## 🔷 Who We Are

**Rhombus** is an independent AI research & engineering studio focused on **small, efficient, and reasoning-strong models**. We prototype new architectures, build high-quality datasets, and ship production tools that work **offline**, on **low compute**, and in **real-world constraints**.

Our guiding principles:

* **Geometry over noise**: clear structure, measurable outcomes, minimal bloat.
* **Small-first**: design models that outperform their size class.
* **Reasoning-centric**: prioritise logic, reliability, and controllability.
* **Accessible**: reproducible, transparent, documented for students & startups.

---

## 🧭 Mission

1. **Re-think model architecture** beyond classic Transformers for efficiency and robustness.
2. **Compress intelligence** — make 50M–2B parameter models reason like much larger ones.
3. **Democratise training** with tooling that runs on consumer GPUs and CPU-only environments.
4. **Ship pragmatic AI** — tools that solve real problems in coding, data, education, and research.

---

## 📦 Key Projects (Active/Planned)

### 🧪 Architectures & Models

* **Brahma** — a *post-transformer* research line targeting minimal compute with strong reasoning and robustness.
  *Goal:* beat GPT-2 class baselines with a fraction of compute.
* **Water v0.x** — early Brahma-based series (5M → 100M) proving the concept with rigorous evals.
* **Karta 135M** — fine-tuned SmolLM-based series for compact instruction following.
* **Kishor** — a multilingual reasoning LLM family (Hindi/Hinglish/English) with strong coding skills.
  *v3 target:* \~2.2B params, balanced for edge + server.

### 🖼️ Generative & Multimodal

* **Klaa** — text‑to‑image model (Mk 2.5+) with robust prompt alignment and style control.
* **Rhombus TTS** *(R\&D)* — lightweight text‑to‑speech optimized for clarity on consumer GPUs.

### 🧰 Tooling

* **Rhombus CorpusForge** (aka *DataCrafter*) — offline dataset factory: dedup, filtering, chunking, quality lift, export for training.
* **Project Fruit** — dataset classification + high‑quality custom instruction sets for fine‑tuning compact models.

---

## 🗺️ Roadmap Snapshot

* **2025**: Brahma research notes, Water v0.2 (100M), CorpusForge alpha, Karta 135M releases.
* **2026**: Kishor v3 training; robust multilingual/coding evals; Klaa Mk 3.
* **2027**: Brahma v1 reference; inference SDK; offline QA/coding assistant.
* **2028–2030**: Scaled Brahma family; unified multimodal small models; education-first deployments.

> Detailed per-quarter milestones live in the organization Projects board.

```

### Tagging & Naming

* Repos: `area-name` (e.g., `architecture-brahma`, `tooling-corpusforge`).
* Branches: `main` (stable), `dev` (active), `exp/<topic>` (short‑lived).
* Releases: semantic tags `vMAJOR.MINOR.PATCH` + training/build metadata.

## 📊 Evaluation & Benchmarks

We care about **reasoning** over raw next-token loss. Our standard evals:

* **Language**: MMLU, ARC, HellaSwag, TruthfulQA, WinoGrande, BIG‑bench (selected), XNLI subset (Hindi/English)
* **Coding**: HumanEval+, MBPP, Codeforces-style synthetic stacks
* **Safety**: jailbreak suites, refusal correctness, harmful content filters
* **Image** (Klaa): FID-like proxies, CLIP‑score, prompt adherence, style robustness

> *We publish exact prompts, seeds, decoders, and compute for reproducibility.*

---

## 🔐 Safety, Security & Governance

* **Alignment**: instruction tuning with preference data; safety rail prompts; content filters on output.
* **Security**: supply-chain checksums, signed releases, deterministic builds when possible.
* **Privacy**: strict dataset licensing review; PII scrubbing; opt‑out channels.
* **Ethics**: transparent data sources; clear intended use; red‑line misuse policy.

---

## 📄 Licenses

* **Code**: Apache-2.0 (preferred) or MIT when noted.
* **Models**: Apache-2.0 / OpenRAIL / custom Responsible AI license depending on risk profile.
* **Datasets**: Original content under CC‑BY‑4.0 or CC‑BY‑SA‑4.0; third‑party per-source.

> Each repo contains a clear `LICENSE` and `NOTICE` with third‑party attributions.

---

## 🧪 Reproducibility Policy

For every release we strive to provide:

* **Training recipe**: data mix, token count, curriculum, batch schedulers.
* **Compute**: GPU/TPU type, hours, energy notes.
* **Exact checkpoints**: with SHA256, quantized variants, and safetensors.
* **Configs**: tokenizer, architecture params, decoder settings.

## 🧱 Contribution Guide (Quick Start)

### 1) Discuss

Open an **issue** in the relevant repo with a clear proposal. Use the `proposal` template.

### 2) Develop

* Fork the repo, create `exp/<topic>` branch
* Follow code style (ruff/black for Py, ortho tests, mypy optional)
* Add/Update docs and unit tests

### 3) Submit

Open a PR to `dev` with:

* motivation, design notes
* benchmarks (even small‑scale)
* safety considerations

### 4) Review & Merge

* 2 approvals minimum for core repos
* CI must pass (lint, tests, basic eval sanity)

> See `CONTRIBUTING.md` in each repo for details.
