Category	model	model
Vendor type	commercial	commercial
Pricing	usage	usage
Strengths	+ Very long context + Native multimodal (image/video/audio) + Competitive pricing per token	+ 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
Tradeoffs	− Tool-use ergonomics differ from OpenAI/Anthropic − Smaller agent-framework ecosystem	− 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
