What is Vision Agents?

Vision Agents is an adaptable open-source Python framework aimed at creating low-latency voice and video AI agents that can utilize any model available. This innovative framework allows developers to seamlessly incorporate large language models, speech recognition, and vision models from more than 25 different providers, making it possible to develop real-time agents for various applications such as telehealth, voice assistance, live coaching, video analysis, interactive avatars, security surveillance, sports commentary, and numerous other multimodal functions. Its architecture is specifically designed to support the development of agents that can listen, speak, see, process media, access tools, and offer instant responses, all functioning on Stream's vast global edge network, which guarantees latency below 500ms. Developers can easily begin building their first agent with just a minimal Python setup by utilizing platforms like Gemini Realtime, OpenAI, Deepgram, ElevenLabs, Stream, or other compatible providers. In addition, Vision Agents supports both real-time speech-to-speech models and customizable pipelines for speech-to-text, language processing, and text-to-speech, which enables teams to quickly launch a fully operational voice agent or maintain comprehensive control over the various components involved in speech recognition, language reasoning, and text-to-speech processes. Overall, this framework not only streamlines the development of advanced AI agents but also significantly boosts flexibility and performance across a wide range of applications, making it an essential tool for developers in the AI space. Its ability to integrate multiple functionalities into a single platform further highlights its value in modern AI development.

What is GPT-Realtime-2.1?

GPT-Realtime-2.1 is an OpenAI realtime reasoning model for developers building voice agents, conversational AI assistants, and speech-to-speech applications. The model is designed to support fast interactive experiences where users can speak naturally and receive audio or text responses. GPT-Realtime-2.1 updates GPT-Realtime-2 with improved handling of alphanumeric recognition, silence, background noise, and interruptions. It supports text, audio, and image input, with text and audio output, while video is not supported. The model includes configurable reasoning effort so developers can balance reasoning depth, latency, and token usage for different voice-agent workflows. GPT-Realtime-2.1 also supports instruction following, function calling, tool use, and reasoning tokens for more complex applications. Its 128,000-token context window and 32,000-token maximum output allow it to manage longer conversations and richer task context. OpenAI lists support across endpoints such as Chat Completions, Responses, Realtime, realtime translations, realtime transcription sessions, Assistants, Batch, and related API services. The model’s documented pricing includes $4 per 1 million text input tokens, $0.40 per 1 million cached text input tokens, and $24 per 1 million text output tokens, with separate audio and image token pricing. GPT-Realtime-2.1 is not documented as supporting streaming, structured outputs, fine-tuning, or predicted outputs. By combining realtime speech, multimodal input, reasoning, function calling, and tool use, GPT-Realtime-2.1 gives developers a foundation for building sophisticated AI voice agents and interactive customer-facing applications.
