Antigravity Agent vs Granite 4.2 3B

This comparison does not currently contain a protocol-matched coding benchmark for both Antigravity Agent and Granite 4.2 3B, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Only Granite 4.2 3B has a directly sourced input price: $0.030 per million tokens. Only Granite 4.2 3B has a directly sourced output price: $0.12 per million tokens.

Antigravity Agent has the larger sourced context window. Antigravity Agent supports 1,049K and Granite 4.2 3B supports 131K.

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

Granite 4.2 3B is the only model in this pair currently marked as self-hostable. Antigravity Agent is not marked open weight; Granite 4.2 3B is open weight.

Antigravity Agent is documented with image input; Granite 4.2 3B is not documented with image input. This reflects supported input modalities, not vision quality.

Neither has a larger sourced maximum output. Antigravity Agent is 66K and Granite 4.2 3B is —.

Antigravity Agent: reasoning, tool calling, and image input. Granite 4.2 3B: reasoning and tool calling. Feature support does not establish relative quality.

Antigravity Agent has 2 sourced provider routes; Granite 4.2 3B 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.
