Not independent measurement

Structured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. They remain quarantined until dataset revision, harness, configuration and identity pass ModelCap’s independent admission review.

These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.

The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

Apertus v1.5 70B: common questions

How does Apertus v1.5 70B rank among AI models?

Apertus v1.5 70B has no public ModelCap Index position as of 22 September 2026: the snapshot lacks enough matched benchmark evidence, or the identity match is unresolved. Its catalogue facts (price, context, providers) are shown without a rank.

How much does Apertus v1.5 70B cost per 1M tokens?

No live API price is listed for Apertus v1.5 70B in the current snapshot as of 22 September 2026 because the latest endpoint refresh was unavailable. ModelCap shows a price only when a provider currently lists one.

Is Apertus v1.5 70B open-weight?

Gated access (apache-2.0). The weights are hosted behind an access request or acceptance step. Review the publisher's access requirements and license before use or redistribution. The repository is swiss-ai/Apertus-v1.5-70B on Hugging Face.

When was Apertus v1.5 70B released?

Apertus v1.5 70B first appeared in the catalogue on 24 Jul 2026. It is the current version in its family. Rank and price movements since then are recorded on the site's changes feed.
