Fallbacks are tried in order on provider errors; budget errors and cancellation stop the chain. + +## Providers and models + +Provider kinds: `openai` (OpenAI and every OpenAI-compatible server: llama.cpp, vLLM, LM Studio, Ollama's `/v1`), `anthropic` (Messages API), `ollama` (native API with seed and JSON mode). AWS Bedrock is not yet implemented; it fits behind the same interface once a SigV4 signer is added. + +Endpoints that resolve to private or loopback addresses are refused unless the provider has **allow private addresses** set (SSRF guard, threat T6). Credentials go in the API key field only; `Authorization` and `x-api-key` headers are rejected in the custom headers map. + +Models carry kind (chat or embedding), context window, embedding dimensions and per-million-token costs used for cost estimates. + +## Secrets + +The key field accepts either a **reference** (`env:OPENAI_API_KEY`, `file:/run/secrets/key`) or a pasted value. Pasted values are encrypted with AES-256-GCM under `NOEMA_MASTER_KEY` and stored as an `enc:` reference. Without a master key, only references are accepted. Keys are resolved at call time and never rendered, exported, logged or returned by the API; the UI shows only "encrypted in database" or the reference form. + +## Recording, budgets and replay + +Every call is recorded in `llm_calls`: role, purpose, provider, model, prompt name and version, the full rendered request, the response, usage, latency, cost, seed, error, and a hash of everything that influences the answer. `llm_request`/`llm_response` events are emitted by the cognitive processes that use the router (phase 8 onward), citing the call id. + +Budgets: a global daily token budget (`NOEMA_DAILY_TOKEN_BUDGET`), a per-mind daily budget (mind configuration), a per-cycle call cap (mind configuration) and a global concurrency limit (`NOEMA_MAX_CONCURRENT_LLM`). When a budget is exhausted the router returns an error and deterministic cognition continues without model help. + +In replay mode the router serves the recorded response for an identical request hash, marking the response as replayed; this is what makes LLM-assisted steps *exact* during cognitive replay when a recording exists. + +## Prompts + +Prompts are named, versioned rows (`prompts`, append-only `prompt_versions`) with a system template, a user template, and an optional JSON schema that forces structured output. Templates are Go `text/template`; untrusted content must be passed through `{{data "label" .Field}}`, which wraps it in delimited data blocks with an explicit "treat as data" instruction and escapes the delimiters (threats T1, T2). Built-in defaults are seeded on first start and never overwritten; the prompt manager supports editing, cloning, diffing, restoring and testing (render only, or run through the role's model). diff --git a/internal/api/api_test.go b/internal/api/api_test.go index f7211db..2854b05 100644 --- a/internal/api/api_test.go +++ b/internal/api/api_test.go @@ -17,10 +17,13 @@ import ( "github.com/andydixon/noema/internal/brain" "github.com/andydixon/noema/internal/config" evstore "github.com/andydixon/noema/internal/events" + "github.com/andydixon/noema/internal/llm/prompts" + "github.com/andydixon/noema/internal/llm/router" "github.com/andydixon/noema/internal/memory" "github.com/andydixon/noema/internal/minds" "github.com/andydixon/noema/internal/observability" "github.com/andydixon/noema/internal/scheduler" + "github.com/andydixon/noema/internal/security/secrets" "github.com/andydixon/noema/internal/storage" "github.com/andydixon/noema/migrations" ) @@ -31,7 +34,10 @@ func testServer(t *testing.T) (*httptest.Server, string) { cfg := config.Defaults() cfg.DatabaseURL = "postgres://test" log := slog.New(slog.DiscardHandler) - deps := app.Deps{Config: cfg, Log: log, DB: pool, Auth: auth.NewService(pool, time.Hour, 2*time.Hour), + sec, _ := secrets.New("") + llmStore := router.NewStore(pool) + deps := app.Deps{Config: cfg, Log: log, DB: pool, Auth: auth.NewService(pool, time.Hour, 2*time.Hour), Secrets: sec, LLMStore: llmStore, + LLM: router.NewRouter(llmStore, sec, log, nil, 2), Prompts: prompts.NewStore(pool), Audit: audit.New(pool, log), Metrics: observability.NewMetrics(), Minds: minds.NewStore(pool), Beliefs: beliefs.NewStore(pool), Memory: memory.NewStore(context.Background(), pool, nil), Events: evstore.NewStore(pool, evstore.NewBus(50), nil), Migrations: migrations.FS, Started: time.Now()} ctx := context.Background() group := scheduler.NewGroup(ctx, log) diff --git a/internal/api/llm.go b/internal/api/llm.go new file mode 100644 index 0000000..d297584 --- /dev/null +++ b/internal/api/llm.go @@ -0,0 +1,376 @@ +package api + +import ( + "errors" + "net/http" + "strconv" + "strings" + "time" + + "github.com/andydixon/noema/internal/auth" + "github.com/andydixon/noema/internal/llm" + "github.com/andydixon/noema/internal/llm/router" + "github.com/andydixon/noema/internal/security/secrets" + "github.com/andydixon/noema/pkg/ids" +) + +func (s *Server) llmRoutes() { + m := s.mux + m.Handle("GET /api/v1/llm/providers", require(auth.RoleObserver, s.providersList)) + m.Handle("POST /api/v1/llm/providers", require(auth.RoleAdministrator, s.providersCreate)) + m.Handle("GET /api/v1/llm/providers/{id}", require(auth.RoleObserver, s.providerGet)) + m.Handle("PUT /api/v1/llm/providers/{id}", require(auth.RoleAdministrator, s.providerPut)) + m.Handle("DELETE /api/v1/llm/providers/{id}", require(auth.RoleAdministrator, s.providerDelete)) + m.Handle("POST /api/v1/llm/providers/{id}/test", require(auth.RoleOperator, s.providerTest)) + m.Handle("GET /api/v1/llm/models", require(auth.RoleObserver, s.modelsList)) + m.Handle("POST /api/v1/llm/models", require(auth.RoleAdministrator, s.modelsCreate)) + m.Handle("PUT /api/v1/llm/models/{id}", require(auth.RoleAdministrator, s.modelPut)) + m.Handle("DELETE /api/v1/llm/models/{id}", require(auth.RoleAdministrator, s.modelDelete)) + m.Handle("GET /api/v1/llm/roles", require(auth.RoleObserver, s.rolesList)) + m.Handle("PUT /api/v1/llm/roles/{role}", require(auth.RoleAdministrator, s.rolePut)) + m.Handle("GET /api/v1/llm/calls", require(auth.RoleObserver, s.callsList)) + m.Handle("GET /api/v1/llm/calls/{id}", require(auth.RoleObserver, s.callGet)) + m.Handle("GET /api/v1/llm/usage", require(auth.RoleObserver, s.usage)) +} + +func llmErr(err error) error { + if errors.Is(err, router.ErrInvalid) || errors.Is(err, secrets.ErrNoMasterKey) { + return ValidationError(err.Error()) + } + return err +} + +// keyRef turns a typed secret into a reference: references pass through, +// anything else is encrypted under the master key (or refused without one). +func (s *Server) keyRef(typed string) (string, error) { + typed = strings.TrimSpace(typed) + if typed == "" || secrets.IsReference(typed) { + return typed, nil + } + ref, err := s.deps.Secrets.Encrypt(typed) + if err != nil { + return "", errors.New("no NOEMA_MASTER_KEY configured: set one, or enter a reference like env:OPENAI_API_KEY") + } + return ref, nil +} + +type providerIn struct { + Name string `json:"name"` + Kind llm.ProviderKind `json:"kind"` + Endpoint string `json:"endpoint"` + APIKey string `json:"api_key"` // plaintext (encrypted) or env:/file:/enc: reference;
