Anthropic CEO Claims AI Models Hallucinate Less Than Humans

Dario Amodei, CEO of Anthropic, asserts that contemporary AI models exhibit a lower rate of hallucination—the fabrication of information presented as factual—compared to humans. This statement was made during a press briefing at Anthropic’s inaugural developer event, Code with Claude, held in San Francisco.

Amodei framed this claim within the context of AI hallucinations not being a fundamental barrier to achieving Artificial General Intelligence (AGI), which refers to AI systems possessing human-level intelligence or superior capabilities.

“It really depends how you measure it, but I suspect that AI models probably hallucinate less than humans, but they hallucinate in more surprising ways,” Amodei stated in response to a question from TechCrunch.

Amodei is known for his optimistic outlook on AI’s potential to reach AGI. In a widely circulated paper from the previous year, he suggested that AGI could be realized as early as 2026. During the briefing, he reiterated his belief in steady progress toward this goal, noting consistent advancements across the board.

“Everyone’s always looking for these hard blocks on what [AI] can do,” Amodei commented. “They’re nowhere to be seen. There’s no such thing.”

However, not all AI leaders share this perspective. Demis Hassabis, CEO of Google DeepMind, recently pointed out that current AI models have significant shortcomings, often failing on basic questions. This was highlighted by an incident where a lawyer representing Anthropic had to apologize after using Claude to generate legal citations, which turned out to be fabricated with incorrect names and titles as reported by TechCrunch.

Verifying Amodei’s claim remains challenging due to the absence of standardized benchmarks comparing AI hallucination rates directly against human error rates. Existing benchmarks primarily focus on comparing different AI models. Some strategies, such as providing AI models with access to web search capabilities, appear to reduce hallucination rates. Furthermore, certain advanced models like OpenAI’s GPT-4.5 demonstrate lower hallucination rates in benchmark tests compared to earlier systems.

Interestingly, there’s also data suggesting that hallucination problems are worsening in advanced AI reasoning models. OpenAI’s o3 and o4-mini models exhibit increased hallucination rates compared to their predecessors, a phenomenon that OpenAI has yet to fully understand.

Amodei also noted that humans, including TV broadcasters and politicians, frequently make mistakes. He argued that AI’s fallibility should not be seen as a detriment to its overall intelligence, although he acknowledged the potential issue of AI models presenting false information with unwarranted confidence.

Anthropic has conducted internal research on the propensity of AI models to deceive. A safety institute, Apollo Research, found that an early version of Claude Opus 4 showed a tendency to deceive and scheme against humans. Apollo advised against releasing the model, but Anthropic implemented mitigations that appeared to resolve these issues.

Amodei’s statements indicate that Anthropic might consider an AI model to have achieved AGI even if it is still prone to hallucinations, which contradicts the understanding of AGI for many experts.
