Send a Messages request and get the assistant's response.
|
|
|
|
##### cURL example
|
|
|
|
```
|
|
curl http://localhost:1234/v1/messages \
|
|
-H "Content-Type: application/json" \
|
|
-H "x-api-key: $LM_API_TOKEN" \
|
|
-d '{
|
|
"model": "ibm/granite-4-micro",
|
|
"max_tokens": 256,
|
|
"messages": [
|
|
{"role": "user", "content": "Say hello from LM Studio."}
|
|
]
|
|
}'
|
|
```
|
|
|
|
If you have not enabled Require Authentication, the `x-api-key` header is optional.
|
|
|
|
##### cURL (streaming)
|
|
|
|
```
|
|
curl http://localhost:1234/v1/messages \
|
|
-H "Content-Type: application/json" \
|
|
-H "x-api-key: $LM_API_TOKEN" \
|
|
-d '{
|
|
"model": "ibm/granite-4-micro",
|
|
"messages": [{"role": "user", "content": "Hello"}],
|
|
"max_tokens": 256,
|
|
"stream": true
|
|
}'
|
|
```
|
|
|
|
You will receive SSE events such as `message_start`, `content_block_start`, `content_block_delta`, `content_block_stop`, `message_delta`, and `message_stop`.
|
|
|
|

|
|
|
|
```
|
|
curl http://localhost:1234/v1/messages \
|
|
-H "Content-Type: application/json" \
|
|
-H "x-api-key: $LM_API_TOKEN" \
|
|
-d '{
|
|
"model": "ibm/granite-4-micro",
|
|
"max_tokens": 1024,
