Antares-1B achieves 0.209 File F1 on the Vulnerability Localization Benchmark, outperforming GLM-5.2 (753B parameters) and Gemini 3 Pro, while a full 500-task sweep runs in about 13 minutes on a single H100 for under $1, compared to $141 for GPT-5.5.", "body_md": "Cisco Foundation AI has released Antares, a family of small language models trained to pinpoint where known vulnerabilities live inside a codebase. Antares-1B reaches 0.209 File F1 on the new Vulnerability Localization Benchmark, above GLM-5.2 at 753B parameters and Gemini 3 Pro. The untrained Granite 4.0 checkpoints score near zero under the same protocol, so post-training supplies almost all of the capability. A full 500-task sweep runs in roughly 13 minutes on a single H100 for under a dollar, against $141 for GPT-5.5.\n\nThe post [Cisco Foundation AI Releases Antares: 350M and 1B Open-Weight Models That Localize Known Vulnerabilities Inside Real Codebases](https://www.marktechpost.com/2026/07/21/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-localize-known-vulnerabilities-inside-real-codebases/) appeared first on [MarkTechPost](https://www.marktechpost.com).", "url": "https://wpnews.pro/news/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-known", "canonical_source": "https://www.marktechpost.com/2026/07/21/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-localize-known-vulnerabilities-inside-real-codebases/", "published_at": "2026-07-22 06:27:02+00:00", "updated_at": "2026-07-22 06:56:17.701420+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-research", "ai-safety"], "entities": ["Cisco Foundation AI", "Antares", "GLM-5.2", "Gemini 3 Pro", "Granite 4.0", "GPT-5.5", "H100", "MarkTechPost"], "alternates": {"html": "https://wpnews.pro/news/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-known", "markdown": "https://wpnews.pro/news/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-known.md", "text": "https://wpnews.pro/news/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-known.txt", "jsonld": "https://wpnews.pro/news/cisco-foundation-ai-releases-antares-350m-and-1b-open-weight-models-that-known.jsonld"}}
