Stealth Alpha

lx1-union-alphaCodingLive in the catalogFree

Stealth Alpha is a multimodal model for research, coding, and long agent loops. It takes text and images, calls tools, and holds a 262K-token window with up to 131K tokens of output. It is free on Layer X1 for a limited time. You need a plan or leftover credits on the account to call it — an empty Free account should upgrade or load credits first. Ask for it by name; it is not on the automatic route.

Free for a limited time. A plan or leftover credits on the account is enough to call it. An empty Free account should upgrade or load credits first.

03Coding and agent workflows by explicit model id

Capabilities

Tool callingYes

Strict, schema-faithful tool calls, enforced by the engine on every request — safe to build an agent loop on.

ReasoningYes

Thinks before it answers. Budget max_tokens generously — hidden reasoning counts against it.

VisionYes

Reads images — screenshots, diagrams, and UI states — inline in the conversation.

Behind the endpoint[02/03]

One endpoint. Served by our engine.

Stealth Alpha is served through the Layer X1 engine — zero-downtime serving is the design target, not a status-page apology. You request it by name; everything else is our problem.

Call it by name

curl https://api.layerx1.in/v1/messages \
  -H "x-api-key: lx1_your_key" \
  -H "content-type: application/json" \
  -d '{
    "model": "lx1-union-alpha",
    "max_tokens": 1024,
    "messages": [{ "role": "user", "content": "Hello" }]
  }'

OpenAI-style clients work too — send the same model name to /v1/chat/completions with a Bearer key. See the docs for both dialects.

Your agent stays the same.
Its inference gets better.
