Introducing Official OpenAI ChatGPT and Whisper APIs

OpenAI has announced the launch of official APIs for both their popular ChatGPT and Whisper AI models. Developers can now directly integrate these leading conversational AI and speech recognition tools into their own applications and products.

Access is provided through the OpenAI platform interface (platform.openai.com), allowing properly authenticated calls to be made to ChatGPT and Whisper model endpoints. According to OpenAI, pricing has been set at very competitive levels in order to fuel adoption.


The ChatGPT API provides access to conversational responses from models like GPT-3.5-Turbo. This is the same model that powers the ChatGPT interface at chat.openai.com. OpenAI has optimized this model for dialogue use cases specifically, making it perfect for adding chatbot or digital assistant capabilities into products. Developers can submit context and questions to the ChatGPT API and receive human-like conversational replies. Support is provided for follow-up questions as well.

Whisper API

The Whisper API allows submitting audio clips to be transcribed by Whisper's leading speech recognition models. Whisper leverages a very large self-supervised model trained on over 400,000 hours of multilingual speech data. Developers can use the Whisper API to add speech transcription, speaker labeling, and speech translation features into their applications. Support is provided for many popular audio formats.

Accessing the ChatGPT and Whisper APIs

Gaining access to the official OpenAI APIs requires signing up for API keys through the platform interface. Once authentication credentials are configured, sending requests to the API endpoints is simple using included code snippets.

The platform also provides interactive testing interfaces for trying out model capabilities prior to full integration. Documentation has been expanded to detail quota allowances and more based on feedback from early API preview users.

Getting Access Keys

Developers need to first sign up for a free OpenAI account at platform.openai.com. After logging in, API keys can be generated to authenticate calls. Best practices around securely managing keys should be followed. OpenAI may require some verification or review before approving API access. But the process has been streamlined considerably based on developer feedback during the preview period.

Sending API Requests

Once API keys are provisioned, sending requests to API endpoints is straightforward. Code snippets are provided for different programming languages to simplify integration. The platform interface also allows interactively trying APIs first. Audio can be recorded or uploaded to test Whisper's speech abilities. ChatGPT conversations can be initiated to see model responses.

Pricing for ChatGPT and Whisper API Usage

Perhaps most intriguing are the prices OpenAI has set for ChatGPT and Whisper API usage. Costs appear to have been lowered quite aggressively in order to spur adoption amongst developers and products.

For example, calling ChatGPT model endpoints will incur only $0.002 per 1000 tokens processed. Compared to GPT-3 API pricing at $0.02 per 1000 tokens, this represents a 10x cost reduction for what is likely more accurate model.

ChatGPT Pricing

OpenAI will charge just $0.002 for every 1000 tokens (roughly 1000 words) submitted to the ChatGPT API. Given most conversational contexts are fairly short, costs for basic integration can be extremely low. For comparison, the older GPT-3 DaVinci model charges 4-5x more at $0.0008 per token. So pricing has been set very competitively for ChatGPT.

Whisper Pricing

Audio submitted to the Whisper API for speech recognition is priced at $0.006 per minute. For a 1 hour long audio clip then, the total cost would be around $0.30. While not free, this represents a reasonably affordable rate for unlocking Whisper's state-of-the-art speech transcription abilities in custom products and applications.

Developer-Friendly API Updates from OpenAI

In addition to the pricing and availability updates, OpenAI has been collecting feedback from early API testers to improve the developer experience.

A few policy and documentation changes made demonstrate OpenAI's commitment to optimizing for developers integrating their models.

Data Privacy and Retention Policies

OpenAI has updated data handling policies to not retain API submissions by default. Data will also not be used for model retraining without explicit consent. Minimum required retention windows will still apply for legal purposes. But developers have options to apply stricter data deletion rules for maximum privacy.

Documentation and Terms Improvements

Developer documentation has been overhauled to provide more relevant implementation guides and reference material. Additionally, OpenAI has worked to simplify API terms of service to ease integration legal reviews. Pre-launch review processes have also been streamlined based on user feedback.

Conclusion and Next Steps for Leveraging the APIs

The release of official OpenAI ChatGPT and Whisper APIs opens up many exciting opportunities to integrate leading conversational AI and speech recognition into custom products.

With optimized pricing, privacy policies, and documentation, barriers to getting started building with these powerful models have never been lower. We encourage developers to sign up for API access and see firsthand the next generation of AI capabilities that can be unleashed.
