What Teams Optimize with Weco
Prompt engineering, vision, voice, GPU kernels, ML pipelines, logistics, and more. All fully autonomous.
Prompt & VLM Optimization
Improve accuracy in vision-language pipelines. Weco iteratively improves prompts, model calls, and post-processing logic until accuracy improves across a held-out set.

Reduce GPU inference latency without changing outputs. Weco proposes and tests kernel-level changes until performance improves under the same correctness checks.

Weco autonomously generates, branches, and tests hundreds of candidate solutions - building an evolutionary tree to find the best one. Click any node to inspect examples.
Academia and Industry Recognition
Weco's innovative approach is featured in leading research papers and industry publications
Deployable Breakthroughs on Autopilot
Ship speedups overnight
Weco proposes, tests, and iterates on code changes autonomously - wake up to optimized code.
Sweep candidates for pennies
Each candidate costs fractions of a cent. Find the non-obvious wins that manual iteration misses.
Your data never leaves your machine
Eval code runs locally where your data lives. Only metrics and diffs are sent - review the open-source CLI to verify.
Works with any language
Python, C++, Rust, JS - if it prints a metric to stdout, Weco optimizes it.
See every experiment in one tree
Each run produces a searchable tree of candidates. Compare any two nodes side-by-side.
Steer with natural language
Add constraints like "avoid unsafe memory access" or "prioritize readability" to guide the search.
It's as Simple as:
1. Point Weco to your eval
Provide a command that prints your metric value to stdout, which will be used to...
2. Run the Weco optimization
Weco proposes code edits, runs local eval, and evolves solutions based on findings.
3. See and ship breakthroughs
Watch progress locally or in the dashboard and see results before merging the winner.

The Next Generation of AIDE ML - Now in the Weco Platform
Outperforming competitors with systematic iteration and optimization focused on measurable results
OpenAI Benchmarked
Metric-first engineering that wins more medals on MLE‑Bench:
AIDE ML iterates until the metric says "better." In OpenAI's MLE‑Bench it secured 4× more medals than the next best autonomous agent across 75 Kaggle competitions.
An explicit evaluation loop beats one‑shot code generation.
Beyond Human Baselines
Consistently surpassing experts on tight time‑boxed research tasks:
In METR's 6‑hour RE‑Bench challenge, AIDE consistently outperformed seasoned researchers, surfacing "surprising" solutions humans missed.
Open‑Source & Live Now
Use the best version of AIDE ML on the Weco Platform today:
AIDE's core is open‑source - explore the repo or read the paper to dive deeper into our approach.
The Weco Platform is live. Install the CLI with pip install weco, run it against your evaluation script, and watch every experiment stream to the Dashboard in real time. Want a voice in new features? Join the newsletter.
