Qwen: Qwen3.5 397B A17B

qwen/qwen3.5-397b-a17bModel weights

The Qwen3.5 series 397B-A17B native vision-language model is built on a hybrid architecture that integrates a linear attention mechanism with a sparse mixture-of-experts model, achieving higher inference efficiency. It delivers state-of-the-art performance comparable to leading-edge models across a wide range of tasks, including language understanding, logical reasoning, code generation, agent-based tasks, image understanding, video understanding, and graphical user interface (GUI) interactions. With its robust code-generation and agent capabilities, the model exhibits strong generalization across diverse agent.

Providers

RedPill routes this private model across verified providers with automatic fallbacks. Pricing is unified, so you pay the same price no matter which provider serves your request, while live metrics show first-token latency, speed, and uptime.

Release notes

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://tee.redpill.ai/v1",
  apiKey: process.env.REDPILL_API_KEY,
});

const response = await client.chat.completions.create({
  model: "qwen/qwen3.5-397b-a17b",
  messages: [{ role: "user", content: "Say hello." }],
});

Check privacy evidence

Follow the receipt from the gateway response to its verified session using four curl requests.

Check the gateway

Fetch the current TEE evidence and check that the keyset has not expired.

curl -fsS "https://tee.redpill.ai/v1/aci/attestation" \
  -H "Authorization: Bearer $REDPILL_API_KEY"

Output

{
  "api_version": "aci/1",
  "workload_keyset_digest": "sha256:4f3dc45e...",
  "attestation": { "workload_keyset": { "not_after": 1790498751, ... }, ... },
  ...
}

Send a private request

The response header contains the receipt ID, not the receipt itself.

curl -fsS -i "https://tee.redpill.ai/v1/chat/completions" \
  -H "Authorization: Bearer $REDPILL_API_KEY" --json '{"model":"qwen/qwen3.5-397b-a17b","messages":[{"role":"user","content":"Hello"}],"provider":{"aci_verified":true}}'

Output

HTTP/2 200
x-receipt-id: rcpt-e0eefe63b3673e2a5984951f
...

{
  "model": "qwen/qwen3.5-397b-a17b",
  ...
}

Inspect the receipt

Paste the x-receipt-id above and compare its keyset digest with step 1.

curl -fsS "https://tee.redpill.ai/v1/aci/receipts/REPLACE_WITH_RECEIPT_ID" \
  -H "Authorization: Bearer $REDPILL_API_KEY"

Output

{
  "api_version": "aci/1",
  "receipt_id": "rcpt-e0eefe63b3673e2a5984951f",
  "workload_keyset_digest": "sha256:4f3dc45e...",
  "event_log": [
    ...,
    { "type": "upstream.verified", "session_id": "63c5a08de14e5c5253e6fb29271151f40621beb83b552ccca65772772856053f", "result": "verified", "required": true },
    { "type": "response.returned", "body_hash": "sha256:..." }
  ],
  ...
}

Inspect the session

Copy session_id from the upstream.verified event above, then fetch that session.

curl -fsS "https://tee.redpill.ai/v1/aci/sessions/PASTE_SESSION_ID_FROM_RECEIPT" \
  -H "Authorization: Bearer $REDPILL_API_KEY"

Output

{
  "api_version": "aci/1",
  "upstream_name": "...",
  "verifier_id": "...",
  "claims": { "tee_attested": { "status": "asserted", ... }, ... },
  ...
}
