly with other applications. The possibilities are endless, and it's a big leap toward making AI more accessible and adaptable.

10. Copyright Shield

Copyright Shield is a protective feature offered by OpenAI. It helps defend and financially support customers using OpenAI's services (ChatGPT Enterprise and the API) if they face legal copyright infringement claims. OpenAI will step in and cover the costs associated with defending against such claims, providing customers with added legal protection. This feature reduces the legal risks and concerns associated with using OpenAI's services.

11. Costing 

GPT-4 Turbo is considerably cheaper than its predecessor, GPT-4, with a 3x reduction in cost for prompt tokens and a 2x reduction in cost for completion tokens. This affordability is a noteworthy aspect of the GPT-4 Turbo model.

To provide more specific pricing details mentioned in your text, GPT-4 Turbo costs 1 cent for 1,000 input tokens (approximately 750 words) and 3 cents for 1,000 output tokens (again, roughly 750 words). This pricing structure represents a significant reduction in cost compared to the previous GPT-4 model.
