Fable 5.5 Grand Entry, GPT-6.1 Sol Big Enhancement | AI News
Fable 5.5 has been leaked and the results are very impressive, with a lot of people saying that they are much better than Opus 5.5. GPT-6.1 Sol has also got an enhancement on the speed issue, while Gemini 4 Argon initial results are now coming out, and Deepseek harness is now available in desktop. First I explain what the Fable 5.5 leak really is, and why some Claude users are already routed to it while the model picker still shows Fable 5.1. We also describe how to check if you are accessing the new model, using the famous Tibo check. After that, we go through the first Fable 5.5 results, from 40,000 years of art history in 15 seconds to a short film built entirely in code, and a direct comparison with Opus 5.5. Next, we discuss how OpenAI fixed the slow start of GPT-6.1 Sol, and how the global usage reset seems to compensate for this issue. Then we look at the initial results of Gemini 4 Argon, and why they are not quite what the benchmarks suggested. We also cover the DeepSeek Harness desktop release and Claude Code mods. Finally, I describe various caveats, as I share my honest take on what is confirmed and what is still a rumor. This is again an important milestone in my quest to find the best AI model in 2026.
