One prompt.
The best model for the job.
Aridel classifies every prompt and sends it to the right frontier model — Claude, GPT, Gemini, Kimi, DeepSeek, and more. Pay pennies for the easy stuff. Reach for the smartest model only when you actually need it.
Smart routing
An embedding-based classifier reads each prompt and picks the model with the best price/quality fit. Easy questions go to cheap, fast models. Hard ones get the heavyweights.
39 models, one thread
GPT-5 family, Claude 4.x (Opus, Sonnet, Haiku), Gemini 2.5 & 3, plus the strongest open-source models — DeepSeek, Kimi K2, Qwen 3, MiniMax, GLM, Amazon Nova — behind one chat UI and one OpenAI-compatible API.
Stop overpaying
Most prompts don't need a top-tier model. Routing trims the bill on the long tail of easy queries — without you having to think about which model to pick.
How it works
Three steps, no model picking, no per-provider accounts.
You write a prompt
Same flow as ChatGPT or Claude — one box, one stream. Attach files, toggle web search, keep your conversation history.
Aridel classifies it
A lightweight classifier embeds the prompt, estimates difficulty and domain, then selects the model that gives you the best answer per dollar.
Streamed answer, every time
The chosen model streams back token-by-token. We log which model was picked and why, so you can audit the routing decision later in Insights.
Also an API you can build on
The web app runs on the exact same public API you get. It's
OpenAI-compatible — point your existing client at
api.aridel.ai, set model="auto", and
routing is on. Or pip install aridel:
from aridel import Aridel
client = Aridel(api_key="aridel_live_...")
response = client.chat.completions.create(
model="auto", # let the router pick
messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)
print(response.routing) # which model, and whyRouting as a service
POST /v1/route returns the routing decision —
chosen model, complexity, confidence, cost estimate — without
calling any model. Batch hundreds of prompts in one call and
drive your own stack with it.
Real workloads
Tool calls, vision, file inputs, pre-flight token counting, per-request model pools, and async batch jobs on supported providers' discounted batch endpoints.
Insights & audit logs
Every routed call feeds your Insights dashboard — model mix,
savings estimates, quality lift. Opt-in audit logging keeps a
write-once record per request, readable via
/v1/audit-logs.
