GPT-5.4 wins on coding (90 vs 58) and writing quality and price ($2.5 vs $5/1M input) and context window (272K vs 128K). For most workflows, GPT-5.4 is the stronger default — best for agentic automation and desktop control workflows.
The shortest way to see the safest default, the lower-cost option, and the specialist pick before you read deeper.
GPT-5.4 is the safest overall answer here when you want the strongest default instead of the lowest list price.
Meta: Llama 3.1 8B Instruct is the lower-cost option to start with when you still need useful output at scale.
GPT-4o is the better pick when response speed matters more than maximum reasoning depth.
GPT-5.4 leads on coding with a score of 90 vs 58 for GPT-4o.
GPT-5.4 has the larger context window: 272K vs 128K for GPT-4o.
GPT-5.4 is cheaper at $2.5/1M input tokens vs $5/1M for GPT-4o.
Choose GPT-5.4 for coding and research — agentic workflows.
Choose GPT-4o when multimodal tasks and image-adjacent workflows.
Both models serve different primary workflows — consider using each where it has a clear edge.
Switch the scoring lens to see whether the top answer changes when you care more about cost, speed, or long-document work.
