How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Grok 4.20 Multi-agent, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
Grok 4.20 Multi-agent is a proprietary model with a 2M context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Tracked as unresolved. xAI's current docs use the Grok 4.20 Multi-agent name, but there is still no clean exact-value benchmark table and the capability docs still describe multi-agent as beta.
Grok 4.20 Multi-agent sits in the Grok 4.20 family with Grok 4.20. The profile has no source-displayable benchmark row yet.

Frequently asked questions
How does Grok 4.20 Multi-agent perform overall in AI benchmarks?
Grok 4.20 Multi-agent does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.
Which sibling models are related to Grok 4.20 Multi-agent?
Grok 4.20 Multi-agent belongs to the Grok 4.20 family. Related tracked variants include Grok 4.20. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Grok 4.20 Multi-agent have full benchmark coverage on BenchLM?
No. Grok 4.20 Multi-agent currently has 0 source-displayable rows across 435 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Grok 4.20 Multi-agent?
Grok 4.20 Multi-agent has a reported context window of 2M in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
