Product Design: GPT-6 Astra vs. Opus 5

A comparative test has been announced between GPT-6 Astra (OpenAI) and Opus 5 (Anthropic) for product design. Fable 5.1, although presented as Anthropic's most advanced model and more efficient in tokens than Fable 5, has been excluded due to its perceived high cost, its absence from the Claude Pro plan, and execution times that can be up to twice as long as those of other models, according to the author.

Fable 5.1 excluded for cost, access, and reported slowness

Fable 5.1 is excluded from the comparison due to its perceived very high cost for content creation. This model is not included in the Claude Pro subscription, which requires purchasing an additional token quota to use it. Furthermore, it is reported to be slow for everyday design tasks, potentially taking up to twice as long as other models for similar results.

The selected face-off: GPT-6 Astra and Opus 5

The announced test will focus on two AI models for product design: GPT-6 Astra from OpenAI and Opus 5 from Anthropic. This choice comes as the proliferation of AI models makes selection more challenging for this type of use, and the question of which model is best suited is presented as very common.

Reported positioning of Anthropic: advanced and more efficient in tokens

Fable 5.1 is presented as Anthropic's most advanced AI model to date, with excellent results on numerous tasks, including product design. It is also described as more efficient in terms of token count than its predecessor Fable 5, but these advantages were not enough to justify its inclusion in the announced comparison.
