## What the models said about Sonatype Nexus Repository

- "Limited integrations vs. leaders; self-host adds ops overhead." (Grok 4.1 Fast, direct prompt, soft negative)
- "Enterprise-grade artifact repository manager that allows development teams to store, organize, and distribute software components... Both are viable for a 500-person company." (Muse Glimmer 30B, scale prompt, first choice)
- "the best artifact repository for a company with a limited budget is Sonatype Nexus Repository (Community Edition)" (GLM 4.7 FlashX, budget prompt, first choice)
- "For most mid-market B2B companies, Sonatype Nexus Repository Pro is the strongest all-around recommendation" (DeepSeek V4 Flash, direct prompt, first choice)

## 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)
