Meet ChatGPT-6 Astra: A Supercomputer for Only $20?

Share:
On September 3 OpenAI launched ChatGPT 6 Astra, reporting large gains versus prior models on multi-step tasks (41.4% vs 18.1%), advanced coding (74.1%), scientific work (64.6%) and extremely difficult maths (97.6%), and is rolling Astra to enterprise and cybersecurity customers with standard Astra included for $20/month ChatGPT Plus. OpenAI says Astra is the first model to meet its “critical” cybersecurity threshold and Astra Pro is reserved for Pro/Business/Enterprise, but it stopped short of declaring AGI and acknowledged top ARC-AGI-3 results used agent tooling and memory, so independent testing and implications for crypto, DeFi, CEX security and adoption remain to be validated.
In Brief
- OpenAI launched GPT-6 Astra on September 3, calling it its most capable ChatGPT model yet.
- Astra is strongest at multi-step computer tasks, advanced coding, scientific work, difficult maths, and using software with less human supervision.
- ChatGPT Plus users paying $20 a month are set to get standard Astra access.
Have you heard of AGI? Artificial General Intelligence. It’s the idea that AI can handle cognitive work at a human level. For years, it was just hypothetical, a Hollywood movie concept at best. Now, OpenAI says they have achieved it – with ChatGPT 6 Astra.
In theory, an AGI could read a legal document, write an article, solve a maths problem, plan a trip, learn a new software tool, and explain its reasoning – all at the same time. OpenAI just showed this exact thing in a ChatGPT 6 demo video.
In plain English, Astra is designed to do more than answer questions. It can use a computer, browse websites, work across software, and keep going through long tasks with less hand-holding.

How Powerful is ChatGPT 6.0 Astra?
OpenAI’s own benchmarks show the biggest gains in areas where AI has traditionally struggled: acting on its own.
| What is being tested? | GPT-6 Astra | GPT-5.6 Sol | Claude Fable 5.1 |
| Completing multi-step tasks | 41.4% | 18.1% | 31.4% |
| Advanced coding | 74.1% | 70.8% | 67.4% |
| Scientific computer work | 64.6% | 22.4% | 52.6% |
| Extremely difficult maths | 97.6% | 83.0% | 87.8% |
| Turning images into 3D designs | 95.9% | 83.3% | 84.3% |
The comparisons come from OpenAI and vendor-reported evaluations, so independent testing will matter.
So if you’re a ChatGPT user, what does this new model provide? Astra should be better at actually doing things for you.
OpenAI says it can browse webpages, fill forms, work through spreadsheets, and complete multi-step tasks faster than earlier models. It is also the first OpenAI model to reach the company’s “critical” cybersecurity threshold.
What are ChatGPT Users Getting for $20?
Astra is rolling out first to selected enterprise and cybersecurity customers. OpenAI says Plus, Pro, Business and Enterprise users will receive it over the coming days. Free access has not been announced.
That makes the $20-a-month ChatGPT Plus plan more interesting. Standard Astra will be included within existing Plus allowances.
Astra Pro, the higher-end version, is reserved for Pro, Business and Enterprise customers.
Does that make Astra AGI? OpenAI has stopped short of a formal declaration.

OpenAI president Brockman called AGI a “gray, fuzzy thing,” while saying he personally believes people may later look back at this model as the moment it arrived.
There is still reason for skepticism. Astra’s eye-catching ARC-AGI-3 result was produced using an OpenAI agent setup with memory and tools around the model, making it harder to isolate Astra’s raw intelligence from the system supporting it.
So, is this the end of human creativity? Perhaps not. But Astra does push ChatGPT further toward something that can increasingly do the work, rather than simply tell you how.
