Introduction: Why Test Two AI Models Simultaneously?
The past year has seen the arrival of two giants in natural language processing, Anthropic’s Fable 05.1 and OpenAI’s GPT‑6 Astra. Each model promises unprecedented performance, but theory alone isn’t enough – you need real-world tests to gauge their usefulness.
To do this, I chose to create a personal portfolio, a project that blends design, copywriting, and SEO optimisation. This task demands precision, creativity, and speed—exactly the qualities we expect from a modern AI model.
1. Model Overview: Fable 05.1 and GPT‑6 Astra
Fable 05.1 is Anthropic’s first public model, built on the same architecture as Mythos 05.1 but with enhanced safeguards for general use. It stands out for its robust contextual understanding and a tendency to avoid hallucinations.
GPT‑6 Astra, meanwhile, is OpenAI’s inaugural GPT‑6 model, touted for having a “better visual” capability for building websites and applications. Its ability to generate clean CSS/HTML code has been praised by developers.
2. Testing Methodology: The Same Prompt for Both
To ensure fairness, I crafted a detailed prompt describing my professional profile, skills, and desired sections (About, Projects, Contact). I then submitted this prompt to each model via their API interface.
The goal was to compare the quality of generated text, relevance of design suggestions, and execution speed. Each response was evaluated on a 1‑to‑5 scale for these criteria.
3. Results: Performance, Creativity, and Behaviour
Fable 05.1 achieved an overall score of 4.7/5. It produces highly coherent text, avoids frequent inconsistencies seen in some models, and offers SEO‑friendly catchy titles.
GPT‑6 Astra scored 4.3/5. Its responses are more dynamic, with a clear visual structure, but sometimes lack precision on requested technical details.
4. Detailed Analysis: Strengths and Weaknesses
Strengths of Fable 05.1
The AI excels at generating fluid narrative content with a tone tailored to a professional audience. It follows SEO guidelines without forcing the text.
Its ability to maintain context over multiple exchanges is remarkable, reducing the need to rewrite entire sections.
Strengths of GPT‑6 Astra
Astra automatically proposes a responsive page layout, including colour and typography suggestions, speeding up visual prototyping.
It also integrates ready‑to‑use code snippets (HTML/CSS), which is an asset for developers looking to move quickly from mockup to product.
5. Conclusion: Which Model Should You Choose for Your Portfolio?
If your priority is copywriting quality and organic search ranking, Fable 05.1 will be your best ally. Conversely, if you need a structured design and ready‑to‑use code, GPT‑6 Astra offers a clear advantage.
“The difference is immediate: Fable talks better, Astra builds faster.”
In conclusion, don’t hesitate to test both models on a small project before committing. You’ll be able to measure the real impact on your productivity and visitor satisfaction.
