Why ByteDance via Synthorai

  • Pay-as-you-go, no subscription. One key, every model; no ByteDance account required.
  • Zero prompt retention. Zero prompt retention at the gateway by default; ByteDance's API data policies apply upstream. Details →
  • Prompt caching. Implicit prefix caching is on by default for Seed language models (1,024-token minimum, no storage fee); an explicit context-caching API is also available. Media models (image / ASR) are not cacheable. Cache reads from $0.02/M.

About ByteDance

ByteDance's model line on Synthorai centers on media: the flagship Seedream family for image generation and Seed ASR for speech-to-text, alongside the Seed family of language models (Dola-Seed 2.0 tiers and ByteDance-Seed 1.8). Per-image and per-minute pricing is flat and published below, on the same OpenAI-compatible endpoints as every other model on the gateway.

FAQ

How do I get a ByteDance API key without a subscription?

You don't need a ByteDance account: sign up on Synthorai, create one API key, and every ByteDance model on this page works through the OpenAI-compatible endpoint: pay-as-you-go, no subscription (models marked "invited beta" additionally need an approved application).

What does the ByteDance API cost?

Token-billed models start at $0.1/M input tokens; every model's live per-unit price is in the table above. These are provider list prices with no platform markup.

Can I use my own ByteDance key (BYOK)?

BYOK isn't available for ByteDance yet; requests run on Synthorai's managed channels at the listed rates.

What is ByteDance's data-retention policy via API?

Zero prompt retention at the gateway by default; ByteDance's API data policies apply upstream.
