ClawBench is a browser agent evaluation framework built around 153 real-world tasks running on 144 live production websites — not simulated environments or curated sandboxes. Tasks span e-commerce, travel booking, SaaS dashboards, government portals, and developer tools. A built-in request interceptor blocks genuinely irreversible actions (payments, form submissions that send data) so evaluations can run safely on real sites. The benchmark records five layers of data per run: session replays, screenshots at each decision point, raw HTTP traffic, agent reasoning traces, and browser action sequences. This makes failure analysis tractable — you can see exactly which DOM element the agent misidentified, not just a final score. The dataset is open and the evaluation harness is reproducible. The headline finding is sobering: Claude Sonnet 4.6, the best performer, completes only 33.3% of tasks. GLM-5 is second at 24.2%. No model exceeds 50% on any individual task category. The implication is stark — current browser agents are far from autonomous on the open web, and the gap between benchmark performance and production performance is still enormous.

ORAC-NT
MedChem copilot that blocks toxic molecular modifications before you make them

ORAC-NT is an open-source medicinal chemistry copilot for early-stage drug discovery. Unlike general-purpose AI tools, it actively blocks synthetically infeasible or toxic molecular modifications — it won't just suggest them — and explains exactly why each transformation is rejected before proposing valid alternatives. The tool provides guided transformation pathways for common medicinal chemistry operations: halogenation, methylation, scaffold simplification, bioisosteric replacement, and solubility optimization. Each step generates an audit trail formatted for regulatory documentation, addressing a real gap in AI-assisted drug design where there's no clear chain of reasoning for a discovery team's choices. The target user is a medicinal chemist doing early lead optimization who wants AI assistance but can't afford hallucinated suggestions. ORAC-NT's guardrail-first design philosophy means it says 'no' often, with explanation — the opposite of most AI tools that optimize for appearing helpful.
Reviewer scorecard
“The five-layer recording (replays, HTTP traffic, reasoning traces) is the right approach for actual debugging — finally a benchmark where failure analysis is tractable. The 33% score also sets honest expectations for teams planning to ship production browser agents right now.”
“The regulatory audit trail feature alone makes this worth evaluating for any pharma team using AI. The FDA is going to want documentation on AI-assisted design decisions, and ORAC-NT is the only open-source tool I've seen that generates that output by design rather than as an afterthought.”
“Live website testing is a double-edged sword: sites change their DOM, anti-bot measures evolve, and a task that passes today may fail next week with no code change. Benchmark drift on live websites could make ClawBench scores meaningless over 6-month periods without constant maintenance.”
“Drug discovery is a domain where a wrong answer has real stakes, and 'open source with a paid cloud tier' is not how serious pharma teams procure safety-critical software. Until this has been validated against known drug series and peer-reviewed, treating it as anything other than a research prototype would be reckless.”
“33% on live websites is actually more impressive than it sounds given the adversarial diversity of the real web. The trajectory from 5% in 2024 to 33% in 2026 means we're likely crossing 60% in 18 months — at which point browser agents start displacing RPA software at scale.”
“AI in drug discovery has mostly been a hype layer on top of existing cheminformatics. ORAC-NT's approach — domain-specific guardrails, explainability, audit trails — is what responsible AI deployment actually looks like in high-stakes science. This design pattern will propagate to other regulated domains.”
“As someone who uses browser agents for research and competitor monitoring, the failure mode analysis is exactly what I need. Knowing which website categories agents handle well (dev tools) vs. poorly (government portals) helps me route tasks appropriately right now.”
“The UX philosophy here is fascinating from a design perspective: an AI tool that's deliberately more restrictive than helpful. That's a radical choice that goes against every growth metric. But in professional scientific contexts, trust comes from knowing the tool will say no to bad ideas. That's a design principle worth stealing.”
