Overview
Flint is an open-weight mixture-of-experts model from Recursive, with about 2.5B active parameters out of 40B total, built by Recursive's autoresearch system Eureka Machine for coding agents. It is suited...
Our take
For developers building coding agents, Flint offers a model with built-in reasoning and tool-calling capabilities. Unlike generalist chatbots such as Claude or ChatGPT, this model is specifically positioned for agent-style workflows, supporting function calling and a 262,144-token context window. Its integrated chain-of-thought mode aims to address more complex problems. The model is free to use via the OpenRouter API, which differentiates it from commercial alternatives like Gemini or MiniMax M3.1 Flash. However, it is a text-only model and does not process image input. It is ideal for users who require a dedicated AI assistant for coding tasks, particularly those needing to implement tool-use or extensive context. For those seeking a no-cost, agent-focused AI model for coding, this could be a suitable option.

Among the 380 chatbots & llms tools in our directory, it ranks #205 of 375 on quality (7.8/10), 3% below the 375-tool average of 8.1, and it's one of the free-to-use options in the category.
Recursive: Flint in depth
Recursive: Flint, built by Recursive, sits in the chatbots & llms space and is completely free to use. Our editors rate it 7.8 out of 10 based on capability, ecosystem and value. It handles a context window of 262,144 tokens.
