Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
GPT-5.4 nano and K-Exaone finish on the same overall score, so this is less about a single winner and more about where the edge shows up. The headline says tie; the benchmark table is where the real choice happens.
GPT-5.4 nano gives you the larger context window at 400K, compared with 256K for K-Exaone.
Treat this as a split decision. GPT-5.4 nano makes more sense if coding is the priority or you need the larger 400K context window; K-Exaone is the better fit if its strengths line up with your actual workload.
