ByteDance Doubao Seed 2.0 Mini — ultra-low-cost variant with tiered pricing.
Doubao Seed 2.0 Mini (260215) is TheRouter's ByteDance/BytePlus route for the February 2026 Seed 2.0 Mini snapshot. It is exposed as bytedance/doubao-seed-2.0-mini-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 prompt-length pricing tiers above 128K tokens.
Use this page differently from the older doubao/doubao-seed-2-0-mini China-branded route: this bytedance namespace is the verified BytePlus / ModelArk-facing snapshot and its official pricing ledger names seed-2-0-mini-260215 directly. For operators, the model belongs in the high-QPS, low-cost tier for classification, routing, moderation, extraction, and short summarization where exact snapshot pinning and long-context margin controls matter more than frontier reasoning depth.
BytePlus / ModelArk publishes the underlying seed-2-0-mini-260215 pricing surface with prompt-length tiers and cache-hit pricing in the official rate card.
TheRouter exposes the route as an OpenAI-compatible chat-completions model and records the base plus long-context token prices in standard-models.yaml. Cache-hit billing is not exposed on this public model row.
| Type | Rate |
|---|---|
| Prompts up to 128K tokens | |
| Input | $0.108 / 1M tokens |
| Output | $0.432 / 1M tokens |
| Cached input | $0.108 / 1M tokens |
| Prompts over 128K tokens | |
| Input | $0.216 / 1M tokens |
| Output | $0.864 / 1M tokens |
| Cached input | $0.216 / 1M tokens |
Tiered pricing: when a request's prompt (input, cached tokens included) is over 128K tokens, every token in that request is billed at the long-context rates; exactly 128K is still the base rate. This model publishes no separate cached-input price: cached tokens are billed at the input rate of their group (the "Cached input" row shows that rate).

}'The internal ByteDance rate-card sweep records the official BytePlus USD pricing for seed-2-0-mini-260215: $0.10/$0.40 per million tokens in the base prompt band and $0.20/$0.80 above 128K tokens.
bytedance/doubao-seed-2.0-mini-260215 the same page as doubao/doubao-seed-2-0-mini?No. They are related Mini 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.
The verified BytePlus ledger and TheRouter YAML both record a higher prompt-length band. For prompts over 128,000 tokens and up to the 256K range, input and output prices double to $0.20 and $0.80 per million tokens respectively.
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.
