#### Pipe
A Pipe is used to create a "Model" with custom logic and processing. A Pipe will always show up as its own singular model in the OpenWebUI interface.
A Pipe has a single main component called a **pipe function**. This component encapsulates all of the primary logic that the Pipe will perform.
Example
```
class Pipe:
class Valves(BaseModel):
RANDOM_CONFIG_OPTION: str = Field(default="")
def __init__(self):
self.type = "pipe"
self.id = "blah"
self.name = "Testing"
self.valves = self.Valves(
**{"RANDOM_CONFIG_OPTION": os.getenv("RANDOM_CONFIG_OPTION", "")}
)
pass
def get_provider_models(self):
return [
{"id": "model_id_1", "name": "model_1"},
{"id": "model_id_2", "name": "model_2"},
{"id": "model_id_3", "name": "model_3"},
]
def pipe(self, body: dict) -> Union[str, Generator, Iterator]:
# Logic goes here
return body
```
#### Manifold
A Manifold is used to create a collection of Pipes. If a Pipe creates a singular "Model", a Manifold creates a set of "Models." Manifolds are typically used to create integrations with other model providers, such as Anthropic or Groq.
A Manifold has two main components:
##### Pipes Function
This is used to simply initiate a dictionary to hold all of the Pipes created by the manifold.
##### Pipe Function
As referenced above, this component encapsulates all of the primary logic that the Pipe will perform.
Example
```
class Pipe:
class Valves(BaseModel):
PROVIDER_API_KEY: str = Field(default="")
def __init__(self):
self.type = "manifold"
self.id = "blah"
self.name = "Testing"
self.valves = self.Valves(
**{"PROVIDER_API_KEY": os.getenv("PROVIDER_API_KEY", "")}
)
pass
def get_provider_models(self):
return [
{"id": "model_id_1", "name": "model_1"},
{"id": "model_id_2", "name": "model_2"},
{"id": "model_id_3", "name": "model_3"},
]
def pipes(self) -> List[dict]:
return self.get_provider_models()
def pipe(self, body: dict) -> Union[str, Generator, Iterator]:
# Logic goes here
return body
```
Note: To differentiate between a Pipe and a Manifold you will need to specify the type in def init:
```
def __init__(self):
self.type = "pipe"
self.id = "blah"
self.name = "Testing"
pass
```
or
```
def __init__(self):
self.type = "manifold"
self.id = "blah"
self.name = "Testing/"
pass
```
