OpenAI's 2024 DevDay unveiled several new tools for AI app developers, including a public beta of the "Realtime API" for building low-latency, speech-to-speech experiences. As reported by TechCrunch, the event also introduced vision fine-tuning, model distillation, and prompt caching features, aimed at enhancing developer capabilities and reducing costs.
Realtime API in Action
The Realtime API showcases OpenAI's commitment to enhancing conversational AI experiences. In a demonstration, OpenAI's head of developer experience, Romain Huet, presented a trip planning app that utilized the Realtime API to enable natural, low-latency conversations between users and an AI assistant

. Some key applications include:
- Autonomous vehicles: Improving lane detection and speed limit sign recognition
- Medical imaging: Enhancing diagnostic capabilities for specific conditions
- Visual search: Refining object recognition and image classification
- Mapping services: Boosting accuracy in identifying road features and landmarks

. This demonstrates the potential of vision fine-tuning to significantly enhance AI-powered services across various industries with relatively small datasets.2 sources
Catching Up on Caching
Prompt caching is emerging as a crucial feature for AI companies to reduce costs and improve performance. Anthropic introduced this capability for its Claude models, claiming cost reductions of up to 90% and latency improvements of up to 85% for long prompts

. OpenAI followed suit, offering a 50% discount on recently processed input tokens3
. The feature works by storing and reusing previously computed attention states, allowing models to retrieve them for similar prompts instead of recalculating4
. This is particularly beneficial for applications involving conversational agents, coding assistants, and large document processing, where consistent context is maintained across multiple interactions5
