Seed-2.0-Code or GPT-5.2 Pro: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Seed-2.0-Code for output tokens 56.0x cheaper ($3.00 vs $168.00 per million).
No benchmark has tested both yet. Seed-2.0-Code has none yet; GPT-5.2 Pro on Epoch Capabilities Index, ARC-AGI and ARC-AGI-2. Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.
