Specifications
Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.
Context / input limit
Not collected
Not established for this exact Aperture version. Image output and a four-image web request do not establish a language token budget or asynchronous Batch API.
Maximum input tokens
Not collected
Not established for this exact Aperture version. Image output and a four-image web request do not establish a language token budget or asynchronous Batch API.
Maximum output
Not collected
Not established for this exact Aperture version. Image output and a four-image web request do not establish a language token budget or asynchronous Batch API.
The client rejects trimmed prompts longer than 10,000 characters. UI message says “under 10,000”; the condition allows exactly 10,000. This is not a verified server-side limit.

Published client dimension presets, not a verified backend maximum or an upscaled export limit. For historical versions these are retained client tables, not proof of current access.
Starter: $8/month billed annually, 1,000 fast generations/month and two concurrent fast jobs. Pro: $24/month billed annually, 3,000 fast generations/month and three concurrent fast jobs. Max: $48/month billed annually, 7,000 fast generations/month and three concurrent fast jobs. Pro and Max slow queues have a daily cap whose numeric limit is not published here. No free generation plan.Source for Subscription plans (opens in a new tab)
Generation controls
Each prompt submission consumes four image-generation credits. Uploaded-image workflows and variations are present in the UI; exact reference count, byte limits and per-version editing behavior remain unverified.Source for Generation controls (opens in a new tab)
Access & pricing
Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.
Images created on Starter or Pro are public. Max images are private unless shared. Exact storage retention and training-use policy were not established.Source for Creation privacy (opens in a new tab)

Rate conditions
Shared Lexica account plan, not a separate charge for each model. 1,000 fast image generations/month; each prompt submission uses four credits. Annual commitment; not a standalone API rate. No plan-price-to-per-image conversion inferred.
Shared Lexica account plan, not a separate charge for each model. 3,000 fast image generations/month; each prompt submission uses four credits. Annual commitment; not a standalone API rate. No plan-price-to-per-image conversion inferred.
Shared Lexica account plan, not a separate charge for each model. 7,000 fast image generations/month; each prompt submission uses four credits. Annual commitment; not a standalone API rate. No plan-price-to-per-image conversion inferred.
Optional account-wide top-up, usable only with an active plan. Credits do not expire. Each prompt submission consumes four image-generation credits; this is not a per-question or public generation API tariff.
Starter and Pro images are public and may appear in search. Max images are private unless shared. Commercial image use depends on plan and team size. Output-image licensing does not disclose model weights, retention periods or a training opt-out.
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
Private hosted-model classification is inferred from the provider describing its model training work and distinguishing its Aperture model from public Stable Diffusion images, its subscription-only generation service, and no matching weight distribution established in the reviewed first-party sources. This is not an explicit weight-license statement. Exact upstream architecture and derivative ancestry remain unresolved; the output image license is not a weight license.
