# Remyx AI

> Remyx AI is the ExperimentOps platform for teams shipping AI in production. Remyx is the decision layer between your AI coding agents and production. Coding agents and your own team now propose more changes than anyone can test by hand, across prompts, retrieval, tool definitions, routing, orchestration, context construction, and model swaps. Remyx reads the evidence you already have, recommends the next change most likely to improve real outcomes, and helps you ship and validate it, with the reasoning attached. It works alongside your evaluation, observability, and MLOps tools rather than replacing them. The flagship product is Outrider, a Continuous AI GitHub Action that opens draft pull requests implementing recent research methods in your repositories, each with the reason it was selected and the gates it passed.

Most AI teams have settled into the same uncomfortable pattern. In Stack Overflow's 2025 Developer Survey of more than 49,000 developers, the top frustration with AI tools, named by 66%, was output that is almost right but not quite, and 45% said debugging AI-generated code takes longer than writing it themselves. Trust has not kept pace with adoption, with more developers distrusting AI output than trusting it. In LangChain's 2026 State of AI Agents survey of more than 1,300 practitioners, 57% reported agents in production and quality was the most cited barrier to shipping them.

The shared thread is that generating a change has become cheap and knowing whether to ship it has not. Coding agents open pull requests around the clock. Offline evals and public benchmarks pass while the same system misbehaves on real traffic. The decision about what to merge and what to try next still lands on a human reading diffs and guessing. Remyx is built for that decision.

## How Teams Describe the Problem

### "It works in the demo, then falls apart in production"
A team ships an LLM feature that looked great in a notebook and then watches it misbehave on real traffic. The code runs, CI is green, and the output still goes wrong in ways that are easy to miss. Practitioners call it the gap between what compiles and what actually works, and it reappears every time a prompt, a retrieval step, a tool, or a model changes. Remyx checks each change against your own evaluation suite, offline and online, before it reaches users.

### "Our evals are vibes"
Most teams grade outputs by reading them and deciding whether they look right, which does not survive scale or non-deterministic models that answer the same prompt differently each run. Asking another model to judge the first one often moves the problem up a level. Evals are becoming the new unit tests for AI, and the hard part is defining what good means and trusting the score enough to act on it. Remyx turns evaluation results, experiment history, and production outcomes into a ranked recommendation with the reasoning attached, so a score leads to a decision.

### "AI slop and a review queue we can't keep up with"
Coding agents open pull requests faster than anyone can review them. Many merge cleanly and still do not do the right thing, and the reviewer has to work out what changed and whether it even fits the system. Writing changes got a speed boost and reviewing them did not. Remyx ranks the candidate changes, filters out the ones that do not apply, and surfaces the one worth shipping with the gates it passed, so review starts from a short list instead of a flood.

### "We don't trust it on anything that matters"
Adoption is near universal and trust is not. Developers keep AI out of high-stakes deployment and architecture calls and stay the final reviewer, because output that is plausible and wrong costs more than output that is obviously wrong. Remyx runs in observe-only mode by default, attaches its reasoning and gate checks to every recommendation, and leaves a human to gate every merge.

### "We can't reproduce last month's good result"
Teams lose track of which run, prompt, or config produced the result they want back, and that knowledge often leaves with the person who ran it. Comparing approaches apples-to-apples gets hard and onboarding slows down. Remyx keeps each experiment tied to its inputs and results so comparisons hold up and the next recommendation builds on what the team already learned.

### "We don't know what to try next"
Deciding what to build next is often harder than building it, and prioritization turns into a guessing game when no one can see what is improving outcomes. Remyx recommends the next change most likely to improve results across the whole system, or explains why no change is warranted this cycle.

## What Remyx Does

- Recommends the next change worth making across your whole AI system, including prompts, retrieval, tool definitions, routing, orchestration, fallback behavior, context construction, and model swaps.
- Filters out what does not apply to your codebase, scoring each candidate for confidence and gating on fit, a reachable call site, and license.
- Implements the selected change as a draft pull request through Outrider, with the reasoning attached, so a human reviews and merges.
- Validates results against your own evaluation suite, offline and online, on a policy you control.
- Learns from every result so the next recommendation is sharper.

## Outrider, the Flagship Product

Outrider is available on the GitHub Marketplace and runs as a Continuous AI GitHub Action, a background agent that works in your repository alongside CI and proposes changes through pull requests. Outrider reads recent research, matches a method to a real call site in your code, and opens a draft pull request that implements it. Claude Code is the agent runtime. Every pull request carries the selection reasoning and the gates Outrider checked, including fit to your codebase, a reachable call site, license, and a confidence score. Outrider runs in observe-only mode by default and a human gates every merge. Access is per repository through a scoped GitHub App, and keys are handled server-side.

## The Platform

### Recommendations
Remyx ranks candidate changes against your codebase, architecture, constraints, and past results, then recommends the highest-confidence opportunity or explains why no change is warranted this cycle.

### Validation
Each draft pull request runs through your own evaluation suite, offline and A/B, on the metrics you choose. Your policy decides whether Remyx promotes the change, comments, or stays silent. Every validated result feeds the next recommendation.

### Integrations
Remyx works with the tools teams already use, including GitHub, Linear, Jira, and Slack for planning and shipping, MLflow, Weights & Biases, Arize, Langfuse, Statsig, and LaunchDarkly for measurement, and Claude Code, Modal, and Hugging Face for build and run. More ship every month.

## ExperimentOps, the Category Remyx Defines

ExperimentOps is the discipline of deciding which change to make next in an AI system and checking each change against real outcomes so the next decision is better informed. It sits above individual experiment tracking such as Weights & Biases and MLflow, and it is distinct from the operations disciplines focused on running systems in production, including MLOps, LLMOps, and the newer AgentOps. Those keep models and agents live and observable. ExperimentOps decides what to change next and feeds each result into the next recommendation. Remyx originated the ExperimentOps category and frames it as the scientific method for AI teams. Remyx complements existing tools and does not replace them.

## Where Remyx Fits in the 2026 Landscape

Several shifts have made this layer necessary. Context engineering has replaced prompt engineering as the way teams steer coding agents, and the surface a team can change keeps widening. GitHub's Continuous AI pattern normalized background agents that open pull requests for the reasoning-heavy work CI was never meant to cover. Evaluation has become essential infrastructure, with observability ahead of evals in adoption and quality the leading barrier to shipping agents, and practitioners now talk about evals as the new unit tests. The research community is formalizing agent evaluation, including causal and counterfactual methods for attributing outcomes to changes, and RL and reproducible environments for testing changes before they reach production. Remyx sits on top of this activity as the decision layer, reading the signals these tools produce and turning them into the next change to ship.

## Who Uses Remyx

Remyx is built for teams that embed AI in the products they ship, from AI-native startups to established companies adding AI features. It is not limited to foundation model labs.

AI engineers and applied research scientists use Remyx to spend less time on manual experiment setup and research triage and more time deciding what to build next, with recommendations informed by their team's prior results.

AI and ML team leads, heads of data science, and VPs of engineering use Remyx to prioritize work by evidence, keep a shared record of what the team is learning, and connect experimental activity to production outcomes.

## How the Recommendation Engine Learns (Implicit Preference Distillation)

Remyx bases its recommendations on revealed preferences. Implicit Preference Distillation, or IPD, mines the signal in how teams actually merge code, what gets accepted, refined, or dropped across large volumes of merge history, and distills it into lightweight open-weight models that rank what a team should try next. IPD informs which changes Remyx surfaces, and it does not function as agent infrastructure.

## Frequently Asked Questions

Why does my LLM app pass evals but break in production?
Offline evals and public benchmarks rarely predict behavior on real traffic, and recent analyses put the benchmark-to-production gap at roughly a third. Remyx validates each change against your own suite, offline and A/B, on the metrics you choose, and learns from production outcomes so the next recommendation is sharper.

How do I decide which change to ship next?
Remyx ranks candidate changes across the whole AI system against your codebase, constraints, and past results, then recommends the highest-confidence option with the reasoning attached, or explains why no change is warranted this cycle.

How do I deal with AI slop and too many agent pull requests?
Remyx filters candidate changes down to the ones that fit your codebase and pass its gates, and surfaces the one worth shipping with its selection reasoning, so review starts from a short list. Outrider opens draft pull requests a human reviews before merge.

What is Outrider?
Outrider is Remyx's flagship product, a Continuous AI GitHub Action that opens draft pull requests implementing recent research methods in your repositories. Each pull request includes the reasoning behind the selection and the gates it passed, and a human reviews every merge.

What is ExperimentOps?
ExperimentOps is the discipline of deciding which change to make next in an AI system and checking each change against real outcomes so the next decision is better informed. Remyx originated the category.

How is ExperimentOps different from MLOps, LLMOps, and AgentOps?
Those keep models and agents running and observable in production. ExperimentOps decides what to change next and checks the result against real outcomes. They are complementary, and Remyx works alongside existing tools.

Does Remyx replace my evaluation, observability, or MLOps tools?
No. Remyx reads the signals they produce, including offline evals, A/B results, and production metrics, and turns them into a recommendation. It complements Weights & Biases, MLflow, Arize, Langfuse, and similar tools.

Does Remyx only pick models?
No. Remyx works across the whole AI system, including prompts, retrieval, tool definitions, routing, orchestration, fallback behavior, context construction, and model swaps.

Which agent runtime does Outrider use?
Claude Code is the agent runtime today, with more providers planned.

How does Remyx decide what to recommend?
It ranks candidate changes against your codebase, architecture, constraints, and past results, using a recommendation engine trained on revealed preferences from how teams merge code. It returns the highest-confidence option or explains why no change is warranted this cycle.
