Hy4 preview vs Ideogram: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Hy4 preview and Ideogram — 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.
Ideogram
Ideogram
Text-to-image model focused on accurate text rendering, layout and typography for posters, logos, and inpainting.
Key features
- Prompt-Adherent Rendering: Generates images that closely respect the input text prompt, with emphasis on accurate textual content and placement inside images, reducing common text-errors in other models.
- High-Fidelity Typography and Layout: Strong layout and typographic control for posters, logos, banners, and marketing assets, enabling consistent and readable on-image text across outputs.
- Style Reference Support: Accepts style reference images to preserve visual identity and maintain consistent styling across a series of generated outputs.
- Inpainting and Edit Endpoints: Provides inpainting/remix/edit capabilities (documented in community examples and Replicate demos) to remove, replace, or modify specific regions of an image.
- API & Integration Ecosystem: Accessible via third-party platforms (e.g., Replicate) and community MCP servers (fal.ai implementations), with community wrappers and example repositories for Node.js and Python.
- Queue/Webhook Workflows: Community MCP server implementations show support for queue-based generation and webhook callbacks for asynchronous/production pipelines.
- Text-to-image generation with strong prompt adherence and accurate text rendering
- Inpainting / mask-based image editing
- Style reference support (use example images to preserve visual identity)
- Advanced style and layout control parameters
- Hosted API endpoints (versions observed: v2 and v3) accessible via platforms like Replicate and fal.ai
- Community MCP server implementations for fal-ai/ideogram/v3
- Unofficial SDKs and wrappers (Python packages, Node.js examples) using API keys and environment variables
- Queue-based generation and webhook support for asynchronous workflows
Best for
- Poster and Flyer Creation: Generate marketing posters with precise headline and body text placement, ensuring typography and layout match brand requirements.
- Logo and Branding Assets: Produce logo concepts and brand visuals where embedded text and typography must remain sharp and accurate.
- Inpainting for Photo Edits: Remove or replace objects and text in photos or modify parts of an image while preserving surrounding composition using inpainting endpoints.
- Automated Marketing Variations: Create many on-brand ad or banner variations with different copy and layouts programmatically via API integration.
- Design Prototyping: Rapidly generate mockups and visual concepts that include exact copy and typographic treatments for client reviews.
- Pipeline Integration: Integrate queued image generation into content workflows using MCP servers or Replicate endpoints with webhook notifications for async processing.
- Generating marketing materials, posters, and banners with accurate text and typography
- Logo and branding explorations where precise text rendering is required
- Image editing and object removal using inpainting
- Producing stylized product mockups using style reference images
- Batch generation pipelines integrated via webhooks or MCP servers
