This illustrates a widespread problem affecting large language models (LLMs): even when an English-language version passes a safety test, it can still hallucinate dangerous misinformation in other ...

The GPT-5.3 and 5.4 models represent a different approach, hinting at a major change in how major AI firms build their tech.

OpenAI’s GPT-5.4 mini and nano models cut costs and latency while staying close to flagship performance, giving developers faster AI options for real-time apps without sacrificing core capabilities.

Abstract: A gate leakage current model for p-GaN HEMT is proposed and implemented in a charge-based compact model framework for the first time. Gate leakage mechanisms such as thermal assisted ...

Abstract: This article proposes a parameter extraction method for gallium nitride (GaN) p-i-n diodes and studies the scalability of device parameter models in microwave circuit design. Established ...
