REPLICATE_API_TOKENModel ID
openai/gpt-oss-120bReplicate 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
# openai/gpt-oss-120b format: "owner/model-name" (latest version) or "owner/model-name:version-hash"
output = replicate.run(
"openai/gpt-oss-120b",
input={"prompt": "Hello"}
