GPT-6.1 Sol (Fully Tested) + Dots & All DevDay Launches Explained: IT BEATS OPUS 5.5!?

From the creator

In this video, I’ll be testing OpenAI’s new GPT-6.1 Sol model across all eight KingBench 3 tasks in Codex. I’ll also cover the major DevDay announcements, including Dots, Ultrafast, reusable Codex Cloud environments, browser-capable agents, ChatGPT Space, Pages, plugins, and more. -- Key Takeaways: 🚀 GPT-6.1 Sol is designed for complex coding, computer use, and professional workflows at a lower cost than GPT-6 Astra. 🧪 The model is tested on eight KingBench 3 tasks, including 3D objects, an elevator simulation, an archery game, and local model fine-tuning. 🏆 GPT-6.1 Sol scores 78 out of 80, achieving an overall KingBench 3 score of 97.5 percent. 💻 The contact lens case, archery game, panda SVG, and 3D wristwatch all receive perfect scores. 🛠️ The folding table loses points for intersecting geometry, while the elevator simulation has a minor dispatching issue. 🐼 Sol successfully creates a panda dataset, fine-tunes Gemma 2B locally with LoRA, and builds a working local web application. ⌚ The wristwatch accurately handles fractional-hour time zones, date changes, customization, and smooth hand movement. 🤖 OpenAI’s DevDay announcements include Dots, Ultrafast models, reusable Codex environments, agent APIs, ChatGPT Space, Pages, and collaborative tools. 👍 Overall, GPT-6.1 Sol delivers polished and functional coding projects, making it a strong option for interactive prototypes and development work. -- Timestamps: 00:00 Intro: GPT-6.1 Sol 00:38 API pricing & specs 01:26 DevDay roundup 01:41 Dots 02:38 Ultrafast & Pro 500 03:23 Codex Cloud, CLI & Code Review 04:21 Codex Security Cloud 04:48 Agents API, Bedrock & Decisions API 05:51 Private Intelligence 06:16 Plugins, Sites & MCP Events 07:54 Space, Pages & slides 08:39 Teams, Slack & Meetings 09:29 Sign in with ChatGPT & Marketplace 10:32 KingBench setup 11:27 Elevator simulation 12:25 Contact lens case 13:21 Folding table 14:17 Panda SVG 14:53 Archery game 15:45 Counting problem 16:48 Local fine-tuning 18:18 3D wristwatch 18:41 Final scores 19:15 Verdict

AI Maker Residence at KOKO

The third AI workshop taught by our legendary teacher, Nick Sarafa. In one of the last events we did an asset manager raised an additional £25M on their fund within a space of 9 months. This is a full-day hands-on training workshop for purposeful co-creation with AI using Claude Code. Imagine having access to hundreds of billions of dollars of computing power and knowing exactly how to make it work for you through the power of super intelligence. One person did.
