Announcing Artificial Analysis Intelligence Index v5, featuring 2 new benchmarks and 3 upgrades. For the first time, the majority of the Index is built on private datasets The Artificial Analysis Intelligence Index is our composite measure of model capabilities across tasks reflecting real-world usage today. v5 is our biggest upgrade since v4 launched in January. With v5, 60% of the Index is now based on evaluations with private test sets or held-out answers. Alongside Intelligence Index v5, we’re launching the Artificial Analysis Progress Index v1, which tracks model capability over time on one continuous scale. New to the Intelligence Index: ➤ FrontierCode 2.0: Cognition's newly-launched private benchmark of real-world coding tasks, graded on whether a repository maintainer would merge the agent's change ➤ Terminal-Bench-Science: 70 agentic scientific research tasks, run in a terminal environment Upgraded: ➤ HLE-Diamond (replacing Humanity's Last Exam): a refined 1,000-question version of Humanity's Last Exam, split evenly between reasoning and knowledge questions ➤ AA-Omniscience v1.1: An updated dataset with saturated and public set questions removed, new questions added, and ambiguous or erroneous questions revised ➤ CritPt v2: a private, 40-question hard subset of CritPt v2, revised by the CritPt authors and run with a code-execution tool Staying in the Index: AA-Briefcase, AutomationBench-AA, GDP.pdf and Terminal-Bench 4.0 Removed from the Index: GDPval-AA v2.1, SciCode, and AA-LCR v1.1 Key results: ➤ Claude Opus 5.5 (max) leads at 58, ahead of GPT-6 Astra (max, 57) and GPT-6.1 Sol (max, 55): Anthropic and OpenAI hold the top five models. Gemini 4 Argon (high) is next at 50 ➤ The open weights gap widens from 3 points to 12: Kimi K3.1 Pro (weights not yet released) is the top open weights model at 46. Among released weights, DeepSeek V4.1 Flash 1017 (max) and GLM-5.3 (max) lead at 32 - 26 points behind the leader and below Claude Haiku 5.5 (max, 36) ➤ Cost per task varies by more than 13x among the leading models: of the 10 highest-scoring models shown, GPT-6.1 Terra (max) is the cheapest at $0.96 per Intelligence Index task and Claude Fable 5.1 (max) the most expensive at $13.04

i've gotten a lot of questions about how i manage my X account with grok bot, so i'm sharing my bot tibot today! he watches your mentions and: • finds every post about you or any keywords, tagged or not • gives one short, sorted digest a day (or hourly, your call) • skips spam and noise • translates non-English posts • can auto block trolls and abuse • never posts for you i still write all my posts and articles by hand but tibot has been very helpful with keeping me in the loop. hire tibot today! x.ai/bot/xZ4wRvomWqzCXnyYFr7…

A home miner just mined a Bitcoin block using a compact FutureBit Apollo Machine! Absolutely insane! Let's remember this moment solo.ondream.ai/

Gradually, then suddenly. We (the people) hit a Bitcoin block today. ⛏️ Bitcoin belongs in the hands of sovereign individuals. And we’re building to keep it there.

Day 22/ Terra is back! Our first model that is significantly better at writing, personality and nuanced understanding of requests. Packs a punch across the board, very good at computer use, and gives 2X more usage than 6.1 Sol across API and subscriptions.

Anthropic has filed an S-1 registration statement with the SEC related to its proposed IPO.

Day 21/ Wonder what happens the remaining seven days. But today is a reset.

なんでレインコートはこう作らないんだろう？

Correct. Using Starlink, a civilian commercial service, for offensive drone strikes to kill people has never been allowed, nor should it be. Starshield, a different system, is controlled by the US government. What they decide to do is up to them. Ukraine military violated Starlink terms of service and used it for offensive drone strikes to kill people. That loophole was closed last week. Starlink remains critical to the defense of Ukraine, as it is the only system that cannot be jammed or blown up, at least for now. Were Starlink to be turned off, the Ukrainian front line would collapse immediately. This is NOT a threat, it is simply a statement of fact. Starlink was also crucial to preventing Russia from overrunning Ukraine in the early days of the war, as all other means of communication were destroyed or jammed by Russia. SpaceX has done more to defend Ukraine than any private company on Earth BY FAR. That said, I have nothing but UTTER CONTEMPT for the virtue-signaling evil warmongers who push for endless slaughter and offer no realistic solution to the conflict. May you burn in hell. End of story.

Landing tomorrow before 10am PST together with a small ship.

Day 17/ Bet you thought we forgot, but no, it’s reset day today. Also good time to remind you to get Daybreak Blue access, it only takes 15 mins and you don’t want to have to do it in the middle of an incident.

Some stats on #php2shell. In the 10 hours before it was publicly announced, across the @Cloudflare network we saw thousands of attempts to exploit it. That jumped to tens of thousands in the 45 minutes post announcement, hundreds of thousands within 2 hours, and millions now.
