Description

Contextwaise is an innovative API and agent SDK designed for teams developing retrieval-augmented generation (RAG) applications, AI agents, and various LLM products. It evaluates retrieved content such as passages, web pages, chat logs, and tool outputs based on the current task requirements, returning relevant context while adhering to a specified token limit before the application engages its language model. A versatile REST API allows for requests in any programming language, while TypeScript and Python SDKs facilitate agent workflows and integrate seamlessly with Vercel AI SDK, Anthropic SDK, and OpenAI SDK. The output maintains the order of submissions, providing reports that detail token adjustments, potential cost efficiencies, and explanations for omitted content. Contextwaise goes further by offering request logging, customizable budgets, and quality assurance; its agent SDKs can also reveal sections of excluded tool outputs for further elaboration. By utilizing this solution, engineering teams can effectively minimize extraneous model inputs while keeping their retrieval resources, prompts, and calls to model providers intact, thus streamlining the development process. This optimization ultimately enhances their ability to create more efficient AI-driven applications.

Description

GPT-Realtime-2.1 is an OpenAI realtime model designed for advanced voice-agent and speech-to-speech AI applications. It improves on GPT-Realtime-2 with stronger alphanumeric recognition, better silence and noise handling, and more natural interruption behavior. The model supports text, audio, and image inputs, while producing text and audio outputs for interactive realtime experiences. Developers can use GPT-Realtime-2.1 across endpoints such as Chat Completions, Responses, Realtime, realtime translation, realtime transcription sessions, and related OpenAI API workflows. The model supports function calling, configurable reasoning effort, instruction following, and reasoning token support for complex voice-agent tasks. Its 128,000-token context window and 32,000-token maximum output make it suitable for longer conversations and more detailed realtime workflows. GPT-Realtime-2.1 does not support video, structured outputs, fine-tuning, or predicted outputs according to OpenAI’s current documentation. Pricing starts at $4 per 1 million text input tokens and $24 per 1 million text output tokens, with separate pricing for audio and image tokens. By combining realtime audio interaction, reasoning, tool use, and multimodal input, GPT-Realtime-2.1 helps developers build responsive AI agents for support, sales, operations, translation, transcription, and interactive voice applications.
