It registers an Artificial Analysis Intelligence Index score of 19 out of 55, placing it slightly below the average of 20 for comparable models. This indicates its suitability for straightforward tasks rather than those demanding deep analytical capabilities or intricate problem-solving. In terms of speed, Solar Mini delivers a median output of 79 tokens per second, with a specific benchmark showing 76.1 tokens per second. While functional, this speed is slower than the average of 93 tokens per second, suggesting that it might not be the fastest option for high-throughput, real-time applications. Its latency, or time to first token (TTFT), is measured at 1.05 seconds on the Upstage platform, which is a reasonable figure for many interactive use cases.
The pricing structure for Solar Mini is straightforward, with both input and output tokens priced at $0.15 per 1 million tokens. When compared to market averages, its input token price is considered somewhat expensive, contrasting with an average of $0.10 per 1 million tokens. Conversely, its output token price is moderately priced, sitting below the average of $0.20 per 1 million tokens. This uniform pricing model simplifies cost estimation, but users should be mindful of the higher input cost, especially for applications involving substantial prompt lengths or frequent interactions. The blended price, based on a 3:1 input-to-output token ratio, also stands at $0.15 per 1 million tokens, reflecting this consistent rate.
Given its characteristics, Solar Mini is best suited for applications where cost predictability, open-source flexibility, and moderate performance are key. It excels in tasks like short-form content generation, summarization of brief texts, rephrasing, and basic customer service responses. Its 4k context window and non-reasoning nature mean it's not designed for complex analytical workloads or extended conversational AI, but rather for efficient, direct generative outputs. For developers prioritizing an open ecosystem and seeking a reliable model for well-defined, less cognitively demanding tasks, Solar Mini offers a compelling, accessible solution.

These real-world scenarios demonstrate that Solar Mini offers a cost-effective solution for many common generative tasks, especially those with moderate token counts. While its input price is slightly higher than average, the uniform pricing and moderate output cost keep individual transaction expenses low. For applications requiring frequent, short interactions, the cumulative cost remains manageable, making it a viable option for budget-conscious deployments.
Optimizing costs when using Solar Mini involves strategic prompt engineering and understanding its performance characteristics. By implementing a few key practices, you can maximize efficiency and ensure that your AI budget is spent effectively.
The following playbook provides actionable strategies to mitigate potential cost increases and leverage Solar Mini's strengths for various applications.
Solar Mini's 4k token context window means that every token you send in counts towards your input cost. For tasks where information density is crucial, ensure your prompts are concise and directly relevant. Avoid including unnecessary conversational filler or redundant instructions.
While specific verbosity data is unavailable, you can still guide Solar Mini to produce outputs of an appropriate length, thereby controlling output token costs. Explicitly instruct the model on the desired length or format of the response.
Solar Mini's slower output speed (76.1 tokens/s) can be a factor for high-volume tasks. To mitigate this, consider batching multiple requests together and processing them asynchronously, rather than waiting for each individual response.
As a non-reasoning model with below-average intelligence, Solar Mini is best utilized for tasks that align with its capabilities. Using it for complex analytical or highly creative tasks might lead to unsatisfactory results, requiring more re-prompts and thus increasing costs.
Regularly monitoring your token usage and costs is crucial for identifying inefficiencies and optimizing your budget. Leverage Upstage's analytics tools or integrate your own tracking mechanisms.
