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.

Description

Twigg is an innovative tool for managing context that enhances long-term interactions with large language models by transforming traditional linear chat threads into a visually branching tree of conversation nodes, empowering users to dictate the context provided to the model. Users can easily explore different conversation paths by generating new branches from any node, and they can optimize their prompts by cutting, copying, deleting, or relocating content, which effectively boosts performance while simplifying complexity. The tool features a user-friendly dashboard that monitors token usage for each model and provides clear insights into credit consumption. By allowing control of context at the node level, Twigg minimizes unnecessary token usage and facilitates the concurrent development of ideas, all without overwhelming the primary workflow. It is compatible with leading models through a Bring Your Own Key (BYOK) system and is tailored for projects requiring extended engagement, positioning itself as the “Git for LLMs” by enabling version control, branching, and meticulous context management for conversational AI tasks. As a result, Twigg not only enhances the efficiency of interactions but also empowers users to refine their conversational strategies more effectively.
