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.

Solar Pro 3: common questions

How does Solar Pro 3 rank among AI models?

Solar Pro 3 is a superseded version and is not on the current board as of 6 November 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.

How much does Solar Pro 3 cost per 1M tokens?

No live API price is listed for Solar Pro 3 in the current snapshot as of 6 November 2026 because no serving endpoint is published. ModelCap shows a price only when a provider currently lists one.

What is the context window of Solar Pro 3?

Solar Pro 3 has a published context window of 131K tokens (131,072). The snapshot lists a 117,964 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration. Limits can vary by provider and prompt length; a model-wide maximum has not been independently verified. The providers table lists each endpoint's context limit.

Is Solar Pro 3 open-weight?

No linked weights. No downloadable model weights are linked in the current source data. This does not identify every API or chat product that offers the model.

When was Solar Pro 3 released?

Solar Pro 3 first appeared in the catalogue on 27 Jan 2026. It has since been superseded by Solar Pro 4. Rank and price movements since then are recorded on the site's changes feed.
