Cisco open-sources two small AI models (Antares-350M and Antares-1B) designed to scan codebases for vulnerabilities, running 500 repositories in 15 minutes for under $1 versus $100+ for larger models like GPT-5.5. The models can run locally, keeping sensitive source code on-premise, and are released on Hugging Face with vetting restrictions to prevent adversary access.
This Wire brief sits within Fusion42's coverage of AI Infrastructure, Cybersecurity and Developer Tools.
◆ ◆ The Wire takeaway
If you're selling vulnerability scanning or code security tools, you now compete with free open-source models that cost $1 to run instead of $100, and your customers can deploy them internally without sending code anywhere. Your moat just became narrow unless you're faster, more specialised, or already embedded in their pipeline.
