Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read

Focus sharply on the package details – the slightly soft edges of the paper bag, the texture of the vintage printing, the inviting \"All-Purpose Flour\" text. Subtle hints of the 1960s kitchen frame the shot – the chrome edge of the counter gleaming softly, a blurred glimpse of a pastel yellow ceramic tile backsplash, or the corner of a vintage metal canister set just out of focus.

Emu 3.5
Emu 3.5 occupies the generated-image role in the model catalog for content pipeline engineers. Its practical value is to reduce ambiguity when a workflow chooses among neighboring model variants: an upstream service can confirm that it has prompt, submit one well-scoped job, and receive a generated image asset for downstream approval. This positioning explains when the exact sandbase-ai/emu-3.5 route belongs in an architecture without borrowing promises from another version, tier, or task variant.
A production-minded integration begins by checking the source ownership, expected result, and release checklist. The caller records required values separately from optional choices such as seed, resolution, aspect_ratio, output_format, runs a small representative sample, and stores the route name with the resulting artifact. Reviewers then compare that artifact with the agreed acceptance criteria, document any rejected setup, and promote only a successful request shape into larger batches. This workflow gives sandbase-ai/emu-3.5 measurable business context while leaving the Highlights section to explain model behavior.
Highlights
- Prompt-responsive composition. Emu 3.5 Image turns detailed natural-language art direction into a complete visual with a defined subject, setting, and treatment.
- Style range. The route can interpret photographic, illustrative, graphic, or conceptual direction when those choices are stated clearly in the prompt.
- Layout control. Supported framing and composition controls help Emu 3.5 Image prepare imagery for landscape, square, portrait, or design-specific placements.
- Iteration-ready output. Seed and other declared creative controls make it practical to compare focused variations while retaining the core brief.
Pricing
| Billing option | Price |
|---|---|
| Billing formula | params.resolution == "720p" ? 0.30 : 0.15 |
resolution=720p | $0.300000 |
resolution=480p | $0.150000 |
When to Use
| Scenario | Why it fits |
|---|---|
| Choose Emu 3.5 | Use it when the job specifically calls for emu 3.5 and the route’s documented input contract matches assets already available in your workflow. |
| Keep the request reproducible | Use the required prompt explicitly, then record optional choices alongside the prompt for repeatable reruns. |
| Build controlled creative variations | Change one declared control at a time when comparing framing, format, duration, resolution, style, or other route-supported output decisions. |
| Integrate asynchronous delivery | Use this endpoint when an application can submit work, track completion, and collect the returned media URL instead of requiring an immediate inline artifact. |
| Validate before a large batch | Run representative prompts and source assets first, confirm the visual or audio behavior, then lock the successful request shape for scaled production. |
Prompt Guide
Lead with the subject or transformation, then add the composition, environment, style, lighting, motion, voice, or fidelity details relevant to this route. Keep every parameter inside the documented schema; the example below uses only fields declared for sandbase-ai/emu-3.5.
