Pricing	usage	usage
Strengths	+ Aggressive pricing ($1.25 input / $2.50 output per million tokens) for a 1M-context flagship + Vendor-reported leadership in agentic tool calling and instruction following + Companion multi-agent variant (grok-4.20-multi-agent) targeted at agentic workloads	+ Strong retrieval quality on general-domain text + API-based; no embedding infrastructure to host
Tradeoffs	− Stated knowledge cutoff of November 2024 is older than competing flagships − Rapid model churn; xAI retired eight legacy models (including grok-3) in May 2026, so pinned integrations need active migration	− API-only; document text leaves your environment to be embedded − Adds a second vendor alongside the generation model
