If a model scores 8.53 out of 10 yet answers only 67% of 50 attempts, the score reflects the calls that came back. Shouldn't coverage be weighed alongside conditional quality before we judge its value?

GPT-5.6 Sol scores 8.53 out of 10 on public response generation — but only on the 67% of 50 attempts that answered. A conditional quality score can look strong while a third of attempts come back empty.

Same family, different leads: GPT-5.6 Luna took 19 of 43 content-summarization comparisons, while Terra took 13 of 43 claim-referenced analyst-writing comparisons. A family name alone can't tell you which variant wins.

Treat a 97.1% first-time usable rate (199,026 attempts, Gemini 3.1 Flash Lite) as an entry filter: it shows a model clears the retry bar. It says nothing about answer quality, so it should not be used to rank models.

Gemini 3.1 Flash Lite returned a usable answer first time on 97.1% of its 199,026 attempts, with no repair or retry. That figure tells a workflow how much repair and retry handling to plan for. It does not show the answers are good enough for the work.

GLM-5.3 Flash scores 8.27 out of 10 on Authoritative Source Selection when it answers — but it only answers on 89.2% of 30 attempts. Completion leaders differ (99.9% of 30,332 attempts), so quality alone does not name one general winner.

Caveat on 8.27/10: GLM-5.3 Flash answers only 89% of attempts (n=30) on Authoritative Source Selection, so the quality point estimate is conditioned on calls that came back. Selection based on that number alone can overstate real-world usefulness.

GLM-5.3 Flash posts 8.27 out of 10 on Authoritative Source Selection — but only on the 89% of attempts (n=30) it answered. A quality score averaged over returned calls can't tell you how often you get nothing at all.

Across five models, first-time usable answers range from 96.2% of 93,617 attempts (Gemini 3.5 Flash) to 99.9% of 30,332 attempts (meta/muse-spark-1.3-contributor). Measurable spread, but just 3.7 points separate the field.

A strong answer score doesn't validate the whole chain. First-time usable answers ranged from 99.4% of 135,870 attempts (Nemotron-3 Nano 30B-A3B) to 95.7% of 3,485 (qwen3.6-plus) and 95.3% of 2,558 (Nemotron-3 Super 120B) — no repair, no retry. Reliability must be measured on its own.

First-attempt reliability isn't close across models: NVIDIA Nemotron-3 Nano 30B-A3B returned a usable answer on 99.4% of 135,870 attempts (no repair, no retry), vs 95.7% of 3,485 for qwen3.6-plus and 95.3% of 2,558 for Nemotron-3 Super 120B. That spread makes reliability its own dimension.

Language detection: the top two tied on 97.2% of 71 occasions, median gap 0.0 of 10 points. Yet on subreddit_selection one model took 25 of 29 contests. Stage, not the task, decides how much model choice matters.

If Meta Muse Spark 1.1 wins 39 of 45 at_content_domain_suggest appearances (86.7%) and GPT-5.6 Sol wins 25 of 29 subreddit_selection appearances (86.2%), then comparisons should be organized by decision stage—not settled with one overall winner.

No single model wins everywhere. Meta Muse Spark 1.1 was judged best on at_content_domain_suggest in 39 of 45 appearances (86.7%), while GPT-5.6 Sol led subreddit_selection in 25 of 29 appearances (86.2%). Different models, different tasks.

If you want one default for this category, which task are you buying it for? meta/muse-spark-1.1's 86.7% (39 of 45) is at_content_domain_suggest; GPT-5.6 Sol's 86.2% (25 of 29) is subreddit_selection. A benchmark licenses the task it measured, not the whole category.

Two tasks, two winners: meta/muse-spark-1.1 was judged best in 39 of 45 appearances (86.7%) on at_content_domain_suggest; GPT-5.6 Sol in 25 of 29 (86.2%) on subreddit_selection. Each lead stays on its own task — neither is a category-wide default.

Task matters. On at_content_domain_suggest, meta/muse-spark-1.1 was judged best in 39 of 45 appearances (86.7%). On language-detection, the top two tied in 97.2% of 71 judged occasions, so the same leader-picking logic doesn't carry over.

Choosing from an overall ranking risks picking wrong: Claude Opus 5's 10 of 25 best answers (40.0%) came on Topic Cluster Labeling, not on relevance_scoring_post or executive_summary_generation, where Moonshot Kimi K3 took 8 of 26 (30.8%) on each. Establish standing per task.

Best-answer standing is per task, not overall. Claude Opus 5 was judged best in 10 of 25 occasions (40.0%) on Topic Cluster Labeling; Moonshot Kimi K3 was judged best in 8 of 26 (30.8%) on relevance_scoring_post and 8 of 26 (30.8%) on executive_summary_generation...

MiniMax-M3 fails on 5.0% of 35,961 attempts, yet 18.1% of attempts needed repair. Only 76.9% were usable as returned. Failure rate and usable output are different measures.

If a quality score counts only the answers that came back, what does it say about a model that returned none in 31 attempts? Inkling's 7.93/10 on Public Response Generation is measured only on calls that came back, and it answered on 0% of attempts.

Thinking Machines Inkling scores 7.93/10 on Public Response Generation when it answers. It answered on 0% of attempts (n=31). In an unattended workflow, that quality score never reaches a user. Coverage must be read alongside quality.

The two leaders finished within half a point on 97.2% of 71 judged occasions — and scored exactly the same on that same 97.2%. Median gap 0.0 on a 10-point scale: the separation isn't there.

Implication: ranking DeepSeek V4 Flash by its 9.88/10 on Language Identification scores only the 84.6% of 331 attempts that came back — the rest deliver no measured quality at all.

DeepSeek V4 Flash scores 9.88 out of 10 on Language Identification — but only across the 84.6% of 331 attempts it answered. Without that answer rate, conditional quality reads as unconditional delivery.

A 5.0% failure rate looks clean. Counting repairs changes the picture: of 35,961 MiniMax-M3 attempts, 18.1% needed repair and 76.9% were usable as returned. Failure rate and repair burden measure different things.

On relevance_scoring_x_post, the top two finished within half a point in 53.8% of 80 judged occasions (median gap 0.5). When scores sit this close, completion behavior deserves weight too. GPT-5.6 Luna returned a usable answer first time on 98.6% of 142,447 attempts.

On auto_reddit_post_generation, the top two answers scored exactly the same in 4.9% of 82 judged occasions and finished within half a point in 79.3%. Median gap: 0.3 on a 10-point scale. Model choice barely moved the result.

Thinking Machines Inkling posts 7.93 out of 10 on Public Response Generation yet answers on 0% of its 31 attempts; GPT-5.6 Luna returns a usable first-time answer on 98.6% of its 142,447 attempts. Read the returned-answer score beside the chance of an answer.

On relevance_scoring_x_post the top two answers tied in 11.2% of 80 judged occasions, median gap 0.5 on a 10-point scale. If quality barely separates, what should decide a pick for an unattended workflow? Whether it answers usable first time.

GPT-5.6 Luna gives a usable answer first time on 98.6% of 142,447 attempts, and Gemini 3.1 Flash Lite on 97.1% of 199,026 — no repair, no retry. For unattended workflows, first-pass usability is the admission gate for model selection.

NVIDIA Nemotron-3 Nano 30B-A3B's 99.4% comes from 135,870 attempts; GLM-5.3 Flash's 89.2% comes from 30. Same kind of percentage, vastly different weight — the denominator decides what it means.

GLM-5.3 Flash scores 8.27 out of 10 on Authoritative Source Selection, but it answers on only 89.2% of 30 attempts. Quality scores come only from calls that returned, so reliability has to be checked separately from quality.

First-time usable-answer rates differ across models. Gemini 3.5 Flash returned one on 96.2% of 93,617 attempts; NVIDIA Nemotron-3 Nano 30B-A3B did so on 99.4% of 135,870. Reliability has to be measured model by model.

Usable-answer rates count all attempts: GPT-5.6 Luna answered first time on 98.6% of 142,447 attempts; Gemini 3.1 Flash Lite on 97.1% of 199,026. Answering is a separate dimension that a conditional quality score misses.
