GPT-6.1 Sol API in Singapore

In Singapore dollars, the currency your card is charged in, with the published US dollar rate beside each.

For scale: 1,000 requests of about 3,000 tokens in and 1,000 out cost S$21.42 — a long prompt and a page of answer each. Every rate is published and stays the same from one request to the next. See every model.

Prices are our published US dollar rates converted at S$1.30 to the dollar, our rate for October — the same rate your card is charged.

GPT-6.1 Sol came out at OpenAI’s DevDay on 29 September 2026, a week after GPT-6 Sol and at the same price. OpenAI says it matches GPT-6 Astra on the DeepSWE coding test at about a fifth of the cost, and lands within about two points of Astra on OSWorld, the computer-use test, at roughly a seventh of the cost per task.

It is the GPT to pick for production agents that need to be both good and affordable: coding, operating software, building documents and spreadsheets. It always reasons a little — the lowest setting is low — and OpenAI says it makes a factual error in about a third fewer answers than GPT-6 Sol at that setting.

• Production coding agents at a mid-tier price.
• Operating software and working through web forms.
• Professional documents and spreadsheet work.
• Science and command-line work on a budget.

• Astra still leads on the hardest science problems.
• OpenAI’s cost comparisons are against Claude Opus 5.5; its like-for-like rival on price is Claude Sonnet 5.5, so compare against that.
• Released on 29 September 2026, so independent testing is still thin.

Roar AI provides access to GPT-6.1 Sol through the Roar AI gateway, charged in Singapore dollars on one bill with every other model. Requests from Singapore go through our gateway in Singapore. Developers can use GPT-6.1 Sol alongside other supported models without a separate integration for every provider.

Use the OpenAI SDK you already have — point it at Roar AI and name the model. Read the docs.

from openai import OpenAI

client = OpenAI(base_url="https://api.roar-ai.com/v1", api_key="roar_live_…")

reply = client.chat.completions.create(
    model="gpt-6.1-sol",
    messages=[{"role": "user", "content": "Summarise this contract in plain English."}],
)

GPT-6.1 Sol is a frontier model, and requests are processed on international infrastructure, outside Singapore. The model directory says where each model is processed.
