Can AI Review Code Directly? The Changes and Cost Secrets Brought by GPT-6 Astra

Imagine this: Before you leave work, you tell your AI, “Review all the code I wrote today, fix the errors, and check for security issues,” and then you relax with a cup of coffee. If AI in the past was a tool for simply finishing sentences, we are now entering the era of ‘agents’ (software where AI autonomously sets goals and acts)—AI that can directly operate computers and perform complex tasks for you. At the center of this is OpenAI’s latest model, GPT-6 Astra.

Why is this important?

It is not just that performance has improved slightly. OpenAI’s Greg Brockman declared upon the release of GPT-6 Astra that “the era of AGI (Artificial General Intelligence) begins today” [Source: OpenAI Wows With The ‘AGI Era’ GPT-6 Astra… (https://wccftech.com/openai-wows-with-the-agi-era-gpt-6-astra-with-preliminary-benchmarks-showing-remarkable-performance-gains-as-sam-altman-says-releases-will-now-be-paced-by-safety-considerations-and-not-capabilit/)]. For the rest of us, this means AI is becoming a ‘competent assistant that actually completes the work I assign to it from start to finish.’ Especially in fields where mistakes are not tolerated, such as coding or security, the increasing utility of AI is a signal that the productivity of professionals could explode.

Understanding it simply

The core of GPT-6 Astra is a dramatic increase in its ‘ability to think and act.’ Put simply, AI no longer just answers questions—it now ponders how to solve problems on its own.

1. A Smart Strategist: In the difficult puzzle game ‘ARC-AGI-3’, Astra scored a whopping 98.6% [Source: OpenAI launches GPT-6 Astra… (https://thenewstack.io/openai-gpt6-astra-benchmarks/), Source: OpenAI’s GPT-6 Astra on ARC-AGI-3 (https://arcprize.org/blog/astra)]. To use an analogy, if typical AI was at the level of just reading a manual, Astra is like a strategist who predicts every move in a complex chess game in advance to find the best path.
2. The Magic of Efficiency: When performing complex tasks, Astra produces results with fewer ‘thoughts’ and ‘actions’ [Source: OpenAI’s GPT-6 Astra on ARC-AGI-3 (https://arcprize.org/blog/astra)]. For example, unlike previous models that had to transfer 10 times to get from Seoul to Busan, Astra reaches its destination with one high-speed train ride. Thanks to this, in high-difficulty tasks, there are cases where costs actually decrease [Source: OpenAI’s GPT-6 Astra on ARC-AGI-3 (https://arcprize.org/blog/astra)].
3. Intelligent Memory: It does not get lost even amidst long conversations or vast amounts of code. Through a device called ‘Responses API’ (a tool that helps the model remember previous flows of thought), it stacks thoughts step-by-step to reach optimal conclusions [Source: OpenAI launches GPT-6 Astra… (https://thenewstack.io/openai-gpt6-astra-benchmarks/)].

Current situation

Astra recorded 67 points on the Coding Agent Index (an indicator of how well AI performs coding tasks), surpassing the previous model ‘Sol’s’ 65 points [Source: GPT-6 Astra Review: The 37-Point Benchmark… (https://ofox.ai/blog/gpt-6-astra-review-2026/)]. It showed major improvements particularly in areas essential for actual development, such as computer use, cybersecurity, and terminal (command prompt) workflows [Source: GPT-6 Astra (Benchmarks Deep-dive)… (https://www.youtube.com/watch?v=qQzGm2-yVfM)].

However, there is a realistic barrier called ‘cost.’ Astra’s usage fee is $10 for input and $50 for output per million tokens, which is exactly twice as expensive as the previous model, GPT-5.6 Sol [Source: GPT-6 Astra API Pricing… (https://ofox.ai/blog/gpt-6-astra-api-pricing-2026/), Source: GPT-6 Astra: Complete Guide… (https://codersera.com/blog/gpt-6-astra-complete-guide-2026/)]. This presents a dilemma for companies: rather than deploying this powerful AI for every task, they must selectively use it for complex tasks that truly require efficiency.

What will happen next?

The future AI market will focus more on ‘how economically smart’ it is, rather than just ‘how smart’ it is. Astra is currently released in a limited capacity, and OpenAI is gradually expanding its release scope while prioritizing safety [Source: OpenAI Wows With The ‘AGI Era’ GPT-6 Astra… (https://wccftech.com/openai-wows-with-the-agi-era-gpt-6-astra-with-preliminary-benchmarks-showing-remarkable-performance-gains-as-sam-altman-says-releases-will-now-be-paced-by-safety-considerations-and-not-capabilit/)]. We ordinary users will witness more frequent scenes of AI directly reviewing code and plugging security holes, and it is expected that the cost of such high-performance AI will gradually decrease over time through technical optimization.

MindTickleBytes AI Reporter’s View

GPT-6 Astra is a milestone showing that AI is evolving from a ‘tool’ to a ‘colleague.’ Just as the cost of hiring an excellent professional is not small, we are now faced with the homework of how to more cleverly ‘employ’ AI. Technology continues to evolve, and ultimately, it is up to us humans to decide how to utilize that technology to maximize our life’s productivity.
