The landscape of artificial intelligence is rapidly evolving, with AI laboratories increasingly turning to crowdsourced benchmarking platforms to assess the performance of their latest models. However, a growing number of experts are raising concerns about the validity and ethical implications of this approach.
Understanding the Rise of Crowdsourced Benchmarking
In recent years, major AI organizations have embraced platforms that utilize user participation to evaluate the capabilities of their models. These platforms often present a favorable score as a testament to advancements in AI technology. Yet, this method of evaluation is under scrutiny for its potential shortcomings.
Concerns from Experts
Emily Bender, a linguistics professor at the University of Washington, has voiced her concerns regarding the effectiveness of these benchmarking platforms. She argues that for a benchmark to be credible, it must measure specific constructs with clear validity. Bender points out that platforms like the one in question have not demonstrated a reliable correlation between user preferences and the outputs generated by different models.
Exaggerated Claims and Misleading Practices
Asmelash Teka Hadgu, co-founder of an AI company, believes that these benchmarking systems are often manipulated by AI labs to support inflated claims about their models. He cites a recent incident involving a well-known AI model that was fine-tuned to perform well on a benchmarking platform, only to have a less effective version released to the public.
The Need for Dynamic and Diverse Benchmarks
Hadgu advocates for a more dynamic approach to benchmarking, suggesting that evaluations should be conducted by independent entities across various sectors, including education and healthcare. This would ensure that benchmarks are tailored to specific applications and reflect the needs of professionals who utilize these models.
Compensation for Evaluators
Both Hadgu and Kristine Gloria, a former leader in technology initiatives, argue that individuals who evaluate AI models should be compensated for their contributions. They emphasize the importance of learning from past mistakes in the data labeling industry, which has faced criticism for exploitative practices.
Value of Crowdsourced Benchmarking
Despite the criticisms, Gloria acknowledges the potential benefits of crowdsourced benchmarking, likening it to citizen science initiatives that enrich the evaluation process. However, she cautions that these benchmarks should not be the sole metric for assessing AI models, as they can quickly become outdated in a fast-paced industry.
Internal Evaluations and Transparency
Matt Fredrikson, CEO of a company specializing in crowdsourced evaluations, notes that while volunteers are motivated by various factors, public benchmarks cannot replace comprehensive internal assessments. He stresses the importance of clear communication regarding evaluation results and responsiveness to inquiries.
Broader Perspectives on Benchmarking
Industry leaders, including those from model marketplaces, agree that relying solely on open testing and benchmarking is insufficient. They advocate for a multifaceted approach that incorporates various testing methods to ensure a comprehensive understanding of model performance.
Commitment to Fair Evaluations
In response to recent discrepancies in benchmarking results, representatives from the benchmarking platform have taken steps to enhance their policies, aiming to ensure fair and reproducible evaluations. They emphasize their commitment to providing a transparent environment for users to engage with AI and contribute feedback.
In conclusion, while crowdsourced benchmarking offers valuable insights into AI model performance, it is essential to address the concerns raised by experts to ensure that these evaluations are both ethical and reliable. A balanced approach that incorporates diverse perspectives and compensates evaluators may pave the way for more accurate assessments in the future.
