Grok 4.5 is the top non-Anthropic model on AA-Briefcase, combining frontier agentic knowledge work capabilities with leading cost and time-efficiency Yesterday @SpaceXAI released Grok 4.5, a new frontier-level model with strengths in agentic coding and knowledge work. On AA-Briefcase, Grok 4.5 scores 1328, a +578 improvement over Grok 4.3 and the highest score of any non-Anthropic model (note that GPT-5.6 not released yet). It achieves this while sitting on the cost and time efficiency frontier, averaging $1.12 per task, 86% lower than Claude Opus 4.8 (max), and 12.4 minutes per task, around half the time of Opus 4.8 (max). AA-Briefcase is our new proprietary benchmark for agentic knowledge work, testing models on a fully private dataset of realistic tasks across thousands of complex input files. Tasks require deliverables like spreadsheets, presentations, and UI mock-ups, with performance combined into a single AA-Briefcase Elo across correctness, analytical quality, and presentation quality. Key results for Grok 4.5 with high reasoning on AA-Briefcase: ➤ Frontier agentic knowledge work capabilities: Grok 4.5 achieves an AA-Briefcase Elo of 1328, the highest score of any non-Anthropic model, behind only Claude Fable 5 (1390), Claude Sonnet 5 (max, 1390), and Claude Opus 4.8 (max, 1354). Across the three AA-Briefcase scoring axes, Grok 4.5 is strongest on objective rubric criteria and analytical quality, with comparatively weaker presentation quality. It achieves the second-highest overall rubric pass rate (40.7%), behind Claude Fable 5 (56%) and Claude Sonnet 5 (42.3%) ➤ Leading cost efficiency: Grok 4.5 averages a cost of $1.12 per AA-Briefcase task, placing it on the cost-performance Pareto frontier. This is much most cost effective than peer models such as Claude Opus 4.8 (max, $8.26) and GLM 5.2 (max, $1.71) ➤ Faster task completion: Grok 4.5 averages 12.4 minutes per AA-Briefcase task, also placing it on the speed-performance frontier. It is much faster than Claude Opus 4.8 (max, 23.9 min) and Claude Sonnet 5 (max, 36.9 min), primarily due to lower turn use. Grok 4.5 averages just 23 turns per task, ~40% of GLM 5.2 (max, 56) and ~13% of Claude Sonnet 5 (max, 183) Congratulations to @SpaceXAI, @cursor_ai, and @elonmusk on the impressive release!

These guys (@Frojax_) have been doing great work and have a YouTube/Rumble channel as well. Check out their full livestream from the event.

I watched them get silenced in real time as they were interviewing Thomas Rousseau. You are just as bad as the rest of them @elonmusk

As much as people are going to hate this, if the below "petition" or anyone else with influence can't solicit a response and action from Elon Musk, I propose deleting our subscriptions and migrating to Gab. @BasedTorba has proven time and again he does actually care about free speech and the consequences of losing it. We should not continue supporting, whether through data aggregation or monetarily, people who hate us for our views and silence us. If we truly care about our people, our rights, and our voice, we need to act like it. I have been using Twitter/X since 2011. I have made great friends on here. I have enjoyed the UI, the community, everything. However, at a certain point we must collectively agree enough is enough. This is no different than buying products from our people. They are blatantly proving we don't belong here and they don't want us here. We should go somewhere where we do belong and does want us. This is not a paid shill. Andrew Torba does not follow me, but after I lost my account yesterday I immediately made an account there, where PF does and is allowed to exist. It's high time we put our money where our mouth is and practice what we preach.
