Recursive

AI research lab behind Flint, an open-weights local coding model, and a system that automates AI research.

Open source

What is Recursive?

Recursive is an AI research company, incorporated as Recursive Superintelligence, Inc., with offices in San Francisco and London. Its stated aim is software that improves its own AI research, and it uses an internal system called the Eureka Machine to propose, implement and test research ideas. Its first public model is Flint, a mixture-of-experts model for agentic coding on local hardware, with 40 billion total parameters and 2.5 billion active per token. The weights are on Hugging Face under the Apache 2.0 license, so you can run Flint on your own machine, keep data local and avoid API fees. It works with llama.cpp, Ollama, Unsloth, LM Studio, vLLM and SGLang, and Recursive also released rec, a small inference engine tuned for Flint on recent Apple chips. Recursive also operates hosted APIs and a developer console, but no price list is published.

Use cases

  • Run a coding model locally
  • Use an agentic coding assistant offline
  • Fine-tune an open-weights model
  • Serve a model with vLLM or SGLang
  • Keep source code on your own machine
  • Study automated AI research methods

Who it's for

  • Developers
  • AI researchers
  • ML engineers
  • Privacy-conscious teams

Why use Recursive

  • Open weights let you run and adapt the model yourself
  • Local use keeps your code and data on your own device
  • No per-token API fees when you run Flint on your hardware
  • Works with several popular local inference tools

How to get started with Recursive

  1. Download the Flint weights from Hugging Face.
  2. Load them in a supported runtime such as Ollama, LM Studio, llama.cpp, vLLM or SGLang, or use the rec engine on a recent Mac.
  3. Use it as a local coding model, giving explicit instructions and splitting larger work into subtasks.
  4. Adapt the model for your own applications under the Apache 2.0 license.

Recursive limitations

  • The terms say inputs and outputs sent to the hosted API may be used to train Recursive's models
  • The vendor advises breaking complex tasks into smaller subtasks for Flint
  • Hosted offerings may be free, pre-release or paid and can change or end at any time

Recursive pricing

Recursive is open source, so you can use and self-host it for free.

Prices can change and may vary by country or exclude tax. Check the official pricing page.

Recursive FAQ

How much does Recursive cost?

The Flint weights are free to download under Apache 2.0. Recursive does not publish prices for hosted services, and its terms say some services are free, some pre-release and some paid.

Is Flint open source?

Flint's weights are released under the Apache 2.0 license on Hugging Face. Recursive says open-source releases are governed by their license rather than its general terms.

Can I run Flint locally?

Yes. It works with llama.cpp, Ollama, Unsloth, LM Studio, vLLM and SGLang, and Recursive offers rec, an inference engine optimized for recent Apple chips.

Does Recursive have an API?

Its terms describe hosted APIs, a developer console and hosted models. They also state that inputs and outputs on the hosted API can be used for training, so avoid sending sensitive data.

What are alternatives to Recursive?

For local coding models, alternatives include Qwen Coder, DeepSeek Coder, Mistral's Codestral and Meta's Llama models. On Debuly, compare Ollama, LM Studio and Rapid-MLX.
