Disclaimer of Liability + +Except in the cases of wilful misconduct or damages directly caused to natural +persons, the Licensor will in no event be liable for any direct or indirect, +material or moral, damages of any kind, arising out of the Licence or of the use +of the Work, including without limitation, damages for loss of goodwill, work +stoppage, computer failure or malfunction, loss of data or any commercial +damage, even if the Licensor has been advised of the possibility of such damage. +However, the Licensor will be liable under statutory product liability laws as +far such laws apply to the Work. + +9. Additional agreements + +While distributing the Work, You may choose to conclude an additional agreement, +defining obligations or services consistent with this Licence. However, if +accepting obligations, You may act only on your own behalf and on your sole +responsibility, not on behalf of the original Licensor or any other Contributor, +and only if You agree to indemnify, defend, and hold each Contributor harmless +for any liability incurred by, or claims asserted against such Contributor by +the fact You have accepted any warranty or additional liability. + +10. Acceptance of the Licence + +The provisions of this Licence can be accepted by clicking on an icon ‘I agree’ +placed under the bottom of a window displaying the text of this Licence or by +affirming consent in any other similar way, in accordance with the rules of +applicable law.

It is the single home for everything needed to run a local model: the shared contract (`TextModel`, `Backend`, and supporting types), the GPU compute engines that implement it, the serving layer that exposes them over HTTP, and the `lem` binary that ties it together. -Module path: `dappco.re/go/inference` +Historically this was a contract-only package that GPU backends in separate repositories (`go-mlx`, `go-rocm`) implemented.

If none of the preferred backends are available, any registered backend reporting `Available() == true` is used. With nothing registered, `Default()` returns a failed Result (`no backends registered`); with backends registered but none available, `no backends available`. ### LoadModel routing `LoadModel` is the primary consumer entry point. It resolves the backend then delegates: ```go -// Explicit backend -m, err := inference.LoadModel("/path/to/model/", inference.WithBackend("rocm")) +// Explicit backend (bypasses Default()) +r := inference.LoadModel("/models/model.gguf", inference.WithBackend("rocm")) // Auto-detect (uses Default()) -m, err := inference.LoadModel("/path/to/model/") +r := inference.LoadModel("/models/gemma-4-e2b-it-4bit") +if !r.OK { + log.Fatal(r.Error()) +} +m := r.Value.(inference.TextModel) ``` -When `WithBackend()` is set, `LoadModel` looks up the named backend directly and returns an error if it is not registered or not available.

This helper clears the map and is defined in `inference_test.go`: - -```go -func resetBackends(t *testing.T) { - t.Helper() - backendsMu.Lock() - defer backendsMu.Unlock() - backends = map[string]Backend{} -} ``` -Because `resetBackends` is in the `inference` package (not `inference_test`), it has direct access to the unexported `backends` map. Tests must not rely on registration order across test functions; each test that uses the registry must call `resetBackends` at the top. - -### Stub Implementations - -`inference_test.go` provides `stubBackend` and `stubTextModel` — minimal implementations of `Backend` and `TextModel` for use in registry and routing tests. These are in the `inference` package itself (not a separate `_test` package) to allow access to unexported fields. - -When writing new tests, use the existing stubs rather than creating new ones unless you need behaviour the stubs do not support. - -### Table-Driven Tests - -Prefer table-driven tests for options and configuration variants.

After adding or +changing module dependencies: -UK English throughout: colour, organisation, centre, licence (noun), serialise, recognise. American spellings are not accepted in comments, documentation, or error messages. - -### Formatting - -Standard `gofmt` formatting. No custom style rules. Run `gofmt -w .` or `go fmt ./...` before committing. - -### Error Messages - -Error strings start with the package name and a colon, lowercase, no trailing period: - -```go -fmt.Errorf("inference: no backends registered (import a backend package)") -fmt.Errorf("inference: backend %q not registered", cfg.Backend) -fmt.Errorf("inference: backend %q not available on this hardware", cfg.Backend) -``` - -This convention matches the Go standard library and makes `errors.Is`/`errors.As` wrapping straightforward. - -### Strict Types - -All parameters and return types are explicitly typed. No `interface{}` or `any` outside of test helpers where unavoidable. - -### Dependencies - -No new external dependencies may be added to the production code. The `go.mod` `require` block must remain stdlib-only for non-test code. `testify` is the only permitted test dependency. - -If you find yourself wanting an external library, reconsider the approach.
