Hosting Caveman for third parties requires a commercial license. - **Requirements:** Min 1 GB RAM; Caveman is primarily written in Go and supports two sizes, allowing for flexible deployment. - **Adopt for:** Caveman reduces token usage by 65% through minimalistic language for coding agents, supporting two sizes and primarily written in Go. - **License detail:** Caveman operates under a split license: MIT for the skill, Agent SDK, and initializer, and BSL-1.1 for the engine-linked runtime, which converts to Apache-2.0 by 2030 or four years after shipping. ## Decision facts: aideml - **Requirements:** Min 4 GB RAM; Requires Docker; Requires Docker for deployment.; Needs an OpenAI API key for full functionality. - **Adopt for:** AIDE is an LLM agent for machine learning engineering, designed for automated machine learning, autonomous agents, and self-improving AI, referenced in OpenAI MLE-bench. ## Choose when ### Choose caveman if… - caveman is primarily Go; aideml is Python. - License: caveman is Other, aideml is MIT. - Pricing: The skill, Agent SDK, and initializer are free under MIT license. Hosting Caveman for third parties requires a commercial license.. - Requirements: Min 1 GB RAM; Caveman is primarily written in Go and supports two sizes, allowing for flexible deployment.. - Tags unique to caveman: anthropic, caveman, claude, claude-code. - When you need to significantly reduce token usage in coding agents, as Caveman can cut usage by 65% through its simplified language style. ### Choose aideml if… - aideml is primarily Python; caveman is Go. - License: aideml is MIT, caveman is Other. - Requirements: Min 4 GB RAM; Requires Docker; Requires Docker for deployment.; Needs an OpenAI API key for full functionality.. - Tags unique to aideml: ai-agents, automated-machine-learning, autonomous-agents, autoresearch. - Also covers Developer Tools. - When you need an LLM agent that focuses on automated machine learning and autonomous agents, as AIDE is specifically designed for these purposes. ## When NOT to use caveman - If your project requires a fully OSI-approved open-source license, as Caveman's engine-linked runtime is BSL-1.1, which is not OSI-approved until a future date. - When you need a tool that does not involve a trademarked name and logo, as Caveman is trademarked and has specific guidelines for its use. ## When NOT to use aideml - If your project does not require integration with OpenAI services, as AIDE's functionality is partly tied to OpenAI APIs. - When you are looking for a tool that does not focus on autonomous agents or self-improving AI, as AIDE is specialized in these areas and may not be as versatile in other aspects of machine learning. ## Common questions ### What is the difference between caveman and aideml? caveman: Reduces token usage by 65% through minimalistic language for coding agents. aideml: AIDE: an LLM agent for machine learning engineering.

When you need a tool that does not involve a trademarked name and logo, as Caveman is trademarked and has specific guidelines for its use. ### When should I avoid aideml? If your project does not require integration with OpenAI services, as AIDE's functionality is partly tied to OpenAI APIs. When you are looking for a tool that does not focus on autonomous agents or self-improving AI, as AIDE is specialized in these areas and may not be as versatile in other aspects of machine learning. ### Is caveman or aideml more popular on GitHub? caveman has more GitHub stars (106,401 vs 1,530). Stars measure visibility, not whether either tool fits your constraints. ### Are caveman and aideml open source? Yes - both are open-source projects on GitHub (caveman: Other, aideml: MIT). ### Where can I find alternatives to caveman or aideml? GraphCanon lists graph-backed alternatives at [caveman alternatives](/tools/juliusbrussee-caveman/alternatives) and [aideml alternatives](/tools/wecoai-aideml/alternatives) ([caveman markdown twin](/tools/juliusbrussee-caveman/alternatives.md), [aideml markdown twin](/tools/wecoai-aideml/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/juliusbrussee-caveman-vs-wecoai-aideml.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, caveman or aideml? caveman: Very active. aideml: Active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for caveman and aideml? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [caveman trust report](/tools/juliusbrussee-caveman/trust); [aideml trust report](/tools/wecoai-aideml/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=juliusbrussee-caveman`](/api/graphcanon/graph?tool=juliusbrussee-caveman) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
