Best forPython teams training custom deep learning modelsTeams with dedicated ML engineers
Who it's not forTeams with no Python or ML engineersML beginners and students
PrivacyMultiple public CVEs since 2025, mostly in model loading; Keras maintains a security policy page.Active CVE history . DoS flaws, out-of-bounds reads, and a 2024 Keras RCE; patch promptly and never expose unpatched endpoints.16
Support qualityNo support evidence found.No support-quality evidence found
Public sentimentUsers praise Keras for fast, beginner-friendly prototyping; some find it less flexible than raw frameworks.³Users praise the free, powerful toolkit but consistently call it difficult, and ML community chatter now favors PyTorch.11
Biggest gotchaOnly load model files you trust; loading untrusted files enabled RCE attacks.Keras RCE (CVE-2024-3660) . never expose unpatched model endpoints publicly16

Pick Keras when

  • Python teams training custom deep learning models
  • ML beginners who want simple model code
  • Teams wanting one API across TF, JAX, PyTorch
  • Researchers prototyping fast

When Keras is not a fit

  • Teams with no Python or ML engineers
  • Buyers wanting a no-code or managed AI product
  • Anyone needing vendor SLAs or support contracts

Pick TensorFlow when

  • Teams with dedicated ML engineers
  • Production model deployment at scale
  • Cost-sensitive teams wanting open source
  • Enterprise AI programs

When TensorFlow is not a fit

  • ML beginners and students
  • Research teams . PyTorch dominates there
  • Small teams without ML expertise
  • Anyone wanting no-code AI
