Memory Routing Agent

A specialized 8B model that outperforms its 104B teacher on marketing conversation classification.

The Experiment

This project demonstrates prompt distillation: training a small, specialized model to outperform the large model that generated its training data.

The Challenge

Marketing AI assistants need to remember the right information from conversations. Not everything is worth storing - you need to distinguish between:

Valuable: "Our brand voice is professional but approachable" → Store in long-term memory
Transactional: "What time is the meeting tomorrow?" → Don't store

This is a 13-category classification problem with nuanced distinctions between company-level and user-level information, different persistence horizons, and the critical ability to say "none" for irrelevant content.

The Approach

Generate synthetic data using Cohere Command-R-Plus (104B) as the teacher
Fine-tune Llama-3.1-8B with LoRA using Tinker's training platform
Apply reinforcement learning with a custom reward function
Benchmark against the teacher on challenging, held-out scenarios

The Result

Model	Parameters	Avg F1	Exact Match
Ours	8B	0.68	60%
Cohere Command-R-Plus	104B	0.61	26%

Our 8B model achieves 11.1% higher F1 and 2.3x better exact match accuracy than the 104B teacher, while being 13x smaller.

The student surpassed the teacher through:

Focused training: The model only learns this one task, not general capabilities
RL refinement: The reward function optimizes for exact category matching, not just plausible outputs
Clean data: Synthetic data with consistent labeling, no noise from human annotation disagreements

Training Visualizations

Phase 1: Supervised Fine-Tuning

100 training steps reduced loss from 5.47 to 0.26 (95% reduction). The model learned the basic classification task in the first epoch.

Phase 2: Reinforcement Learning

30 RL iterations improved mean reward from 0.73 to 0.93. The reward function combines F1 score, temporal alignment, scope correctness, and storage efficiency.

Model Comparison

Our model excels at exact matching (60% vs 26%) because RL optimizes for getting all categories right, not just some.

Performance by Difficulty

The 8B model dominates on easy cases (+79% F1) and matches on medium cases. The 104B model still wins on hard multi-label scenarios.

Key Results

Metric	Our Model (8B)	Cohere (104B)
Avg F1	0.68	0.61
Exact Match	60%	26%
Any Match	72%	82%
Model Size	8B	104B
Improvement	+11.1% F1	baseline

Reward Components (Final RL Iteration)

Component	Score	Description
R_F1	0.90	F1 score vs gold labels
R_temp	0.95	Temporal alignment
R_parity	1.00	Company/user scope
R_eff	1.00	Storage efficiency

What It Does

The Memory Routing Agent classifies marketing conversations into 13 memory categories:

Company Categories (Long-term business context)

Category	Description	Persistence
`company.brand_core`	Voice, values, positioning	Long (>1y)
`company.strategic_signatures`	Decision frameworks	Long (>1y)
`company.knowledge_artifacts`	Docs, style guides	Long (>1y)
`company.business_priorities`	Quarterly goals	Short (<3m)
`company.tools_config`	Integrations, APIs	Medium (~6m)
`company.performance_context`	Campaign metrics	Rolling (~6m)

User Categories (Personal preferences)

Category	Description	Persistence
`user.communication_style`	Tone, format preferences	Long (>1y)
`user.strategic_approach`	Personal priorities	Long (>1y)
`user.role_context`	Title, scope	Medium (~1y)
`user.workflow_patterns`	Review cadence	Medium (~1y)
`user.session_history`	Immediate context	Short (<2w)
`user.interaction_preferences`	Coaching style	Evolving

Special

Category	Description
`none`	Transactional or irrelevant content
