DeepSeek vs OPT

Which should you choose?

DeepSeek-V3.2 is the practical choice for users wanting a capable AI assistant today. It delivers strong reasoning and coding performance through accessible web/mobile interfaces with free tier access, though Chinese ownership raises legitimate privacy concerns for sensitive work. OPT is a research artifact—a lightweight 350M parameter model optimized for reproducibility and academic exploration, not production use. DeepSeek dominates on capability (1M token context, 671B parameters, 96th percentile on coding); OPT excels only if you need to run inference locally on constrained hardware or need full source code transparency for research. For commercial applications or complex tasks, DeepSeek wins decisively. For academic AI research needing an open baseline, OPT's value lies in its reproducibility, not performance.
