Show HN: We post-trained a model that pen tests instead of refusing

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

A new AI model has been developed to conduct penetration testing rather than avoiding potentially harmful tasks. This approach aims to identify security vulnerabilities by simulating cyberattacks. The model's training focuses on ethical hacking to improve system defenses.

  1. 1.A pen-testing LLM achieved 85% task completion rate at 300ms latency, enabling automated security assessments without risking prompt refusals in production environments.
  2. 2.70% of AI agent failures stem from poor error handling, requiring engineers to design robust fallback mechanisms when API calls or workflows break mid-execution.
  3. 3.In the Weights assigns strength scores up to 988 based on AI model recall, revealing Macaulay Culkin as the top-ranked name with a 98.8% recognition rate across 10+ models.
  4. 4."AlphaFold co-creator John Jumper moves to Anthropic after 9 years at DeepMind, where his protein-folding AI won a Nobel Prize, signaling intensified talent competition in AI research."

In the Weights is your new AI-centric vanity search

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

In the Weights is a new site that lets people see how well AI models can recall them without using web search, producing clustered descriptions and a comparative “strength score.” Created by Thomas Dimson and Joey Flynn after leaving OpenAI, the tool queries models including Grok, Gemini, GPT, Claude and Llama, while also flagging possible hallucinations and surfacing model-to-model differences.
