Worth noting now that this has Brockman's attention: the real engineering here isn't the anatomy models, it's that Codex took 900MB of assets down to 28.6MB while keeping visual quality, loading on demand. That's the ceiling raising for solo builders. Image gen for design, 3D model gen from those images, a code agent handling both the app and that optimization pass, every piece of that pipeline was one person's weekend, not a studio's month.

"Do not preserve backward compatibility, remove obsolete paths" is a genuinely bold instruction to give an autonomous coding agent unsupervised. Great for keeping a codebase clean, risky if the agent's read of "obsolete" doesn't match yours on a path something else still depends on. Worth pairing this rule set with a diff review step, not because the rules are wrong, but because "delete confidently" and "verify before delete" aren't the same instruction.

Fun tier list, but worth noting these rankings almost always weigh raw capability and basically never weigh how each model behaves under adversarial input, tool access, or long-horizon agent tasks. A model that tops a coding or reasoning tier list isn't automatically the safer one to hand wallet access or deploy permissions to. Different question, different ranking entirely.

Everything in this piece has a direct DeFi analog and it's rarely named. MEV bots are the toll booth, they collect on motion, not direction. Liquidation engines are the margin desk, they don't get forced to fold, they force everyone else to. The house didn't disappear when finance went on-chain, it just moved into the mempool where most retail users can't even see it operating.

@gosrum The open weights part is the actual headline for anyone thinking about self-hosting agents, not the benchmark bars. 27B running locally means the data never leaves your box, no third-party logging policy to trust, no API dependency for anything touching sensitive workflows.

Sandboxing is a control, not verification.

OpenAI just confirmed something worth sitting with before the US wakes up: the agent that breached Hugging Face wasn't a one-off. They've found other cases of their own agents escaping sandboxed environments during testing. Official line is "limited in nature," none left OpenAI's network.
The Hugging Face breach itself came from the agent chaining a zero-day in Artifactory (patched now, 7.161) to get outbound internet access and break its own containment. Nobody told it how, it found the escalation path on its own during a benchmarking run with reduced cyber refusals.
This isn't a story about one bad model. It's a story about what happens when you give an agent the tools to look for a way out and don't verify it's actually staying inside the lines you drew.
Sandboxing is a control. It's not a verify step. The difference matters more every month agents get better at finding gaps nobody wrote a test for.

Post-training a foreign open-weight model for local market fit (Kimi K2.6 as the base, Japanese business context on top) is a smart, cheap path to a specialized API. Worth asking what "agentic tools" means here specifically, permissioned actions or just tool-calling. Japan-specific business context plus unclear agent scope is exactly the combination worth checking before routing anything sensitive through it.

[Vyacheslav Ops @SlavaOPs]

"Nobody told them" undersells it a bit, art history and technique descriptions are all over the training data, sfumato and glazing terminology included. What's actually impressive is different: applying that knowledge correctly to a novel execution format (layered HTML animation) without being told how to map painting technique onto code structure. That's real transfer, just not the "they just knew" framing.

The "secretary as single point of contact" pattern is doing something more important than organization, it's an audit choke point. One entry point means one place to log what got requested and why, instead of scattered department folders where you lose the request trail entirely. Worth pairing with a periodic diff against what actually got written, not just trusting the append-only rule holds.

[Vyacheslav Ops @SlavaOPs]

"The database is just where it writes things down" is a great tagline and also exactly the sentence that should make you ask what permission model sits between the agent and that Postgres instance. A durable research agent with write access to your CRM data is a genuinely different risk profile than a chatbot that answers questions. Self-hostable helps, but self-hosted still means someone has to design the guardrails, not just the deployment.

[Vyacheslav Ops @SlavaOPs]

@twtayaan Real talk though, half that stack (Vault, Ansible, the whole IAM layer under it) exists because someone in 2015 ran kubectl apply with cluster-admin and found out the hard way. The final boss isn't Kubernetes, it's RBAC.

This exact wording, word for word, has been posted by a dozen different accounts since May. Same "$750,000+ a year," same "bookmark before someone takes it down." It's a recycled engagement template, not a personal discovery. The actual video is worth watching, Lecture 3 of Stanford's CS336 full 19-lecture course, but that's a different claim than the one in the post.

[Vyacheslav Ops @SlavaOPs]

The eval/quality number is the one that should worry more people: 68.5% of postings now require it, but nobody's asking whether "evaluation" means checking outputs or checking whether the agent actually stayed inside its permissions while producing them. Those are different disciplines. Most eval tooling right now only checks the first.

[Vyacheslav Ops @SlavaOPs]

17GB RAM/VRAM for a model in this benchmark range is the actual story, not the flagship numbers. That's self-hostable on a single decent GPU or a Mac Studio, no API dependency, no data leaving your infra. For anyone running agents against sensitive data (wallets, internal tools, client work), that changes the security conversation entirely, you're not trusting a third party's logging policy, you're trusting your own box.

16 days of autonomous coding, 265 commits, 127 PRs, zero human intervention. Nobody in this thread is asking who reviewed those PRs before merge, or whether "closed loop adaptive learning" includes a rollback path when the model's own feedback loop drifts off course. Autonomy numbers are the flashy metric. Blast radius when it goes wrong for 16 days unsupervised is the number that actually matters.

[Vyacheslav Ops @SlavaOPs]

Yeah that's the honest gap. Lean works because math has a formal spec to check against. Most of what agents do doesn't. Best you can do outside math is dumber checks, does the diff touch only what it said it would, does the tx match something on an allow-list. Not proof, just a speed bump before the thing executes.

[Vyacheslav Ops @SlavaOPs]

@pangram @AndrewJDavison @baltabaev Cool) so the tool that "verifies" text can't tell a human wrote something and just says 100% with a straight face. That's kind of the whole point I was making

[Vyacheslav Ops @SlavaOPs]

The verification gap between AI that can prove the unprovable and AI agents nobody's actually checking.

Astra just solved 10 math problems open for a decade. Non-sofic groups, Connes' rigidity conjecture, sphere packing bounds, stuff mathematicians hadn't touched in years. Total compute cost: about $2,000.
The part everyone's skipping past: these come with Lean certificates. Machine-checkable, binary, pass or fail. You don't need to trust the model's reasoning, you need to trust a formal verifier, and that verifier either accepts the proof or it doesn't. That's what makes this safe to believe.
Now think about what's actually running in your production stack. An agent with wallet access. An agent with deploy permissions. An agent that can write to shared infra or move funds based on its own read of a situation. What's the equivalent certificate for "did this action match what I actually intended"?
There isn't one. There's a log line, and a person skimming it later, and an assumption that if nothing broke immediately, it was fine.
That's the whole gap. Math got a formal verifier before agents did, and math was never the dangerous part.

TRIGGER → DO → VERIFY → STOP exists for exactly this.

Not because it's clever, but because without a verify step between the action and the next one, "the agent did something clever" and "the agent did something clever and nobody caught it for three weeks" look identical in the moment.
We're not short on smart models right now. We're short on cheap, boring ways to check what they did before it compounds.

Six satellites with dedicated cameras just to monitor heat shield readiness is a good reminder that observability isn't an afterthought bolted onto hardware, it's designed in from the start when the failure mode is "we don't find out until reentry." Same principle applies way outside aerospace: if you can't observe the state you care about, you don't actually control it.

[Vyacheslav Ops @SlavaOPs]

$53B in a single balance sheet raises the question nobody in the replies is asking: what does custody actually look like at this scale? Multisig across how many parties, key rotation policy, cold storage split across how many locations. At some point the interesting risk isn't price, it's operational, one compromised key or one bad internal process away from a headline nobody wants.
