Antigravity Agent vs GLM 5.3

This comparison does not currently contain a protocol-matched coding benchmark for both Antigravity Agent and GLM 5.3, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

Only GLM 5.3 has a directly sourced input price: $1.20 per million tokens. Only GLM 5.3 has a directly sourced output price: $4.00 per million tokens.

Antigravity Agent has the larger sourced context window. Antigravity Agent supports 1,049K and GLM 5.3 supports 1,000K.

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; GLM 5.3 is not marked open weight.

Antigravity Agent is documented with image input; GLM 5.3 is not documented with image input. This reflects supported input modalities, not vision quality.

GLM 5.3 has the larger sourced maximum output: Antigravity Agent supports 66K and GLM 5.3 supports 131K output tokens.

Antigravity Agent: reasoning, tool calling, and image input. GLM 5.3: reasoning and tool calling. Feature support does not establish relative quality.

Antigravity Agent has 2 sourced provider routes; GLM 5.3 has 4, so GLM 5.3 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.
