DeepSeekDeepSeek V4 FlashVSMetaLlama-3.1 8B
Our Take
We recommend Llama-3.1 8B for practical local execution on standard developer hardware, or DeepSeek V4 Flash if you need peak reasoning and have the VRAM (or a cloud API) to host it. While DeepSeek V4 Flash offers frontier capability, its massive parameter size makes it extremely difficult to host locally. Choose Llama-3.1 8B for standard local setups, or DeepSeek V4 Flash for peak reasoning.
▶WHY?
Benchmark Calculations & Evidence:
Model Size: DeepSeek V4 Flash is a massive 284B parameter model requiring heavy GPU infrastructure, while Llama-3.1 8B is a 8B parameter model.
