What gpt-5.6-sol costs
Provider prices per 1M tokens, updated August 24, 2026.moreless
These are the upstream provider rates. Pay as you go adds 5%, or 0% if you bring your own keys, and there is no per-request fee. Prompt caching and routing change what you pay against these rates, not the rates themselves.
This endpoint is discounted. List is $5.00 per 1M input and $30.00 per 1M output, and the rates below are what you pay. The discount applies to every request on this endpoint, with nothing to claim or enter.

Benchmarks measure the model, not this endpoint, so they are the same wherever these weights are served.
Artificial Analysis Coding Index: a composite of coding evaluations including LiveCodeBench, SciCode and Terminal-Bench.
Graduate-level physics, chemistry & biology questions designed to resist Googling.
Artificial Analysis Intelligence Index: a composite of multiple evaluations measuring overall model capability.

gpt-5.6-sol questions
How much does gpt-5.6-sol cost?
gpt-5.6-sol is priced at $4.50 per million input tokens and $27.00 per million output tokens when accessed via Requesty. Those figures include a 10% discount on this endpoint, off a list rate of $5.00 per million input tokens and $30.00 per million output tokens. Prompt caching is supported, which can cut effective input cost by up to 90% on repeated context. Those are the upstream provider rates: pay as you go adds 5% on top, or 0% if you bring your own provider keys.
What is the context window of gpt-5.6-sol?
gpt-5.6-sol has a context window of 1.1M tokens, with a maximum output of 128K tokens per response. That's roughly 1,400 words of input you can fit in a single prompt.
How does gpt-5.6-sol perform on benchmarks?
gpt-5.6-sol scores 94.1% on GPQA Diamond, 85.1% on τ²-Bench, 77.4% on Coding Index. See the full benchmark chart above for results across MMLU Pro, GPQA Diamond, SWE-Bench Verified, HumanEval, MATH, AIME, MMMU, and LiveBench.
What can gpt-5.6-sol do?
gpt-5.6-sol supports vision input, tool calling, extended reasoning, prompt caching, structured outputs (JSON schema). You can call it through any OpenAI-compatible client by pointing base_url to Requesty.
How do I use gpt-5.6-sol with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "azure/gpt-5.6-sol@eastus2". The Quickstart above shows Python, JavaScript and cURL snippets.
Can I run gpt-5.6-sol through Requesty?
Yes. gpt-5.6-sol runs through Requesty's OpenAI-compatible API, served from Microsoft Azure AI in eastus2. You do not host the model yourself: point base_url at Requesty, set the model to "azure/gpt-5.6-sol@eastus2", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
What region is this deployment?
This variant of gpt-5.6-sol is deployed in eastus2. Region-specific endpoints matter for data residency, latency to your users, and compliance requirements (GDPR, HIPAA). Other regions for the same model may be listed on the Microsoft Azure AI provider page.
