Google AI Studio vs Hy4 preview: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Google AI Studio and Hy4 preview — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Google AI Studio
Web-based platform from Google to build, fine-tune, prototype and deploy applications using Gemini and related multimodal models.
Key features
- Prompt-to-Production Workflow: Integrated UI and tooling to iterate on prompts, build prototype applets and move prototypes toward production-ready deployments with Gemini models.
- Multimodal Model Access: Native access to Gemini model capabilities including text, image, audio and video modalities and the Live API (audio/video streaming) for interactive multimodal experiences.
- Fine-Tuning and Custom Models: Ability to fine-tune base models for custom tasks and datasets (community reports indicate free fine-tuning options within Studio), enabling tailored performance for domain-specific use cases.
- Starter Applets and Local Development: Official starter applets (React-based) that run inside AI Studio and can be run locally by inserting a Gemini API key, accelerating building of map, video, and interactive demos.
- Function Calling and Tooling Integration: Support for function calling, code execution, and integrated Google search grounding to let models call external APIs (e.g., Maps Embed) and execute external actions.
- Media Generation & Plugins: Access to media generation (Imagen, Veo) and model features that produce or manipulate images, video, and other media formats for richer applications.
- Vertex AI Compatibility: Compatibility with Google Cloud Vertex AI for enterprise developers who need managed infrastructure, scaling, and enterprise-grade deployment options.
- Examples, Cookbook & SDKs: Official example repositories and SDK guides (Gemini cookbook) to demonstrate quickstarts, LiveAPI usage, and multi-feature integrations for developers.
- Interactive web IDE for prompting and testing Gemini models
- Fine-tuning and customization of base models (free fine-tuning options mentioned)
- Starter applets and templates (React-based) that run inside AI Studio
- Integration with Gemini API and Vertex AI APIs for training and deployment
- Support for function calling / invoking external APIs (e.g., Maps Embed API)
- Demonstrations of 2D and 3D spatial understanding and reasoning
- Local development workflow using environment (.env) files with Gemini API key
- Tooling for building AI agents and multi-component applications
- Works with regional Vertex AI deployments (EU / UK compatibility noted)
Best for
- Prompt engineering and rapid prototyping: Iteratively design and test prompts and conversational flows for Gemini, then package prototypes into small applets or demos.
- Custom fine-tuned models for domain tasks: Fine-tune Gemini models on proprietary datasets (text, images) to improve performance on customer support, legal summarization, or specialized classification.
- Multimodal interactive apps: Build applications that combine video/audio/image understanding with text reasoning (e.g., video event exploration, spatial mapping with embedded maps) using starter applets and LiveAPI.
- Tool-enabled assistants: Create assistants that execute functions, call external APIs (like Maps Embed), run code, and ground answers with Google search or other tools for accurate, actionable outputs.
- Media generation and content creation: Generate and edit images or short video snippets using integrated media models (Imagen, Veo) for marketing, creative workflows, or automated asset creation.
- Enterprise deployment via Vertex AI: Move prototypes from Studio into managed, scalable production deployments on Google Cloud Vertex AI for enterprise-grade reliability and compliance.
- Rapid prototyping of LLM-powered apps and agents
- Fine-tuning base models for domain-specific tasks
- Building spatially-aware applications (2D/3D reasoning, video event exploration)
- Integrating LLMs with external services (maps, embeds, other APIs) via function calling
- Educational tutorials and starter projects for developer onboarding
- Local development and testing of Gemini-powered frontend apps
Hy4 preview
Tencent
Tencent's open-weight Hy4 preview, a 770B-parameter Mixture-of-Experts model with 49B active parameters and a 1M-token context window.
Key features
- 770B Mixture-of-Experts Architecture: Holds 770 billion total parameters while activating only 49 billion per token, so capacity scales without proportional inference cost.
- 1M-Token Context Window: Accepts inputs exceeding one million tokens, allowing whole codebases, long document sets or extended agent traces in a single prompt.
- Apache 2.0 Open Weights: Released under a permissive licence that allows commercial use, modification and redistribution with no separate agreement.
- Productivity Task Focus: Tuned for real-world coding, office work and scientific research rather than narrow benchmark optimisation.
- Multi-Product Availability: Accessible globally through Tencent's WorkBuddy, CodeBuddy, Yuanbao and ima applications in addition to the raw weights.
- API Access via TokenHub and OpenRouter: Can be called through Tencent Cloud TokenHub or OpenRouter for teams that prefer hosted inference over self-hosting.
Best for
- Whole-Repository Code Work: Load an entire codebase into the million-token context to reason about refactors and cross-file dependencies at once.
- Long-Horizon Agent Tasks: Drive multi-step agent workflows where the full history of tool calls and intermediate results must stay in context.
- Self-Hosted Deployment: Run a frontier-scale open-weight model on private infrastructure where data cannot leave the organisation.
- Scientific Literature Analysis: Ingest large collections of papers or experimental logs and synthesise findings without chunking the input.
- Office Document Processing: Summarise, draft and restructure long reports, contracts and spreadsheets in enterprise workflows.
- Commercial Fine-Tuning: Adapt the weights for a proprietary product under the Apache 2.0 licence without negotiating a model licence.
