1.1.0b1 Pre-release
Pre-release

What's Changed

The main change in 1.1.0b1 is the introduction of a new experimental replicate.use() function intended to eventually replace replicate.run(). This provides a more expressive function-like interface for calling models.

import replicate

flux_dev = replicate.use("black-forest-labs/flux-dev")
outputs = flux_dev(prompt="a cat wearing an amusing hat")

for output in outputs:
    print(output) # /tmp/output.webp

Check out the README.md on the beta branch for more details.

  • Switch to using uv for project tooling by @aron in #437
  • Add experimental replicate.use() function by @aron in #438

What's Changed

If you run replicate-python within a cog model running cog 0.14.11 or later, it is now possible to pass a REPLICATE_API_TOKEN via the context as part of a prediction request.

The Replicate() constructor will now use this context when available. This grants cog models the ability to use the Replicate client libraries, scoped to a user on a per request basis.

What's Changed

  • Fix two bugs in the base64 file_encoding_strategy by @aron in #398
    • replicate.run() now correctly converts the file provided into a valid base64 encoded data URL.
    • replicate.async_run() now respects the file_encoding_strategy flag.

Warning

Breaking changes

This 1.0.0 latest release of replicate contains breaking changes. The replicate.run() method will now return FileObjects rather than URL strings by default for models that output files.

The FileObject implements an iterable object similar to httpx.Response to make it easier to work with files and ensures that Replicate can deliver file data to the client in the most efficient manner possible.

For example:

[output] = replicate.run(
  "black-forest-labs/flux-schnell",
  input={"prompt": "astronaut riding a rocket like a horse"},
);

For most basic cases you'll want to utilize either the url or read() fields depending on whether you want to directly consume the file or pass it on.

To access the file URL:

print(output.url) #=> "https://delivery.replicate.com/..."

To consume the file directly:

with open('output.bin', 'wb') as file:
    file.write(output.read())

Or for very large files they can be streamed:

with open(file_path, 'wb') as file:
    for chunk in output:
        file.write(chunk)

Each of these methods has an equivalent asyncio API.

async with aiofiles.open(filename, 'w') as file:
    await file.write(await output.aread())

async with aiofiles.open(filename, 'w') as file:
    await for chunk in output:
        await file.write(chunk)

For streaming responses from common frameworks, all support taking Iterator types:

Django

@condition(etag_func=None)
def stream_response(request):
    output = replicate.run("black-forest-labs/flux-schnell", input={...}, use_file_output =True)
    return HttpResponse(output, content_type='image/webp')

FastAPI

@app.get("/")
async def main():
    output = replicate.run("black-forest-labs/flux-schnell", input={...}, use_file_output =True)
    return StreamingResponse(output)

Flask

@app.route('/stream')
def streamed_response():
    output = replicate.run("black-forest-labs/flux-schnell", input={...}, use_file_output =True)
    return app.response_class(stream_with_context(output))

In case of breakages, in most instances, updating existing applications to call output.url should fix issues.

To revert to previous behaviour you can opt out of FileOutput by passing use_file_output=False to the replicate.run() method.

const replicate = replicate.run("acmecorp/acme-model", use_file_output=False);
