gpt-oss-120b offers 64% better value per quality point. At 1M tokens/day, you'd spend $2.70/month with gpt-oss-120b vs $7.50/month with GPT-4.1 Nano - a $4.80 monthly difference.

Latency & Speed
GPT-4.1 NanoFaster
Speed score0/100
gpt-oss-120b
Speed score0/100

Both models have comparable response speeds. For most applications, the latency difference is negligible.

When latency matters most: Interactive chatbots, IDE code completion, real-time translation, and user-facing applications where response time directly impacts experience. For batch processing, background summarization, or offline analysis, latency is less critical.
