What Are Common Questions About Thinking Machines Lab?

Distributed GPU Infrastructure For Fine-Tuning LLMs — Tinker is a training API from Thinking Machines Lab that provides distributed GPU infrastructure for fine-tuning large language models (LLMs). You write simple Python scripts that utilize four core primitives (forward_backward, optim_step, sample, save_state) and Tinker takes care of the distributed training of multiple GPUs.

Supports Many Large Language Models — supports a variety of open-source models, such as Llama 70B, Qwen 235B, Qwen3-8B, and Llama-3.2-1B. Changing the base model requires changing only one string in your script.

First, you need to install the software using pip install tinker. Next, create an API Key using the Tinker Console. After that, set the TINKER_API_KEY as an environment variable. Finally, start by using some example cookbooks available on GitHub. The Tinker Console is able to monitor every single one of your training runs.

Tinker takes care of all of the complexities of setting up the underlying infrastructure (distributed GPUs, hardware failure, etc.) so you can focus solely on developing the algorithms and working with the data. The team at Tinker will take care of the bulk of the work to scale your training up to 100+ GPUs.

Tinker allows you to process your custom training data via API calls while still allowing you to have total control over how your data is processed and how your algorithms are executed. While there are certain security certifications that have been issued for Tinker, this information has not been made publicly available.

The four fundamental primitives in Tinker are: • forward_backward (computes the gradient) • optim_step (updates the parameter values) • sample (generates tokens) • save_state (creates a checkpoint of the current state of the training) These primitives allow you to perform the entire fine-tuning workflow.

Yes, Tinker does support both save_state and load_state to be used for checkpointing both the weight values and the optimizer state. The Tinker Console also tracks each run of the training and provides the option to resume training from the most recent saved state.

Some examples of what you can do with Tinker include: • Fine-tune a large language model for answering financial questions • Train tools to follow instructions • Distill prompts into their simplest form • Optimize multiple agents using LLMs GitHub has several complete implementations of these different use cases in its cookbook.

Is Thinking Machines Lab Worth It?

Thinking Machines Lab's Tinker is a major innovation in making it easier to fine-tune large language models (LLMs) by abstracting away the complex work involved with training across many GPUs, while still providing users with the flexibility to implement custom models. In October of 2025, Mira Murati's lab released Tinker to target researchers and developers who want to train production-quality models but don't have the infrastructure expertise to do so. The four primitive API makes it much easier to fine-tune custom models.

Recommended For

  • Researchers who are fine-tuning their own custom datasets on very large models (70B+).
  • Teams which lack the necessary expertise to set up a distributed GPU infrastructure.
  • Developers creating specialized LLMs for applications such as finance, tool use, or agents.
  • Organizations that want to retain control over their training algorithms without having to deal with the operational overhead. The above list of items has been revised to better reflect the user experience. The revision process was focused on changing word choice and sentence structure to create a more natural flow of language while maintaining the same information.

!
Use With Caution

  • Currently LoRa-focused, full-fine tuning users - planned in future.
  • Distributed GPU pricing is not publicly available for cost-sensitive teams.
  • Production inference at scale - primarily API focused on training.
  • Users with no prior experience with the training loop.

Not Recommended For

  • Needs for simple prompt engineering - overkill for most users' basic use of an LLM.
  • Hobbyist budget constrained - costs are for enterprise-class infrastructure.
  • Training on-premises - fully cloud-based.
Expert's Conclusion

Tinker is suitable for serious AI researchers that require distributed training capabilities without the infrastructure issues, greatly simplifying large-scale LLM fine-tuning.

Best For
Researchers who are fine-tuning their own custom datasets on very large models (70B+).Teams which lack the necessary expertise to set up a distributed GPU infrastructure.Developers creating specialized LLMs for applications such as finance, tool use, or agents.

What Are the Best Alternatives to Thinking Machines Lab?

  • •
    OpenAI Fine-tuning API: Provides a way to easily fine-tune GPT models using a simple API compared to using Tinker. While significantly easier than Tinker, its scope is limited to OpenAI models and does not provide as much algorithmic control. Ideal for Teams requiring easy-to-use GPT-4o-mini customizations that do not require managing their own infrastructure. (platform.openai.com)
  • •
    Together AI Fine-tuning: A Cloud Fine-Tuning Platform that supports open models with more managed services than Tinker. Has less low-level control than Tinker, but is generally easier to use for those that are not experienced with AI development. Provides both training and production endpoint options for Teams that require both. (together.ai)
  • •
    Fireworks AI: A serverless inference + fine-tuning platform with a wide variety of model support. More costly, but fully-managed and requires less developer effort to implement. Ideal for Teams that prefer ease-of-use over fine-grained control of the training process. (fireworks.ai)
  • •
    Replicate: Git based workflow model hosting + fine tuning. More of a general purpose than Tinker's training focused on deploying & iterating on models w/minimal ops. replicate.com
  • •
    Self-hosted (vLLM + Ray): A full control training stack using Ray clusters on your own GPUs. The most flexible option but you will require significant DevOps expertise that Tinker removes. Good fit for teams already running their own GPU infrastructure & have ops expertise.
