Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Cascade monitors terminal output and proposes fixes automatically - compressing feature validation from 40 minutes to 12 minutes per iteration.
Cascade reads assertion errors, inspects related files through multi-file editing, and generates corrected code - often passing on the very first re-run.
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.
