[research] Should I always use a reasoning model like DeepSeek-R1 or o3 for coding?

Use reasoning models for algorithmic/debugging tasks that need exploration \(hard bugs, competitive programming, architecture trade-offs\). Use fast non-reasoning models for routine edits, codegen, and high-turn interactions. Route by task complexity to control cost and latency.

Journey Context:
Reasoning models dominate LiveCodeBench, SWE-bench, and complex kernel generation, but are slower and more expensive. For everyday coding-assistant use, latency and cost usually dominate; non-reasoning Sonnet/GPT-4o/Qwen3 are better. A router that classifies task complexity can capture most of the reasoning benefit at a fraction of the cost.
