Hey folks 👋 (sorry for the newbie question),
Is there any model with a free tier where we can experiment with tools? ie ToolRegistry { tool(SayToUser) }
For example, Gemini Flash throws an exception saying tools are not supported for that model; and Gemini Pro does not have a free tier.

Hi! I think you can try Ollama, for example. llama3 supports tools (though, you have to use the version of Koog from develop — will be released in a week from now.
tool calls with Ollama behaviour must have been fixed by this commit — https://github.com/JetBrains/koog/pull/344 )

Pretty cool! Thank you so much

Also I made it previously working with Gemini for me (with a free model), but don’t remember exact model

Gemini 2.5 flash can call tool, you can create a model like

LLModel(
    provider = LLMProvider.Google,
    id = "gemini-2.5-flash",
    capabilities = listOf(
        LLMCapability.Temperature,
        LLMCapability.Schema.JSON.Full,
        LLMCapability.Completion,
        LLMCapability.Tools
    ) + listOf(
        LLMCapability.Vision.Image,
        LLMCapability.Vision.Video,
        LLMCapability.Audio
    )
)

We also have an OpenRouter client, which can provide you access to some free models 🙂
