Azure OpenAI Service - Pricing | Microsoft Azure
If your assistant calls Code Interpreter simultaneously in two different threads, this would create two Code Interpreter sessions (2 * $-). Each session is active by default for one hour, which means that the price is for up to one hour of giving instructions to Code Interpreter in the same thread. Featured in the Realtime API, the GPT-4o-Realtime-Preview supports multilingual speech-to-speech capabilities.
GPT-4.5 has an API price of $75/1M input and $150/1M output. ChatGPT Plus users are going to get 5 queries per month with this level of pricing.

May 13, 2024Realtime API Costs Since Update?
I feel it got generally cheaper, especially with the addition of the gpt4o-mini models, and the alignment to 1M token in/out. I agree it's not straightforward to compare apple to apple but that's my general feeling. We've been playing with AI voice models since day one - OpenAI of course, but also Gemini and Ultravox.ai - and find them incredible to create realistic, voice-based UX! In our experience, the tricky and costly part is really to refine the initial system instructions, and subsequent prompts to reach human-like interactions. We're building Fine Voicing ( finevoicing.com ), a simple tool to help refine our prompts and interactions with those models. It generates realistic conversations, all orchestrated by AI agents (namely one acting as another speaker, and one moderating it). Now that the OpenAI Realtime API supports more models and got cheaper, we're launching it more publicly. I'd love to hearing your feedback about it and if you see this being useful!
