Go Attention

Go Attention is a public MIT-licensed Go library that implements attention mechanisms and transformer layers without external dependencies. Its documented components include dot-product attention, configurable multi-head attention and a transformer layer with self-attention and a feed-forward network.

Practical overview

When it fits

Use it when an AI application is already being built in Go and needs documented attention or transformer-layer components without introducing an external dependency stack.

Who it is for

  • Go developers building AI or machine-learning applications
  • Teams adding transformer components to Go services
  • Developers creating self-hosted inference or experimentation tools
  • Builders targeting edge-oriented or single-binary Go deployments

Documented uses

  • Compute dot-product attention from query, key and value data
  • Process batched inputs with multi-head attention
  • Add a transformer layer to a Go application
  • Keep attention functionality within a pure-Go, zero-dependency deployment
Before you choose

Requirements & limits

The repository is public and accessible, and the library is identified as open source under the MIT license. The documented setup uses Go module tooling. No pricing or account requirement is provided.

  • The implementation is written in Go and exposes Go vector and matrix types.
  • The documented design has zero external dependencies and supports single-binary deployment scenarios.
  • Available components range from dot-product attention to multi-head attention and a full transformer layer.
  • The README describes SIMD-related optimized paths, fallbacks, goroutine parallelization and allocation optimizations.
  • The library is a building block; the surrounding application must provide suitable inputs and the broader inference or training workflow.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add attention components to a Go project

Set up the library and choose a documented attention or transformer component.

Before you start

  • A Go development environment
  • A Go-compatible platform
  • Application data that can be represented as the documented vectors or matrices

Steps

  1. Fetch the module with the command below.

    Documented command
    go get github.com/takara-ai/go-attention

  2. Run the documented examples with the command below.

    Documented command
    go run api_examples.go

  3. For basic sequence processing, create query, key and value vectors or matrices and call attention.DotProductAttention.

  4. For a larger component, configure attention.MultiHeadConfig or transformer.TransformerConfig and construct the corresponding module.

  5. Pass the prepared matrices to the documented Forward method.

Expected outcome

A Go project is set up to use the library's documented attention or transformer interfaces.

Guide limitations

  • The examples document component setup and invocation, but do not describe model training, tokenization, full application deployment or production integration.
  • Performance figures in the README are project-reported benchmark results rather than an independent test.
