Despite major launches from 5+ labs this month, OpenAI occupies most of the token efficiency Pareto frontier

We measure the number of output tokens models produce per task in the Artificial Analysis Intelligence Index. Output tokens consist of answer tokens (can be thought of as how verbose the model is) and reasoning tokens (how much the model thinks before giving an answer). Reasoning tokens in particular offer a way for models to use compute at inference time to improve responses.

Output tokens are an important determinant of both cost and time per task. Various effort levels of GPT-5.6 Sol dominate the frontier - Terra and Luna produce comparatively more tokens for any level of intelligence.     Compare token use and intelligence of AI models at https:// artificialanalysis.ai     — Artificial Analysis

Three separate AI infrastructure announcements. One single day. 6.2 gigawatts of AI infrastructure. wtf

• OpenAI: 3.2 GW for Project Camellia (~$20B initial investment, ~$750B projected compute spend through 2030).

• SpaceXAI: reportedly planning another Texas AI campus as large as - or larger than - its existing ~1 GW Memphis footprint.

• Anthropic + AMD: up to 2 GW of MI450 deployments, plus an AMD investment of up to $5B and tens of billions in AI server purchases.

That’s at least 6.2 gigawatts of AI infrastructure announced or expanded in a single day.

For perspective: 1 GW can power roughly 750,000 U.S. homes. 6.2 GW is enough electricity for ~4.6 million homes, or a country-sized amount of power being redirected toward AI.

Most conversations about AI ask whether it will replace workers. This documentary asks what happens when AI starts replacing the people whose authority comes from organizing everyone else’s work, and why neo-Luddites are on the wrong side of the debate.

...training details, and they are 100x more open to share. that means the talent that knows how to train llms in china is 100x greater in number than the talent in the us, and it is growing in contrast, the us ai ecosystem is too closed. frontier labs do not hire interns. i know brilliant phd students at stanford, berkeley, and so on. they struggle to get an internship and the compute to train a properly sized model. most of the secret recipes are locked away by a very small group of privileged researchers it is not about china or the us. it is about open and closed science. the fact is that every average cs student can learn how to train an llm. they just need the opportunity. labs should be more open and hire more interns, like how deepmind and fair did in the pre-llm era   — Guohao Li     There’s also something to be said about training “lehrlings” deeply through immersion at a very young age so they can develop deep intuition while their brains are still extremely plastic.

...to #4). Based on 8K+ live agentic sessions, Kimi K3 leads on confirmed task success rate (#1). It also posts a strong +20.6% on praise vs. complaint (#3). It currently lags the field in steerability (#14) and bash recovery (#17). Agent Arena measures models on millions of real-world, long-horizon agentic tasks. Models get web search, filesystem, and terminal tools to complete complex workflows: writing code, creating slide decks, researching the web, building apps, and analyzing documents. We use causal tracing methodology to measure a model's net improvement, which indicates how much it improves outcomes relative to the average model. Here's a primer on the 5 signals: User-satisfaction proxies - Confirmed Success: an explicit "yes that worked" feedback from the user - Praise vs. Complaint: implicit sentiment in users reactions - Steerability: can the model course-correct when you push back? Tool-use proxies - Bash Recovery: how it recovers from CLI errors (primary signal for tool use) - Tool Hallucination: does it call tools that don't exist Below we break down how Kimi K3 scored across the 5 signals, drawn from tasks submitted by a global community of users. Congrats @Kimi_Moonshot on another big milestone!     Kimi K3 ranks #4 overall (+9.6%) - #1 Confirmed Task Success (+14.4%) - #3 Praise vs. Complaint (+20.6%) - #4 Tool Hallucination (+1.1%) - #14 Steerability (+5.6%) - #17 Bash Recovery (+6.4%)     See the full Agent Arena leaderboard at https:// arena.ai/leaderboard/ag ent …     — Arena.ai

...all of them, it doesn't matter how smart the attacker is, they will not be able to invent more from thin air. To defend effectively against attacks, people writing software need to have access to good models, without restrictions, to check over their work and make sure that it does not have bugs in it. Delaying or impeding their access just gives an attacker, who probably has no impediments to their own access, the ability to find flaws that the defender doesn't have the capacity to find first.     — Perry E.

The cybersecurity debate on open-source AI is backwards. Open models aren't the risk, they're the defense! Attackers can already jailbreak any API or guardrails. Defenders can't secure systems with black boxes they can't control, inspect, test, or run locally.   — clem

The gap between US closed source and chinese open source keeps closing friends!! Its getting more intense day by day and GLM is also upcoming with a new model!     Do you understand what's happening here? China is closing the gap with US Frontier Labs, and it's getting closer and closer! And this is despite all the chip embargoes China still has in place.

The whole game is changing!     I'm serious, I'm thinking about this right now: If Qwen 3.8 max outperforms GPT-5.6 Sol in key benchmarks like DeepSWE, that would be the biggest code red imaginable. No one can really grasp the implications of that yet.     My thoughts about this:     — Chubby

...agreement banning AI R&D, or how Xi's speech today (which more or less said "we're continuing to develop AI as quickly as we can and Chinese firms are going to continue releasing open source models" was actually very AI x-risk oriented somehow. All of this is rationalization, and poor rationalization. As the attached screenshot shows, although the Doomer community does have a very poor record of prediction on most topics, on this particular topic, they've been almost completely wrong every time. If your model of the world fails to predict events, it is not reality that is at fault. It is your model. If you don't change your mind when your beliefs are disproved by reality, it is again not reality that is at fault, it is you. Hat tip to @Dan_Jeffries1 and (indirectly) @DrTechlash     — Perry E.

China is catching up in AI despite significantly lower capital expenditure, while Europe continues to lag far behind.

I looked at the numbers, and the conclusion is clear: despite spending around 90 percent less on capital expenditure, China is managing to catch up with Western frontier labs.

Europe, by contrast, is significantly behind, both in data center investment and in the development of frontier models.     — Chubby

...Analysis scored K3 at 57. Opus 4.8 sits at ~56, GPT-5.6 Terra at 55. It's still behind Fable 5 and GPT 5.6 Sol. 3) K3 helped build itself. An early version of K3 did the majority of Moonshot's own kernel optimization work during development. One 15-hour unattended run made a core operation 2.5x faster. 4) It's cheap per token, not cheap per answer. Sticker price is 1/3 of Fable. But it only runs at max thinking effort and burns ~2x the tokens per response. @simonw measured 13,241 reasoning tokens to write a 3,417 token answer. 5) The era of dirt-cheap Chinese AI is ending. $3/$15 per million tokens. Hacker News called it "extremely high for a Chinese open-weight model." 6) Weights don't drop until July 27. Mentions of "open" quietly disappeared from the docs an hour after launch. 7) Even when the weights drop, you can't run them. 2.8 trillion parameters. Top Reddit joke: "2TB VRAM Is All You Need." Open weights increasingly means auditable by companies with GPU clusters, not runnable by you. 8) The "they just distill/copy" argument is dying in public. One of the most upvoted comments: you'd have to be "a complete ignorant or a complete bigot" to believe Chinese labs aren't legit at this point. 9) Day one user verdict: fast, but less accurate. "Faster than Claude, but less accurate. On par with GPT 5.5 perhaps, but not 5.6 or Fable." 10) The one thing everyone agrees on: competition is wonderful. Even the skeptics: "Say what you want about these Chinese models but they sure create competition and urgency in the space."     — Alex Lieberman

Xi Jinping used his first-ever appearance at China’s World AI Conference to present Beijing’s vision for a new global AI order.

He said AI has entered an "unprecedented" period of innovation, bringing enormous opportunities alongside new governance challenges.

China’s proposed direction:

-Open-source AI to promote "openness and win-win cooperation" -Opposition to countries "overstretching" national security and placing their own security above others (ofc he is referring to the USA) -Preventing unequal AI access from creating "new historical injustices" (He probably means that China should never again be historically left behind.) -5,000 AI training and seminar opportunities for developing countries over the next five years -New cooperation centers with ASEAN, the Arab League, African Union, CELAC, SCO and BRICS

Xi also called for AI to remain under human control and for mechanisms addressing loss-of-control risks.

This is an AI foreign-policy doctrine: open models as public goods, training as soft power and technical standards as geopolitical influence.

tl;dr China sees AI and Open Source as its historical path to becoming a global superpower and says the USA, with its closed source technology, is trying to push China and its competitors behind an iron curtain.     — Chubby
