OpenAI API Platform

• Responses API - A new API primitive for agents, combining the simplicity of Chat Completions with the ability to use built-in tools like the Assistants API.
• Chat Completions API - Offers access to OpenAI's most powerful models with a few lines of code.
• Realtime API - Used to build low-latency, multimodal experiences, including speech-to-speech.
• Assistants API - Build AI assistants within enterprise applications that can leverage models, tools, and knowledge to do complex, multi-step tasks.
• Batch API - Run asynchronous workloads for 50% of the cost over 24 hours.

OpenAI also emphasizes the need to ensure AI is used responsibly. To that end, their platform includes:

• Free content filtering
• End user monitoring to prevent misuse
• Specialized endpoints to scope API usage
• The API supports review of applications before they go live
• continual improvement of safety tools

The vendor states API has been deployed in thousands of applications with tasks ranging from helping people learn new languages to solving complex classification problems.

OpenAI offers access to multiple models, each with different capabilities and price points. Ada is the fastest model, while Davinci is the most powerful. Prices are per 1,000 tokens. OpenAI says the user can think of tokens as pieces of words, where 1,000 tokens is about 750 words. Pricing is pay-as-you-go, and anyone can start experimenting with $18 in free credit that can be used during the first 3 months.
