modbender Smart Router — Intelligent Model Router
Route tasks to the best model automatically, via any OpenAI-compatible API.
Author: whatevername2023@proton.me
Setup
Models and provider are configured in models.json. Set two environment variables:
SMART_ROUTER_BASE_URL— OpenAI-compatible API base URL (e.g.https://api.openai.com/v1)SMART_ROUTER_API_KEY— API key for the provider
Edit models.json to customize categories, models, and defaults for your provider.
@ Alias Shortcuts
Prefix a message with @alias to skip auto-classification and call a specific model directly.
Format: @alias your question or prompt here

Aliases are case-insensitive. If no alias matches, attempt fuzzy match on model name/ID. If still no match, prompt the user.
Auto-Classification Rules
When no @alias is specified, classify the task automatically:
| Category | Trigger |
|---|---|
vision |
User sends image/URL, asks to analyze, describe, OCR, understand image content |
image_gen |
Requests to draw, generate image, design poster, create illustration |
video_gen |
Requests to generate video, animation, text-to-video, image-to-video |
audio |
Requests for music generation, TTS, sound effects |
reasoning |
Complex math, logic puzzles, proofs, deep analysis, long-chain reasoning |
code |
Code generation, debugging, refactoring, review (when external model needed) |
general |
Everyday chat, translation, summarization, writing, Q&A |
Usage
1. Read Model Config
cat "$(dirname "$0")/../models.json"
2. Select Model
- Determine
categorybased on classification rules above - Use the first model with
"default": truein each category - If user specifies a model via
@alias, use that model directly - For cost-sensitive tasks, pick a smaller model in the same category
3. Call Model
Chat (vision / reasoning / code / general)
scripts/call-model.sh --model "MODEL_ID" --prompt "user request" --type chat
With image (vision):
scripts/call-model.sh --model "MODEL_ID" --prompt "request" --type chat --image "IMAGE_URL"
Image Generation
scripts/call-model.sh --model "MODEL_ID" --prompt "image description" --type image
Async Tasks (video / audio)
scripts/call-model.sh --model "MODEL_ID" --prompt "task description" --type async
TTS
scripts/call-model.sh --model "MODEL_ID" --prompt "text to speak" --type tts --voice alloy
4. Return Results
- Chat: return the model's text reply directly
- Image: return the generated image URL in markdown format
- Video/Audio: return task status and result URL
Model Recommendations
- Vision:
qwen3-vl-235b-a22b-instruct(strongest visual understanding) - Image gen:
google/imagen-4-ultra(highest quality) - Video:
sora-2-pro-all(best results) - Music:
suno_music/ TTS:tts-1-hdorgemini-2.5-pro-preview-tts - Reasoning:
o3(strongest reasoning) - Code:
gpt-5.1-codex-max - General:
claude-opus-4-6
Fallback
If a model call fails, automatically fall back to the next model in the same category.
Customization
Edit models.json to:
- Add/remove models in any category
- Change default models
- Add new categories
- Update aliases in SKILL.md to match
The scripts/sync-models.sh script lists all available models from your provider to help discover new ones.
