Natural Language compressor for LLMs (Compressed Language Model).

CLLM

Compressed Language Models via Semantic Token Encoding

---

Enterprise-grade compression for transcripts, structured data, and system prompts - achieving 60-95% token reduction.

---

🚀 Overview

CLLM is a patent-pending compression technology that dramatically reduces LLM token consumption through semantic encoding. Unlike simple abbreviation or character-level compression, CLLM preserves the meaning of your content using structured token vocabularies.

Three Core Compression Targets

1. Transcripts (Contact Centers)

• Customer service conversations
• Support call logs
• Agent-customer interactions
• 95.9% redundancy reduction (Shannon Entropy validated)

2. Structured Data (Enterprise)

• NBA (Next Best Action) catalogs
• Product configurations
• Business rule sets
• Metadata and taxonomies

3. System Prompts (Enterprise)

• Agent instructions
• Role definitions
• Operational guidelines
• Task specifications

Benefits

• 60-95% token reduction across all three targets
• Equal or better LLM responses with compressed inputs
• Up to 73% faster processing with reduced latency
• Massive cost savings for high-volume applications
• No model training required - works with existing LLMs

The Problem

In high-volume LLM environments, verbose content creates significant challenges:

• Thousands of API calls per user per day
• Rapidly escalating token costs at scale
• Infrastructure bottlenecks under heavy load
• Deployment blocked by scalability concerns
• Conversation data consuming excessive context windows

The Solution

Transcript Compression:

Customer: Hi, I need help with my account balance.
Agent: I'd be happy to help. Can I have your account number?
Customer: It's 12345678.
Agent: Your current balance is $1,450.32.

↓

[CTX:CUSTOMER_SERVICE][TOPIC:ACCOUNT_BALANCE][DATA:ACC=12345678,BAL=1450.32]

System Prompt Compression:

You are a customer service quality analyst. Analyze transcripts for compliance 
violations and sentiment issues in agent responses.

↓

[REQ:ANALYZE][TARGET:TRANSCRIPT:DOMAIN=SERVICE][EXTRACT:COMPLIANCE,SENTIMENT:SOURCE=AGENT]

Result: 85-92% token reduction, identical semantic meaning, faster processing.

🏗️ Architecture

Semantic Token Categories

Token	Purpose	Example
REQ	Actions/operations	[REQ:ANALYZE], [REQ:EXTRACT]
TARGET	Objects/data sources	[TARGET:TRANSCRIPT], [TARGET:DOCUMENT]
EXTRACT	Fields to extract	[EXTRACT:SENTIMENT,INTENT]
CTX	Contextual information	[CTX:CUSTOMER_SERVICE]
OUT	Output formats	[OUT:JSON], [OUT:TABLE]
REF	References/IDs	[REF:CASE=12345]

Compression Strategy

1. Intent Detection: Identifies the primary action (analyze, extract, summarize)
2. Target Extraction: Determines the data source and domain
3. Pattern Recognition: Maps verbose phrases to semantic tokens
4. Redundancy Removal: Eliminates 95.9% redundant information (Shannon Entropy validated)
5. Structure Preservation: Maintains relationships between concepts

🎓 Use Cases

1. Transcript Compression (Contact Centers)

Compress customer service conversations for analysis and AI processing:

from clm_core import CLMEncoder, CLMConfig

# Billing Issue - Mocking CX Transcript
transcript = "Customer: Hi Raj, I noticed an extra charge on my card for my plan this month. It looks like I was billed twice for the same subscription.\nAgent: I'm sorry to hear that, let’s take a look together. Can I have your account email or billing ID to verify your record?\nCustomer: Sure, it’s [e-mail].\nAgent: Thanks, Melissa. Give me just a moment... alright, I can see two transactions on your file — one processed on the 2nd and another on the 3rd. It seems the system retried payment even after the first one succeeded.\nCustomer: Oh wow, that explains it. So I’m not crazy then.\nAgent: Not at all. It’s a known issue we had earlier this week with duplicate processing. The good news is, you’re eligible for a full refund on the second charge.\nCustomer: Great. How long will it take to show up?\nAgent: Once I file the refund, it usually reflects within 3–5 business days depending on your bank. I’ll also send you a confirmation email with the reference number.\nCustomer: That works. Thank you for sorting it out so quickly.\nAgent: My pleasure. I’ve just submitted the refund request now — your reference number is RFD-908712. You should see that update later today.\nCustomer: Perfect. I appreciate your help, Raj.\nAgent: Anytime! Is there anything else I can check for you today?\nCustomer: No, that’s all. Thanks again!\nAgent: Thank you for calling us, Melissa. Have a great day ahead!"
cfg = CLMConfig(lang="en")
encoder = CLMEncoder(cfg=cfg)
compressed = encoder.encode(input_=transcript, metadata={'call_id': 'CX-0001', 'agent': 'Raj', 'duration': '9m', 'channel': 'voice', 'issue_type': 'Billing Dispute'})

↓

[CALL:SUPPORT:AGENT=Raj:DURATION=7m:CHANNEL=voice] 
[CUSTOMER] [CONTACT:EMAIL=[e-mail]] 
[ISSUE:BILLING_DISPUTE:SEVERITY=LOW] [ACTION:TROUBLESHOOT:RESULT=COMPLETED] 
[ACTION:REFUND:REFERENCE=RFD-908712:TIMELINE=TODAY:RESULT=COMPLETED] 
[RESOLUTION:RESOLVED:TIMELINE=TODAY] [SENTIMENT:NEUTRAL→SATISFIED→GRATEFUL]

2. Structured Data Compression (Enterprise)

Optimize NBA catalogs, product configs, and business rules:

from clm_core import CLMEncoder, CLMConfig
from clm_core.types import SDCompressionConfig

# Knowledge Base structured data
kb_catalog = [
    {
        "article_id": "KB-001",
        "title": "How to Reset Password",
        "content": "To reset your password, go to the login page and click...",
        "category": "Account",
        "tags": ["password", "security", "account"],
        "views": 1523,
        "last_updated": "2024-10-15",
    }
]
config = CLMConfig(
    ds_config=SDCompressionConfig(
        dataset_name="ARTICLE",
        auto_detect=True,
        required_fields=["article_id", "title"],
        field_importance={"tags": 0.8, "content": 0.9},
        max_field_length=100,  # Longer for articles
    )
)

compressor = CLMEncoder(cfg=config)
compressed = compressor.encode(kb_catalog)

↓

[KB_CATALOG:1]{ARTICLE_ID,TITLE,CONTENT,CATEGORY,VIEWS,LAST_UPDATED}
[KB-001,HOW_TO_RESET_PASSWORD,TO_RESET_YOUR_PASSWORD,GO_TO_THE_LOGIN_PAGE_AND_CLICK...,ACCOUNT,1523,2024-10-15]

3. System Prompt Compression (Enterprise)

Streamline agent instructions and role definitions:

compressed = encoder.encode(
    "You are a Call QA & Compliance Scoring System for customer service operations.\n\nTASK:\nAnalyze the transcript and score the agent’s compliance across required QA categories.\n\nANALYSIS CRITERIA:\n\nMandatory disclosures and verification steps\n\nPolicy adherence\n\nSoft-skill behaviors (empathy, clarity, ownership)\n\nProcess accuracy\n\nCompliance violations or risks\n\nCustomer sentiment trajectory\n\nOUTPUT FORMAT:\n\n{\n  \"summary\": \"short_summary\",\n  \"qa_scores\": {\n    \"verification\": 0.0,\n    \"policy_adherence\": 0.0,\n    \"soft_skills\": 0.0,\n    \"accuracy\": 0.0,\n    \"compliance\": 0.0\n  },\n  \"violations\": [\"list_any_detected\"],\n  \"recommendations\": [\"improvement_suggestions\"]\n}\n\n\nSCORING:\n0.00–0.49: Fail\n0.50–0.74: Needs Improvement\n0.75–0.89: Good\n0.90–1.00: Excellent"
)

↓

[REQ:ANALYZE] [TARGET:TRANSCRIPT:DOMAIN=QA] 
[EXTRACT:COMPLIANCE,DISCLOSURES,VERIFICATION,POLICY,SOFT_SKILLS,ACCURACY,SENTIMENT:TYPE=LIST,DOMAIN=LEGAL] 
[OUT_JSON:{summary,qa_scores:{verification,policy_adherence,soft_skills,accuracy,compliance},violations,recommendations}:ENUMS={"ranges": [{"min": 0.0, "max": 0.49, "label": "FAIL"}, {"min": 0.5, "max": 0.74, "label": "NEEDS_IMPROVEMENT"}, {"min": 0.75, "max": 0.89, "label": "GOOD"}, {"min": 0.9, "max": 1.0, "label": "EXCELLENT"}]}]
