Model availability
Start by checking whether DeepSeek V4 appears in the current Deepinfra model catalog. Confirm the exact variant and identifier before testing: a search term alone cannot tell you which model an endpoint runs.
Treat the listing, the model identifier, and a repeatable prompt as separate checks. Each answers a different question about a possible DeepSeek V4 route.
Best first check for whether a variant is currently listed.

Find the current Deepinfra listing, copy its exact identifier, then try a representative prompt. Keep the prompt and evaluation criteria unchanged when comparing alternatives.
A model name in a search result is not proof of a live endpoint. Let the current listing and your own test results guide the choice.
Option 1
Do not assume a similarly named model is interchangeable.
Variant names and identifiers matter. Check the available models again, or choose a listed alternative and evaluate it as a separate model.
Option 2
Test several examples from your actual workload.
Check factual accuracy, formatting, and failure cases against criteria you set in advance. A single demonstration prompt cannot establish how the model handles edge cases.
Option 3
Use nonsensitive test inputs until you have reviewed the relevant data-handling terms.
A model's capabilities do not answer questions about retention, access, or whether a particular input is appropriate to submit.
If deepinfra deepseek-v4 is the route you are investigating, confirm the currently listed variant before sending a prompt. Then test it on a task with a clear expected outcome, record the identifier you used, and compare the result with an alternative under the same conditions.
Check the current Deepinfra model catalog rather than relying on a search result or this page to confirm availability. If you find a listing, note its full name and identifier; availability and variant labels may change.
Start with the variants actually shown in the catalog and read their current model details. Run the same representative prompts through each candidate, then compare the outputs against the requirements of your task rather than assuming a variant's name predicts its performance.
Record the exact identifier selected for the request and check it against the current listing. A page title, prompt, or generated answer by itself cannot confirm which model produced an output.
Do not substitute a similarly named endpoint without checking what it is. Revisit the catalog for current availability, or select another listed model and run the same evaluation prompts so that the comparison remains meaningful.
