Choose picoGPT if…

  • picoGPT is primarily Python; caveman is Go.
  • License: picoGPT is MIT, caveman is Other.
  • Requirements: Min 2 GB RAM; PicoGPT may struggle with larger datasets due to its inefficiencies, despite being minimal..
  • Tags unique to picoGPT: deep-learning, gpt, gpt-2, large-language-models.
  • - Use `picoGPT` when you need an example to understand GPT-2's functioning at its most pared-down level.

When NOT to use picoGPT

  • - Avoid `picoGPT` in scenarios requiring efficient batch processing or advanced generation techniques like top-p sampling, as it lacks these features.
  • - Do not use `picoGPT` if speed and scalability are critical for your project, given its megaSlow execution.

Choose caveman if…

  • caveman is primarily Go; picoGPT is Python.
  • License: caveman is Other, picoGPT 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: ai, anthropic, caveman, claude.
  • Also covers AI Agents.
  • caveman ships Docker support for self-hosted deployment.
  • When you need to significantly reduce token usage in coding agents, as Caveman can cut usage by 65% through its simplified language style.

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.
