Coding models that hold your whole codebase in context.
FaangCoder builds frontier long-context models for software engineering. Coder-Zero, our first model, reasons over 5M tokens in a single pass, so it changes code with the whole system in view, not a handful of files.
In our internal testing, Coder-Zero performs in the same range as Opus 4.5 on real engineering tasks. Full numbers at launch.
Context measured in millions of tokens.
Most coding tools see a few files at a time. Ours see the whole thing. No chunking, no lossy retrieval, just your codebase in context.
An entire service, its tests, and its history held in a single context. Implemented, now in private preview.
Request access →Our research model, pushing context to where a whole monorepo fits in one pass. In development.
ComingBuilt for codebases, not snippets.
Whole-repo reasoning
The agent loads your full project, dependencies and tests included, so its changes fit the architecture instead of fighting it.
Autonomous resolution
Plans, edits, runs the test suite, and iterates until it is green. You review a clean pull request, not a diff dump.
Your code stays yours
Enterprise engagements include a training opt-out, so your repositories and prompts are never used to train models. Privacy controls by default.
From issue to reviewed PR.
Connect your repo
Point FaangCoder at a repository. It indexes the whole codebase and keeps it in context, no manual file selection.
Hand it the work
Assign an issue, a ticket, or a plain-language task. The agent drafts a plan grounded in your actual code.
It builds and verifies
The agent edits across files, runs your tests, and iterates on failures until the change is correct.
You review the PR
A focused pull request lands with a summary, the diff, and passing checks. Merge when you are satisfied.
Privacy first, by policy.
We are pre-launch, so these are our standing commitments, not audit badges. We publish certifications as we earn them.
No training on your code
Enterprise engagements include a training opt-out. Your repositories and prompts never train a model.
Privacy controls
Configurable handling, retention, and deletion to match your policy.
Responsible development
We hold ourselves to a published safety and readiness policy as the models scale.
Enterprise deployment
Deployment that fits your security boundary. We walk you through the options under NDA.
Early access is opening to a small group.
If you run a large codebase and want to put Coder-Zero's context to work, request access. No logos to show yet, by design.

Tell us about your codebase and what you want Coder-Zero working on. If it is a fit, we will set up a session.
- See it run on a problem like yours
- Security and deployment review
- Pilot scoping for your team
