Using Grok agents in background mode
Andrew Milich@milichab· 12 июл. 2026 г.@arthurkatcher 1) Yes! Use `.grok/agents` or config.toml (see below), adding to the docs site right now.
2) Yes: Agents can spawn background subagents, or try /dashboard, to move your agent to the background and create another. I've been using /dashboard as my default.

I take it all back. We just got access to eval Grok 4.5 and it has landed above GPT-5.6-Sol and just shy of Opus for browser use.
Because cache input is expensive, the overall cost is only 10% cheaper than opus. Its overall a bit faster.
We have another opus-class model in the
Alexander Yue@Alezander907· 12 июл. 2026 г.Some new model release and my eval scores:
gpt-5.6-sol is a small improvement on browser tasks, but seems to consume many more tokens
Muse spark 1.1 outperforms gemini 3.5 flash at a cheaper price, but is not overall very good
Claude sonnet 5 is 5th best performance at higher

Necessarily so, as power harnessed would be more than a trillion times what human civilization uses today.
The economy will be measured in energy and mass at that point, not dollars.

I say both energy and mass, as they are separate scarcities for practical purposes, despite being technically “equivalent”, as described by Einstein’s famous equation.
Our solar system has only a tiny percentage of non-solar atoms with which to build things.

I would like to offer a counterargument that LLMs (or maybe AIs) cannot jump.
Before AlphaGo, the AI field had the same argument for Go: there are 2.08 × 10^170 possibilities, nothing fits in the computer, and there is no way AI could possibly predict the outcome of the next
Han Xiao ✈️ ICML 2026@hxiao· 9 июл. 2026 г.interesting position paper throwing cold water on autoresearch/ai scientist: LLMs can't jump.
The thought experiment is this: Take an LLM with a 1905 knowledge cutoff. Feed it every paper, every dataset, every equation of that era. Could it invent general relativity?
No.

Elon Musk explains why the Sun is humanity's ultimate energy source:
"The vast majority of Earth's energy already comes from the Sun. Without it, Earth would be a frozen ice ball
A roughly 100-mile by 100-mile area of solar panels....about a corner of Arizona, could generate enough electricity to power the entire United States"
The challenge isn't whether enough solar energy exists
It's building the infrastructure to capture, store, and distribute it efficiently

The mega bull case for AI infrastructure would be *if* market share shifted away from certain frontier labs with 90%+ inference margins toward cheaper models, whether open-source or closed.
It would increase the ROI on AI spend for end customers by increasing intelligence per dollar, which would drive incremental token demand. Margin dollars would effectively get redistributed from the frontier labs to AI infrastructure providers. The infra winners would be those with the lowest per token cost and the winners at the model layer would be those with the highest token efficiency.
There are many reasons Jensen is so focused on open source, but this is likely the most important one as I think he is probably less worried about a monopsony these days. Lower margin % at the model layer = more margin $ at the infra layer all else equal.
With SpaceX and Meta being vertically integrated and possessing the #3 and #4 models respectively it is more possible than ever. Note that Grok 4.5 is ahead of Fable for some useful tasks at a much lower cost, so ranking them #3 is conservative.
This is not happening yet. Cheap, mostly open source tokens are likely the majority of volume today but the majority of economic value is still accruing to the most intelligent models. Might change though.
We will see.
Cassandra Unchained@michaeljburry· 11 июл. 2026 г.This is true as I have heard this from contacts in the Valley. Goes with my pinned post.
The AI race is shifting from bigger models to cheaper, smarter systems

For the first time, Starship will carry 20 next-generation Starlink V3 satellites to space
Starlink V3 is designed to massively expand the network’s capacity and increase user speeds
After deployment, the test satellites will:
• Extend their solar arrays and antennas
• Attempt to connect with ground stations in South Africa
• Establish links with the wider Starlink constellation using high-capacity lasers
The satellites will follow the same suborbital trajectory as Starship, meaning they will not remain in orbit and are expected to reenter the atmosphere later in the mission
But the most interesting part is how Starlink will help inspect Starship
Six of the satellites have been modified with cameras designed to scan Starship’s heat shield and transmit the imagery back to SpaceX operators
Several heat-shield tiles have even been painted white to simulate missing tiles and provide clear imaging targets
The goal is to continue testing methods of analyzing Starship’s heat shield readiness for return to launch site on future missions
