Cline, Kilo Code and Roo Code with the AI Stupid Level Smart Router

Pick the OpenAI Compatible provider in Cline, Kilo Code or Roo Code, paste the base URL and your aism_ key, and use a routing mode as the model ID: your own provider keys, no token markup, and the model that answered in every response.

Routing on benchmark results

A routing mode as the model name sends each request to the model placing highest on the relevant board — coding, reasoning or tool use — ranked on the average of its last five benchmark runs, never a single run. Statistically tied leaders are split by your tie-break preference, the cheaper measured cost per task by default. Drift-aware routing moves a model whose drift detector has fired for that skill behind every unflagged model.

Your own provider keys

You pay OpenAI, Anthropic, Google, DeepSeek, Moonshot AI (Kimi) or Z.ai (GLM) directly for tokens. Provider keys are encrypted at rest (AES-256-GCM) and never shown again.

No token markup

The router adds nothing to token prices. Free includes 1,000 routed requests a month, and only successful requests count.

The model that answered, every time

Every response carries X-AISM-Model and X-AISM-Reasoning: which model answered and why, including any fallback. If the chosen model fails before answering, the router tries your own fallback order, then up to 2 automatic fallbacks from different providers.

1. 01

   Create a router key

   Go to API keys, click Create key and copy it somewhere safe. The key starts with aism_ and is the one key for every tool you connect.

2. 02

   Add your provider keys

   Under Providers, add keys for OpenAI, Anthropic, Google, DeepSeek, Kimi or GLM. The more providers you add, the better the routing. You pay them directly for tokens; the router adds nothing to token prices, and provider keys are encrypted at rest (AES-256-GCM) and never shown again.

3. 03

   Choose the OpenAI Compatible provider

   Cline and Roo Code: Settings → “OpenAI Compatible” → paste the base URL and the key. Kilo Code: Settings → API Provider “OpenAI Compatible” → paste the base URL and the key.

   Cline / Kilo Code / RooSettings

   API Provider:  OpenAI Compatible
   Base URL:      https://aistupidlevel.info/v1
   API Key:       aism_your_key_here
   Model ID:      auto-coding   (or auto-tooling for long agent sessions)

4. 04

   Set the model ID

   auto-coding for code generation, debugging and refactoring, or auto-tooling for long agent sessions: the model best at calling tools correctly, scored on the tool-calling suite. The response header X-AISM-Model names the model that answered.

5. 05

   Alternative: the Anthropic provider

   Cline’s and Roo Code’s Anthropic provider can reach the router too, through the native Anthropic Messages passthrough at POST https://aistupidlevel.info/v1/messages (the base URL is the site root, as for Claude Code). There is no routing on that path: the request goes to Anthropic, with your Anthropic key, for the Claude model named.

• Tool calling works end to end: the router remembers each model’s own turn for 24 hours, so multi-step agent loops keep working, and a conversation stays on the model that started it.
• Prompt caching is on: agent loops resend the whole conversation every turn, and every provider can serve the part it has seen from its prompt cache at a fraction of the input price. Cached tokens are reported in usage.prompt_tokens_details.cached_tokens.
• Model dropdowns are filled from GET /v1/models, which needs a valid aism_ key.
• Text only: a request with images, audio or files gets a 400 unsupported_content.
• Windsurf: Cascade is locked to Codeium’s backend. Install Roo Code or Cline inside Windsurf instead.

401 invalid_api_key

Missing or invalid aism_ key. Check the key is correct and not revoked, and that the tool sends it as Authorization: Bearer aism_…. If a field insists on an sk- prefix, sk-aism_… is accepted: the prefix is stripped automatically. A key that had an expiry date and passed it gets 401 expired_api_key, and the message says when.

400 model_not_found

An unknown auto-* name is a 400 that lists the valid routing modes. For a real model id, check the spelling: direct pin routing infers the provider from the model name prefix, and GET /v1/models lists every id you can use.

No models in the dropdown

The tool fills its list from GET /v1/models, which requires a valid aism_ key. Check that the key and the base URL https://aistupidlevel.info/v1 are both in place.

400 provider_key_rejected or no_provider_keys

Your provider key is missing or was refused. Add or update it under Providers, re-check it on the provider’s dashboard, and make sure it has active credits and the right permissions.

Streaming

Set stream: true. Text arrives as the model writes it (X-AISM-Streaming-Mode: native); tool calls arrive in one chunk each once the model has finished them, then the finish reason, then usage if you set stream_options.include_usage. If the chosen model fails before sending anything, or its provider sends nothing for 120 seconds, the next fallback is tried.

400 unsupported_content

The router routes text only, on purpose: it picks a model from benchmark results for coding, reasoning and tool use, and none of those measure image, audio or file understanding. Send such requests to the provider directly.

429 allowance_exhausted

This month’s requests are used up and you have no prepaid credits. Credits top up the allowance; moving up a plan is the cheaper way to buy regular volume.
