Organizations are rushing to deploy autonomous AI agents without adequate evaluation frameworks. New research reveals the critical gaps in how we assess AI agent capabilities—and points toward practical solutions.
The Strategic Reality
The first comprehensive survey of AI agent evaluation methods reveals a troubling reality: we're deploying increasingly sophisticated autonomous systems faster than we can properly assess them.
Researchers from IBM Research, Yale, and Hebrew University analyzed evaluation methods across four critical dimensions and found significant gaps in safety assessments, cost-efficiency metrics, and diagnostic capabilities.
The strategic risk: Organizations are essentially flying blind when deploying AI agents, creating invisible competitive vulnerabilities and operational risks.
New "scenario testing" approaches offer practical solutions for teams ready to deploy agents responsibly, creating competitive advantages in reliability and development velocity.
Flying Blind with Autonomous Systems
AI agents have evolved rapidly from simple chatbots to autonomous systems that plan multi-step strategies, use external tools, and maintain long-term memory. These systems can browse websites, write code, manage regulatory submissions, and coordinate with other agents to complete complex drug development workflows.
But here's the concerning reality: our ability to evaluate these agents hasn't kept pace with their capabilities.
The Business Exposure is Real
Invisible regressions plague development teams. A seemingly minor prompt change to improve one interaction can break five others, with failures only surfacing through frustrated stakeholders or incomplete regulatory responses.
Scale impossibility compounds the challenge. Testing a simple 5-turn conversation with 10 possible user responses at each turn creates 100,000 potential paths.
"When an AI agent encounters this healthcare provider inquiry: 'Before I prescribe this for my diabetic patient, I need to understand the contraindications with metformin, but first can you explain why the Phase III trial excluded patients over 65?' — has anyone tested that specific scenario?"
Without systematic testing, these complex multi-part inquiries only surface in production, often through frustrated healthcare providers or—worse—incomplete responses that compromise patient care decisions.
What the Research Reveals
The comprehensive survey analyzed evaluation methods across four critical dimensions:
Fundamental capabilities — planning, tool use, self-reflection, memory
Application-specific benchmarks — web agents, coding assistants, scientific agents
Generalist agent assessments — cross-domain performance
Evaluation frameworks — development and deployment tools
Three Critical Gaps Leaders Should Know
The research reveals troubling blind spots in current evaluation approaches:
Missing safety assessments: Current benchmarks lack comprehensive tests for robustness against adversarial inputs, bias mitigation, and organizational policy compliance.
Traditional evaluation methods weren't designed for systems that can autonomously access databases, generate clinical trial protocols, or interact with regulatory systems.
No cost-efficiency metrics: Most evaluations ignore the economic reality of agent operations—token usage, API expenses, inference time, and overall resource consumption.
Without understanding operational costs, organizations can't make informed decisions about when and where to deploy agents.
Limited diagnostic capabilities: We lack fine-grained diagnostic tools that can pinpoint exactly where and why agents fail.
When an agent produces an incomplete drug interaction analysis, current tools can't tell you whether the failure occurred in data retrieval, medical reasoning, or response generation.
The Evolution Toward Realistic Testing
The research reveals a clear trend: moving from static, simplified tests to dynamic, real-world evaluations that continuously update to match agent improvements.
Platforms like the Berkeley Function Calling Leaderboard have progressed through multiple versions, incorporating live datasets and multi-turn evaluation logic to remain relevant.
Why Traditional Testing Misses the Mark
Think about testing a laboratory information management system (LIMS). You input a sample ID, run an assay protocol, and verify you get the expected results format. This works because the system follows predictable rules: same input, same output, every time.
AI agents operate fundamentally differently.
Consider testing a medical affairs agent that responds to healthcare provider inquiries about drug interactions. The same concerned physician asking about the same drug combination might:
Frame the question differently each time ("Is this safe with diabetes medications?" vs. "What are the contraindications with metformin?" vs. "Should I worry about drug interactions?")
Need different levels of technical detail based on their specialty and experience
Require the agent to access different data sources (clinical trial data, prescribing information, post-market surveillance reports)
Follow entirely different conversation paths to get the safety information they need for their specific patient
The core challenge: Traditional testing assumes predictable behavior, but effective AI agents are designed to be adaptive, conversational, and context-aware. Testing them like traditional software misses the very capabilities that make them valuable.
The Breakthrough: Let AI Agents Test Each Other
LangWatch recognized a fundamental insight: if the best way to build conversational AI is with other AI, then the best way to test conversational AI is also with other AI.
Their "scenario testing" approach transforms evaluation:
How Scenario Testing Works
The Setup: Define a business scenario like "physician inquiring about drug interactions for a complex patient case"
The Participants: One AI agent acts as a realistic healthcare provider, another is your medical affairs agent being tested
The Interaction: They have an actual conversation, with the physician agent creating realistic clinical challenges, follow-up questions, and edge cases
The Assessment: The conversation continues until the medical inquiry is resolved or fails, giving you a complete picture of how your agent performs
This isn't just about checking if your agent gives the right final answer—it's about understanding how it handles the complex, nuanced nature of real healthcare provider interactions.
The Complete Testing Strategy
The most effective organizations combine scenario testing with traditional evaluation methods to create comprehensive confidence in their AI systems.
Level 1: Foundation Testing
Traditional software tests that verify the basic infrastructure works—your databases respond, your APIs function, your tools integrate properly. This is table stakes.
Level 2: Component Optimization
Focused testing of individual AI capabilities—ensuring your document retrieval finds the right clinical information, your response generation stays compliant with regulatory requirements, your classification systems work accurately. This optimizes the parts.
Level 3: Real-World Simulation
Scenario testing that validates how all these components work together in actual medical affairs conversations. This proves the whole system delivers the intended business outcomes.
Think of it like testing a new drug: Level 1 ensures the compound is stable, Level 2 optimizes dosing and delivery, Level 3 simulates real clinical conditions with diverse patient populations and comorbidities. You need all three to confidently bring the treatment to market.
Strategic Implications for Biotech Leaders
The Immediate Risks of Poor Evaluation
Organizations that deploy AI agents without proper evaluation face mounting risks:
Technical debt accumulation slows innovation. Teams stop modifying agents due to unpredictable behavior, hampering competitive response in fast-moving therapeutic areas.
Stakeholder experience degradation damages critical relationships. Undetected failures surface in interactions with healthcare providers, investigators, or regulatory agencies.
Competitive disadvantage emerges through slower iteration cycles compared to organizations with proper evaluation frameworks.
The Competitive Advantages of Robust Evaluation
Organizations that master AI agent evaluation gain significant strategic advantages:
Faster, safer iteration: Scenario testing eliminates the tedious back-and-forth of manual testing, allowing teams to confidently modify and improve agents.
Risk mitigation through understanding failure modes before deployment prevents costly incidents in regulated environments.
Quality scaling enables continuous improvement. Teams can change agent prompts, tools and structure while preventing regressions.
Five Strategic Takeaways
1. The evaluation gap is a strategic vulnerability — organizations deploying agents faster than they can evaluate them face invisible risks in regulated industries
2. Traditional testing approaches don't work — AI agents require new evaluation paradigms designed for non-deterministic, conversational systems
3. Practical solutions exist now — scenario testing frameworks offer production-ready approaches for responsible agent deployment
4. Cross-functional collaboration is essential — effective agent evaluation requires input from clinical, regulatory, technical, and commercial teams
5. Early investment in evaluation capabilities creates competitive advantage — organizations that master this will iterate faster and deploy more reliable systems
The Defining Moment for Biotech Leadership
We're witnessing a fundamental shift in what it means to be responsible technology leaders in life sciences. For decades, the industry has operated under rigorous validation standards for clinical trials and manufacturing, but applied looser standards to software systems.
That paradigm is catastrophically inadequate for autonomous AI agents that can access patient data, generate clinical protocols, or interact with regulatory systems.
The leaders who recognize this inflection point and invest in evaluation capabilities now aren't just avoiding risk—they're defining a new standard for AI deployment that will separate the winners from the casualties in the AI-driven future of drug development.
They understand that in a world where everyone has access to powerful language models, competitive advantage comes not from the raw capability of your AI, but from your ability to deploy it reliably, iterate confidently, and scale safely in regulated environments.
The research is clear: we have the tools to solve this challenge. Scenario testing frameworks and similar approaches prove that practical, production-ready evaluation methods exist today.
The question isn't whether we can build better evaluation—it's whether leaders have the foresight to prioritize it before their next regulatory interaction makes the choice for them.
The organizations mastering agent evaluation today will be the ones confidently scaling AI across drug development tomorrow, while their competitors are still debugging production failures and wondering why their AI initiatives consistently fall short of transforming their R&D productivity.
