SYN Aliases (Recommended)
Use a syn: alias to automatically route to the latest recommended model for a given category. These aliases are always up-to-date and are the easiest way to ensure you're using the best available model.
| Alias | Resolves To | Category |
|---|---|---|
syn:large:text | hf:zai-org/GLM-5.1 | Large text model |
syn:small:text | hf:zai-org/GLM-4.7-Flash | Small text model |
syn:large:vision | hf:moonshotai/Kimi-K2.6 | Large vision model |
syn:small:vision | hf:Qwen/Qwen3.6-27B | Small vision model |
Example:
curl -X POST https://api.synthetic.new/v1/chat/completions \
-H "Authorization: Bearer ${SYNTHETIC_API_KEY}" \
-H "Content-Type: application/json" \
-d '{
"model": "syn:large:text",
"messages": [{"role": "user", "content": "Hello!"}]
}'Always-On Models
These models are included in all subscriptions. Per-token pricing is also available with usage-based billing.
Pinning to models may result in errors over time
Pinning to specific model names risks 404 errors when we rotate older models out. Use a syn: alias instead for automatic routing to the latest recommended model.
