Hey @AnthropicAI when will you release a model for smart contract auditing ?
Claude@claudeai
Introducing Claude Opus 4.7, our most capable Opus model yet. It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back. You can hand off your hardest work with less supervision.

Today marks 8 years of QuillAudits.
Most Web3 security firms didn't exist 8 years ago. Most won't exist 8 years from now.
We've built through 3 bear markets, 2 exploit waves, and the full evolution of smart contract attacks from simple reentrancy to cross-protocol economic exploits.
1,500+ protocols. $3B+ protected.
The biggest lesson from 8 years and 1,500+ engagements :
One team, one method, one pass doesn't cut it when you're protecting hundreds of millions in user funds.
So we rebuilt the model.
Multi-Layer Audit → four independent security layers, delivered in the same timeline as a traditional audit:
> Senior auditors who've collectively reviewed 1,500+ protocols
> AI security agents trained on 5,000+ real exploits since 2017
> Independent bug bounty through curated security researchers
> Continuous monitoring, because threats don't stop at deployment
4 layers. Each one catches what the others miss.
Web3 has a $100T addressable market if institutions show up. They won't show up until security is embedded in every layer, every transaction, every deployment, the way HTTPS is embedded in the internet.
That's the problem worth solving for the next 8 years.
QuillAudits built the foundation, QuillShield is the next chapter — an AI security agent that brings what we learned from 1,500+ manual audits into every developer's workflow, before code ever hits mainnet.
8 years in. Still early.

@PatrickAlphaC This is a pretty serious thing the impact can be much wider, with prompt injections forcing the AI to run tools, delete databases, make transactions, and through some specific strategies even conceal what the AI is doing so that it gets ignored by users.

I think Grok should automatically flag all videos that appear suspicious and are not real, rather than people tagging and asking, "What do you say about this feature, @grok?"

Benchmark saturation has come; models need harder benchmarks

GPT-5.4 Thinking and GPT-5.4 Pro are rolling out now in ChatGPT. GPT-5.4 is also now available in the API and Codex. GPT-5.4 brings our advances in reasoning, coding, and agentic workflows into one frontier model.

@PatrickAlphaC A prompt injection in any file of a codebase, with medium or low reasoning/safety model, can wreck lives.
