genblaze-replicate

Replicate provider adapter for genblaze — run any Replicate-hosted image, video, or audio model through a unified AI pipeline with SHA-256 provenance.

genblaze-replicate wraps Replicate's hosted model catalog (FLUX, SDXL, Stable Diffusion, video models, music models — anything on Replicate) as a genblaze provider. Compose Replicate calls into multi-step pipelines, persist outputs to Backblaze B2 or any S3-compatible store, and emit a tamper-evident provenance manifest for every run.

Why genblaze-replicate

• Any Replicate model, one API — Pass the owner/model slug; genblaze handles submission, polling, asset download, and manifest capture.
• Provenance by default — SHA-256 hash of every output, canonical manifest with prompt + params + timestamps.
• Composable — Chain Replicate outputs into downstream steps (image → video, upscale, transcode).
• Production-ready — Timeouts, retries, moderation hooks, step caching, OpenTelemetry tracing.
• Durable storage — Drop the genblaze-s3 sink in for B2/S3/R2/MinIO persistence of assets + manifests.

Models

Supports any model hosted on Replicate — including:

• Image — black-forest-labs/flux-schnell, black-forest-labs/flux-dev, stability-ai/sdxl, stability-ai/stable-diffusion-3
• Video — text-to-video and image-to-video models on Replicate
• Audio — music and speech models on Replicate

Use the full owner/model slug from https://replicate.com/explore — official and community models alike. submit() runs each via the right Replicate endpoint: community models resolve to their latest published version (cached per-slug), official models run version-less. Pin an exact community version with owner/model:<version-hash>.

Install

pip install genblaze-replicate

Registers the replicate provider via entry points; genblaze-core discovers it automatically.

Quickstart — FLUX Schnell (text-to-image)

pip install genblaze-core genblaze-replicate
export REPLICATE_API_TOKEN="r8_..."

from genblaze_core import Modality, Pipeline
from genblaze_replicate import ReplicateProvider

run, manifest = (
    Pipeline("flux-demo")
    .step(
        ReplicateProvider(),
        model="black-forest-labs/flux-schnell",
        prompt="a photorealistic golden retriever puppy in a field of wildflowers, "
               "golden hour, shallow depth of field",
        modality=Modality.IMAGE,
        num_outputs=1,
        aspect_ratio="1:1",
    )
    .run()
)

print(run.steps[0].assets[0].url)
print(manifest.canonical_hash)
assert manifest.verify()

Quickstart — persist to Backblaze B2

pip install genblaze-core genblaze-replicate genblaze-s3
export REPLICATE_API_TOKEN="r8_..."
export B2_KEY_ID="..."  B2_APP_KEY="..."

from genblaze_core import KeyStrategy, ObjectStorageSink, Pipeline
from genblaze_replicate import ReplicateProvider
from genblaze_s3 import S3StorageBackend

storage = ObjectStorageSink(
    S3StorageBackend.for_backblaze("my-bucket"),
    key_strategy=KeyStrategy.CONTENT_ADDRESSABLE,
)

result = (
    Pipeline("flux-b2")
    .step(ReplicateProvider(), model="black-forest-labs/flux-schnell",
          prompt="cyberpunk tokyo street at night, neon reflections on wet pavement")
    .run(sink=storage, timeout=120)
)

print(result.run.steps[0].assets[0].url)   # durable B2 URL
