Code Examples
pip install replicateREPLICATE_API_TOKENfalcon-40bReplicate 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
# falcon-40b format: "owner/model-name" (latest version) or "owner/model-name:version-hash"
output = replicate.run(
"falcon-40b",
input={"prompt": "Hello"}
)
# Output is a list or generator depending on the model
print("".join(output))Pricing on Replicate API
