GPT-4o vs DBRX Instruct

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

GPT-4o is clearly ahead on the aggregate, 60 to 32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4o is also the more expensive model on tokens at $2.50 input / $10.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for DBRX Instruct. That is roughly Infinityx on output cost alone. GPT-4o gives you the larger context window at 128K, compared with 32K for DBRX Instruct.

Quick Verdict

Pick GPT-4o if you want the stronger benchmark profile. DBRX Instruct only becomes the better choice if coding is the priority or you want the cheaper token bill.
