Code Examples

Install
pip install replicate

Replicate uses "owner/model-name" format (e.g. "meta/meta-llama-3-8b-instruct") for the latest version, or "owner/model-name:version-sha" to pin to a specific version. The REST endpoint splits owner and model-name into the path: /v1/models/{owner}/{model-name}/predictions.

import replicate

# reads REPLICATE_API_TOKEN from env
# nous-hermes2-yi-34b format: "owner/model-name" (latest version) or "owner/model-name:version-hash"
output = replicate.run(
    "nous-hermes2-yi-34b",
    input={"prompt": "Hello"}
)
# Output is a list or generator depending on the model
print("".join(output))
