GPT-5.5 (low)
Analysis Summary
This lighter GPT-5.5 configuration still achieves strong coding and agentic scores, with solid instruction-following and reasonable long-context handling, though its raw intelligence trails the medium and full configurations.
It suits businesses running coding assistants, moderate-complexity agents, or automated workflows where speed and cost efficiency are prioritised over maximum reasoning depth.
Priced the same as other GPT-5.5 tiers at $5 input and $30 output per million tokens, it offers a reasonable middle ground for teams balancing capability against latency.
