Authentication

API Keys

For authentication with an API key, pass it during the client initialization:

from aidial_client import Dial, AsyncDial

dial_client = Dial(api_key="your_api_key", base_url="https://your-dial-instance.com")

async_dial_client = AsyncDial(
    api_key="your_api_key", base_url="https://your-dial-instance.com"
)

You can also pass api_key as a function without parameters, that returns a string:

def my_key_function():
    # Any custom logic to get an API key
    return "your-api-key"


dial_client = Dial(api_key=my_key_function, base_url="https://your-dial-instance.com")

async_dial_client = AsyncDial(
    api_key=my_key_function, base_url="https://your-dial-instance.com"
)

For async clients, you can use coroutine as well:

async def my_key_function():
    # Any custom logic to get an API key
    return "your-api-key"


async_dial_client = AsyncDial(
    api_key=my_key_function, base_url="https://your-dial-instance.com"
)

Bearer Token

You can use a Bearer Token for a token-based authentication of API calls. Client instances will use it to construct the Authorization header when making requests:

from aidial_client import Dial, AsyncDial


# Create an instance of the synchronous client
sync_client = Dial(
    bearer_token="your_bearer_token_here", base_url="https://your-dial-instance.com"
)

# Create an instance of the asynchronous client
async_client = AsyncDial(
    bearer_token="your_bearer_token_here", base_url="https://your-dial-instance.com"
)

You can also pass bearer_token as a function without parameters, that returns a string:

def my_token_function():
    # Any custom logic to get an API key
    return "your-bearer-token"


dial_client = Dial(
    bearer_token=my_token_function, base_url="https://your-dial-instance.com"
)

async_dial_client = AsyncDial(
    bearer_token=my_token_function, base_url="https://your-dial-instance.com"
)

For async clients, you can use coroutine as well:

async def my_token_function():
    # Any custom logic to get a bearer token
    return "your-bearer-token"


dial_client = Dial(
    bearer_token=my_token_function, base_url="https://your-dial-instance.com"
)

List Deployments

If you want to get a list of available deployments, use client.deployments.list() or method:

>>> client.deployments.list()
[
    Deployment(id='gpt-35-turbo', model='gpt-35-turbo', owner='organization-owner', object='deployment', status='succeeded', created_at=1724760524, updated_at=1724760524, scale_settings=ScaleSettings(scale_type='standard'), features={'rate': False, 'tokenize': False, 'truncate_prompt': False, 'configuration': False, 'system_prompt': True, 'tools': False, 'seed': False, 'url_attachments': False, 'folder_attachments': False, 'allow_resume': True}),
    Deployment(id='stable-diffusion-xl', model='stable-diffusion-xl', owner='organization-owner', object='deployment', status='succeeded', created_at=1724760524, updated_at=1724760524, scale_settings=ScaleSettings(scale_type='standard'), features={'rate': False, 'tokenize': False, 'truncate_prompt': False, 'configuration': False, 'system_prompt': True, 'tools': False, 'seed': False, 'url_attachments': False, 'folder_attachments': False, 'allow_resume': True}),
    Deployment(id='gemini-pro-vision', model='gemini-pro-vision', owner='organization-owner', object='deployment', status='succeeded', created_at=1724760524, updated_at=1724760524, scale_settings=ScaleSettings(scale_type='standard'), features={'rate': False, 'tokenize': False, 'truncate_prompt': False, 'configuration': False, 'system_prompt': True, 'tools': False, 'seed': False, 'url_attachments': False, 'folder_attachments': False, 'allow_resume': True}),
]

Make Completions Requests

client = Dial(api_key="your-api-key", base_url="https://your-dial-instance.com")

completion = client.chat.completions.create(
    deployment_name="gpt-35-turbo",
    stream=False,
    messages=[
        {
            "role": "system",
            "content": "2+3=",
        }
    ],
    api_version="2024-02-15-preview",
)

Asynchronous:

)

Working with Files

Working with URLs

Files are AI DIAL resources that operate with URL-like objects. Use pathlib.PurePosixPath or str to create to create new URL-like objects or to get a string representation of them.

• Use client.my_files_home() to upload a file into your bucket in the AI DIAL storage.
• Use await async_client.my_files_home() to get the URL of your bucket and then use it to upload files.

The following example demonstrates how you can use the path-like object returned by my_files_home() function:

sync_client.files.upload(
    url=sync_client.my_files_home() / "some-relative-path/my-file.txt", ...
)

async_client.files.upload(
    url=await async_client.my_files_home() / "some-relative-path/my-file.txt", ...
)

If you already have a relative URL like files/..., you can use it as well:

relative_url = "files/test-bucket/some-relative-path/my-file.txt"
sync_client.files.upload(url=relative_url, ...)

You can also use an absolute URL:

absolute_url = "http://dial.core/v1/files/test-bucket/some-relative-path/my-file.txt"
sync_client.files.upload(url=absolute_url, ...)

Note, that an invalid URL provided to the function, will raise an InvalidDialURLException exception.

Uploading Files

Use upload() to add files into your storage bucket:

with open("./some-local-file.txt", "rb") as file:
    # Sync client
    sync_client.files.upload(
        url=sync_client.my_files_home() / "some-relative-path/my-file.txt", file=file
    )
    # Async client
    await async_client.files.upload(
        url=await async_client.my_files_home() / "some-relative-path/my-file.txt",
        file=file,
    )

Files can contain raw bytes or file-like objects. To specify filename and content type of the uploaded file, use tuple instead of file object:

sync_client.files.upload(
    url=sync_client.my_files_home() / "some-relative-path/my-file.txt",
    file=("filename.txt", "text/plain", file),
)

Downloading Files

Use download() to download files from your storage bucket:

result = client.files.download(
    url=client.my_files_home() / "relative_folder/my-file.txt"
)

result = await async_client.files.download(
    url=await async_client.my_files_home() / "relative_folder/my-file.txt"
)

As a result, you will receive an object of type FileDownloadResponse, that you can iterate by byte chunks:

for bytes_chunk in result:
    ...

or get full content as bytes:

# Sync
all_content = result.get_content()
# Async
all_content = await result.aget_content()

or write it to the file:

# Sync
result.write_to("./some-local-file.txt")
# Async
await result.awrite_to("./some-local-file.txt")

Deleting Files

Use delete() to remove files from your storage bucket:

await sync_client.files.delete(
    url=sync_client.my_files_home() / "relative_folder/my-file.txt"
)

await async_client.files.delete(
    url=await async_client.my_files_home() / "relative_folder/my-file.txt"
)

Accessing Metadata

Use metadata() to access metadata of a file:

metadata = await async_client.files.metadata(
    url=await async_client.my_files_home() / "relative_folder/my-file.txt"
)

Example of metadata:

FileMetadata(
    name="my-file.txt",
    parent_path="relative_folder",
    bucket="my-bucket",
    url="files/my-bucket/test-folder-artifacts/test-file",
    node_type="ITEM",
    resource_type="FILE",
    content_length=12,
    content_type="application/octet-stream",
    items=None,
    updatedAt=1724836248936,
    etag="9749fad13d6e7092a6337c4af9d83764",
    createdAt=1724836229736,
)

Applications

List Applications

To get a list of your DIAL applications:

# Sync
applications = client.application.list()
# Async
applications = await async_client.application.list()

As a result, you will receive a list of Application objects:

[
    Application(
        object="application",
        id="app_id",
        description="",
        application="app_id",
        display_name="app with attachments",
        display_version="0.0.0",
        icon_url="...",
        reference="...",
        owner="organization-owner",
        status="succeeded",
        created_at=1672534800,
        updated_at=1672534800,
        features=Features(
            rate=False,
            tokenize=False,
            truncate_prompt=False,
            configuration=False,
            system_prompt=True,
            tools=False,
            seed=False,
            url_attachments=False,
            folder_attachments=False,
            allow_resume=True,
        ),
        input_attachment_types=["image/png", "text/txt", "image/jpeg"],
        defaults={},
        max_input_attachments=0,
        description_keywords=[],
    ),
    ...,
]

Get Application by Id

You can get your DIAL applications by their Ids:

# Sync
application = client.application.get("app_id")
# Async
application = await async_client.application.get("app_id")

As a result, you will receive a list of Application objects. Refer to the previous example.

Client Pool

When you need to create multiple DIAL clients and wish to enhance performance by reusing the HTTP connection for the same DIAL instance, consider using synchronous and asynchronous client pools.

Synchronous Client Pool

from aidial_client import DialClientPool

client_pool = DialClientPool()

first_client = client_pool.create_client(
    base_url="https://your-dial-instance.com", api_key="your-api-key"
)

second_client = client_pool.create_client(
    base_url="https://your-dial-instance.com", bearer_token="your-bearer-token"
)

Asynchronous Client Pool

from dial_client import (
    AsyncDialClientPool,
)

client_pool = AsyncDialClientPool()

first_client = client_pool.create_client(
    base_url="https://your-dial-instance.com", api_key="your-api-key"
)

second_client = client_pool.create_client(
    base_url="https://your-dial-instance.com", bearer_token="your-bearer-token"
)
