Everyone's paying for security AI. Meanwhile, some of the most interesting cybersecurity models are sitting on Hugging Face free to download and run yourself. 👀 A few worth checking out 👇 ⒈ → GLM-5.3-CYBERSECURITY : The one everyone's talking about. 44K downloads in 3 weeks. Tuned specifically for offensive security. Catch: 753B parameters. Almost nobody is running this locally. 💀 → RavenX CyberAgent A pentest agent that can call tools, use MCP, and work with MITRE ATT&CK. The ~20GB version can run on a MacBook. → GPT-OSS-Cybersecurity-20B GPT-OSS trained on 50K cybersecurity questions and answers. → BaronLLM v2 14B model focused on offensive security. MIT licensed. → Trendyol v2 70B Llama-based model focused more heavily on defensive / blue-team security. → Llama-Primus-Reasoning Trend Micro's reasoning model, with datasets that have influenced a bunch of security-focused models. → Security-SLM A tiny red/blue-team helper at ~3.4GB. Much easier to run locally. A year ago, most of these would have been called "uncensored chatbots." Now we're seeing security-tuned models, tool-using agents, MCP support and local pentesting workflows. ⚡ And that's probably the more interesting shift.
