Antigravity Agent vs Grok 4.20 Multi Agent

This comparison does not currently contain a protocol-matched coding benchmark for both Antigravity Agent and Grok 4.20 Multi Agent, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Only Grok 4.20 Multi Agent has a directly sourced input price: $1.25 per million tokens. Only Grok 4.20 Multi Agent has a directly sourced output price: $2.50 per million tokens.

Antigravity Agent has the larger sourced context window. Antigravity Agent supports 1,048,576 tokens and Grok 4.20 Multi Agent supports 1,000,000 tokens.

There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.

Both models have the same sourced self-hosting status: unsupported. Antigravity Agent is not marked open weight; Grok 4.20 Multi Agent is not marked open weight.

Antigravity Agent is documented with image input; Grok 4.20 Multi Agent is documented with image input. This reflects supported input modalities, not vision quality.

Antigravity Agent has a sourced maximum output of 65,536 tokens; Grok 4.20 Multi Agent's maximum output is not reported. A larger limit cannot be determined.

Antigravity Agent: reasoning, tool calling, and image input. Grok 4.20 Multi Agent: reasoning, tool calling, and image input. Feature support does not establish relative quality.

Antigravity Agent has 2 sourced provider routes; Grok 4.20 Multi Agent has 1, so Antigravity Agent has broader tracked availability.

There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
