“Best value”: no other model here reports a higher score at a lower cost for your workload. Scores are self-reported by each maker with different settings, so treat close calls as ties.

How each maker reported it

  • Seed 2.0 Pro Tables 3, 8, 11 (pp.9, 13, 16)

    ByteDance's own runs. Competitor columns are as printed in the Seed2.0 card (frontier models available in early 2026). Codeforces is an Elo rating. HLE-text under Agentic is with search tools.

  • Seed 2.0 Lite Tables 4, 8, 12 (pp.10, 13, 17)

    ByteDance's own runs from the Seed2.0 model card, which predates the 260428 snapshot served now. Codeforces is an Elo rating. Seed 2.0 Mini is shown for comparison (same table).

Only each model's own maker's number is shown; scores a maker reports for rival models are left out.
