Check out the quantum computer I built at Google Connect I/O 😅 The realtime AI judge was amazing, processing3 camera feeds simultaneously #GoogleIOConnect #BuildwithGemini

Today I conducted a real-world comparison of 3 AI coding agents: 1️⃣ Mistral Vibe CLI (devstral-2) 🇫🇷 2️⃣ OpenAI Codex (GPT-5.3-Codex-xhigh) 🇺🇸 3️⃣ Claude Code (Opus 4.6) 🇺🇸 I tasked them with a fix requiring audio API knowledge and out-of-the-box thinking. Can you guess which one succeeded? 🧵

3️⃣ Claude Code got on the right track after 7 attempts and had the epiphany 💡 after 11 attempts. My usage limit expired significantly faster than with Codex.

➡️ Codex emerged as the clear winner. Claude Code has performed well in resolving complex bugs previously, but it lagged behind Codex in this test. Mistral Vibe often generates compiler errors, suitable for routine tasks but lacks depth. As a “Go European” advocate, I hope to see improvement 🇪🇺🧠

1️⃣ Mistral Vibe got on the right track right away but then regressed 📉. After 10 attempts it produced countless compiler errors. Its response:
 “The file is in a severely corrupted state. At this point, the best approach is to revert.” 😂 So I did, but gave up after 16 prompts in total.

2️⃣ Codex got on the right track after 4 attempts. The 6th one was its epiphany that fixed it:
 💡 The audio engine was already fixed, but audio input permission was never requested (via Info.plist)

➡️ The prompt: “Fix audio recording on macOS, which results in an empty file. The log output is: …” ℹ️ The project: A large C++ codebase that includes an audio engine. 🔄 The approach: After each change by the AI, I tested the app and provided it with the result (mostly “issue persists” and the log).

These are real images of exoplanets. Four super-Jupiters, imaged 10 times over 12 years around a star 133 lightyears away. These are real, giant worlds, out there in the dark. And we can see them.

Somewhat ridiculously, Saturn now has 128 new moons, bring its total to 274. These are mostly tiny rocks, a few miles across, that orbit the planet backwards – but they might be evidence of a recent smashup in the planet's orbit. Story by me in The New York Times www.nytimes.com/2025/03/11/s...

Enceladus might have a subsurface ocean beneath the icy crust, which makes it a prime target in the search for extraterrestrial life. Its cryovolcanism ejects plumes of water vapor, ice particles, salts, and organic compounds – what more do you need to cook up friendly microscopic aliens? 👽 🧵 3/3
