SDK Overview
Learn the Python interfaces for workflows, graders, contexts, and execution backends.
CLI Overview
Submit runs and manage Platform resources from a workspace repository.
Platform Onboarding
Create your workspace, connect its repository, and authenticate the CLI.
Multiply Quickstart
Use the Platform path to run a known-good evaluation and submit training.
Changelog

Use Cases
Data Extraction
Build domain-specific extraction models to capture the exact structure and content for any document at a fraction of the cost of a foundation model or managed product.
Tool Use
Teach AI agents to use the exact tools they’ll have in production. Osmosis powers AI agents that stay reliable, even in the most complex multi-step, multi-tool tasks.
Code Generation
Train specialized coding models for blazing fast generation of domain-specific languages, front-end components, and tests — without needing a large model.
Why Osmosis
AI Agent Post-Training
Osmosis ships primitives and tool modules into the platform so coding agents like Claude Code, Codex, and others can start, monitor, and iterate on training runs.
Reinforcement Fine-Tuning
Osmosis implements and handles the RL algorithms and infrastructure that enable performant, GPU-efficient training runs.
Continuous Improvement
Osmosis integrates with your evaluation solutions and coding agents to automatically start re-training runs without the need for an engineer in the loop.
