Olaverse Documentation

Welcome to the official developer documentation for the Olaverse SDK.

Olaverse is an open-source multilingual AI infrastructure toolkit for building NLP, speech, retrieval, and language systems for underrepresented languages.

30-Second Quick Start

pip install olaverse

from olaverse.nlp import Diacritizer

d = Diacritizer(model="auto")       # detects the language, routes to the right model
d.restore("Ojo lo si oja lana")     # → 'Òjó lọ sí ọjà lana'

# 10 languages via the multilingual model (pip install olaverse[deeplearning]):
d = Diacritizer(model="diacnet-1.0", lang="yo")
d.restore("se eranko naa si gbo o?")   # → 'ṣé ẹranko náà sì gbọ́ ọ?'

New in v0.2.0 — title and question generation (pip install olaverse[deeplearning]):

from olaverse import MISTTitleGenerator, MISTQuestionGenerator

MISTTitleGenerator().generate("My laptop keeps freezing when I open too many tabs, why?")
# → 'Laptop Freezing Impact'

MISTQuestionGenerator().generate(passage, n=3, language="eng")
# → ['What causes ocean tides?', 'Does the sun affect tides?', ...]

Key Capabilities

• 🗣️ Natural Language Processing: Diacritization for 10+ languages (Yoruba, Igbo, Hausa, Vietnamese, Polish, Turkish, Portuguese, Spanish, French, Italian via diacnet-1.0), Language Detection from 5 to 25 languages (LIDLite5/LIDNeural5, LIDLite25/LIDNeural25, and the Nigerian-only LIDNeural5_1), Byte-Level BPE tokenization (Nigerian languages plus Swahili/Kinyarwanda/merged families), PII masking, and TTS text normalization.
• ⚡ MIST Model Family: Unified interface for the MIST LLM family (8B, 70B, 140B, Thinking). Supports local inference via transformers and hosted inference via Featherless or any OpenAI-compatible endpoint. Correct stop tokens and generation defaults per variant are baked in. Plus two task-specific models: MISTTitleGenerator (short chat titles from a user's first message) and MISTQuestionGenerator (search-style question generation from a passage, across 25 languages).
• 🧠 Domain LLMs: LegalPeace — memory-efficient 4-bit inference for legal contract reasoning (fine-tuned Mistral-7B-v0.3).
• 🔎 Retrieval: Reranker (cross-encoder, RAG/search second stage) and Embedder (cross-lingual Hausa/Yoruba/Igbo sentence embeddings).
• 🖼️ Vision — Prism: PrismUpscaler (2x/4x/arbitrary-resolution super-resolution), PrismDenoiser (noise/blur/compression removal), and PrismSteganography (hide/recover short messages in images).
• 📊 Datasets: load_dataset / list_datasets — direct access to every public olaverse dataset on Hugging Face (reranker training pairs, multilingual QG passages, DiacBench, and more).
• 🎙️ Speech Architecture (Roadmap / Experimental): TTS pipeline architecture connecting normalization, diacritization, acoustic model, and vocoder. The NLP front-end is production-ready; acoustic synthesis is in development.
• 🌍 Global Utilities: Currency formatters, generic constants, and .wav audio I/O tools.
