OpenAI's ChatGPT Agent Gets High Bio-Chem Rating Despite Zero Evidence

Everyone assumes AI safety classifications are based on hard evidence. OpenAI just proved that wrong.

Their new ChatGPT agent - the first AI that can actually browse the web and take actions on your behalf - earned OpenAI's "High Biological and Chemical capabilities" rating. The kicker? They openly admit there's "no definitive evidence of enabling novice harm."

So we're classifying AI models based on vibes now?

Let's talk about what's actually happening here. ChatGPT agent runs on an o3-based model and operates in "takeover mode" - essentially controlling a virtual computer and browser to act on your instructions. It can access your logged-in websites, personal data, the works. Think of it as giving your AI assistant the keys to your digital life.

The security challenges are real and messy:

• URL-based data exfiltration where malicious sites trick the agent into sharing your info
• Prompt injection attacks hidden in webpage metadata or invisible elements
• The dreaded "Lethal Trifecta": private data access + untrusted web input + exfiltration vectors

Industry experts have been screaming about this combo since early LLMs. One security researcher called it "unsolved" and warned that unconstrained agents can "cause serious damage."

The Elephant in the Room

Here's what nobody wants to say out loud: we're deploying AI agents before we've solved prompt injection.

OpenAI's own blog post describes prompt injection as a "frontier security challenge" that's persisted into 2026. Yet they're rolling out an agent that processes untrusted web tokens without being able to distinguish between instructions and data.

Their mitigation strategy reads like a security team's wishlist:

1. Specialized training to detect and resist hidden prompts

2. Output filtering and attack monitoring

3. Agent sandboxing with limited network access

4. Human approval for consequential actions

5. Dual-use refusal training (thanks to that High rating)

Does this work? OpenAI says these measures "significantly reduce" risks but admits the overall profile is elevated due to scale and new capabilities. Translation: "We're pretty sure this won't explode, but no promises."

Beyond the Hype

The business implications are fascinating. Albertsons is already using agents for supply chain automation, and legal teams are cutting review times while enforcing confidentiality. The market is clearly hungry for this tech.

But the security community is treating agents like "privileged infrastructure" - recommending logging, anomaly detection, and constant audits. Companies like Kanerika are pushing AgentKit guardrails with PII masking and least privilege access.

The reality? We're in that awkward phase where the technology works well enough to be useful but not well enough to be truly safe. OpenAI's Preparedness Framework Version 2 kicked in, triggering enhanced safeguards and slower rollouts.

My take: The High classification without evidence feels like security theater, but the underlying caution is probably smart. We're essentially beta testing AI agents on the live web with real user data.

The prompt injection problem isn't going away anytime soon. Until we solve the fundamental issue of AI models treating malicious instructions as legitimate commands, every web-connected agent carries this risk.

At least OpenAI is being transparent about it. That's... something.
