Mouse-1

Mouse

Paid

Mouse-1 is a fast, low-cost decision model that plugs into agent harnesses to handle routing, gating and verification.

Key features

  • Decision Layer for Agents: Takes agent state and options and returns probabilities so the harness can route, gate and verify.
  • About 100 ms Latency: Answers faster than a chat model's first token.
  • Batch Decisions: One request answers up to 128 questions.
  • Prompt-Injection Resistance: Chooses only from supplied options; planted instructions changed 0% of decisions in vendor tests.
  • Zero Data Retention: Requests are scored and dropped, never stored or used for training.
  • Image and Document Classification: Handles content moderation, document routing and browser-state detection.

Best for

  • Agent Routing: Deciding which model or tool an agent should use next.
  • Action Gating: Approving or blocking risky agent actions cheaply.
  • Content Moderation: Classifying images or text as safe or unsafe.
  • Document Routing: Sending invoices, contracts and IDs to the right workflow.
  • Browser Agents: Detecting screen state such as login required or error.
  • Cost Reduction: Offloading small decisions from expensive frontier models.

Stable Diffusion Web UI

AUTOMATIC1111

Free

A Gradio-based local web interface for running, managing, and extending Stable Diffusion models with extensive scripts and platform support.

Key features

  • Gradio Web Interface: A browser-based UI built on Gradio for interactive image generation and editing, exposing common parameters and visual previews to users.
  • Cross-Platform Launchers: Includes platform-specific launch and helper scripts (webui-user.bat, webui.sh, update.bat) and documented installation steps for Windows, Linux, and Apple Silicon systems.
  • Model and Checkpoint Management: Clear model placement and management workflow (e.g., models/Stable-diffusion folder), support for multiple checkpoints and configuration YAMLs to run different Stable Diffusion variants.
  • Custom Scripts & Extensions: Official wiki and community resources for custom scripts and extensions, enabling added functionality, experimental features, and plugin-style enhancements.
  • Integration with Restoration Tools: Examples and support for integrating tools like GFPGAN for face restoration and other post-processing/upscaling utilities.
  • Multi-GPU and Hardware Guidance: Documentation and installation guidance for NVIDIA (recommended), AMD GPUs, and Apple Silicon to optimize inference and compatibility.
  • Image Generation Modes: Provides common generation workflows (e.g., txt2img and img2img) with prebuilt screenshots and examples in the repository to illustrate workflows and parameters.
  • Community-driven Forks & Optimization Layers: Ecosystem of forks (Forge, reForge) and community projects that add resource management, inference speedups, and experimental APIs on top of the core web UI.
  • Gradio-based browser GUI for Stable Diffusion (txt2img and other interfaces referenced)
  • Local model management: place checkpoints/models in models/Stable-diffusion folder
  • Platform launch scripts: webui-user.bat (Windows), webui.sh/webui.py (Linux/macOS), WSL2 environment YAML
  • Automatic virtual environment creation and dependency installation (venv) on launch
  • Explicit installation guidance and scripts for NVidia (recommended), AMD GPUs and Apple Silicon
  • Support for community extensions and custom scripts (wiki pages for scripts/extensions)
  • Support for different Stable Diffusion model versions and configs (v1, v2 depth model note)
  • High-resolution fix handling and hooks for sampling (extension/script API within WebUI)
  • Works with online services such as Google Colab for remote/quick setup
  • Requirements and environment files included: requirements.txt, requirements_npu.txt, environment-wsl2.yaml, requirements_versions.txt

Best for

  • Local Image Generation: Run Stable Diffusion locally through a web browser to generate images from text prompts without relying on external hosted services.
  • Prompt Engineering and Iteration: Rapidly prototype and refine prompts using the interactive UI and visual previews to achieve desired outputs.
  • Batch and Automated Renders: Use built-in batching and launch scripts to produce large sets of images or run parameter sweeps for dataset creation or experimentation.
  • Model Testing and Comparison: Load multiple checkpoints and configurations to compare model outputs, test new checkpoints, or evaluate fine-tuned models.
  • Image Editing and Restoration: Perform image-to-image edits, inpainting, and integrate face-restoration/upscaling tools (e.g., GFPGAN) for higher-quality results.
  • Extension Development and Experimentation: Develop and test custom scripts or extensions via the project's wiki and community repositories (Forge/reForge) to prototype new sampler or optimization features.
  • Cross-hardware Deployment: Deploy and run Stable Diffusion on a variety of local hardware setups (NVIDIA, AMD, Apple Silicon) using documented installation procedures.
  • Local image generation and experimentation with Stable Diffusion models via GUI
  • Rapid prototyping and visual parameter tuning (prompt weighting, sampler settings)
  • Research and development of custom sampling scripts and model extensions
  • Resource optimization and experimental features via community 'Forge' forks
  • Running Stable Diffusion on Apple Silicon, NVidia/AMD GPUs, WSL2 or via Colab
