Same workload at 1,500/500 tokens × 10,000 req/month: $150 → $88. 2× cheaper on input.
TrackCost's gateway auto-detects which requests are safe to route to the cheaper model and flags the ones that need Grok's full capability. You stay in control — we surface the opportunity.
Grok costs $0.00500 per 1,000 input tokens and $0.01500 per 1,000 output tokens as of the current xAI API pricing.
GPT-4o is significantly cheaper than Grok (2× cheaper on input) and often works fine for tasks that don't need Grok's full capability. TrackCost automatically suggests model downgrades where safe.
The three highest-leverage ways: (1) route requests to a cheaper model where possible, (2) cache identical requests so you don't pay twice for the same response, (3) set hard monthly budgets that block requests when exceeded. TrackCost automates all three at the gateway layer.
Grok supports up to 128,000 tokens of context. For comparison with other models, use the TrackCost savings calculator.
