OpenAI accidentally locked cybersecurity researchers out of its restricted AI program

Key points

• OpenAI confirmed a technical error revoked access for a limited number of users from its Trusted Access for Cyber (TAC) program, as first reported by TechCrunch.
• The affected tier is called Daybreak Blue, launched on 10 August 2025, which gives vetted security researchers access to advanced models including GPT-5.6 Sol.
• At least five affected researchers confirmed they live outside the US and Europe, suggesting the glitch may be region-specific.
• OpenAI has asked affected researchers to reapply and complete identity verification again.
• A higher tier called Daybreak Red also exists, giving access to models built specifically for offensive security testing.

Imagine spending weeks proving you are a trustworthy security researcher, passing ID checks, getting cleared by OpenAI itself, and then one morning your access simply vanishes. That is what happened to a number of cybersecurity professionals this week.

Multiple researchers reported on OpenAI's official support forums that when they opened ChatGPT's Cyber page, a message told them their identity could not be verified or their account was "ineligible at this time." OpenAI has confirmed it was their fault.

What is this program and why does it matter?

TAC, which stands for Trusted Access for Cyber, is OpenAI's scheme for giving pre-approved security researchers access to its most powerful AI models with fewer safety guardrails than the public gets. Anthropic, OpenAI's main rival, runs a similar scheme called the Cyber Verification Program.

The logic is straightforward. Cybercriminals are already trying to use AI to find software vulnerabilities and build exploits. Defenders need equally capable tools to find those same flaws first and get them fixed. TAC is meant to be that equaliser.

Daybreak Blue is the current entry tier for individual researchers. According to OpenAI, it supports "vulnerability discovery, secure code review, malware analysis, incident response, and patch validation." Daybreak Red sits above it, offering models purpose-built for offensive security testing.

What went wrong?

OpenAI's own error triggered the lock-outs. One researcher shared an email from OpenAI stating that access to Daybreak Blue had been revoked "due to a technical issue affecting a limited number of users." A separate support thread on OpenAI's forums produced an almost identical explanation.

OpenAI posted publicly that "a limited set of users' access to Daybreak Blue is no longer active and they will need to re-verify to maintain their access."

All five researchers who spoke to TechCrunch about the problem said they are based outside the US and Europe, pointing to a possible geographic pattern in whatever broke.

What should affected researchers do?

Re-verify. OpenAI is asking locked-out users to go through the TAC application process again, which means submitting ID and completing vetting a second time.

It is inconvenient, but the company is framing it as a one-time fix rather than a policy change. Nobody is being permanently removed from the program.

One broader tension sits behind this story. In recent months, security researchers working both defensively and offensively have publicly complained that even TAC's loosened guardrails still block legitimate work. That debate will keep running well past this week's glitch.

Common questions

Does this mean OpenAI is restricting researchers more than before?

No. OpenAI says this was a technical error, not a policy decision. Researchers who re-verify should regain the same access they had before.

Can ordinary ChatGPT users access these reduced-restriction models?

No. Daybreak Blue and Daybreak Red are only available to researchers who pass OpenAI's identity and vetting checks. Standard ChatGPT accounts are unaffected by this issue.
