Serverless Hosted API V2 is similar to the but provides a GPU-accelerated inference endpoint for model inference. This allows for inferring on GPU-only models such as Florence2, SAM2 etc. and usually reduces the computational latency for Workflow and Inference requests.
In order to use Serverless Hosted API V2 for Workflows select it as the deployment option in the Workflow editor, like so:
The Serverless Hosted API V2 has only one single endpoint

for all models and workflows; this is in contrast to the V1 API which had many different endpoints based on the type of models being inferred.
Also note that the Semantic Segmentation models are not currently supported in V2.

The end-to-end latency of requests sent to the Serverless Hosted API V2 depends on several factors:
Model architecture, which has a bearing on the execution time
Size and resolution of the images that impact upload time and model inference time during execution
Network latency and bandwidth, which affects request upload time and response download time.
Service subscription and usage by other users at any specific time which could result in queueing latency

We encourage users to run their own benchmarks for their model inferences and workflows to get real metrics on their specific usecases.
This sets the inference backend to use Serverless GPU inference. We note that the Serverless Hosted Inference V2 does not currently support (1) (making it unsuitable for video inference). (2) If your workflows use these features then we recommend checkout out.
We show some representative benchmarks performed on the Serverless Hosted API V2 and the Hosted API V1 in the table below. The results for Serverless Hosted API V2 and Hosted Inference (V1) show the end-to-end latency (E2E) as well as the execution time (Exec). These numbers are for information only, we encourage users to perform their own benchmarks using or their own custom benchmarks.
