OpenAI: GPT-6 Astra Pro

openai/gpt-6-astra-pro

Our take

AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.

OpenRouter's catalog lists openai/gpt-6-astra-pro as an OpenAI model that accepts text, image, and file inputs and returns text. The catalog describes it as the same underlying model as GPT-6 Astra, served in a pro reasoning mode intended for higher-quality responses on complex tasks. Reasoning is mandatory, with medium as the default effort and several selectable levels. The listing reports a 1,050,000-token context window and support for tools and structured outputs. No independent model card or benchmark results were available in this source pack.[1]

Strengths

Catalog-reported support for text, image, and file inputs with text output.[1]
Mandatory reasoning with a medium default effort and multiple selectable levels.[1]
Catalog-reported 1,050,000-token context window plus tool and structured-output support.[1]

Limitations

Only OpenRouter catalog evidence was supplied; an independent model card was not available in this source pack.[1]
The supplied catalog data contains no benchmark entries, so measured performance remains unverified here.[1]
A truncated cost note indicates substantially higher spending in pro mode, but the supplied text lacks the details.[1]

Where to use it

Consider for complex reasoning tasks where configurable, always-on reasoning is desirable.[1]
Potentially useful for workflows that combine text, image, and file inputs and require text output.[1]
May fit applications that need tool calling or structured text outputs.[1]

About this model

Description below is the original text supplied by OpenRouter, shown in the source language.

GPT-6 Astra Pro is the same underlying model as [GPT-6 Astra](https://openrouter.ai/openai/gpt-6-astra), served with `reasoning.mode` set to `pro` for higher-quality responses on complex tasks. **Cost note:** pro mode spends far more...

Tasks and capabilities

A grade appears only where the source supplies a matching measurement for that task, the model is active and the cohort holds at least 10 comparable models. The capability column lists facts the source declares — supported formats, reasoning and tool parameters — which are not measured quality.

Task	Grade	Source-declared capability
General quality	No measurement	reasoning: mandatory · default medium · efforts: max, xhigh, high, medium, low · parameters: include_reasoning, reasoning, reasoning_effort

Writing	No measurement	output: text
Reasoning	No measurement	reasoning: mandatory · default medium · efforts: max, xhigh, high, medium, low · parameters: include_reasoning, reasoning, reasoning_effort

How grades work

Each letter grade compares a model only against other models scored by the same source and metric in the current snapshot. S means the top 10%, A the next 20%, B the next 30%, C the rest. Models without a published measurement are shown as not rated — a supported format alone never implies measured quality.

S — S — top 10% of the cohort
A — A — next 20% of the cohort
B — B — next 30% of the cohort
C — C — below the B band
