Pairwise benchmark snapshot · Aug 17, 2026noindex (thin pair)
This page compares Claude Fable 5 (Anthropic) and ByteDance Seed: Seed-2.0-Lite (bytedance-seed) using the latest snapshots we have as of Aug 17, 2026. ByteDance Seed: Seed-2.0-Lite wins on output price at $2/1M. Claude Fable 5 has the larger context window (1M tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.
Anthropic
Claude Fable 5Anthropic top-tier long-horizon model. Official API $10/$50 per 1M tokens (Claude Platform pricing, Aug 2026).
bytedance-seed
ByteDance Seed: Seed-2.0-LiteAuto-discovered from OpenRouter (bytedance-seed/seed-2.0-lite). Preview until a second source matches.
thinking_budgetReasoning models scale test-time compute by generating hidden chain-of-thought (CoT) tokens. These tokens are billed at standard output rates and directly expand latency (TTFT) in exchange for higher GPQA Diamond and SWE-bench Verified problem resolve rates.
