Tinker is Thinking Machines AI’s model training API platform for researchers and developers, focused on fine-tuning large language models. It provides fine-grained control over training while the platform manages the underlying compute infrastructure.
The platform supports multiple mainstream open-source LLMs, including Llama 70B and Qwen 235B, and vision-language models like Qwen3‑VL. Users can switch models by modifying their code.
Tinker is aimed at researchers and developers with machine learning experience. Users typically write training logic in Python, while the platform takes care of distributed training and hardware management.
Public information indicates the platform was in a testing stage and offered free credits. Future billing is likely to be based on compute, storage and API usage. For exact pricing details, consult the official announcements.
The company provides legal and privacy frameworks, including terms of service. For specifics on data handling and security measures, refer to the official privacy policy and service terms.
The platform is primarily designed for scenarios that require deep model customization and is best suited for users with ML fundamentals. Beginners are advised to learn core concepts before using the platform.
Yes. The company runs community project calls and offers research and teaching grants, providing compute credits or funding to qualifying academic projects, open-source efforts, or courses.
Tinker’s main distinction is its level of control: it exposes low-level primitives that let users define custom training algorithms, while the platform handles complex distributed systems management to separate algorithm development from infrastructure operations.
Together AI is an AI-native cloud platform that provides developers and enterprises with full-stack infrastructure to build and run generative AI applications. The platform offers end-to-end tooling for obtaining models, customizing, training, and high-performance deployment, aiming to accelerate AI app development and optimize cost efficiency.
Lightning AI is an integrated AI development platform built by the founding team of PyTorch Lightning, providing cloud development environments and elastic computing resources to help developers efficiently build, train, and deploy AI models.
