Seed-2.0-Code or DeepSeek V3: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Seed-2.0-Code for a larger context window (262K against 164K tokens).
No benchmark has tested both yet. Seed-2.0-Code has none yet; DeepSeek V3 on Aider polyglot, SWE-bench Lite and GPQA Diamond (Epoch AI run). 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.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
DeepSeek V3 costs less
Repository review
