Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Train Private code models on internal repos so completions match your proprietary architecture. Code review cycles drop 40% from reduced framework mismatches.
Local/cloud models run entirely on-premise at sub-200ms latency. Zero code snippets leave the network - meets HIPAA and FedRAMP data retention requirements.
