Solar Mini 4

upstage/solar-mini4

Solar Mini 4 is Upstage's compact, cost-efficient language model, a 35B-parameter mixture-of-experts with 3B active parameters and a 524K context window.

Input price: $0.05 / 1M tokens
Output price: $0.20 / 1M tokens
Context window: 524K tokens
Max output: 131K tokens
Accepts: Text
Returns: Text

Example: 1,000 requests with 1,000 input and 500 output tokens each would cost about $0.15 (1M input tokens × $0.05 + 0.5M output tokens × $0.20). Estimate your own usage.

Prices are the provider’s own per-token rates with zero markup, from our price list as of Oct 18, 2026. If a call has extra provider charges (images, audio, web search, cached prompts), you pay the reported cost.
