GPT-5.5 (xHigh) ranks #2 on Agent Arena ( 10.6% net improvement), making it the highest-ranked OpenAI model closely behind Claude Fable 5 (High). Per signal breakdown, GPT-5.5 (xHigh) ranks #1 in Praise vs. Complaint ( 29.4%) and Bash Recovery ( 14.1%), scoring higher than Claude Fable 5 (High) on both signals. It trails Claude Fable 5 (High) on Confirmed Success ( 5.4% vs. 17.6%) and Steerability ( 1.9% vs. 5.4%). Agent Arena evaluates models on millions of real-world, long-horizon agentic tasks. Models use tools like web search, filesystem, and terminal to complete complex workflows: writing code, creating slide decks, researching the web, building apps, and analyzing documents. We use causal tracing to measure model performance across real-world agentic tasks. More breakdown of GPT-5.5 (xHigh) across five signals in the thread.
Introducing Agent Mode: Agentic AI is now measured in the Arena. Agent Mode can do deep research, create reports, generate images, build websites, debug code, and more. It completes more complex tasks by using tools like web search, bash in a sandbox environment, image generation, file writing, and asking follow-up questions. Frontier models are waiting for you in Agent Mode to take on real-world tasks. GPT-5.5, Claude Opus 4.7, Gemini 3.1 Pro, and top open models. Test them yourself.

Here's a simple loop: Tell codex to maintain your repos, wake up every 5 minutes and direct work to threads. That makes it easy to parallelize steer work as needed. I use a orchestrator skill combined with my triage autoreview computer use skills, so some work can land autonomously. github.com/steipete/agent-sc… github.com/steipete/agent-sc…

A well-peered network is essentially a superpower in our industry. I spent the day at Cloudflare Immerse in Munich and it was highly impressive to see how German enterprises are building their AI and security stacks directly on top of Cloudflare’s massive connectivity. I am incredibly proud that DE-CIX plays a direct role in keeping them one of the best-connected networks globally. Strong partners make for strong infrastructure. Speaking of building strong infrastructure... if your team prefers writing code over clicking through portals, DE-CIX offers Terraform providers for our interconnection services. If you are running Infrastructure as Code, let us talk 🤝

25 Jahre SwissIX. Wer sich so lange und erfolgreich in unserer Branche behauptet, ist unbestreitbar das Rückgrat des Schweizer Internets! Gratulation! 💪🍾 Es ist uns eine große Freude, dass DE-CIX seit drei Jahren als technischer Partner für den Plattformbetrieb unseren Teil zu dieser Erfolgsgeschichte beitragen kann. Wir haben das gestrige Jubiläum genutzt, um gemeinsam die Köpfe zusammenzustecken und die strategischen Themen der Zukunft anzusprechen. Schließlich wollen wir sicherstellen, dass die Latenzzeiten auch in den kommenden 25 Jahren nicht länger werden als die Warteschlangen am Skilift 😉

Einmal im Jahr wagen wir uns aus den klimatisierten Serverräumen ans Tageslicht. Der eco Datacenter Expert Summit steht wieder an. Es ist immer wieder spannend zu beobachten, was passiert, wenn Infrastruktur-Betreiber, Wissenschaftler und Politiker in einem Raum zusammenkommen. Spoiler: Die Latenz bei Diskussionen ist erfreulich gering und der Austausch tatsächlich konstruktiv. Das absolute Highlight ist natürlich die abendliche Award-Verleihung für die besten Innovationen der Branche. Ein starker Beweis dafür, dass unsere europäische Datacenter-Industrie massiv vorantreibt, was die Digitalisierung am Laufen hält 🚀 Ein absoluter Pflichttermin für starke Netzwerke und klare Worte.

Your Google Cloud AI is only as smart as the data it can reach. 🧠☁️ Having a great time today at the Google Cloud Summit in Frankfurt! AI is dominating the conversation, and for good reason: it's making developers 40% faster with 20% better quality. But AI doesn't work independently. It requires seamless access to massive, distributed data sources to function. Connecting those dots is what we do best. @DE-CIX provides the critical cloud connectivity and Cloud ROUTER infrastructure to make it happen. We currently connect to Google Cloud via 37 global on-ramps with a total of 730 GE capacity. It is incredible to see how strongly enterprises rely on Google Cloud, and we are proud to provide the ultra-fast lanes to get them there. Let's connect if you are here at the Summit! 👇

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors. Available today at the same price.
