Quick Answer

GPT-6.1 Sol starts at $0.1345455 input / $0.6727275 output per million tokens on APIMaster, up to about 93.3% below OpenAI Standard. Open the Sol 6.1 model card, compare the available routes, and use the exact model ID gpt-6.1-sol.

Checked November 9, 2026 (UTC+8). All token prices are USD per million input / output tokens. Counts include enabled, non-exclusive public routes only. Ranges show paired prices from the lowest- and highest-input-priced routes. Current price and availability follow the live marketplace card.

Model ID	Original price	APIMaster current price	Active routes	Discount	Model card
`gpt-6.1-sol`	$2 / $10	From $0.1345455 / $0.6727275; range up to $0.4755616 / $2.377808	13	Up to about 93.3% off	Get Sol 6.1
`gpt-6.1-terra`	$1 / $5	From $0.1636877 / $0.8184385; range up to $1 / $5	2	Up to about 83.6% off	Compare Terra

Sol currently starts below Terra on this marketplace even though Sol has the higher official list price. That is a route-price observation, not a claim that Sol is always faster or better for every workload.

GPT-6.1 Sol pricing: OpenAI Standard vs Batch vs APIMaster

OpenAI's pricing page lists Sol 6.1 Standard short-context rates at $2 input / $10 output. The following comparison uses uncached tokens and at most 272K input tokens per request.

Access option	Input / output per 1M tokens	Conditions	Saving at APIMaster's lowest quote
APIMaster Sol 6.1	$0.1345455 / $0.6727275	Check the selected route's endpoints and billing terms	—
OpenAI Standard	$2 / $10	Synchronous, short context, uncached	About 93.3% lower token rates
OpenAI Batch / Flex	$1 / $5	Separate asynchronous / flexible processing terms	About 86.5% lower token rates

This compares token rates, not identical service contracts. OpenAI's cached input is **$0.10/M**, below APIMaster's displayed uncached input starting price. A cache-heavy workload must compare cache reads, writes and misses separately; a 93.3% uncached discount does not apply to every cached bill.

The official model documentation also specifies long-context surcharges above 272K input tokens, premium Fast/Ultrafast modes, and separately priced tools. Confirm how your selected route handles those features before a large run.

How much do coding and agent tasks cost?

Use input tokens × input rate / 1,000,000 + billed output tokens × output rate / 1,000,000. These are illustrative budgets, not measured benchmark results. Output includes billed reasoning where applicable.

Example token budget	OpenAI Standard	APIMaster from	APIMaster for 1,000 such tasks
10,000 input + 2,000 output	$0.04	$0.002691	$2.69
100,000 input + 20,000 output	$0.40	$0.026909	$26.91
Ten calls, each 100,000 input + 20,000 output	$4.00	$0.269091	$269.09

For the middle workload, 1,000 tasks cost about $26.91 instead of $400 before extras. An agent repeatedly sending a repository can multiply input usage: ten calls are ten bills, even when they belong to one user task. Cache, search, containers, retries and taxes are outside this table.

How to get a discounted Sol 6.1 API key

Open the live Sol card → register → fund your wallet → create an API key. Set API base https://apimaster.ai/v1 and model gpt-6.1-sol. A minimal text request is:

curl "https://apimaster.ai/v1/chat/completions" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-6.1-sol","messages":[{"role":"user","content":"Review this function for edge cases and propose a minimal fix."}]}'

For tool calling, OpenAI requires the Responses API. Use a route supporting that endpoint and follow the Codex setup guide for a coding client. This simple Chat Completions example does not configure tools or establish support for every official feature.

Which route should you choose?

Keep the exact model ID, then compare the required endpoint, streaming, tools, limits and recent route records. Try a small representative task before a long agent session. Behavioral fingerprint records provide identity evidence; they are not a guarantee that every request will succeed.

For the model's capabilities, see the Sol 6.1 overview. For adjacent buying decisions, compare cheap Claude Opus 4.8 and cheap Claude Sonnet 4.6. Different models can use different token counts to finish the same task.

FAQ

What is the cheapest GPT-6.1 Sol API price here?

The November 9 check found 13 public routes, starting at $0.1345455 input / $0.6727275 output per million tokens. Prices vary by route and can change; this is not an all-market lowest-price claim.

Is the 93.3% discount for both input and output?

Approximately, on the lowest quoted route compared with OpenAI's $2 / $10 Standard short-context uncached rates. Cache, tools, premium processing and long context require separate comparisons.

Does a ChatGPT subscription include this API balance?

No. ChatGPT and Codex subscription usage is separate from API token billing. An APIMaster wallet funds APIMaster API requests.

Can I use the same API key for other models?

Yes, for models and request profiles supported by your key and the available routes. Select the exact ID in the model card; changing models can change prices and supported features.
