Hy4 preview vs Microsoft Bing Image Creator: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Hy4 preview and Microsoft Bing Image Creator — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
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.
Microsoft Bing Image Creator
Microsoft
Web-based, free generator that turns text prompts into images and short videos using DALL·E and Sora.
Key features
- Text-to-Image Generation: Converts natural-language prompts into detailed images using DALL·E as the image generation backend, enabling users to produce visuals from simple descriptions.
- Text-to-Video Generation: Creates short, engaging videos from textual prompts using Sora, allowing rapid production of motion content alongside still images.
- Fast Output: Optimized for quick turnaround—produces visuals in seconds so users can iterate rapidly on concepts and prompts.
- Web-Based Interface: Accessible via bing.com/images/create with no local installation required, providing a simple prompt box and generation workflow through a browser.
- Multiple Visual Outputs: Generates completed renderings from a single prompt to help users compare variations and select the best result (multiple outputs per request depending on service limits).
- Built-in Moderation & Policies: Operates under Microsoft content and usage policies to filter disallowed content and guide safe generation (subject to Microsoft terms).
- Integration with Microsoft Ecosystem: Positioned to work alongside Bing services and Microsoft design tools for streamlined access within Microsoft products and workflows.
- Text-to-image generation using models based on DALL-E (including references to DALL-E 3)
- Text-to-video generation (Bing Video Creator) powered by Sora and related models
- Fast, web-based generation via bing.com/images/create
- Supports batch generation workflows via third-party automation (Selenium, Colab, Google Sheets integrations)
- Community-maintained CLI and library wrappers (Python, Node.js) for programmatic use (unofficial)
- Requires browser session authentication for unofficial programmatic access (notably the '_U' cookie used by several wrappers)
- Works with browser automation drivers (e.g., msedgedriver) and standard language runtimes for community tools
- No officially documented public API surfaced in provided content; reverse-engineered APIs exist in open-source projects
Best for
- Marketing Creative Production: Quickly generate campaign visuals and social media imagery from concise creative briefs for rapid iteration and A/B testing.
- Content Illustration: Produce custom images to illustrate blog posts, articles, or documentation without commissioning external artwork.
- Concept Art & Ideation: Rapidly visualize concepts and mood ideas for games, films, or product designs during early-stage creative exploration.
- Prototype Visual Assets: Create mockups and visual assets for UI/UX prototypes and product demos to speed up design reviews.
- Short Video Storyboarding: Use Bing Video Creator to produce short animated sequences or visual storyboards from textual scene descriptions for pre-production.
- Educational & Presentation Materials: Generate tailored imagery to enhance slides, lesson plans, and instructional content without sourcing stock assets.
- Rapid creation of marketing and social media images from natural language prompts
- Generating creative assets, concept art, and illustrations for design workflows
- Batch image generation pipelines via automation for content libraries (using Selenium/Colab/community scripts)
- Prototyping visuals for product mockups and presentations
- Generating short, stylized videos for social posts or concept visualization
