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

BES evidence selected · measured input only

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Solar Pro 3 is a superseded version and is not on the current board as of 22 September 2026.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?

Solar Pro 3 is listed at $0.15 per 1M input tokens and $0.60 per 1M output tokens as of 22 September 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $0.60 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.

What is the context window of Solar Pro 3?

Solar Pro 3 has a published context window of 131K tokens (131,072) and a maximum output of 118K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.

Is Solar Pro 3 open-weight?

API only. No downloadable model weights are linked in the current source data; access is through a hosted API or product.

Which API providers serve Solar Pro 3?

One provider serves Solar Pro 3 through OpenRouter as of 22 September 2026: Upstage. Each provider's price, context limit, quantization and measured uptime are in the providers table above.

Which benchmarks has Solar Pro 3 been evaluated on?

Solar Pro 3 has published results on 3 public boards tracked by ModelCap as of 22 September 2026: AA Intelligence Index 7.8 (#142 of 151), AA τ²-Bench Telecom 86.3% (#92 of 436) and AA Humanity's Last Exam 10.3% (#285 of 615). Each board page ranks every tracked model on that benchmark; the ModelCap Index combines them with published uncertainty.

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 It has since been superseded by Solar Pro 4.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.
