Pick Composer 2 if you want the stronger benchmark profile. DeepSeek V3.2 only becomes the better choice if coding is the priority or you want the cheaper token bill.
Composer 2 is clearly ahead on the provisional aggregate, 73 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Composer 2 is also the more expensive model on tokens at $0.50 input / $2.50 output per 1M tokens, versus $0.28 input / $0.42 output per 1M tokens for DeepSeek V3.2. That is roughly 6.0x on output cost alone. Composer 2 is the reasoning model in the pair, while DeepSeek V3.2 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Composer 2 gives you the larger context window at 200K, compared with 128K for DeepSeek V3.2.
Composer 2 is ahead on BenchLM's provisional leaderboard, 73 to 58. The biggest single separator in this matchup is SWE-Rebench, where the scores are 58% and 60.9%.
DeepSeek V3.2 has the edge for coding in this comparison, averaging 60.9 versus 58. Inside this category, React Native Evals is the benchmark that creates the most daylight between them.
