GPT 6.1 Sol Price: $2 Input, $10 Output per Million Tokens (API, Oct 2026)

GPT 6.1 Sol API price: $2 input and $10 output per million tokens, 1,050,000-token context. Price table, GPT-6 family comparison and OpenAI-compatible code.

Price data as of 2026-10-09. Base rates come from the BazaarLink model list; long-prompt rates follow OpenAI's announcement and pricing page. Actual BazaarLink billing follows the model page and your invoice.

GPT 6.1 Sol costs $2 per million input tokens and $10 per million output tokens, on the BazaarLink model list, with a 1,050,000-token context window. Per OpenAI's announcement, prompts longer than 272,000 tokens use the long-context rates of $4 input and $15 output. Prices are in US dollars.

GPT 6.1 Sol price table

Item (OpenAI list price)	Standard (prompt up to 272,000 tokens)	Long prompt (over 272,000 tokens)
Input, per million tokens	$2	$4
Output, per million tokens	$10	$15
Context window	1,050,000 tokens	same
Input types	text, image, file	same
Output type	text	same

The model id is openai/gpt-6.1-sol. BazaarLink bills at the list price with no markup. OpenAI's launch post and API pricing page list the tiered prices above and a cached-input price of $0.10 per million tokens. Actual BazaarLink billing follows the model page and your invoice.

How it compares with the rest of GPT-6

This compares published list prices only and says nothing about quality. Base rates (prompt up to 272,000 tokens) from the BazaarLink model list:

Model	Input / 1M	Output / 1M
GPT 6 Astra	$10	$50
GPT 6.1 Sol	$2	$10
GPT 6 Sol	$2	$10
GPT 5.6 Sol	$4	$20
GPT 6 Luna	$0.10	$0.50

OpenAI says 6.1 Sol comes close to Astra on some coding, computer-use and document benchmarks at one-fifth of Astra's standard input and output prices. Those results are the vendor's own, so run your own task before you decide. If your prompts often pass 272,000 tokens, budget with the long-prompt rates in OpenAI's announcement rather than the standard ones.

Estimating monthly cost

An illustrative calculation, not a benchmark: 1,000 requests a day, 10,000 input and 1,000 output tokens each, 30 days.

Input: 300M tokens x $2 = $600
Output: 30M tokens x $10 = $300
Total: about $900 a month, before caching discounts and retries

The same workload on GPT 6 Luna comes to about $45 and on GPT 6 Astra about $4,500. Test quality on your own task first, then compare the bills.

How to call it with the OpenAI SDK

Point base_url at BazaarLink and keep the key in an environment variable named BAZAARLINK_API_KEY, never in source.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://bazaarlink.ai/api/v1",
    api_key=os.environ["BAZAARLINK_API_KEY"],
)

resp = client.chat.completions.create(
    model="openai/gpt-6.1-sol",
    messages=[{"role": "user", "content": "Explain the TCP three-way handshake in three sentences."}],
)
print(resp.choices[0].message.content)

In Node.js, set baseURL to the same address, read process.env.BAZAARLINK_API_KEY, and pass openai/gpt-6.1-sol as the model. Parameters are listed on the model page.

Before you commit to a budget

A price table only gets you to a rough number. Four checks make the estimate much closer to what you will actually pay:

Measure real prompt length. OpenAI's announcement lists different rates above 272,000 tokens, which changes both rates, so look at the distribution of your prompt sizes, not just the average.
Read the usage field. Every response reports input and output token counts. Send a sample of 100 real requests, sum the usage, and multiply by the rates above.
Watch output volume. If you raise the reasoning effort, output tokens usually rise with it, and output is the more expensive side of the bill.
Test a cheaper tier on the same sample. Run GPT 6 Luna against the same 100 requests and compare answer quality as well as cost. If the cheaper model is good enough for part of your traffic, routing that part to it changes the monthly total far more than any discount on the larger one.

None of this needs code changes beyond the model id, because the endpoint stays the same.

FAQ

How much does the GPT 6.1 Sol API cost?

The BazaarLink model list (2026-10-09) shows $2 per million input tokens and $10 per million output tokens. Per OpenAI's announcement, prompts above 272,000 tokens are $4 input and $15 output. Actual BazaarLink billing follows the model page and your invoice.

What is the GPT 6.1 Sol context window?

1,050,000 tokens. It accepts text, image and file input and returns text.

Is GPT 6.1 Sol priced differently from GPT 6 Sol?

Not at the base rate. Both list at $2 input and $10 output. OpenAI's announcement points to a lower cached-input price for 6.1 Sol as the pricing change.
