Pricing and controls
Made by ByteDance
cost = $0.045 + $0.03 × reference images (text only $0.045, one reference $0.075, ten $0.345). Same price for 1K and 2K; no token, size or watermark fees.
Market list prices in USD before the TokenRex discount; your wallet is charged in its own currency using TokenRex's standard conversion. A hold is placed before the job starts, settled once when it finishes, and released if it fails. No cache discounts apply.
Controls TokenRex accepts
- prompt — required.
- image — one URL/data URL or an ordered list of 1–10; all are kept in order. Editing requires at least one.
- size — 1K, 2K or WIDTHxHEIGHT (for example 1536x864). watermark — boolean.
- Always one JPEG (n omitted or 1). Not supported: quality, masks, transparency, output format, GIF/SVG, seed, negative prompt.
- POST /v1/images/edits accepts the same JSON or multipart (model, prompt, size, watermark, repeated image[] files).
Send controls inside input (preferred) or flat beside model — never both. Unknown fields are refused.

Errors
400 invalid_request_errorA control is missing, out of range or not supported (unknown fields are refused, never ignored). Nothing is charged.402 insufficient_balanceYour wallet cannot cover the hold. Nothing is sent to the model.502 outcome_unknownThe connection broke while creating the job, so TokenRex cannot tell whether it started. It is never retried automatically; check your wallet history before sending again.Features and tool support
TokenRex’s exposed interface, not every feature advertised by the provider. “Available” describes the implemented interface, not a successful test of every input or tool.
Input through TokenRex
AvailablePrompt plus up to 10 ordered reference images on POST /v1/images/generations or /v1/images/edits (JSON or multipart).
Output through TokenRex
AvailableExactly one JPEG as base64. Functional tests: text-to-image and a one-reference edit both returned images.
Quality, masks, transparency, formats
Not exposedNot supported by this model and refused if sent.
Sources and verification
Provider specifications describe the upstream model, not a guarantee of every feature through TokenRex. Prices come from the enabled catalog; benchmark results belong to the exact tested model.

Research notes (3)
- Functional test through TokenRex (2026-11-11): a 1K text-to-image request returned an 832×1248 JPEG poster with the requested headline, and a one-reference edit returned the edited JPEG. These are working checks, not quality benchmarks.
- 1K and 2K set the output scale and are not exact squares; a custom WIDTHxHEIGHT size such as 1536x864 is accepted.
- Quality, masks, transparency, output format, seed, negative prompts and multiple outputs are not supported and are refused.
