Frequently Asked Questions about Solar Pro
How much does the Solar Pro API cost per 1M tokens?+
Solar Pro by Upstage is priced at $0.25 per 1M input tokens and $0.25 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.025 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Solar Pro pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in Solar Pro's context window?+
Solar Pro features a 33K tokens context window, which equals approximately 24,576 English words or ~66 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run Solar Pro locally on my own GPU (Open Weights)?+
No, Solar Pro is a proprietary closed-weights model hosted by Upstage. It cannot be downloaded for local GPU execution and must be accessed via Upstage's official API or cloud platform.
Does Upstage train on data sent to the Solar Pro API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Upstage Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Upstage Cloud API & Enterprise Endpoints.
How does Solar Pro perform on coding and reasoning benchmarks?+
Solar Pro achieves a composite Intelligence Index of 75/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 73.5% on MMLU-Pro, and 1260 pts on Chatbot Arena Elo.
What is Solar Pro best used for?+
Solar Pro is best suited for: Ideale per il ragionamento aziendale di frontiera, la programmazione avanzata e i carichi di produzione, sistemi RAG aziendali e integrazioni API scalabili.. Assessment: Con un indice di intelligenza di 75/100, contesto da 33K e 100 tok/s, Solar Pro rappresenta una soluzione solida e ad alto valore nel catalogo Upstage.
AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Solar Pro:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
An open standard created by Anthropic that allows AI applications and agents to connect seamlessly to local filesystems, development environments, and third-party APIs via standardized server interfaces.
A cost and latency optimization where inference providers store pre-computed attention states for repeated prompt prefixes. Reusing cached tokens typically slashes API input costs by 50% to 90% and cuts TTFT substantially.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
