Where each one falls short

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

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

Tabnine

  • No published free tier as of the current pricing page, unlike several competitors that offer free individual plans
  • Pricing is higher than many consumer-focused AI coding assistants, targeting enterprise budgets
  • Now owned by Tricentis, a testing-focused company, introducing uncertainty about long-term product direction outside quality engineering use cases
  • LLM usage costs apply separately when using Tabnine-provided model access, on top of the per-seat license fee
