Recursive releases Flint and an inference engine for local coding agents

Its mixture-of-experts design activates about 2.5 billion parameters per token; runtime choice and hardware still determine the experience.

Recursive has released Flint, a coding model intended to run on local hardware, alongside its specialised rec inference engine. The October 21 release describes a mixture-of-experts design with roughly 40 billion total parameters and about 2.5 billion active for each token.

The weights are available under Apache 2.0. Recursive says its Eureka Machine automated research system helped develop the model’s training and inference stack. That is the company’s account of its development process, rather than an independent assessment of how much work the system replaced.

The checkpoint and runtime matter

The model card lists 262,144 tokens in its documented context configuration. The launch page describes support up to 512K while recommending staying within 256K for better results. These are capacity statements, not a guarantee of equal accuracy at every length.

Recursive publishes coding benchmark results and speeds on selected hardware. The practical outcome depends on the checkpoint precision, inference engine, memory and task. A laptop demonstration should not be generalised to every device.

Local access changes the operating model

Running a coding model locally can keep prompts and source files on the user’s machine. It also makes the operator responsible for the execution environment and the permissions given to tools.

A useful evaluation would follow a real issue through investigation, edits and validation of the finished change. Incorrect code can still look convincing, and a locally hosted agent can still make consequential mistakes.

Flint offers another route for that work, with downloadable weights and a documented serving path. Its suitability depends on the complete coding workflow rather than active parameter count alone.
