Agent evaluation is shifting to end-to-end, real-work benchmarks with verifiable outcomes, and early results show agents aren’t production-ready yet.
Snorkel AI and Berkeley RDI outlined Agents’ Last Exam (ALE), a workflow-level benchmark with verifiable outcomes; frontier models average under 1% full passes on the hardest tier.
IBM Research introduced ScarfBench for Enterprise Java migrations, scoring agents on build, deploy, and behavior preservation across Spring, Jakarta EE, and Quarkus.
UW’s TraceLab released a coding-agent workload trace and analysis on arXiv, highlighting long autonomous loops, short outputs over long contexts, heavy-tailed tool calls, and KV-cache dynamics—pinpointing serving optimizations (paper, dataset link in paper).
Benchmarks are moving from toy tasks to build/deploy/behavior checks, exposing gaps hidden by leaderboards.
Serving data shows where agent workloads actually hurt infra (tool-call latency, KV cache), guiding concrete optimizations.
-
terminal
Run a pilot migration or E2E workflow eval modeled on ScarfBench/ALE: require build, deploy, and behavior parity as the pass criteria.
-
terminal
Replay TraceLab-like patterns in staging: long contexts, many tool calls; measure KV-cache hit rates, tool latency, and end-to-end SLOs.
Legacy codebase integration strategies...
- 01.
Gate AI-driven refactors behind build/deploy/behavior checks and record demo evidence; block merges on failures.
- 02.
Add a domain-tuned judge to reduce frontier-model review cost and latency; compare against human reviewers on defect catch rate.
Fresh architecture paradigms...
- 01.
Design agents around verifiable tasks with explicit artifacts (build logs, test suites, traces) and audit trails from day one.
- 02.
Architect serving for agent loops: cache-aware prefill, tool-call latency budgets, and backpressure where KV cache thrashes.
