Ben Hylak
Co-founder and CTO of Raindrop, an AI agent monitoring and observability company building tools to detect, track, and fix failures in production AI agents. He previously worked in human interface design at Apple and has publicly spoken about Raindrop usage, case studies, experiments, and integrations for AI-agent reliability.
Agent Evals Must Raise the Floor, Not Chase the Ceiling
Ben Hylak of Raindrop argues that agent teams should focus less on headline capabilities than on raising the “floor”: the product-specific failures that break trust when agents can act through tools, permissions and external systems. Because agents can produce effectively unlimited issues, he says teams need to know when a failure began and what share of users it affects, then evaluate the full harness in code rather than rely on brittle chatbot-era test suites.
Cerebras IPO Puts a Public Price on Fast AI Inference
TBPN’s John Coogan and Jordi Hays use Cerebras’s first day as a public company to frame a narrower AI hardware argument: the market is beginning to price low-latency inference as a product in its own right. Cerebras founder Andrew Feldman argues that fast inference will eventually consume demand for slow AI responses, while SemiAnalysis’s Doug O’Laughlin cautions that the company’s wafer-scale SRAM architecture may be limited by memory scaling and model size. The result is a public-market test of whether owning a valuable slice of the AI compute stack is enough.
Production Agents Need Semantic Observability Beyond Offline Evals
Raindrop’s workshop argues that production agents need a different observability model from conventional software monitoring or offline evals. Zubin Kumar, Danny Gollapalli and Ben Hylak make the case that teams should track both explicit telemetry such as tool errors, latency and cost, and implicit signals such as user frustration, refusals, task failure, capability gaps and unusual workarounds. Their framework treats real production behavior as the primary surface for finding regressions, running experiments and catching failures that do not appear as clean exceptions.
