Shared compatibility

  • Python · keras: Python runtime · LMFlow: Python runtime

Choose keras if…

  • Tags unique to keras: data-science, neural-networks, machine-learning, tensorflow.
  • More GitHub stars (64k vs 8.5k) - visibility, not fit.

When NOT to use keras

  • Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

Choose LMFlow if…

  • Tags unique to LMFlow: pretrained-models, chatgpt, transformer, language-model.
  • Also covers LLM Frameworks.
  • Leaner open-issue backlog (87).

When NOT to use LMFlow

  • LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
  • Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
Is keras or LMFlow more popular on GitHub?
keras has more GitHub stars (64,191 vs 8,483). Stars measure visibility, not whether either tool fits your constraints.
Are keras and LMFlow open source?
Yes - both are open-source projects on GitHub (keras: Apache-2.0, LMFlow: Apache-2.0).
Where can I find alternatives to keras or LMFlow?
GraphCanon lists graph-backed alternatives at keras alternatives and LMFlow alternatives (keras markdown twin, LMFlow markdown twin), ranked by typed relationship edges rather than popularity votes.
Is there a machine-readable version of this comparison?
Yes. The markdown twin at this comparison mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers.
Which is better maintained, keras or LMFlow?
keras: Very active. LMFlow: Steady. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance.
Where are the full trust reports for keras and LMFlow?
GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: keras trust report; LMFlow trust report.
