Maximum prompt characters
512Source for Maximum prompt characters (opens in a new tab)

Text and negative prompts use character limits; these are not text-token context windows.

Output formats
Base64-encoded image strings in the JSON responseSource for Output formats (opens in a new tab)

Do not confuse the response body’s transport stream with incremental image-generation streaming.

Images per request
5Source for Images per request (opens in a new tab)

numberOfImages ranges from 1 to 5 and defaults to 1.

Image input limits
Maximum 5 MB; task-specific size rules. Variation accepts 1–5 references; editing limits the longer side to 1,408 pixels.Source for Image input limits (opens in a new tab)

Source for Output resolutions (opens in a new tab)

Explicit width/height pairs from the parameter table. It also states 1,408 × 1,408 defaults but does not enumerate that pair; the inconsistency is preserved, not treated as arbitrary-dimension support.

Generation controls

Rate conditions

  1. US East (N. Virginia) selection; published AWS price map 2026-10-14T03:30:16Z. Retained meter for a historical model, not confirmation of service availability. Literal pricing-template bucket label. Boundaries conflict with the image guide and resolution-equivalent table; see source conditions before using a particular size. No availability implied.
  2. US East (N. Virginia) selection; published AWS price map 2026-10-14T03:30:16Z. Retained meter for a historical model, not confirmation of service availability. Separate provisioned-throughput model-unit charge, not a per-image price. Historical eligibility and any private continuation contract must be checked separately.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Amazon identifies Titan as its own foundation model family delivered through Amazon Bedrock. The reviewed original product and API documentation offer managed inference/customization, not downloadable original model weights.
