SETTINGS

Fuel Computer

Chats are E2EE encrypted between this browser and NEAR’s model environment; Cloudflare relays ciphertext.

Appearance
Enable Web SearchWhile enabled, prompts and results are visible to Fuel Computer and Parallel. Model context and replies are then encrypted to NEAR.
Use local chat contextShares up to three relevant excerpts from other local chats with NEAR after browser encryption.
Anonymous analyticsShares broad app health and usage such as success/error category, duration range, device class, and country. The analytics dataset never includes chats, prompts, replies, searches, wallet addresses, keys, ciphertext, IP addresses, raw errors, or user identifiers.

PRIVACY & ATTESTATION

How private inference works

Attestation is checked before your first encrypted request.

Checked by this browser

  • Fresh 32-byte challenge and selected model identity
  • Intel TDX quote, Intel collateral, validity and TCB status using browser WASM
  • Verified quote binding to the nonce, Ed25519 model key and attested TLS fingerprint
  • Compose-manifest consistency with mr_config_id when supplied
  • Pinned selected model: z-ai/glm-5.3-flash

Encryption and identities

The browser converts the model’s advertised Ed25519 identity to X25519, creates an ephemeral client key, derives a key with HKDF-SHA256 using the ed25519_encryption context, and encrypts with XChaCha20-Poly1305. Browser private keys remain in memory.

Data boundary

For normal chat, plaintext exists in this browser and inside NEAR’s model environment; Cloudflare relays ciphertext and operational metadata. When Web Search is enabled, opted-in queries and results are visible to Cloudflare and Parallel before the browser encrypts source context to NEAR. Conversation history is stored only in this browser.

Not independently verified yet

The browser does not yet verify NVIDIA NRAS’s signing root/verdict, whether attested deployment measurements are on an authoritative approved allowlist, model-key rotation authority, encrypted response signatures, or the live same-connection TLS SPKI. Compose consistency proves that a manifest matches the verified quote; it does not prove that the deployment is approved. Evidence is relayed by Cloudflare because NEAR’s direct endpoint does not permit browser CORS, while Intel collateral is independently verified in-browser.

OPTIONAL DIAGNOSTICS

Help improve Computer?

Report this issue using only a broad failure category, duration range, device class, and Cloudflare-derived country. The analytics dataset never includes chat content, raw error details, searches, addresses, keys, ciphertext, IP addresses, or user identifiers.
