OpenAI: GPT OSS 20B
gpt-oss-20b is an open-weight 21B parameter model released by OpenAI under the Apache 2.0 license. It uses a Mixture-of-Experts (MoE) architecture with 3.6B active parameters per forward pass, optimized for lower-latency inference and deployability on consumer or single-GPU hardware. The model is trained in OpenAI’s Harmony response format and supports reasoning level configuration, fine-tuning, and agentic capabilities including function calling, tool use, and structured outputs.

})Confidential GPU-TEE responses carry two proof layers you can check yourself: a nonce-bound attestation report for the gateway, and a signed receipt that binds your request and response to an attested upstream session.
# 1. Attest the gateway (nonce-bound, proves which TEE workload serves you)
NONCE="$(openssl rand -hex 16)"
curl -s "https://api.redpill.ai/v1/aci/attestation?nonce=$NONCE" \
-H "Authorization: Bearer $REDPILL_API_KEY" -o report.json
# 2. Call the model and capture the x-receipt-id response header
curl -s "https://api.redpill.ai/v1/chat/completions" -D headers.txt \

RECEIPT_ID="$(grep -i ^x-receipt-id headers.txt | tr -d '\r' | awk '{print $2}')"
# 3. Fetch the signed receipt, then follow it to the attested session
curl -s "https://api.redpill.ai/v1/aci/receipts/$RECEIPT_ID" \
