lfx-aistupidlevel

Stop choosing AI models manually. Let live benchmarks choose the best model for coding, reasoning, or agent tasks—using your own provider keys, with zero token markup.

This package adds the AI Stupid Level Smart Router to Langflow in two forms: a model provider for the Language Model and Agent components, and an AI Stupid Level component that shows which model answered.

Install

pip install lfx-aistupidlevel

Install it in the same Python environment as Langflow (uv pip install lfx-aistupidlevel works too), then restart Langflow. Langflow loads installed extensions when it starts, so there is nothing to enable. It needs Langflow 1.12 or later.

You also need a router key (aism_...) from https://aistupidlevel.info/router/keys, and your provider keys (OpenAI, Anthropic, Google, DeepSeek, Kimi, GLM) added to your AI Stupid Level account.

Where it appears in Langflow

• Settings → Model Providers → AI Stupid Level. Paste the router key and save; Langflow checks it against the router. Instead, you can set AISTUPIDLEVEL_API_KEY in Langflow's environment. Five routing modes are enabled by default (auto-coding, auto-tooling, auto-reasoning, auto-best, auto-value). You can switch on the other modes and the pinnable models in the same pane.
• Language Model and Agent components. Choose an AI Stupid Level mode, such as auto-coding, in the model picker. Every mode supports tool calling, so all of them appear in the Agent's picker too.
• AI Stupid Level component, in the components sidebar. It is a chat model with a Model dropdown, which defaults to auto-coding; click refresh to load every mode and model from the router. After each answer, the Chat Output message names the model that answered (the flow editor's chat shows it beside the sender), and the component's Routing log gives the router's reason for choosing it. Its Language Model output can drive an Agent. Leave its key field empty to use the key saved in Model Providers (or AISTUPIDLEVEL_API_KEY); it also accepts ASL_ROUTER_KEY, the variable the other AI Stupid Level SDKs read.

Routing modes

A model id such as claude-opus-5-5 instead of a mode pins that model. Langflow reads the list from the router's GET /v1/models. If the router can't be reached, it falls back to the routing modes. The modes are described at https://aistupidlevel.info/router/docs#strategies.

Your keys, zero markup

The router calls the chosen model with your own provider key, so the provider bills you directly, and AI Stupid Level adds nothing to token prices. It routes text and tool calls; image input is not supported.
