Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ClearML

  • Broad scope means more to learn and more to run than a focused tracking tool
  • Self-hosting the server is real infrastructure — database, file storage and web server
  • Documentation quality is uneven across the newer parts of the platform
  • Smaller community than the most popular tracking tools, so fewer worked examples exist

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification
