Deterministic AST Inference & Multi-Model Routing

Vidura AI dynamically arbitrates generative requests across frontier reasoning engines (Claude 3.7 Sonnet, DeepSeek R1, GPT-4o, and on-prem Llama 3) through a deterministic, client-vaulted AST synthesis pipeline designed to eliminate runtime parsing failures.

Zero Telemetry & Client-Side AES-256 VaultingSEC-HARDENED

Provider API secrets are never transmitted in plaintext to our routing mesh. All payload parameters and custom endpoint credentials undergo client-side envelope encryption via WebCrypto AES-GCM before socket negotiation. Memory heaps within edge workers are wiped using zero-fill on socket termination.

01.Pre-Inference AST Synthesis Lifecycle

Formal Logic Verification

Standard LLM APIs generate unconstrained raw character streams that frequently violate grammar constraints during nested JSX or TypeScript evaluation. Vidura enforces a synchronous compiler state machine:

Inference Stream Vector Pipeline

Babel Rust CoreLatency Overhead: <1.8ms

STAGE 01

Prompt Intake

Client signs payload with ephemeral hash; token rate limits audited.

STAGE 02

Smart Arbiter

Evaluates model latency budgets and routes to Sonnet, R1, or Ollama.

STAGE 03

AST Parse Guard

Live token stream runs through incremental TS grammar tree validation.

STAGE 04

Execution Node

Validated component mounts in sub-10ms isolate sandbox environment.

02.Client SDK Integration

NPM: @vidura/sdk@3.5.2

Initialize the Vidura client on the edge runtime or browser worker. Provide local AES keys to keep telemetry locked strictly to your own hardware domain.

client.worker.ts

import { ViduraClient, StreamingASTParser } from '@vidura/sdk';

// 1. Instantiate the Zero-Telemetry Edge Client
const client = new ViduraClient({
  apiKey: process.env.VIDURA_CLIENT_TOKEN,
  mode: 'deterministic-ast',
  vaultConfig: {
    algorithm: 'AES-GCM',
    clientKeyId: 'vk_stage_prod_8902',
    enforceLocalSecrets: true
  },
  router: {
    primaryEngine: 'anthropic:claude-3-7-sonnet',
    failoverEngine: 'deepseek:r1-distill-llama',
    divergenceThresholdMs: 450
  }
});

// 2. Execute Stream with Live Syntax Tree Guard
const stream = await client.synthesizeStream({
  prompt: 'Generate a high-concurrency event subscriber using React 19 Actions',
  parser: StreamingASTParser.TSX,
  targetSpec: 'nextjs-15-app-router',
  onToken: (token, snapshotAST) => {
    // Instant snapshot validity check before DOM mounting
    if (!snapshotAST.hasUnclosedNodes) {
      console.log('[AST Valid Chunk]', token.content);
    }
  }
});

03.Execution Parameters & Typings

Schema: ViduraRoutingConfig

The multi-model router evaluates request parameters synchronously before opening upstream provider sockets. All properties adhere strictly to JSON-Schema Draft 7.

Parameter	Type	Default	Description
primaryEngine	String (Enum)	'claude-3-7'	Target frontier model identifier. Automatically resolves upstream credentials from the client-side AES vault.
failoverEngine	String (Enum) \| null	'deepseek-r1'	Secondary fallback provider invoked if latency exceeds `divergenceThresholdMs` or HTTP 429 occurs.
parser	ASTParserSpec	StreamingAST.TSX	Grammar parser applied to streaming chunks. Options include `TSX`, `RustAST`, and `PyBytecode`.
vaultConfig.enforceLocal	Boolean	true	Guarantees that raw LLM provider API tokens are never written to Vidura Edge logs or persisted disk stores.
divergenceThresholdMs	Number (Integer)	450	Max millisecond delay allowed for First Token To Arrival (TTFT) before triggering instantaneous gateway arbitration.
