Strengths

Flagship of the GPT-5.6 family, served in pro reasoning mode for maximum quality on complex tasks
Leading abstract reasoning: ARC-AGI-2 85.4 at high effort, reaching 90.0 (xhigh) and 92.5 (max) with more reasoning
Frontier agentic coding: 88.8 on Terminal-Bench 2.1 and 64.6 on SWE-bench Pro (single-agent), strong on command-line and long-horizon work
1M-token context window with programmatic tool calling and multimodal (text, image, file) input

Limitations

Pro reasoning mode consumes more tokens per query than base Sol at the same per-token price ($5 / $30), so it uses up quota faster
Trails the current SWE-bench Pro leaders on in-codebase resolution (64.6 vs about 80)
OpenAI published no MMLU, GPQA or math benchmarks for GPT-5.6, so direct comparison with older flagships is harder
