The official OpenAI Python SDK v3.18.0 introduces new model identifiers for GPT-6 Sol and GPT-6 Luna, making these next-generation models addressable through the standard client APIs (chat, responses, etc.).

capability delta

An agent can now target OpenAI's GPT-6 Sol and Luna models via the openai-python SDK by passing the new model identifiers.

curator note

Release notes only mention adding GPT-6 Sol and Luna model identifiers; no API surface changes. Agent-relevant because it unlocks new models via the standard SDK.

// install
pip install openai==3.18.0

    input="Plan a 3-step research task on superconductors.",
)
print(resp.output_text)

# Or use the lighter Luna variant
resp = client.responses.create(
    model="gpt-6-luna",
