Prompting tips for Grok 4.20 Multi-Agent

• State the goal, not every step. Grok 4.20 Multi-Agent reasons internally — give it the objective, constraints and success criteria and let it plan the approach; over-scripting each step tends to lower quality. Turn effort up for hard problems.
• Huge 2M context — but anchor the ask. You can paste whole documents or codebases; models attend most to the start and end, so put the key instruction at the top and restate it after long inputs.
• It reads images. Send image parts alongside your text and ask for specific outputs (named JSON fields, a table, "what changed") rather than "describe this".
• Constrain JSON with a schema. Use response_format / structured outputs rather than "reply in JSON" to get valid, parseable objects every time.

Tips are derived from Grok 4.20 Multi-Agent's actual capabilities — context window, tool & JSON support, modality and price tier — not generic advice.

Rate limits & reliability

Rate limits here are the DataLLM Lab gateway's, not the upstream vendor's. On 429 (rate limited) or 503 (provider busy), retry with exponential backoff; because Grok 4.20 Multi-Agent is served by 2 providers, requests can fail over to a healthy one automatically. See the error-code guide and failover setup.
