Multimodal guide

Validate multimodal input before you build around it.

Input support can vary by provider route, account, content type, request format, and time. Confirm the active Tokenra behavior with safe test data before making it a product dependency.

Verify multimodal support on the exact Tokenra route.

Do not assume that a model label exposes the same input formats through every provider. Check the active Tokenra documentation and safely test the accepted request shape, MIME types or URL rules, file or payload limits, supported content types, and response behavior for the account and route you intend to use.

Start with a small non-sensitive example. Keep a versioned record of the model ID, endpoint, date, request body, and response status. If the route rejects or ignores a content part, treat that as a compatibility finding—not as an invitation to work around a provider restriction with unreviewed transformations.

Data boundary

Protect inputs before they leave your system.

Images, video, documents, and attachments often contain more sensitive information than plain prompts. Classify data before sending it to a third-party route. Remove unnecessary identifiers, follow your organization’s retention and privacy requirements, and avoid exposing private URLs that the provider should not retrieve.

Use server-side request construction and allowlisted sources. Validate file size, type, origin, and metadata at your application boundary. If a provider expects a remote URL, understand who can fetch it, how long it remains accessible, and whether a signed or internal link would create unintended exposure.

Multimodal input expands the attack surface. File parsers, URL fetches, metadata, OCR-like extraction, and retrieved instructions each need the same validation and permission design as any other external input.
Representative evaluation

Test behavior with examples that resemble the product.

Build a small set of approved fixtures covering normal input, poor quality input, missing content, contradictory text and image cues, oversized content, unsupported format, and an input that should be rejected. Score the result against a clear task: extraction, classification, explanation, or another bounded outcome.

Measure error messages, latency, cost, output format, and the quality of the application’s fallback path. A route that is capable of accepting content is not necessarily suitable for every reliability or privacy requirement.

Product design

Design fallbacks before multimodal input becomes critical.

Make it clear when an input was not processed. Offer an alternative path such as text-only submission, a manual review queue, or a retry after a user corrects the attachment. Avoid silently discarding a content part while presenting an answer as if it incorporated it.

Keep the model response separate from any decision to store, publish, forward, or act on information extracted from an attachment. Use human review and conventional validation for high-impact outcomes. For request-shape basics, return to the Ox Alpha API reference.

FAQ

Multimodal API input questions.

Does a model name guarantee image or video support?

No. Verify the active provider route, account availability, accepted format, and request shape before you make a product promise.

Is it safe to pass a user-uploaded URL directly to a provider?

Not without validation. Consider whether the URL is publicly reachable, could expose private content, resolves safely, and complies with your data-handling rules.

What should happen if multimodal input fails?

Show a clear error or fallback, preserve the user’s work where appropriate, and do not imply that an attachment influenced an output when it was not processed.

Start with an approved, small test fixture.

Confirm the route’s current capability before using it in a user-facing flow.
