Trust every AI response. Verify before you deliver.
VeriLLM validates LLM outputs in real-time, catching hallucinations and factual errors before they reach your users. Simple SDK integration. Works with any LLM provider.

LLMs are powerful — but they lie
Every AI application in production faces the same critical risk: hallucinated outputs that erode trust and create liability.

Hallucinations
LLMs confidently generate false information. Your users can't tell the difference — but your reputation pays the price.
Legal Liability
AI-generated misinformation can lead to lawsuits, regulatory fines, and compliance violations. "The AI said it" is not a defense.
Compliance Risk
Healthcare, finance, and legal sectors demand factual accuracy. One wrong AI response can trigger regulatory action.
The Solution
One line of code. Zero hallucinations delivered.
VeriLLM validates your LLM responses against source documents. Your app stays in control. Every response is validated in real-time before reaching your users.
from openai import OpenAI
import verillm
client = OpenAI(api_key="your-key")
veri = verillm.VeriLLM(api_key="veri_...")
# Your normal LLM call — unchanged
response = client.chat.completions.create(
model="gpt-4",
messages=[{"role": "user", "content": "..."}]
)
# Validate before delivering to user
result = veri.validate(
response=response.choices[0].message.content,
reference=your_source_documents
)
if result.flagged:
handle_hallucination(result.flagged_claims)Simple SDK Integration
Add 3 lines of code to your existing pipeline. Works with OpenAI, Anthropic, Mistral, or any LLM. Your LLM calls stay direct — VeriLLM validates alongside.
Real-time Validation
Every claim is extracted and verified against YOUR source documents using NLI models — before the response reaches your user.
Actionable Verdicts
Get a trust score, flagged claims with explanations, and suggested corrections. Block, warn, or log — you decide the policy.
< 200ms Overhead
Optimized NLI models and intelligent caching keep latency minimal. Your users won't notice — but they'll trust you more.
How It Works
Four steps to trustworthy AI
Our validation pipeline runs in milliseconds, ensuring every response is trustworthy before it reaches your users.
Claim Extraction
VeriLLM parses the LLM response and extracts individual factual claims that can be independently verified.
NLI Verification
Each claim is cross-referenced against your source documents that you provide using state-of-the-art Natural Language Inference models.
Confidence Scoring
Every claim receives a confidence score based on evidence strength. Low scores flag potentially hallucinated content.
Decision
Based on your policy, responses Pass, Flag for review, or Block entirely. Users see only what you've approved.
Latency: <200ms additional overhead
