Antigravity Agent vs o3-pro

This comparison does not currently contain a protocol-matched coding benchmark for both Antigravity Agent and o3-pro, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Only o3-pro has a directly sourced input price: $20.00 per million tokens. Only o3-pro has a directly sourced output price: $80.00 per million tokens.

Antigravity Agent has the larger sourced context window. Antigravity Agent supports 1,049K and o3-pro supports 200K.

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 recorded self-hosting status: unsupported. Antigravity Agent is not marked open weight; o3-pro is not marked open weight.

Antigravity Agent is documented with image input; o3-pro is documented with image input. This reflects supported input modalities, not vision quality.

o3-pro has the larger sourced maximum output: Antigravity Agent supports 66K and o3-pro supports 100K output tokens.

Antigravity Agent: reasoning, tool calling, and image input. o3-pro: reasoning, tool calling, and image input. Feature support does not establish relative quality.

Antigravity Agent has 2 sourced provider routes; o3-pro has 2, a tie.

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.
