OpenAI has released MentalHealthBench, an open-source benchmark designed to evaluate how AI models perform during mental health and emotional support conversations. The tool was developed in collaboration with more than 80 licensed psychologists and psychiatrists across 22 countries. It utilizes a dataset of synthetic conversations—covering non-acute stress, high-acuity situations, and emergencies—to test model behaviors such as clinical accuracy, empathy, and urgency . OpenAI reports that it uses its GPT-5.6 Sol model as an automated grader to score responses against expert-defined rubrics.
OpenAI's MentalHealthBench consists of synthetic conversations designed to simulate real-world patterns of AI use in mental health. The dataset includes scenarios involving adults, teenagers, caregivers, and clinicians, spanning 19 languages. The distribution of the benchmark is 53.5% non-acute, 18.2% high-acuity, and 28.3% emergency situations.
The evaluation methodology relies on rubrics created by mental health experts, where responses are scored from -10 to +10 based on clinical importance. Each conversation was reviewed by at least three experts, with criteria retained only upon consensus. OpenAI uses its GPT-5.6 Sol model to automate the grading of other models against these rubrics.
In initial testing, OpenAI reported that GPT-6 Astra achieved the highest score at 57.3%, followed by GPT-6 Sol (53.9%), Claude Opus 5.5 (52.4%), GPT-6 Luna (50.2%), and Muse Spark 1.3 (47%). Older models, including GPT-4o (32.1%) and Gemini 2.5 Pro (29.5%), scored significantly lower.
OpenAI conducted a supplemental study with 44 adults who had prior experience using AI for mental health. The study revealed a divergence in priorities: users prioritized tone and actionable steps, while clinicians prioritized context gathering and the interpretation of ambiguous information. OpenAI noted that these user preferences did not alter the benchmark's expert-derived scoring criteria.

为什么这很重要
As AI increasingly becomes a tool for emotional support, establishing standardized, clinically-informed evaluation methods is critical for safety. MentalHealthBench moves beyond simple harm avoidance by measuring nuanced clinical behaviors like context gathering and agency preservation. By providing an open framework, OpenAI allows researchers to compare model performance across a spectrum of mental health needs, highlighting significant performance gaps between newer models like GPT-6 Astra and older iterations like GPT-4o. This transparency is essential for understanding how AI systems navigate the complex, high-stakes domain of mental health, though OpenAI emphasizes that these scores are not measures of clinical effectiveness and that AI remains a supplement, not a replacement, for professional care.
The release of MentalHealthBench addresses a significant gap in : the lack of standardized, clinically-grounded evaluation for emotional support interactions. By moving the conversation beyond binary 'harm avoidance,' the benchmark forces a focus on the quality and accuracy of AI-provided guidance.
The project highlights the tension between clinical standards and user experience. The finding that users and clinicians value different aspects of a conversation underscores the difficulty of designing AI that is both safe and perceived as helpful by individuals in distress.
The benchmark provides a concrete, measurable way to track progress in AI's ability to handle sensitive, multi-turn conversations. As models continue to evolve, this tool serves as a baseline for assessing whether improvements in general reasoning translate into safer, more effective interactions in the mental health domain.

Researchers and developers can now access the MentalHealthBench dataset to conduct their own evaluations. A key area to monitor is how the industry adopts these specific metrics—such as 'urgency ' and 'clinical accuracy'—in future safety standards. Additionally, the discrepancy between clinician-weighted criteria and user-preferred traits (such as tone and practical steps) suggests that future iterations of benchmarks may need to reconcile expert clinical standards with real-world user expectations. It remains to be seen how other AI providers will respond to these benchmarks and whether they will adopt similar collaborative, expert-led evaluation frameworks.
Watch for whether other major AI labs adopt MentalHealthBench as a standard for their own safety reporting or if they develop competing benchmarks that prioritize different clinical or user-centric metrics.
Monitor the potential for 'benchmark gaming,' where models are specifically optimized to score well on these rubrics without necessarily improving the underlying quality of care or safety in real-world, unscripted interactions.
