Best for
  • Researchers and students fine-tuning open models
  • Indie developers and startups on a budget
  • ML engineers optimizing training cost
  • Developers on large codebases
  • Terminal-first engineers
  • Teams wanting reviewable AI edits
Pros
  • Free, permissive Apache 2.0 open-source core
  • Large speedups and major memory savings
  • Runs on consumer and free-tier GPUs
