According to initial reports on social media, the recently released Claude 3 Opus is capable of generating coherent code for entire applications. Developer Murat Ayfer shows an impressive demo: He lets Claude 3 generate a multi-user drawing application in the browser with a single prompt on the first try. Ayfer used the following prompt: "Make a multiplayer drawing app where the strokes appear on everyone else's screens in realtime. let user pick a name and color. save users to db on login." If you want to test the app, you can find the code here.

Anthropic's Claude 3 beats OpenAI's GPT-4. Right? In the benchmarks published by the company, the largest model, Opus, beats GPT-4, but a closer look reveals that it is complicated: Anthropic tested its latest model against the first version of GPT-4, not newer versions like GPT-4 Turbo. The reason: OpenAI has so far only published benchmarks for the old GPT-4 model, which can only be accessed via the API. However, there are GPT-4 Turbo results for some benchmarks that do not come directly from OpenAI. AI researcher Lawrence Chan has compiled them. A look at these numbers makes it clear: In every benchmark where Claude 3 and GPT-4 Turbo were compared, the OpenAI model still beats the best model from Anthropic - even if only by a few percentage points. However, the models are so close that the question of which model is better depends very much on the task at hand - and is mostly a matter of taste.

ChatGPT can now read messages out loud. Simply touch and hold a message in the iOS or Android app and select the "Read Aloud" option. The web version has its own read-aloud button below the message. The synthetic voice in the demo doesn't sound quite as convincing as ElvenLabs and the like - probably for cost reasons. We had hoped that OpenAI would respond with GPT-4.5 or GPT-5 to Claude 3 just announced by Anthropic, which is supposed to surpass GPT-4. But reading messages out loud is fine, too.
