Choose keras if…
- keras is primarily Python; CTranslate2 is C++.
- License: keras is Apache-2.0, CTranslate2 is MIT.
- Tags unique to keras: data-science, neural-networks, machine-learning, python.
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 CTranslate2 if…
- CTranslate2 is primarily C++; keras is Python.
- License: CTranslate2 is MIT, keras is Apache-2.0.
- Tags unique to CTranslate2: avx, cpp, cuda, deep-neural-networks.
When NOT to use CTranslate2
- 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.
