## Summary

- **DeepSeek V4.1 Flash** has been benchmarked against top AI models like **GPT-6 Astra** and achieved an impressive score of 81.2 out of 100, matching nearly 99% of GPT-6 Astra's performance on real-world design tasks.

- Despite its superior performance, DeepSeek V4.1 Flash charges a mere $0.023 per finished design compared to **GPT-6 Astra**'s $1.61, making it nearly 7 times cheaper for the same level of output quality.

- Among 13 models tested, only GPT-6 Astra scored higher than DeepSeek V4.1 Flash on OpenDesign Arena's design benchmark. Other top performers like Claude Fable 5.1 and Qwen 3.8-Max cost more to run and perform worse in terms of output quality.

- **DeepSeek** has a strategy for scaling its success by recruiting engineers in Beijing to build their own Code Harness, aiming to control the entire AI stack rather than just the model itself.

## Key points

- DeepSeek V4.1 Flash outperforms GPT-6 Astra on design tasks
- Costs about 7 times less for similar performance
- Only GPT-6 Astra scores higher in terms of output quality

## Why it matters

This news highlights the potential of AI models to be both cost-effective and high-performing, which could significantly impact the design industry by lowering costs without compromising on quality.
