GPT-5.4 mini is the cost-efficient workhorse — cheap, fast and good enough for the bulk of everyday traffic, the free/fallback tier in ChatGPT.
Best for
- High-volume production traffic where cost-per-call dominates
- Chat, summarisation, classification and routing
- Latency-sensitive features that don't need flagship reasoning
How it compares — and the India angle
- Best price/performance in the family — route the majority of an India-focused app's requests here and escalate only when quality demands it.
- Its ~54% SWE-bench means it's not a serious autonomous coder; don't use it for hard multi-step bug-fixing.
- Cheaper still: GPT-5.4 nano for pure routing/classification.
