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.

TRAE SOLO

Trae / Trae-AI

Freemium

SOLO is TRAE's autonomous coding mode that runs dedicated agent components (SOLO Code/Builder) inside the TRAE IDE to generate and modify code via natural language.

Key features

  • SOLO Mode: An autonomous agent mode inside TRAE that runs dedicated components (SOLO Code, SOLO Coder, SOLO Builder) to generate, modify, and manage codebases via natural-language instructions.
  • Downloadable Agent Components: SOLO exposes modular components (e.g., SOLO Code) that users can instantiate or download into their TRAE installation to enable isolated agent sessions.
  • Natural-Language Coding: Accepts human prompts and system prompts (community or custom) to perform complex code generation, refactors, and multi-file changes across projects.
  • Integration with TRAE Workflow: Works natively inside the TRAE IDE, leveraging TRAE memories, prompts, and existing workspace context to produce context-aware code edits and actions.
  • Deployment & Tooling Hooks: Integrates with common developer tooling and deployment flows (users have reported Vercel workflow integrations and deployment-related operations) to automate end-to-end tasks.
  • Subscription-Gated Access Control: SOLO features are accessed through TRAE's paid tier (TRAE PRO) and require users to enable/instantiate the SOLO modules within their account/environment.
  • Community Prompts & Builders: Supports community-contributed prompts and a SOLO Builder concept for constructing system prompts or agent behaviors tailored to specific development tasks.
  • Agent Session Management: Runs isolated sessions intended for single-agent workflows (Solo) to let the agent focus on a project or task without interfering with other IDE operations.
  • Solo Mode (SOLO Code / SOLO Builder): autonomous single-agent coding workflows for scaffolding and building projects
  • Natural-language code assistance integrated into the editor (conversational/code transform features)
  • Integration with VS Code ecosystem (install hooks and extensions referenced for Trae) and a desktop Electron application
  • Community prompts/memories system to store/share prompts and templates
  • Companion agent repositories (trae-agent and related GitHub projects) for integrations and backend agent functionality
  • Cross-component architecture: desktop app (Electron), VS Code extension hooks, and browser extension install points (Chrome / Edge button referenced)
  • Project management and session persistence (issues indicate project/workspace handling, version/build metadata)

Best for

  • Autonomous Feature Implementation: Provide a natural-language description of a new feature and have SOLO generate the code, update multiple files, and create tests across the repository.
  • Large-Scale Refactoring: Instruct SOLO to refactor or modernize legacy code (rename symbols, update APIs, restructure modules) while leveraging workspace context and automated edits.
  • Prompt-Driven Prototyping: Rapidly prototype components or microservices by describing desired behavior; SOLO generates runnable scaffolding and connects build/deploy steps.
  • Automated Deployments & CI Tasks: Use SOLO to configure or trigger deployment flows (e.g., Vercel) and automation tasks from inside the TRAE IDE as part of a development-to-deploy workflow.
  • Creating Custom Agent Workflows: Build and iterate custom SOLO Builder prompts and system prompts to tailor agent behavior for code reviews, security scans, or onboarding tasks.
  • AI Pair-Programming Sessions: Run SOLO in an isolated session to act as a coding partner—implementing suggestions, generating alternative implementations, and producing test cases.
  • Autonomous project scaffolding and builder workflows (generate a complete project or feature from prompts)
  • Interactive natural-language code generation, refactoring, and completion within an IDE
  • Creating and sharing community prompts, templates, and agent configurations (memories/agents)
  • Embedding Trae capabilities into developer toolchains via VS Code integration or companion agent services
  • Rapid prototyping and debugging with model-driven assistance and conversational context
