alt Hacker NewsEveryone talked about the marketing stunt that was Anthropic's gated Mythos model with an 83% result on CyberGym. OpenAI just dropped GPT 5.5, which scores 82% and is open for anybody to use.
I recommend anybody in offensive/defensive cybersecurity to experiment with this. This is the real data point we needed - without the hype!
Never thought I'd say this but OpenAI is the 'open' option again.

Compared to Anthropic, they always have been. Anthropic has never released any open models. Never released Claude Code's source, willingly (unlike Codex). Never released their tokenizer.
Doesn't OpenAI get mad if you ask cybersecurity questions and force you to upload a government ID, otherwise they'll silently route you to a less capable model?

From my experience OpenAI has become very sensitive when it comes to using their tools for security research. I am using MCP servers for tools like IDA Pro or Ghidra (for malware analysis) and recently received a warning:
> OpenAI's terms and policies restrict the use of our services in a number of areas. We have identified activity in your OpenAI account that is not permitted under our policies for: - Cyber Abuse
I raised an appeal which got denied. To be fair I think it's close to impossible for someone that is looking at the chat history to differenciate between legitimate research and malicious intent. I have also applied for the security research program that OpenAI is offering but didn't get any reply on that.
it's still somewhat gated behind "trusted access" for cyber, see https://chatgpt.com/cyber
isnt it like cyber question are being routed to dumper models at openai?
Being "more" open than something totally closed doesn't make you open. The name is still bs
> Anthropic's gated Mythos model
aka the perfect marketing ploy
I ignore any hype news.
Anthropic is the embodiment of bullshitting to me.
I read Cialdini many decades ago and I am bored by Anthropic.
OpenAI is very clever. With the advent of Claude OpenAI disappeared from the headlines. Who or what was this Sam again all were talking about a year ago?
OpenAI has a massive user advantage so that they can simply follow Anthropic’s release cycle to ridicule them.
I think it is really brutal for Anthropic how they are easily getting passed by by OpenAI and it is getting worse with every new GPT version for Anthropic.
OpenAI owns them.
The real 'hype' was that the oh-snap realization that Open AI would absolutely release a competitive model to Mythos within weeks of Anthropic announcing there's, and that Sam would not gate access to it. So the panic was that the cyber world had only a projected 2 weeks to harden all these new zero days before Sam would inevitably create open season for blackhats to discover and exploit a deluge of zero-days.
