Open-weight models now match frontier cyber performance from just four months ago at a fraction of the cost
The British AI Security Institute warns that open-weight models such as GLM-5.2 and DeepSeek V4-Pro now lag behind closed frontier models in cyber capabilities by only four to seven months, compared to a gap of six to ten months at the start of 2025. The institute also found that safety measures on open models are largely ineffective, reducing the time defenders have to prepare.
Why it matters: The shrinking gap in cyber capabilities between open-weight and frontier models, along with ineffective safety measures, increases security risks.
