KeelCore: one compact base, small adapters, built to run on your device

**KeelCore is one compact base model plus many small LoRA adapters.** We pretrain the base once. A new capability then arrives as a small adapter, not a new model, so you download the base once and add only the adapters you need.

## Models | Model | Status | Details | |---|---|---| | **KeelCore‑750M** | Base model | 752M parameters, encoder–decoder, 2,048-token context. English, code and command line. | Benchmarks, including where we trail models trained on larger budgets, are on the model card. ## Adapters An adapter is a small, separate download that works only with the base it was trained on. You install the base once, then pick the adapters you need. | Adapter | Status | |---|---| | Text-rewriting adapters | In training | | Other domains, for example legal and marketing writing | Planned (no dates) | We plan one repository per adapter, named after the base and the task (`KeelCore-750M-`), possibly at more than one LoRA rank. This page will list each one when it is released. ## Why this approach * **One base.** A single pretrained encoder–decoder with a tokenizer built for English prose, source code and command-line text. * **Small adapters.** A rank-16 LoRA adapter trains about 18.3M parameters, 2.4% of the base, while the base weights stay frozen. * **Runs on your device.** A weight-only int8 ONNX export (0.76 GB) runs in a web browser through ONNX Runtime Web. Because that runtime could not load LoRA adapters, we contributed the support ourselves: a `LoraAdapter` API and an `activeLoraAdapters` run option, merged in October 2026 (microsoft/onnxruntime#32886). ## Built with KeelCore **EchoMeBetter** is the first product built on KeelCore: a browser extension that runs the base and its text-rewriting adapters on your device. It is one application, not the purpose of KeelCore, which is a general base for adapters. ## License Models are released under the **KeelCore License, Version 1.0**: personal use through the official EchoMeBetter extension and noncommercial research, which requires citing the project. Commercial use, use by an organization and any use outside the extension need a separate written agreement. Adapters follow the same terms unless their repository says otherwise. ## Contact **Saravanan A R** · LinkedIn · GitHub Commercial licensing and partnerships: sararavi.ar@gmail.com
