VoxCPM

open sourceexplicit relation

VoxCPM is an open-source text-to-speech system from OpenBMB generating continuous speech across 30 languages without traditional tokenization. Its 2B parameter end-to-end diffusion architecture produces 48kHz studio-quality audio with natural prosody and emotion. Key capabilities include voice design from text descriptions, few-shot voice cloning, and multilingual synthesis without language-specific modules. The Apache 2.0 project has 8,700 GitHub stars.

Free and open source under Apache 2.0 license

Coqui TTS

open sourceexplicit relation

Coqui TTS is an open-source deep learning toolkit for text-to-speech synthesis, originally built by former Mozilla TTS engineers. It supports multi-speaker and multilingual synthesis, voice cloning from just six seconds of audio, and ships pre-trained models for 20+ languages. After Coqui shut down in 2023, the Idiap Research Institute forked and actively maintains it. With 45K+ GitHub stars, it remains the most popular open-source TTS framework in Python.

RayRay is an open-source distributed computing framework built for scaling AI and Python applications from a laptop to thousands of GPUs. It provides libraries for distributed training, hyperparameter tuning, model serving, reinforcement learning, and data processing under a single unified API. Ray's public site highlights OpenAI and other enterprise users. Maintained by Anyscale with Apache-2.0 open-source licensing.LLaMA-FactoryLLaMA-Factory is an open-source toolkit providing a unified interface for fine-tuning over 100 LLMs and vision-language models. It supports SFT, RLHF with PPO and DPO, LoRA and QLoRA for memory-efficient training, and continuous pre-training. The LLaMA Board web UI enables no-code configuration, while CLI and YAML workflows serve advanced users. Integrates with Hugging Face, ModelScope, vLLM, and SGLang for model deployment.UnslothUnsloth is an open-source framework for fine-tuning large language models up to 2x faster while using 70% less VRAM. Built with custom Triton kernels, it supports 500+ model architectures including Llama 4, Qwen 3, and DeepSeek on consumer NVIDIA GPUs. Unsloth Studio adds a no-code web UI for dataset creation, training observability, model comparison, and GGUF export for Ollama and vLLM deployment.VibeVoiceVibeVoice is Microsoft's open-source voice AI family with both TTS and speech recognition models. The TTS model generates up to 90 minutes of expressive multi-speaker audio with 4 distinct voices. VibeVoice-ASR transcribes 60-minute recordings in a single pass with speaker identification and timestamps. Built on continuous speech tokenizers at 7.5 Hz and next-token diffusion, it compresses audio 80x more efficiently than Encodec while preserving fidelity.MetabaseMetabase is an open-source business intelligence and embedded analytics platform for teams that want self-service dashboards, SQL workflows, and customer-facing analytics without adopting a heavy BI suite. It supports visual querying, saved questions, alerts, database connectors, cloud or self-hosted deployment, and embedding paths that now require careful plan, permission, and license review.Weights & BiasesWeights & Biases is an AI developer platform for experiment tracking, artifact and model lineage, model monitoring, and Weave-based LLM evaluation. It helps teams log runs, compare metrics, manage datasets and model artifacts, and collaborate through dashboards, reports, alerts, SSO/RBAC controls, and hosted or self-managed deployment options.CleanlabCleanlab is a data-centric AI library that automatically detects and fixes label errors, outliers, and data quality issues in machine learning datasets. It works with any ML model and any data type including text, images, tabular, and audio by analyzing model predictions to identify mislabeled examples, near-duplicates, and ambiguous data points. Cleanlab helps teams improve model accuracy by cleaning training data rather than tuning model architecture.AirweaveAirweave is an open-source context retrieval platform that connects AI agents and RAG systems to 50+ apps and databases through a unified search interface. It continuously syncs data from sources like Notion, Slack, GitHub, and databases, making it searchable through LLM-friendly APIs. Airweave includes Python and TypeScript SDKs, MCP support, and a CLI for managing data connections.ArgillaArgilla is an open-source platform for curating and annotating data for LLM fine-tuning and RLHF workflows. It provides collaborative annotation interfaces for text classification, ranking, and preference labeling with integrated quality metrics. Part of the Hugging Face ecosystem, Argilla supports direct dataset publishing to the Hub and integrates with major training frameworks for seamless model improvement pipelines.
