MEGA Code

Evaluation-Driven Development
One loop, every run smarter than the last

Optimization is not a one-shot improvement. It's a continuous loop that runs until performance stops improving.

Each cycle compounds on the last. The system gets better at the job every time it runs the job.

Drop your codebase. Optimization starts.

Whether your agent is already in production or still mid-build, point MEGA at the repo. It picks up your evaluation method and dataset, then runs the loop — every iteration from there is automated.

Single input · zero setup

Point MEGA at the repo. The loop takes it from there.

  • Production agent. MEGA tunes against the workload you actually serve.
  • In development. Wire eval and data once; every iteration converges on the metric you defined.

How the loop runs

Every epoch starts smarter than the last. The Wisdom Graph is the memory that makes compounding possible.

Sample Training Set (Seed k)

Epoch Start

A fixed subset of the dataset is sampled for this epoch. This stable target is what every iteration has to beat.

Baseline Measurement

Performance is measured before any changes. This is iter_0. The number every future iteration is scored against.

Wisdom Curation

Iter 1

The Wisdom Graph assembles the best-fit execution structure for this task. Not a retrieval dump. A curated orchestration.

Iterative Refinement

Iter 1 → N

Execute. Validate. Refine. Repeat. Each iteration adjusts from feedback and compounds gains on the fixed subset until saturation.

Validation Data Test

Epoch Boundary

Gains are verified against unseen data. Confirms improvements generalize — not overfit to the subset. Validated gains close the epoch.

Loop Continues

When the loop restarts, the Wisdom Graph carries forward everything learned from epoch k. Gains compound across epochs, not within them.

Use Cases

Wherever your pipeline has a signal of success,
MEGA compounds it

Every production LLM pipeline has some way of knowing what “working” looks like. A correct label, a retrieved document that belonged, a passing test, a trajectory that completed. That signal is what lets an optimization loop learn. These are the patterns MEGA Code runs on most often, but not the only ones it works for.

Classification & Routing

  • Intent Classification
  • Sentiment analysis
  • Topic routing
  • Conditional routing
What MEGA learns

Which prompts and decision boundaries survived edge cases, and which collapsed. Accuracy grows across runs instead of resetting.

Structured extraction

  • NER
  • Relation extraction
  • Event extraction
  • Keyphrase extraction
What MEGA learns

Every corrected extraction — wrong span, missing entity, mis-linked relation — becomes a reusable pattern. Quality improves the more you run it.

extract

Retrieval & RAG

  • Keyword retrieval
  • Dense retrieval
  • Hybrid search
  • Multi-hop QA
What MEGA learns

Which documents matter for which query types, and which retrieval strategies fail on which edges. Precision compounds with use.

Generation

  • Summarization
  • Translation
  • Code generation
  • Open QA
What MEGA learns

Patterns in what gets corrected, rejected, or re-written. Generation tightens across runs, not just for one prompt.

NL to structured

  • NL → SQL
  • NL → Function call
  • NL → JSON
  • Schema migration
What MEGA learns

Which phrasings mapped to which structures, and which hallucinated arguments got rejected. Reliability grows per session.

Agentic tool use

  • Single-call routing
  • Multi-step tool use
  • Code execution agents
What MEGA learns

Successful trajectories become reusable strategies. The agent stops re-discovering what already worked.

Competitive Advantage

The gap isn't in prompt tuning.
It's in everything underneath.

Every serious tool can tune a prompt. The deeper the optimization reaches, into the workflow structure,

the evaluation data, the curation logic, and eventually the optimization strategy itself.

The fewer systems still operate there. MEGA Code is the only one that reaches every layer.
