GPT-5.6 Sol · Community source · Platform telemetry

Lynkr ITSMBench: routing lowers cost while Sol's binary pass rate remains limited

Lynkr routed Sol through pi on 89 enterprise IT-service tasks: 31% full-suite Pass@1, 35%/40% matched Pass@1/Pass@2, about $0.87–$0.90 per task, and 92–95% cache hits; many failures missed only a few assertions.

Key data and applicable tasks

Summary

Lynkr published ITSMBench results obtained by calling GPT-5.6 Sol through pi: 89 enterprise IT service-desk tasks, Pass@1/Pass@2, cost, prompt-cache hit rate, and a breakdown by task family, along with a discussion of the limitations of binary scoring.

We put Lynkr through ITSMBench: 89 enterprise IT service-desk tasks, hidden end-state verifiers, with pi + gpt-5.6-sol routed through Lynkr.

The results:

• 31.0% Pass@1 — full 89-task suite • 35.0% Pass@1 / 40.0% Pass@2 — matched 2-attempt methodology • ~0% routing delta vs the model's native harness (35.51%) • $0.87–$0.90/task vs $1.29 native • 92–95% prompt-cache hit rate And the interesting part: The benchmark's binary score hides how close many failures were. 16 failed tasks still completed ≥80% of verifier assertions. One missed passing by 1 assertion out of 32.

In the hardest family, offboarding, failed tasks often completed 60–90% of required actions.

So a task that is 95% correct scores the same as 0%.

By family:

IAM: 6/9 Ops: 4/5 GRC: 3/7 Incident response: ~35% BEC/compromise: 1/5 IPAM/network: 0/5 Offboarding/endpoints: 1/22

For context, the official 5-attempt leaderboard:

Opus-5: 46.07% / $1.75 Grok-4.5: 45.39% / $0.71 GPT-5.6-sol xhigh: 39.10% / $1.53 GPT-5.6-sol high: 35.51% / $1.29 → Lynkr + GPT-5.6-sol high: 31–35% / ~$0.87

The takeaway isn't that Lynkr magically makes the model smarter.

It's that the routing layer adds essentially zero performance degradation while cutting inference cost significantly. And the assertion-level results suggest there's a lot more signal in these agent benchmarks than a binary pass/fail number reveals. Full results coming soon.

What this supports

  • Supports comparing routed and native-harness pass rates, cost per task, and cache hits.
  • Supports the observation that binary scoring hides near-complete failures.

What this does not support

  • Does not support generalizing 31% or 35% into a universal agent success rate.
  • It is one public result with undisclosed logs, scorer, and repeats; the cost is not a universal current rate.

Method, limits, and reproduction

The figures, task set, reasoning tier, and client conditions apply only to the listed source and collection snapshot. Different versions, harnesses, or providers must not be compared directly; undisclosed parameters remain unknown.

For a reproduction, fix the model version, provider or client, reasoning tier, tools, task-set version, sample count, and collection date, and record failures, retries, and human corrections. Full steps are in the source notes below.

GPT-5.6 Sol: Specs, Access, Changes, and the Risks That Still Matter

OpenAI's current GPT-5.6 Sol model page lists a 1.05M context window, 128K max output, reasoning controls, and a time-sensitive API price card. Here is what those facts mean for API, Codex, and browser users.
