OrcaCyber Zero 1.5 uses a 1 million token context window, tool calling, and extended reasoning to investigate vulnerabilities and validate fixes.

Continuum AI announces in a press release OrcaCyber Zero 1.5, a cybersecurity reasoning model for vulnerability discovery, attack path investigation, exploit validation, and remediation. The model includes a 1 million token context window, native tool calling, and extended reasoning for analyzing large code repositories, security logs, and investigation records.

Continuum AI reports that OrcaCyber Zero 1.5 scored 95.8% on CVE Bench, completing 23 of 24 evaluable tasks. It also scored 100% across 39 unrestricted Cybench challenges and 93.9% on HumanEval+.

In controlled demonstrations, the model reproduced vulnerabilities involving SQL injection, access control, cross site scripting, checkout logic, and prompt injection. It also discovered a vulnerability, generated a patch, and verified the fix with tests.

OrcaCyber Zero 1.5 is available through OrcaRouter, with model access offered by request. Continuum AI also plans to release an open weight cybersecurity model for local deployment next week.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
