Check Existing Issues

I have searched for any existing and/or related issues.
I have searched for any existing and/or related discussions.
I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
I am using the latest version of Open WebUI.

Confirmation

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

curl --location --request POST 'http://localhost:11435/api/generate'
--header 'Content-Type: application/json'
--data-raw '{
"model": "gemma3:4b",
"keep_alive": 0
}'
{"model":"gemma3:4b","created_at":"2026-03-05T10:51:52.284097808Z","response":"","done":true,"done_reason":"unload"}%

Actual Behavior

curl --location --request POST 'http://localhost:3000/ollama/api/generate'
--header 'Content-Type: application/json'
--data-raw '{
"model": "gemma3:4b",
"keep_alive": 0
}'
{"detail":[{"type":"missing","loc":["body","prompt"],"msg":"Field required","input":{"model":"gemma3:4b","keep_alive":0}}]}

Check https://ollama.apidog.io/unload-a-model-14808502e0 for the api spec.

Steps to Reproduce

start owui via docker.
add a model (gemma3:4b)
call ollama service via docker image started by owui docker compose.

curl --location --request POST 'http://localhost:11435/api/generate'
--header 'Content-Type: application/json'
--data-raw '{
"model": "gemma3:4b",
"keep_alive": 0
}'

observe that the request succeeds:
{"model":"gemma3:4b","created_at":"2026-03-05T10:51:52.284097808Z","response":"","done":true,"done_reason":"unload"}%

now do the same but call ollama with owui as the proxy:

curl --location --request POST 'http://localhost:3000/ollama/api/generate'
--header 'Content-Type: application/json'
--data-raw '{
"model": "gemma3:4b",
"keep_alive": 0
}'

observe failure:
{"detail":[{"type":"missing","loc":["body","prompt"],"msg":"Field required","input":{"model":"gemma3:4b","keep_alive":0}}]}
