As AI reasoning models become more sophisticated, the expenses associated with benchmarking them are skyrocketing, raising questions about accessibility and transparency in AI development.
Artificial Intelligence (AI) is rapidly evolving, with new “reasoning” models claiming superior capabilities in complex problem-solving. These models, which can “think” through problems step by step, are being touted as the next big leap in AI. However, a hidden challenge is emerging: the skyrocketing costs of benchmarking these advanced systems. Is the industry heading towards a future where only a few players can afford to verify AI performance claims independently?
The High Price of Reasoning:
Benchmarking AI models involves evaluating their performance across a range of standardized tests. According to Artificial Analysis, a third-party AI testing firm, evaluating OpenAI’s o1 reasoning model across seven popular AI benchmarks costs approximately $2,767.05. In comparison, testing Anthropic’s Claude 3.7 Sonnet, a hybrid reasoning model, costs $1,485.35. Even “mini” versions of these models aren’t cheap, with OpenAI’s o3-mini-high costing $344.59 to benchmark.
George Cameron, co-founder of Artificial Analysis, notes that his organization has spent roughly $5,200 evaluating about a dozen reasoning models. This is nearly double the $2,400 spent analyzing over 80 non-reasoning models. To put this in perspective, benchmarking OpenAI’s non-reasoning GPT-4o model costs just $108.85, while Claude 3.6 Sonnet costs $81.41.
Examples and Statistics:
- OpenAI’s o1 Reasoning Model: $2,767.05 to evaluate
- Anthropic’s Claude 3.7 Sonnet: $1,485.35 to benchmark
- OpenAI’s GPT-4o (non-reasoning): $108.85 to evaluate
Why Are Reasoning Models So Expensive to Test?
The primary reason for the high cost is the number of tokens these models generate. Tokens are the basic units of text that AI models process. Reasoning models tend to produce significantly more tokens than their non-reasoning counterparts when tackling complex tasks.
For instance, OpenAI’s o1 generated over 44 million tokens during Artificial Analysis’s benchmarking tests, about eight times more than GPT-4o. Since most AI companies charge by the token, the costs can quickly add up.
Jean-Stanislas Denain, a senior researcher at Epoch AI, explains that modern benchmarks often involve complex, multi-step tasks that require models to write and execute code, browse the internet, and use computers. These tasks naturally elicit more tokens, driving up the overall cost.
The Reproducibility Crisis:
Ross Taylor, CEO of AI startup General Reasoning, highlights the growing concern over the reproducibility of AI benchmark results. He spent $580 evaluating Claude 3.7 Sonnet on around 3,700 unique prompts. Taylor estimates that a single run-through of MMLU Pro, a benchmark for language comprehension skills, would cost over $1,800.
Taylor points out that if AI labs report benchmark results based on compute resources that academics and independent researchers cannot afford, the results become difficult, if not impossible, to replicate. This raises serious questions about the scientific validity of these benchmarks.
The Role of AI Labs:
Many AI labs, including OpenAI, offer benchmarking organizations free or subsidized access to their models. While this might seem helpful, it introduces potential biases. Even without evidence of manipulation, the mere suggestion of an AI lab’s involvement can undermine the credibility of the evaluation process.
Taylor argues that if benchmark results cannot be replicated with the same model by independent parties, their scientific value is questionable.
The Future of AI Benchmarking
As AI reasoning models become more prevalent, the costs of benchmarking them are likely to continue rising. This trend poses a significant challenge to the AI community, potentially limiting independent verification of AI performance claims. To maintain transparency and trust, it’s crucial to address the rising costs of AI benchmarking and ensure that these evaluations remain accessible to a broad range of researchers and organizations. The future of AI depends on it.
