Google Antigravity vs Cursor (2026): $19.99 vs $20 Pricing, Gemini 3.5 Flash vs Composer, and the Multi-Agent Split

Summary

Antigravity 2.0 leads on a fast default model, two surfaces (desktop and CLI), parallel subagents, and a self-hosting SDK. Cursor leads on a mature single-editor workflow, a separate cheaper agent pool for everyday coding, and Bugbot agentic reviews. For multi-surface agent orchestration, pick Antigravity. For a stable daily driver, pick Cursor.

Pricing and Rate Limits

Antigravity prices through Google subscriptions. Google AI Pro is $19.99/mo and adds higher rate limits to the agent model in Antigravity plus Gemini 3.1 Pro at 4x free limits. Google AI Ultra starts at $99.99/mo with the highest rate limits and up to 20x Pro usage; reported structure puts a $100/mo Ultra tier at a 5x Pro token budget and the $200/mo tier at 20x (a price cut from $250).

Cursor prices through included API usage. Pro at $20/mo includes about $20 of API-rate model usage, Pro+ at $60/mo includes $70, and Ultra at $200/mo includes $400. Selecting Auto or Composer 2.5 draws from a separate, more generous pool, so model choice changes your burn rate. The free Hobby tier needs no credit card and gives limited Agent requests and limited Tab completions.

Models: Gemini 3.5 Flash vs Composer 2.5

Antigravity defaults to Gemini 3.5 Flash, released May 19, 2026. It scores 76.2% on Terminal-Bench 2.1, 55.1% on SWE-bench Pro (public, single attempt), 83.6% on MCP Atlas, and 56.5% on Toolathlon. Google describes it as 4x faster than other frontier models on output tokens per second. Gemini 3.5 Pro was reported as rolling out in June 2026.

Cursor defaults to Composer 2.5, its in-house agent line as of June 2026. It is billed from a separate, larger included pool designed for everyday agentic coding at lower cost than frontier API models. Both tools let you switch to frontier models: Cursor exposes Claude Opus 4.8 ($5/M input, $25/M output) and GPT-5.5; Antigravity runs Gemini 3.1 Pro and the agent model lineup.

The Multi-Agent Difference

Antigravity 2.0 ships as a unified harness with two surfaces: a redesigned desktop app and a standalone CLI. It adds specialized subagents that run tasks in parallel, cross-platform terminal sandboxing, credential masking, and hardened Git policies. The Managed Agents API provisions agents with remote sandboxes, and the Antigravity SDK supports self-hosted deployments. That is a wider surface than any single-IDE tool.

Cursor runs one fast agent loop inside its editor, with Composer 2.5 as the default and cloud agents for background work. Bugbot adds agentic code reviews on usage-based billing. The workflow is editor-centric by design, which is why it feels more predictable, and why Antigravity reads as the bet on where agent-first development is heading.

Benchmarks

Cursor has not published a SWE-bench or Terminal-Bench score for Composer 2.5, so it is omitted rather than estimated. On Terminal-Bench 2.1, Antigravity's default Gemini 3.5 Flash (76.2%) lands between Gemini CLI with Gemini 3.1 Pro (70.7%) and Claude Code with Opus 4.8 (78.9%). Both Antigravity and Cursor can run the higher-scoring frontier models, so the harness, not the default model, is the real decision.

Where Antigravity Wins

Antigravity is the stronger pick for parallel agent work that spans the terminal and the editor, and for teams that want to provision or self-host agents through an SDK. Gemini 3.5 Flash as the default keeps iteration fast.

Where Cursor Wins

Cursor is the dependable default when you want one editor, predictable included usage, and a cheaper agent pool for routine work. Teams that need SSO and review automation get it without leaving the tool.

Run Open-Source Models Cheaper Behind Either Tool

Both Antigravity and Cursor let you point at an OpenAI-compatible endpoint, which is where inference price and quality stop being the tool's problem and start being the provider's. Most serverless providers quantize activations to fp8 to cut cost, which degrades output. Morph serves DeepSeek with 16-bit (bf16) activations and no fp8 or int8 quantization, so responses match the reference weights. That makes it the best place to run DeepSeek when output fidelity matters.

For codegen specifically, Morph runs code-tuned speculative decoding plus custom low-level inference kernels, which makes it the fastest and highest-quality option for coding agents rather than a general-purpose menu. morph-dsv4flash (DeepSeek V4 Flash) is $0.139 per 1M input tokens and $0.278 per 1M output tokens. See pricing for the full model list.

Frequently Asked Questions

Is Google Antigravity cheaper than Cursor?

By 1 cent at the entry tier. Antigravity's agent runs at higher rate limits on Google AI Pro at $19.99/mo; Cursor Pro is $20/mo and includes about $20 of API-rate usage. At the top, Google AI Ultra starts at $99.99/mo while Cursor Ultra is $200/mo with $400 of included usage. Compare rate limits and included usage, not headline price.

What is Antigravity 2.0?

Announced at Google I/O on May 19, 2026. It splits into a redesigned desktop app and a standalone CLI, defaults to Gemini 3.5 Flash, and adds specialized subagents, terminal sandboxing, credential masking, hardened Git policies, a Managed Agents API, and an Antigravity SDK for self-hosting.

Which has the better default model?

Antigravity defaults to Gemini 3.5 Flash: 76.2% on Terminal-Bench 2.1, 55.1% on SWE-bench Pro, and 4x faster output tokens per second per Google. Cursor defaults to Composer 2.5 on a separate cheaper pool. Both can switch to Claude Opus 4.8 (78.9% Terminal-Bench 2.1) and GPT-5.5 (83.4%).

Is Google Antigravity free?

No fully free Antigravity tier is verified in our data. Access runs through Google AI Pro ($19.99/mo) for higher agent rate limits or Google AI Ultra (from $99.99/mo). Cursor has a free Hobby tier with no card, limited Agent requests, and limited Tab completions.

What changed with Antigravity quotas in June 2026?

In early June 2026 Google wiped the quota counters to zero for all free and paid Gemini users and shipped a refreshed Gemini 3.5 Flash build to Antigravity to fix post-launch issues.
