A new study by Together AI has revealed the importance of diversity in AI by comparing two cutting-edge models, DeepSeek V4 Pro 0813 and Claude Fable 5, on the DeepSWE benchmark. The study highlights the strengths and weaknesses of each model, emphasizing the importance of diversity in AI and the need for a more diverse set of models to achieve better results. With a 90x lower cost per rollout compared to Fable 5, DeepSeek V4 Pro 0813 emerged as the stronger value pick for high-volume or retry-tolerant agent work. The study's findings have significant implications for the AI community, highlighting the importance of diversity and exploration in achieving better results.
Diversity in AI is crucial for achieving better results, as different models can complement each other. A study pitted two cutting-edge models, DeepSeek V4 Pro 0813 and Claude Fable 5, against each other in the DeepSWE benchmark. The results showed that DeepSeek V4 Pro 0813 outperformed Claude Fable 5 in terms of cost, accuracy, and failure modes. A diverse set of models, like DeepSeek V4 Pro 0813 and Fable 5, is essential for high-volume or retry-tolerant agent work. Routing between different models can achieve better results, as demonstrated by the study's findings.
In a groundbreaking study, the team behind Together AI has shed light on the importance of diversity in AI by pitting two cutting-edge models, DeepSeek V4 Pro 0813 and Claude Fable 5, against each other in the DeepSWE benchmark. This comprehensive analysis not only highlights the strengths and weaknesses of each model but also provides a deeper understanding of the value of diversity in AI, where different models can complement each other to achieve better results.
The DeepSWE benchmark is a software engineering ability test that evaluates a model's performance across various task types and programming languages. The study involved running both models on all 113 DeepSWE tasks, four trials each, resulting in a total of 904 rollouts. The results of this exhaustive test provide a detailed comparison of the two models, revealing their strengths and weaknesses in terms of accuracy, cost, and failure modes.
DeepSeek V4 Pro 0813 emerged as the stronger value pick for high-volume or retry-tolerant agent work, with a 90x lower cost per rollout compared to Claude Fable 5. The model's performance on pass@2 and pass@4 was particularly impressive, with 88.5% and 88.5% accuracy, respectively, while Fable alone achieved 69.7% and 84.1% accuracy. Moreover, DeepSeek V4 Pro 0813 returned 260 solves per $100, significantly outperforming Fable's 3 solves per $100.
Despite its lower cost, Fable 5 excelled in specific domains, such as data modeling and serialization, and languages like Rust. However, its failure modes were more pronounced, with a larger big-miss share of 18% compared to DeepSeek V4 Pro 0813's 10%. The study's authors argue that this highlights the importance of using a diverse set of models to achieve better results, rather than relying on a single model that may excel in specific areas but struggle in others.
The study's findings also shed light on the value of routing between different models. By running DeepSeek V4 Pro 0813 first and escalating to Fable 5 only when the test suite rejects the output, the authors achieved a 82.7% accuracy rate at $8.28 per task, significantly outperforming Fable alone and a perfect one-shot oracle router.
The authors conclude that the diversity of models is a key factor in achieving better results in AI, where different models can complement each other to achieve better results. They emphasize the importance of using a diverse set of models, such as DeepSeek V4 Pro 0813 and Claude Fable 5, to achieve better results in high-volume or retry-tolerant agent work.
The study's results have significant implications for the AI community, highlighting the importance of diversity in AI and the need for a more diverse set of models. As the AI landscape continues to evolve, it is essential that researchers and developers prioritize diversity and exploration, using a range of models to achieve better results.
In conclusion, the study on DeepSeek V4 Pro 0813 and Claude Fable 5 on DeepSWE provides valuable insights into the importance of diversity in AI and the value of complementarity between different models. By shedding light on the strengths and weaknesses of these two models, the study highlights the need for a more diverse set of models to achieve better results in AI.
