Grok 4.20 Multi-Agent (0309)

Beta

Marked Beta on the official model page; designed for multi-agent orchestration. Aliases include grok-4.20-multi-agent, grok-4.20-multi-agent-latest. Modality 'text, image -> text'. Lower rate limits than the standard 4.20 SKUs (9 req/s, 2.5M tokens/min vs 37 req/s, 10M tokens/min). Pricing and cached input ($0.20/M) confirmed on official model page. Official docs list a 1M context window; one third-party source claims 2M but this is NOT corroborated by docs.x.ai, so 1M is used.
