  • Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
  • Volume discounts, private cloud hosting and higher rate limits require a custom plan
  • Standard rate limits are not published

Webpack

  • Complex configuration can be challenging for beginners compared to zero-config alternatives
  • Build times slower than Go-based bundlers like esbuild, especially for large codebases
  • Configuration fragmentation across many plugins increases maintenance burden
