Editorial Analysis
Profile. Grok 4.3 (high) is a budget-tier option from xAI at $2.50/M output tokens. Despite the low price, it scores competitively on Coding Index (42.2) and Intelligence Index (37.9) — making it a candidate for high-volume production workloads where unit cost dominates.
Latency. On latency, Grok 4.3 (high) reports 146 tok/s output speed and 20940ms time-to-first-token. Output speed is in the normal range — most chat and completion applications will be token-bound, not streaming-bound.
Cost model. For a workload of 1M input tokens + 100K output tokens, Grok 4.3 (high) costs $1.50 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.
