ByteDance Seed 2.1 Turbo appears on public model timelines as an Aug 10 2026 API drop. We added a dated seed so “seed 2.1” does not 404. Treat the Elo and SWE-bench cells as bootstrap until OpenRouter and a second source agree. Doubao-branded names are aliases, not a second model.
New marketplace SKUs start as seed, then ingest
If ingest cannot match the OpenRouter id, the row stays on seed-bootstrap. That is visible in the source note. We will not silently paint Arena numbers from a lookalike name.
Empirical Evaluation & Architectural Analysis
Empirical evaluations recorded across the CompareLLM Leaderboard highlight how parameter scaling and inference optimization impact production throughput and cost-per-token economics. Reference the interactive scorecard above for verified snapshots or inspect the dedicated seed-2-1-turbo dossier.
Not a US-default chatbot
If your users are not on that stack, skip it. Regional availability is not a metric we store in v1.
