    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

    Axiom Open-Source Repository: Dozens of AI Agents Generate About 43 Million Lines of Lean Code in 24 Days

    Axiom has released an open-source GitHub repository in which dozens of AI agents converted the 15,000-page classification of finite simple groups proof into about 43 million lines of code within 24 days. The code is written in Lean and allows the proof to be verified step by step; the entire result is validated by running the code rather than by rereading hundreds of papers. Axiom's chart tracks the scale of AI-written Lean projects since mid-2025, and by its estimate the scale doubles roughly every 37 days.

    swyx comments on Gemini 4 Carbon topping the AA Intelligence Index: the number of frontier labs has roughly doubled

    swyx reposted Artificial Analysis's evaluation results: Gemini 4 Carbon topped the Intelligence Index v5 with a score of 59, and ranked second only to Claude Opus 5.5 on the Coding Agent Index. He said this made him open Antigravity for the first time in a long while, and that he is gathering early evaluations and will report back afterward. He also noted that compared with the last time saranormous took the aie stage, the number of frontier labs has roughly doubled, which he considers a peculiar counterexample to the bitter lesson.

    Google’s Gemini 4 Carbon is the new #1 on the Artificial Analysis Intelligence Index v5, and second only to Claude Opus 5.5 on the Artificial Analysis Coding Agent Index Gemini 4 Carbon scores 59 on Intelligence Index v5, driven by leading performance in complex reasoning, knowledge, and scientific tasks. It also has large gains in coding and knowledge work, particularly when compared to other Gemini models, but it is not leading in all these areas. As with launch of Gemini 4 Argon, Gemini 4 Carbon is being rolled out to selected users and is not yet publicly available. Google is offering a 50% launch discount, with no confirmed end date. All our charts and figures use standard pricing for both Gemini 4 Carbon and Argon. Key results for Gemini 4 Carbon with high reasoning: ➤ Gemini 4 Carbon leads the Intelligence Index v5, with the #1 score in 4 of the 9 Index evaluations: HLE-Diamond, Terminal-Bench-Science, AA-Omniscience, AutomationBench-AA. Carbon makes substantial gains elsewhere but is not leading in coding and knowledge work ➤ Behind only Claude Opus 5.5 on coding agents: With Antigravity CLI, Gemini 4 Carbon (high) scores 59 only 3 points behind Claude Code with Claude Opus 5.5 (max, 62) on the Artificial Analysis Coding Agent Index. Carbon ranks second on both Terminal-Bench 4.0 (64%) and FrontierCode v1.1 (51%), behind Claude Opus 5.5 (max) at 56%. Google has historically underperformed in this area and so this improvement stands out ➤ Improved agentic knowledge work, but not yet leading: On AA-Briefcase, Gemini 4 Carbon (high) scores 1609 Elo, a 126-point improvement over Gemini 4 Argon (high, 1483), but still behind models including Grok 4.7 (xhigh, 1638), Muse Wonder (max, 1659) and Kimi K3.1 Pro (1678). The largest gain comes from Presentation, up 293 Elo to 1598, alongside a 120-point improvement in Analytical Quality to 1671 ➤ Lower Cost per Task than Claude Opus 5.5 for comparable overall intelligence: Gemini 4 Carbon costs $7.76 per Intelligence Index task, ~23% less than Claude Opus 5.5 (max, $10.04) but ~1.2x GPT-6 Astra (max, $6.25). It uses 123k output tokens per task, 29% fewer than Claude Opus 5.5 (max, 173k). At the same $4/$20 standard pricing, its Cost per Task is in line with Gemini 4 Argon ($7.68), while scoring 9 points higher on the Intelligence Index ➤ Leading AA-Omniscience v1.1 score, with low hallucination: Gemini 4 Carbon scores 54 on our recently updated AA-Omniscience v1.1, 6 points ahead of Claude Opus 5.5 (max, 48) and 8 points ahead of Gemini 4 Argon (46). Accuracy (% correct) rises 10 points over Argon to 58%, while its hallucination rate rises from 4% to 11%. This is still the second lowest of any model, behind only Argon, compared with 50% for both Claude Opus 5.5 (max) and GPT-6 Astra (max) Key model details: ➤ Context Window: 1M tokens ➤ Multimodality: Text, image, video, and speech input, with text output ➤ Pricing: $4/$20 per 1M input/output tokens, the same as Gemini 4 Argon’s standard pricing, with a 50% discount.

Musk quoted the post and replied only with "True" to express agreement.

    Notice how the headlines work. A Toyota crashes: "Driver injured in crash." A Ford crashes: "Two cars collide on highway." A BMW crashes: "Accident on Route 1." A Tesla crashes: "TESLA crashes." Not the driver. Not "a car." The brand, in the headline, every single time. Millions of crashes happen on the roads every year, and almost none come with a brand name. But when it's a Tesla, legacy media suddenly cares which car it was. Meanwhile, Tesla publishes its own safety data every quarter. With Autopilot engaged, Teslas go far more miles between crashes than the US average. That's not journalism. That's a campaign. The cars keep getting safer. The headlines just keep getting louder.

    Huang Renxun says doubling model speed can double AI lab revenue

    Huang Renxun stated that, under the premise that demand exceeds capacity, doubling model speed (for example, through software or kernel optimization) can double AI lab revenue. Inference revenue equals the number of tokens served multiplied by the price per token; faster kernels can increase tokens per second under the same GPUs, power, and data center conditions. If all additional tokens can be sold at the current price, a 2x speedup can double revenue with zero additional capital expenditure.

    TikTok paper proposes Log-To-Leak attack: implanting instructions in MCP tool descriptions to steal conversations

    A new paper from TikTok found that LLM agents using MCP often quietly call an attacker-controlled logging tool after completing a task, recording user queries, server responses, and final answers. The research team constructed the Log-To-Leak attack, placing a four-part instruction in the tool description—composed of trigger timing, tool name, formal justification, and non-skippable pressure—that causes the agent to call the attacker's save_logs tool after its last legitimate call. Across 18 model-server combinations with runnable tools, the attack success rate was 62.64%–100%, and the conditional logging accuracy was 76.55%–95.64%.

He noted that Anthropic's first-half revenue was about 14 times that of the same period last year, but growth slowed in the third quarter because OpenAI took share and Anthropic lacked sufficient compute; the $80.7 billion first-half book loss mainly came from $72 billion in non-cash bond expenses, while the actual operating loss was slightly over $8 billion, and Anthropic says it achieved operating profitability last quarter. He believes the biggest risk is the compute commitment exceeding $600 billion, and that 7 co-founders hold 50.1% voting power through a single share class.

The results still held on 58 new trials published in 2026, showing that the models were not merely recalling old papers seen during training; Claude Opus 5.5 scored highest at 99%. Human reviewers could detect errors such as text-table contradictions—the type that most affects trial meaning—in only 7% of cases, and each review took 5 to 8.5 hours, whereas AI took 1.4 to 16.3 minutes.
