GPT-Realtime-Whisper is OpenAI’s streaming speech-to-text model for low-latency live transcription. It transcribes speech as people talk, enabling captions, meeting notes, voice-agent understanding, classroom or broadcast transcription, and faster spoken-workflow automation while the conversation is still happening.NewMultimodalReleased 1mo ago
-
GPT-Realtime-Translate is OpenAI’s live speech translation model for multilingual voice experiences. It translates speech from more than 70 input languages into 13 output languages while keeping pace with the speaker, making it useful for support, education, events, media, creator platforms, and cross-border conversations.NewMultimodalReleased 1mo ago
-
GPT-5.5-Cyber is OpenAI’s specialized cybersecurity variant of GPT-5.5 for verified defenders handling high-risk authorized workflows. It is designed for more permissive behavior in controlled cyber tasks such as red teaming, penetration testing, exploit validation, and critical-infrastructure defense, with stronger verification and account-level controls.NewMultimodalReleased 1mo ago
-
GPT-Realtime-2 is OpenAI’s live voice model with GPT-5-class reasoning, built for voice agents that can listen, reason, use tools, recover from interruptions, and respond naturally in real time. It supports longer 128K context sessions, controllable tone, stronger domain vocabulary, parallel tool calls, and adjustable reasoning effort.NewMultimodalReleased 1mo ago
-
GPT-5.5 Instant is OpenAI’s updated default ChatGPT model for fast everyday use. It is built for clearer, more concise, and more personalized responses, with better factual accuracy, stronger image understanding, improved STEM performance, and better judgment about when to use web searchNewMultimodalReleased 1mo ago
-
GPT-5.5 is OpenAI’s newest flagship model for real work on a computer. It is built for stronger agentic coding, computer use, knowledge work, and early scientific research, while matching GPT-5.4’s per-token latency in real-world serving and using fewer tokens to complete the same Codex tasks.NewMultimodalReleased 2mo ago
-
Privacy Filter is OpenAI’s bidirectional token-classification model for detecting and masking personally identifiable information in text. It is built for high-throughput data sanitization workflows, can run on-premises, supports a 128,000-token context window, and is designed to label text in a single forward pass rather than token-by-token generation.NewTextReleased 2mo ago
-
ChatGPT Images 2.0 is OpenAI’s upgraded image generation and editing system in ChatGPT, powered by a new flagship image model. It is designed for faster, more precise image creation and photo editing, with stronger detail consistency, better intent matching, and support for preset styles and creative exploration directly inside ChatGPT.NewMultimodalReleased 2mo ago
-
GPT-Rosalind is OpenAI’s frontier reasoning model for life sciences research. It is purpose-built for biology, drug discovery, and translational medicine, with stronger tool use and deeper understanding across chemistry, protein engineering, and genomics to support scientific workflows such as hypothesis generation, evidence synthesis, and experimental planning.NewTextReleased 2mo ago
-
Trusted Access for Cyber is OpenAI’s trust-based access framework for legitimate defensive cybersecurity work. It is designed to expand access to OpenAI’s most cyber-capable models for verified defenders and enterprises, while keeping safeguards against misuse such as policy enforcement, malicious-request refusals, and automated monitoring for suspicious activity.NewTextReleased 2mo ago
