GPT-5.4 is provided by OpenAI and emphasizes extended context and superior reasoning. Seedream 5.0 Lite, from ByteDance, emphasizes fast generation and high quality. The stronger option depends on the input, output constraints, and review standard.
Run the same prompt, source context, output format, and acceptance criteria through both models. Score accuracy, instruction following, edit time, latency, and current cost separately. Repeat the test on several representative tasks before standardizing on either model.
