From Aktagon

The LLM client Aktagon built to power its agents. In Go, TypeScript, Python, and Rust.

llmkit is the kit Aktagon built so its agents can talk to any provider, in any language, without three different bug surfaces. Polyglot teams get one mental model. Single-language teams get an SDK that doesn't lag behind a reference implementation. Same wire-level tests. Same release cadence.

// One client. Four languages. Identical surface.
client := llmkit.New(llmkit.Anthropic, key)

resp, err := client.Prompt(ctx, llmkit.Request{
    Model: "claude-sonnet-4-5",
    Messages: []llmkit.Message{
        llmkit.User(llmkit.Text("Plan the next sprint.")),
    },
})

// resp.Text — provider-agnostic. Stream, batch, tools, caching, images: same shape.

Same API. · Zero dependencies. · 27 providers.
