VectraYX-Nano: New AI Tool for Spanish-Language Cybersecurity
Researchers have developed VectraYX-Nano, a small language model with 42 million parameters specialised in Spanish-language cybersecurity. The model is designed to assist with cybersecurity tasks and integrate tool usage.
What happened?
VectraYX-Nano is a new language model with 42 million parameters, trained from scratch in Spanish. It focuses on cybersecurity, specifically with a Latin American orientation. The model also features native tool invocation capabilities via the Model Context Protocol (MCP). The research was published on 23 May 2026.

”We present VectraYX-Nano, a 41.95M-parameter decoder-only language model trained from scratch in Spanish for cybersecurity, with a Latin-American focus and native tool invocation via the Model Context Protocol (MCP).”
”Corpus: VectraYX-Sec-ES, a 170M-token Spanish corpus from an eight-VM pipeline (~$25 USD) partitioned into conversational (42M tokens, OpenSubtitles-ES, OASST1), cybersecurity (118M tokens, NVD, Wikipedia-ES, CVE mirror, security blogs), and offensive-security tooling (10M tokens”
Why it matters
The development of VectraYX-Nano is significant as it addresses a clear need for specialised AI tools in Spanish-language cybersecurity. By focusing on this specific language and domain, the model can streamline analysis times and improve protection against digital threats for Spanish-speaking users and organisations, reducing linguistic barriers in a critical field.
Who is affected?
Cybersecurity analysts, IT professionals, businesses, and individuals in Spanish-speaking regions are affected. Particularly in Latin America, the model can facilitate the understanding and management of security incidents, and automate certain processes through its tool-use capabilities.
Impact on the EU
Not relevant for EU status. The model is primarily developed with a focus on Spanish and Latin America.
What else you should know
The training corpus, VectraYX-Sec-ES, consists of 170 million tokens and its collection cost approximately $25 USD. The model is distributed under the Apache 2.0 license.
