Logos Router is a distributed semantic reasoning gateway that eliminates AI reasoning "drift" by fragmenting inference across local nodes with zero-drift consensus guarantees. Instead of funneling all reasoning through a single model, it distributes subproblems across a mesh of reasoning units that coordinate through a Strict Write Discipline (SWD) protocol. Every reasoning step is verified by multiple nodes before being committed, creating an immutable DAG of cognition with causal audit trails.
from logos import Router
# Initialize router with configuration
router = Router(config="config/basic_mesh.yaml")
# Single query with adaptive reasoning
response = router.query(
prompt="Explain the halting problem and its implications for AI safety",
depth="adaptive", # Can be "adaptive", 1-7, or "minimal"
language="en"
)

print(f"Nodes consulted: {response.nodes_involved}")
print(f"Consensus score: {response.consensus_score}")
print(f"Verification steps: {len(response.audit_trail)}")
Multi-Step Workflow
from logos import Router, Workflow
router = Router(config="config/advanced_mesh.yaml")
# Create a workflow for complex multi-step reasoning
workflow = router.create_workflow(
name="research_paper_analysis",
consensus=True# Enable strict consensus at each step
)
# Define workflow steps
workflow.add_step(
"extract_claims",
prompt="Extract all factual claims from this document",
input_file="papers/ai_safety_paper.pdf",
depth=5
)
workflow.add_step(
"verify_claims",
prompt="Verify each claim against known literature",
depends_on="extract_claims",
depth=7,
require_consensus=True
)
workflow.add_step(
"generate_summary",
prompt="Synthesize findings into an academic summary",
depends_on="verify_claims",
depth=6,
style="academic"
)
# Execute workflow (blocks until complete)
result = workflow.execute()
print(f"Workflow completed in {result.duration_seconds}s")
print(f"Total reasoning steps: {result.total_steps}")
print(f"Consensus failures: {result.consensus_failures}")
print(result.final_output)
Streaming Reasoning Steps
from logos import Router
router = Router(config="config/basic_mesh.yaml")
# Stream reasoning steps in real-timefor step in router.query_stream(
prompt="Design a distributed consensus algorithm for Byzantine fault tolerance",
depth="adaptive"
):
print(f"[Node {step.node_id}] Depth {step.current_depth}: {step.text}")
print(f" Confidence: {step.confidence:.2%}")
if step.requires_escalation:
print(f" ⚠️ Escalating to higher reasoning depth")
if step.consensus_reached:
print(f" ✓ Consensus reached ({step.consensus_score:.2%})")
Multilingual Reasoning
from logos import Router
router = Router(config="config/advanced_mesh.yaml")
# Query in Chinese, get response in Chinese
response = router.query(
prompt="解释量子纠缠如何影响信息理论",
language="zh",
depth=6
)
print(response.text) # Response in Chinese# Query in Spanish, request response in English
response = router.query(
prompt="¿Cómo funcionan las redes neuronales convolucionales?",
input_language="es",
output_language="en",
depth=5
)
print(response.text) # Response in English
Strict Write Discipline (SWD)
Understanding SWD Protocol
The Strict Write Discipline protocol ensures zero-drift reasoning:
Proposal: Node generates candidate reasoning step
Broadcast: Candidate sent to peer nodes for verification
Verification: Peers check logical consistency and factual accuracy
Consensus: Step committed if confidence exceeds threshold
from logos import Router
router = Router(config="config/advanced_mesh.yaml")
response = router.query(
prompt="Prove that the set of real numbers is uncountable",
depth="adaptive"
)
# Examine complete reasoning trailfor i, step inenumerate(response.audit_trail):
print(f"\n=== Step {i+1} ===")
print(f"Node: {step.node_id}")
print(f"Proposal: {step.proposal}")
print(f"Peer verifications: {step.peer_count}")
print(f"Consensus score: {step.consensus_score:.2%}")
print(f"Committed: {step.committed}")
if step.escalated:
print(f"⚠️ Escalated to depth {step.escalation_depth}")
print(f"Arbiter: {step.arbiter_node}")

Common Patterns
Pattern: Code Review with Consensus
from logos import Router
router = Router(config="config/advanced_mesh.yaml")
defreview_code_with_consensus(code_file_path):
workflow = router.create_workflow(
name="code_review",
consensus=True
)
workflow.add_step(
"analyze_structure",
prompt=f"Analyze code structure and architecture in {code_file_path}",
depth=5
)
workflow.add_step(
"identify_issues",
prompt="Identify potential bugs, security issues, and code smells",
depends_on="analyze_structure",
depth=7,
require_consensus=True
)
workflow.add_step(
"suggest_improvements",
prompt="Suggest specific improvements with code examples",
depends_on="identify_issues",
depth=6
)
result = workflow.execute()
return result
# Use the pattern
review = review_code_with_consensus("src/main.py")
print(review.final_output)
Pattern: Multi-Language Documentation Generation
from logos import Router
router = Router(config="config/advanced_mesh.yaml")
defgenerate_multilingual_docs(source_code, target_languages):
base_response = router.query(
prompt=f"Generate comprehensive API documentation for this code:\n\n{source_code}",
language="en",
depth=6
)
docs = {"en": base_response.text}
for lang in target_languages:
translated = router.query(
prompt=f"Translate this technical documentation, preserving all code examples:\n\n{base_response.text}",
input_language="en",
output_language=lang,
depth=4
)
docs[lang] = translated.text
return docs
# Generate docs in multiple languages
docs = generate_multilingual_docs(
source_code=open("api.py").read(),
target_languages=["zh", "es", "fr", "de", "ja"]
)
for lang, content in docs.items():
withopen(f"docs/api_{lang}.md", "w") as f:
f.write(content)
Pattern: Resilient Long-Running Analysis
from logos import Router
import time
router = Router(config="config/advanced_mesh.yaml")
defanalyze_large_dataset_with_checkpoints(dataset_path):
workflow = router.create_workflow(
name="dataset_analysis",
checkpoint_interval=10# Checkpoint every 10 steps
)
# Load checkpoint if existsif workflow.has_checkpoint():
print("Resuming from checkpoint...")
workflow.load_checkpoint()
workflow.add_step(
"load_data",
prompt=f"Load and validate dataset structure from {dataset_path}",
depth=3
)

prompt="Detect patterns, anomalies, and correlations",
depends_on="statistical_analysis",
depth=7,
timeout_minutes=45
)
workflow.add_step(
"generate_report",
prompt="Generate executive summary and detailed findings",
depends_on="pattern_detection",
depth=5
)
try:
result = workflow.execute()
return result
except Exception as e:
print(f"Workflow interrupted: {e}")
workflow.save_checkpoint()
raise# Execute with automatic recovery
result = analyze_large_dataset_with_checkpoints("data/large_dataset.csv")
Pattern: Adaptive Reasoning Depth
from logos import Router
router = Router(config="config/advanced_mesh.yaml")
defadaptive_query_with_fallback(prompt, max_attempts=3):
"""Try adaptive reasoning, fall back to lower depth if consensus fails"""
depths = ["adaptive", 7, 5, 3]
for attempt, depth inenumerate(depths[:max_attempts]):
try:
response = router.query(
prompt=prompt,
depth=depth,
timeout_seconds=60
)
if response.consensus_score >= 0.90:
return response
print(f"Attempt {attempt+1}: Consensus {response.consensus_score:.2%}, trying lower depth...")
except Exception as e:
print(f"Attempt {attempt+1} failed: {e}")
continue# Final attempt with minimal depthreturn router.query(prompt=prompt, depth=1)
# Use adaptive fallback
response = adaptive_query_with_fallback(
"Explain the philosophical implications of Gödel's incompleteness theorems"
)
Troubleshooting
Issue: Low Consensus Scores
Symptoms: Queries frequently fail to reach consensus threshold
Solutions:
from logos import Router
# 1. Lower consensus threshold temporarily
router = Router(
config="config/basic_mesh.yaml",
consensus_threshold=0.85# Down from 0.95
)
# 2. Increase verification peer count
router.configure_swd(verification_peer_count=4)
# 3. Check node health
status = router.get_mesh_status()
for node in status.nodes:
print(f"{node.name}: {node.health_score:.2%}")
if node.health_score < 0.80:
print(f" ⚠️ Low health - check {node.name} logs")
# 4. Inspect specific consensus failure
response = router.query(prompt="...", depth=7)
if response.consensus_score < 0.95:
for step in response.audit_trail:
ifnot step.committed:
print(f"Failed step: {step.proposal}")
print(f"Peer disagreements: {step.disagreements}")
