ByteDance Doubao Seed 2.0 Lite — cost-efficient variant with tiered pricing.
Doubao Seed 2.0 Lite (260215) is TheRouter's ByteDance/BytePlus route for the February 2026 Seed 2.0 Lite snapshot. It is exposed as bytedance/doubao-seed-2.0-lite-260215, a text-in/text-out OpenAI-compatible chat model with a 262,144-token context window, 8,192-token maximum completion budget, tool calling, JSON response formatting, and no declared long-context price tier for this exact snapshot in the public catalog.
Use this page differently from the older doubao/doubao-seed-2-0-lite China-branded route: this bytedance namespace is the verified BytePlus / ModelArk-facing snapshot and its official pricing ledger names seed-2-0-lite-260215 directly. For operators, the model belongs in the cost-efficient text tier for classification, routing, moderation, extraction, and summarization where exact snapshot pinning matters more than frontier reasoning depth.
BytePlus / ModelArk lists the underlying seed-2-0-lite-260215 as callable, but the reviewed official pricing table only publishes later Lite snapshots, not this exact 260215 row.
TheRouter exposes the route as an OpenAI-compatible chat-completions model and records the stored token price in standard-models.yaml. A long-context price and cache-hit billing are not exposed on this public model row.

}'The internal ByteDance rate-card sweep records seed-2-0-lite-260215 as callable but blocked for official price correction, because BytePlus publishes pricing for later Lite snapshots rather than the exact 260215 row.
bytedance/doubao-seed-2.0-lite-260215 the same page as doubao/doubao-seed-2-0-lite?No. They are related Lite routes, but this page is the exact ByteDance / BytePlus 260215 snapshot in the bytedance namespace. Use the exact id shown on the page in production configuration and evaluations.
Do not assume a verified higher prompt-length band for this exact model. The local catalog stores 262,144 context, but the reviewed BytePlus pricing table does not publish an official 260215 Lite long-context row, so operators should treat 128K+ margin as unverified.
This scheduled curation loop has no paid API budget. The snippet verifier intentionally requires an operator-set SNIPPET_VERIFY_APPROVED=1, so snippets remain unproven until a human approves and funds a live run.
