■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

Cisco released two open-weight AI models, Antares-350M and Antares-1B, designed to identify known vulnerabilities in codebases. The company plans to release a larger Antares-3B model soon.

The models perform comparably to significantly larger language models, including OpenAI's GPT-5.5 and Z.ai's GLM-5.2, according to Cisco. Antares represents Cisco's effort to democratize security tooling through open-source AI. By releasing models of varying sizes, the company enables developers to run vulnerability detection locally without reliance on proprietary solutions. The open-weight approach allows organizations to fine-tune models for their specific codebases and security requirements. This contrasts with closed-source alternatives that limit customization and transparency. The roadmap includes Antares-3B, which will offer additional capability for security teams managing larger codebases. Cisco's release aligns with broader industry trends toward open-source AI models and developer-focused security tools. No pricing or exact release date for Antares-3B was disclosed.
