According to CoinMeta, the open-source 27B cybersecurity model OrcaCyber Nano 1.0 developed by OrcaRouter is specifically designed for cybersecurity work. It supports local vulnerability detection, and there is no need to upload sensitive source code. This model can assist in analyzing decompiled code, checking for program vulnerabilities, and reviewing server logs to identify potential signs of intrusion. Its greatest practical value lies in its ability to run completely offline, eliminating the need for companies to upload their internal source code, customer logs, and unpublicized vulnerability information to the cloud. OrcaCyber Nano boasts 27 billion parameters and can be run with a single 16GB graphics card. Its underlying architecture is highly consistent with that of Qwen3.8-27B, and it may represent a fine-tuning based on the previously released Qwen3.8-27B-uncensored.
