## Google Antigravity

Google Antigravity is Google's entry into agentic software development, positioned as a platform rather than a single editor. Instead of asking an assistant to autocomplete a line, Antigravity is designed around agents that take on whole tasks: they read a codebase, produce artifacts such as plans and verification tests, and report back so a human can review the work. The product is distributed across several surfaces so it can fit different workflows — the Antigravity App as a command center for running multiple local agents in parallel, the Antigravity IDE as the fully featured editor with agent manager and artifacts, the Antigravity CLI for keyboard-driven terminal work, extensions for existing editors, and the Antigravity SDK for building custom agents on the same agent harness.

The platform is explicitly aimed at a broad audience: professional developers working in large enterprise codebases, hobbyists vibe-coding on the side, and everyone in between. Google's marketing highlights use cases like frontend and full-stack development, legacy and codebase migrations, technical debt and backlog burndown, automated testing and QA verification, incident triage and root cause analysis, data pipelines and SQL work, developer onboarding and architecture, and enterprise architecture and strategy.

Antigravity connects to Google's Gemini model line, with the site documenting model releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash, plus agent features like voice mode, custom agents, and a plugin marketplace. It is available for macOS, Windows, Linux, and Googlebook, and Google states it is available at no charge for developers.

**Pricing & Plans:** Free to download and use for individual developers according to Google's own site; organization and enterprise plans are offered separately (pricing on request). Model and quota details can change, so check the official pricing page before committing a team.

- **Multiple agent surfaces:** A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
- **Parallel local agents:** Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
- **Artifacts and verification:** Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
- **Built on Gemini models:** Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
- **Agent SDK for custom agents:** Use short Python scripts against the Antigravity harness to prototype custom agents, automate engineering tasks, and run evaluations.

**Strengths:** Free for individual developers and available on macOS, Windows, Linux, and Googlebook; Covers many surfaces — app, IDE, CLI, extensions, SDK — so different workflows are supported; Backed by Google and its Gemini models with a steady release cadence; Verification-oriented: artifacts and tests make agent output easier to review

**Limitations:** Tied to Google's Gemini model line rather than being model-agnostic; Enterprise pricing is not published, so costs require contacting sales; Rapid model and feature changes mean quotas and capabilities can shift

## KAT-Dev

KAT-Dev is an open-weight large language model created by Kwaipilot and aimed at coding and software engineering workflows. With 33 billion parameters, it is designed to help developers generate code, fix bugs, refactor existing logic, write tests and produce documentation. The model is published openly, so engineering teams can pull the weights and run them in their own infrastructure or rely on third-party inference providers that already serve it.

What sets KAT-Dev apart is its focus on repository-scale coding assistance rather than generic chat. It supports tool-calling and a structured prompt format that lets it interact with a computer or coding agent to complete multi-step tasks, which makes it suitable for agentic developer tooling and automated software tasks. The model is tagged as multilingual and conversational on its distribution page.

Because KAT-Dev is licensed under Apache-2.0, it can be embedded into commercial products and internal tools. Developers typically evaluate it against established coding benchmarks and integrate it through transformers-based pipelines or an API endpoint. Note that kat-dev.dev occasionally blocks automated crawlers; the project itself remains available through its public model repositories.

**Pricing & Plans:** KAT-Dev is released as open weights under the Apache-2.0 license, so the model itself is free to download and self-host. Costs apply only to the compute you use (your own GPUs or a paid third-party inference provider).

- **33B open-weight coding model:** A 33-billion-parameter language model released with open weights for self-hosting and customization.
- **Software-engineering focus:** Optimized for code generation, bug fixing, refactoring, performance optimization, test generation and code documentation.
- **Agentic tool calling:** Supports a structured tool-call format so it can operate inside coding agents and complete multi-step tasks.
- **Apache-2.0 license:** Permissive licensing allows commercial and internal use, fine-tuning and redistribution.
- **Inference-provider ready:** Available through mainstream inference providers and transformers-compatible pipelines for quick adoption.

**Strengths:** Open weights under a permissive Apache-2.0 license; Strong coding and repository-level reasoning focus; Self-hostable for data-sensitive engineering teams; Available through public inference providers for quick testing

**Limitations:** 33B parameters need meaningful GPU resources to self-host; Not a managed SaaS product with an official hosted dashboard; Requires benchmark evaluation and tuning to fit specific codebases
