This highlights a great use case for building small, sharp tools: bypassing official app delays to immediately experiment with bleeding-edge AI capabilities on your own terms.</p> <h2 id="posts">Posts<a class="anchor" href="#posts">#</a></h2> <p><strong>OpenAI WebRTC Audio Session, now with document context</strong> · <a href="https://simonwillison.net/2026/Jun/12/openai-webrtc/#atom-everything">Source</a> Simon revisited and upgraded a browser-based tool he originally built in December 2024 for interacting with OpenAI&rsquo;s realtime audio API. Users can now select GPT-Realtime-2—a model promoted as having &ldquo;GPT-5-class reasoning&rdquo;—because it still hasn&rsquo;t rolled out to the official ChatGPT iPhone app. Most practically, he added a feature to paste large chunks of document context directly into the tool, enabling interactive audio conversations grounded in specific reference material.</p>
