Seed 2.0 Mini API: ultra-cheap ByteDance model with 131K output

Seed 2.0 Mini is ByteDance's budget Seed model, pairing rock-bottom pricing with an unusually large 131,072-token output ceiling for high-volume work.

On YepAPI you call Seed 2.0 Mini through one OpenAI-compatible endpoint at $0.15 per 1M input and $0.62 per 1M output tokens, with a 262,144-token context window.

What is Seed 2.0 Mini?

Seed 2.0 Mini is the value tier of ByteDance's Seed 2.0 line, built to run cheaply at scale. What makes it stand out among budget models is that it keeps a 262,144-token context window and a large 131,072-token output ceiling rather than shrinking them, so it can still read big inputs and write long outputs while costing a fraction of flagship rates. It is aimed at the high-volume, lower-complexity work that dominates production systems: classification, extraction, sentiment analysis, and short-to-medium generation across many requests. When economics decide whether a feature is viable, Mini's pricing is its main appeal.

Build with Seed 2.0 Mini via YepAPI

Call Seed 2.0 Mini through YepAPI's OpenAI-compatible /v1/ai/chat endpoint. Point your OpenAI SDK at YepAPI and set the model string to seed-mini; switching to a larger model later is a one-string change. A single YepAPI key also covers every other model plus SEO, SERP, and web-scraping tools, so a pipeline can scrape pages, classify or extract from them cheaply with Mini, and escalate only hard cases to a bigger model, all on one key.

Seed 2.0 Mini API pricing — $0.15 / $0.62 per 1M tokens

Seed 2.0 Mini costs $0.15 per 1M input tokens and $0.62 per 1M output tokens on YepAPI, among the cheapest options on the platform. At those rates you can process millions of records for a few dollars, which makes Mini the natural first stage in tiered pipelines: handle the easy majority cheaply, then route only ambiguous or high-value cases to a costlier model. The large context and output windows mean you rarely give up capability for the savings.

Seed 2.0 Mini for high-volume processing

Seed 2.0 Mini fits bulk, repetitive workloads: classifying product reviews, extracting sentiment keywords, tagging content, and generating short responses across enormous request volumes. Its high throughput clears big batches without backlog, and the 131K output ceiling means it can still produce long documents on the rare calls that need them. For cost-driven, large-scale tasks where good-enough quality at minimal price wins, Mini is the default choice.

New YepAPI accounts include $5 of free credit with no card required. Given Mini's ultra-low rates, that covers a very large test batch, so you can validate accuracy on your own high-volume data before scaling up.
