Agent Development Kit (ADK) vs Grok Code Fast 1

Agent Development Kit (ADK) and Grok Code Fast 1 are both large language models tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Agent Development Kit (ADK)

ADK is the open-source agent development framework that lets you build, debug, and deploy reliable AI agents at enterprise scale.

Grok Code Fast 1

<cite index="2-1">Released in late August 2025, the xAI Grok Code Fast 1 model is a coding-focused AI model that excels at common, high-volume coding task and is designed especially for agentic coding workflows.</cite> <cite index="1-6,1-7,1-8">Built from scratch with a brand-new model architecture, it was trained on a pre-training corpus rich with programming-related content, and curated high-quality datasets that reflect real-world pull requests and coding tasks.</cite> <cite index="1-23">The model is particularly adept at TypeScript, Python, Java, Rust, C++, and Go.</cite> <cite index="1-13">The model is generally available via the xAI API, priced at $0.20 / 1M input tokens, $1.50 / 1M output tokens, and $0.02 / 1M cached input tokens.</cite>

Attribute	Agent Development Kit (ADK)	Grok Code Fast 1
Pricing	Free	Paid
Price	—	$30/month
Free trial	No	0 days
Open source	No	No
Has API	Yes	Yes
Self-hosted option	Yes	No
Platforms	Python, TypeScript, Go, and Java	<cite index="30-1">Available through xAI API and integrated with launch partners including GitHub Copilot, Cursor, Cline, Roo Code, Kilo Code, opencode, and Windsurf</cite>
Languages	Python, TypeScript, Go, and Java	<cite index="1-23">TypeScript, Python, Java, Rust, C++, and Go</cite>
Released	2025-04	2025-08-28
Pros	Context is treated like source code with structured assembly of sessions, memory, tool outputs, and artifacts, automatic filtering of irrelevant events, summarization of older turns, lazy-loading of artifacts, and token usage tracking to keep agents fast, efficient, and reliable by default Multi-language support with Python, TypeScript, Go, and Java implementations Model-agnostic and compatible with other frameworks while optimized for Gemini Built-in development UI for testing, evaluating, debugging, and showcasing agents When deploying to Google Cloud, agents inherit managed infrastructure, built-in authentication, Cloud Trace observability, and enterprise-grade security without code changes	<cite index="2-25,2-26">Massive throughput of approximately 90-100 tokens per second, delivering dozens of tool calls and edits before you finish reading its initial plan in IDE integrations</cite> <cite index="1-13">Economical pricing at $0.20/1M input tokens and $1.50/1M output tokens</cite> <cite index="2-27,2-28,2-29">Visible reasoning traces that provide real-time, summarized view of its reasoning process, helping developers catch logic errors early</cite> <cite index="1-22">Prompt caching optimizations regularly achieving cache hit rates above 90% when used with launch partners</cite>
Cons	Optimized primarily for Google Cloud deployment and Gemini models, though model-agnostic capabilities exist Development version builds directly from latest code commits may contain experimental changes or bugs not present in stable release	<cite index="6-31,6-34">Potential gaps in training on specific frameworks; poor performance on Tailwind CSS v3 tasks, suggesting possible smaller model size limitations</cite> <cite index="6-36">Its reasoning model nature makes it unsuitable for interactive workflows requiring fast responses despite fast token throughput</cite>

Bottom line

Agent Development Kit (ADK) is free while Grok Code Fast 1 is paid. Choose based on which difference matters most for your workflow.
