Grok 4.20 Multi-Agent API: orchestration with a 2M context window

Grok 4.20 Multi-Agent is xAI's orchestration-focused variant, built for coordinating complex, multi-step workflows. It shares Grok 4.20's 2M-token context window and adds tuning for breaking work into parallel sub-tasks. Pricing is $2.80 per 1M input tokens and $8.40 per 1M output tokens.

Through YepAPI you reach Grok 4.20 Multi-Agent with one OpenAI-compatible API key. The same key covers other models and YepAPI's SEO, SERP, and web-scraping endpoints, so your agents can plan tasks and gather web data through a single integration.

What is Grok 4.20 Multi-Agent?

Grok 4.20 Multi-Agent is xAI's multi-agent variant of Grok 4.20, optimized for orchestrating complex, multi-step workflows rather than single-turn answers. It is built to decompose a goal into sub-tasks, track dependencies between them, and coordinate intermediate results. It keeps Grok 4.20's enormous 2,000,000-token context window and supports up to 16,384 output tokens per response, so it can hold an entire workflow's state, large tool outputs, and long histories in one place. Its strong reasoning makes it a fit for planning and delegation inside agent systems. Pricing is $2.80 input and $8.40 output per 1M tokens.

Build with Grok 4.20 Multi-Agent via YepAPI

Call the OpenAI-compatible /v1/ai/chat endpoint with your YepAPI key. The Chat Completions schema lets you drop it into existing agent frameworks by changing the base URL and model name. Use it as the planner or coordinator in multi-agent architectures, passing tool results and sub-agent outputs back through its 2M-token window. One key also unlocks other models plus SEO, SERP, and scraping APIs, so the agents it orchestrates can fetch live web data without separate provider accounts.

Grok 4.20 Multi-Agent API pricing — $2.80 / $8.40 per 1M tokens

Grok 4.20 Multi-Agent costs $2.80 per 1M input tokens and $8.40 per 1M output tokens. Because orchestration workflows often replay large contexts across many turns, the input rate matters most; at this price you can run agent loops that carry substantial state without runaway costs. Billing is per token, so simpler coordination steps stay inexpensive while the 2M window is available when you need it.

Grok 4.20 Multi-Agent for agentic workflows

The model is purpose-built for agent systems that plan, delegate, and combine results: research pipelines, automated software workflows, and tools that fan work out into parallel steps. The 2M-token context lets a coordinator keep every sub-task's output in view before synthesizing a final result, while its reasoning handles dependency management. It is a strong choice as the orchestrating brain over a swarm of specialized model calls.
