Model details

Grok-4.20-Multi-Agent

Grok 4.20 Multi-Agent is designed from the ground up for collaborative, agent-based workflows rather than single-turn interactions. The architecture orchestrates multiple specialized agents that operate in parallel—some handling web searches, others performing data analysis or synthesizing findings—coordinating their efforts to deliver comprehensive, well-sourced answers to complex questions. This multi-agent orchestration makes it particularly strong for deep research tasks that require parallel investigation across different domains, as each agent can focus on a narrow slice of the problem while the system combines their outputs into coherent, unified responses.

The model supports multimodal input, accepting both text and images, which allows agents to incorporate visual context into their reasoning and tool coordination. In benchmark arenas, it has demonstrated strong performance in chat, games, and animation categories, reflecting its ability to handle varied and open-ended tasks. Oracle Cloud Infrastructure documentation notes the model excels at real-time multi-agent research, positioning it as a practical choice for teams and applications that need AI systems to divide labor, coordinate tool use, and synthesize information across agent boundaries into cohesive outputs.

CoverageBenchmark

A third-party technical review of xAI's Grok 4.20 specifically describes the model as a multi-agent large language model with a native 4-agent collaborative architecture, released in March 2026, with full API access following on March 10, 2026. It names the exact variant 'grok-4.20-multi-agent-0309' alongside two sibli The review also highlights a Mixture-of-Experts backbone, four specialized agents working in parallel and debating conclusions, a reasoning and non-reasoning mode pair, and an Arena Elo of 1493 as of April 2026. These third-party specs are not corroborated by the first-party xAI docs page in the supplied set and should

Coverage

The OpenRouter listing for "SpaceXAI: Grok 4.20 Multi-Agent" (slug x-ai/grok-4.20-multi-agent) corroborates the exact model identity and adds concrete technical and availability metadata: modalities are text/vision in with text out, the context window is 2M tokens, and the listed price is $1.25 per 1M input tokens and The same listing specifies reasoning-effort-dependent agent scaling: at low or medium reasoning effort the model uses 4 agents, while at high or xhigh effort it scales up to 16 agents, with the agents operating in parallel to conduct deep research, coordinate tool use, and synthesize information across complex tasks.
