AI-Scientist vs EvoScientist

AI-Scientist is much bigger: 14.5k stars against 4.6k. Over the days we have tracked them AI-Scientist moved +1.6% and EvoScientist +7.2%, so EvoScientist is growing faster right now.

They split the axes: AI-Scientist leads on model freedom, EvoScientist on customization.

Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.

Where they stand today

Automates end-to-end scientific discovery by generating hypotheses, running experiments, and producing full LaTeX papers from templates.

Six axes, head to head

Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.

AxisAI-ScientistEvoScientist
Context depth
How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository.
Template-level view
Diff + related files
Noise control
How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only.
Ensemble reviews
Basic filtering & gating
Customization
How far it bends to your team: custom rules, prompts, style guides, per-path config.
Template + prompt config
Extensible skills & config
Privacy
Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only.
Self-hostable (local GPU)
Self-hostable
Model freedom
Whether you can point it at any provider, or it is wired to one.
BYOK + local models
Multiple cloud providers
Setup ease
What it takes to get a first useful run out of it.
GPU + dependencies
Config + API key

Which one to pick

Pick AI-Scientist if…

End-to-end experiment automation — pick this when you want a research-focused system that generates ideas, runs experiments on local GPUs, and compiles full papers automatically.

  • Model freedom: BYOK + local models (5/5 against 3/5)
Runs in cli. Works with byok, openai, anthropic, gemini, other-fixed.

Pick EvoScientist if…

Self-evolving research — pick EvoScientist when you want an opinionated, multi-agent system that autonomously builds a persistent knowledge graph and drafts reusable skills for iterative scientific workflows.

  • Customization: Extensible skills & config (5/5 against 3/5)
Runs in cli, web-app. Works with byok, openai, anthropic, other-fixed.
