Azure OpenAI launches GPT-4.1 with 1M context, gpt-4o audio models, and Responses API with computer-use-preview

AI Impact Summary

Azure OpenAI introduces GPT-4.1 and GPT-4.1-nano, with GPT-4.1 offering a 1M token context for long-context workloads. New gpt-4o audio models (gpt-4o-transcribe, gpt-4o-mini-transcribe) and gpt-4o-mini-tts expand real-time transcription and text-to-speech via the /audio and /realtime APIs, enabling voice-enabled workflows. The Responses API combines chat and assistants capabilities and adds the computer-use-preview model, which is access-controlled; provisioned spillover and a per-call content-filter header provide traffic management and runtime policy controls that teams should plan to adopt in deployment templates.
