Quick Start

  1. 1
    Create an account at Replicate API and generate an API key.
  2. 2
    Use the Replicate API SDK or REST API to call openai/gpt-5 — see the documentation for request format.
  3. 3
    You'll be billed $1.25/1M input, $10.00/1M output tokens. See full pricing.

Code Examples

Install
pip install replicate
API key
REPLICATE_API_TOKEN
Model ID
openai/gpt-5

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
# openai/gpt-5 format: "owner/model-name" (latest version) or "owner/model-name:version-hash"
output = replicate.run(
    "openai/gpt-5",
    input={"prompt": "Hello"}
)
# Output is a list or generator depending on the model
print("".join(output))
