Editorial Analysis
Profile. Solar Pro 4 is a budget-tier option from Upstage at $1.20/M output tokens. Despite the low price, it scores competitively on Coding Index (52.7) and Intelligence Index (41.6) — making it a candidate for high-volume production workloads where unit cost dominates.
Latency. On latency, Solar Pro 4 reports 62 tok/s output speed and 2140ms time-to-first-token. Output speed is on the slower end; for real-time chat consider pairing with a streaming front-end or routing latency-sensitive requests to a faster model.
Cost model. For a workload of 1M input tokens + 100K output tokens, Solar Pro 4 costs $0.42 per million input-equivalent requests. Multiply by your monthly request volume to project the bill, and compare against the speed/correctness profile above to decide if the trade-off is worth it for your workload.
