Weights & Biases
API service
Hosted inference service for open-source and commercial LLMs (OpenAI, Qwen, Llama, Kimi, Phi, DeepSeek, Z.AI) without managing infrastructure.
Developer tool
Tracing, evaluation and production monitoring for LLM and agent applications, capturing each call so prompts and outputs can be scored over time.
Platform
Experiment tracking for model training runs, recording hyperparameters, metrics and artifacts so runs can be compared, swept and reproduced.
Curated central repository providing versioning, aliases, lineage tracking and governance for models and datasets across the ML lifecycle.
Managed reinforcement-learning fine-tuning service for LLMs on CoreWeave's managed GPU cluster, billed per-token for rollouts with automatic scale-to-zero.
Serverless supervised fine-tuning for LLMs on CoreWeave's managed GPU cluster, run alongside Serverless RL in a unified workflow via the Agent Reinforcement Trainer (ART) API.
Yandex
API service
Speech recognition and speech synthesis API built on the technology behind the Alice assistant, used for voice assistants, call-centre automation and service-quality monitoring.
Neural machine translation API supporting more than 100 languages, sold as a Yandex Cloud service.
Computer-vision API that recognises and extracts text, tables, handwriting, document fields and licence plates from images and PDFs in 48 languages.
Developer tool
Yandex's AI coding assistant for VS Code and JetBrains IDEs, offering completion, chat, code review and an agent mode that carries out development tasks from natural-language instructions.
Platform
Yandex Cloud platform that serves Yandex's generative models (YandexGPT, YandexART, embeddings, classifiers) over an API, with fine-tuning, a model gallery and agent/assistant tooling.
End-to-end managed ML development environment with notebooks, distributed training jobs and one-click model deployment on elastically scaled CPU/GPU resources.
No counterpart
Yandex sells these in a stack layer with no product recorded for Weights & Biases yet — nothing on the other side to compare them against.
Application
Yandex's consumer AI assistant and chat product, which answers questions with web search, analyses uploaded files, and generates text and images from Yandex's own generative models.
Speech-analytics service that transcribes and analyses voice and text customer conversations to surface topics, sentiment and service-quality metrics.
