## What the models said about GitHub Packages

- "avoid direct, unrestricted use of public community images from Docker Hub, GitHub Container Registry, npm/PyPI, Artifact Hub" (Muse Glimmer 30B, negative prompt, hard negative)
- "GitHub Packages does not natively support PyPI (Python). If your team writes a significant amount of Python, GitHub Packages will not be a complete solution." (Gemini 3.5 Flash, direct prompt, soft negative)
- "Cons: Often less mature in terms of advanced proxying, virtual repositories, and advanced binary management compared to dedicated tools." (Gemini 3.5 Flash, scale prompt, soft negative)
- "For most small to medium companies, GitHub Packages is often the best choice if you're already using GitHub" (Claude Haiku 4.5, budget prompt, first choice)
- "The Best "All-in-One" Option: GitHub Packages / GitLab Package Registry" (Gemini 3.5 Flash, budget prompt, first choice)
- "Top Recommendation: GitHub Packages" (Kimi K2, direct prompt, first choice)

## What the models said about Sonatype Lifecycle

- "using tools like JFrog Artifactory, Sonatype Nexus, or simple self-hosted Docker Registry instances" (Qwen 3.7 Flash, negative prompt, soft negative)
- "For universal artifact management: JFrog Artifactory or Sonatype Nexus Repository Pro." (Mistral Small, scale prompt, first choice)
- "Sonatype Nexus — strongest security intelligence (proprietary research, high-fidelity scanning)" (DeepSeek V4 Flash, scale prompt, first choice)
