Category	model	model
Vendor type	commercial	commercial
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 general-purpose retrieval quality across English and non-English text + Ubiquitous ecosystem support in vector databases and RAG frameworks + Simple usage-based pricing with a cheaper small variant for cost-sensitive paths
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 (no open weights or on-prem option) − General-purpose model with no domain-specialized variants, unlike some competitors
