sigma-evals

sigma-evals is a small Go SDK for provider-neutral LLM evaluation on top of Sigma. It gives applications portable eval contracts, runners, scorers, judges, and result records without forcing a hosted service, dataset format, UI, or persistence layer.

Use it when you want the same suite to run against several model providers, agent runtimes, or saved outputs, while keeping the scoring and result shape stable.

Status

Public preview. The module builds from a fresh clone and pins Sigma v0.5.1-0.20260615130520-726f3bbb781f in go.mod; there is no local replace dependency.

Quick start

Run the bundled smoke examples without provider credentials:

git clone https://github.com/benjaminwestern/sigma-evals.git
cd sigma-evals
mise run ci

Use it from another Go module:

go get github.com/benjaminwestern/sigma-evals

Run the example CLI directly:

go run ./cmd/sigma-evals smoke-examples \
  --examples examples \
  --out runs/examples-smoke.json

Run one suite against a real Sigma target:

go run ./cmd/sigma-evals run-suite \
  --suite examples/generic/answer-aliases.json \
  --target fireworks=accounts/fireworks/routers/kimi-k2p6-turbo \
  --out runs/answer-aliases.json

Judge an existing output through the same target seam:

go run ./cmd/sigma-evals judge-output \
  --judge openai=gpt-4o \
  --target-output "Bonjour" \
  --ground-truth "Bonjour" \
  --rubric "Grade exact translation correctness."

What it provides

  • A portable Suite / Case / Expected JSON model for text, multimodal chat/image-input, multiple-choice, JSON, and tool-call evals.
  • SDK runners for direct Sigma models, caller-provided targets, raw fanout, and scoring existing outputs without regenerating completions.
  • Provider-neutral error classification in result records using Sigma's typed auth, quota, billing, rate-limit, transient, context-overflow, invalid-request, and provider error classes.
  • Deterministic scorers for exact, normalised, contains, regex, JSON structure, token F1, multiple choice, pass@k, and expected tool calls.
  • LLM-as-judge helpers for strict JSON judges, pairwise judging, G-Eval score-token weighting, batch judging, and weighted rubric scoring.
  • Built-in single-prompt rubrics for accuracy, helpfulness, persona drift, conciseness, and JSON strictness.
  • Variance reports and baseline/current comparisons across suite runs, batch judges, and judge alignment so repeated evals can separate model drift from sampling noise.
  • Judge-alignment evaluation with regression, classification, calibration, and tolerance metrics against labelled examples.
  • Small CLI consumers under cmd/ plus working JSON examples under examples/ for local smoke tests and integration reference.

How it fits together

The main seam is TargetCompleter. Apps can plug in direct Sigma calls, agent runtimes, local models, CI jobs, or saved runtime traces while sigma-evals handles rendering, repeats, concurrency, scoring, aggregation, and result records.

type TargetCompleter interface {
    CompleteTarget(context.Context, sigmaevals.TargetRequest) (sigmaevals.TargetResult, error)
}

For direct Sigma use, adapt a Sigma client:

runner := sigmaevals.NewTargetRunner(
    sigmaevals.NewSigmaTargetCompleter(sigma.NewClient()),
)

result, err := runner.Run(ctx, sigmaevals.TargetRunSpec{
    Suite: suite,
    Targets: []sigmaevals.Target{{
        Provider: sigma.ProviderFireworks,
        ModelID:  "accounts/fireworks/routers/kimi-k2p6-turbo",
    }},
    Scorers: []sigmaevals.Scorer{sigmaevals.AutoScorer{}},
})

LLM judges use the same seam, so agent runtimes do not need to pretend to be a sigma.Client:

evaluator := sigmaevals.NewTargetEvaluator(myTargetCompleter)

judge, err := evaluator.Judge(ctx, sigmaevals.JudgeInput{
    TargetOutput:  generatedAnswer,
    GroundTruth:   "Bonjour",
    Rubric:        "accuracy", // or any custom rubric prompt
    Judge:         sigmaevals.Target{Provider: "agent-runtime", ModelID: "judge"},
    Mode:          sigmaevals.ModeGEval,
    PassThreshold: 4.0, // optional; defaults to 3 on the 1-5 G-Eval scale
})

Batch judging is also SDK-owned through the same target-completer seam:

batch, err := evaluator.EvaluateBatch(ctx, sigmaevals.BatchJudgeSpec{
    Name:         "translation-regression",
    Target:       sigmaevals.Target{Provider: "agent-runtime", ModelID: "worker"},
    Judge:        sigmaevals.Target{Provider: "agent-runtime", ModelID: "judge"},
    Rubric:       "accuracy",
    TargetPrompt: "Answer directly.",
    Cases: []sigmaevals.JudgeCase{{
        ID:          "hello-fr",
        Input:       "Translate hello to French.",
        GroundTruth: "Bonjour",
    }},
})

Example suites

Working JSON suites live in examples. They are intentionally small showcases, not serious model-quality benchmarks.

  • examples/generic demonstrates closed-answer alias matching, negative-answer rejection, and needle retrieval.
  • examples/chat demonstrates single-turn JSON extraction, multi-turn context recall, and image-input rendering.
  • examples/choice demonstrates multiple-choice selected-label scoring.
  • examples/tools demonstrates expected tool-call evaluation by tool name and JSON arguments.

CLI consumers

The CLIs under cmd are reference consumers of the SDK interfaces, not a hosted product surface.

  • cmd/sigma-evals runs local smoke examples, real suites against Sigma targets, one-off LLM judge checks, batch judging, judge alignment, built-in rubric listing, variance reports, and baseline/current variance comparisons. It can render command outputs as JSON, JSONL, or Markdown via --format, registers the common Sigma text providers plus OpenAI/OpenRouter image providers, and exposes --session-id / --cache-retention flags for provider affinity and prompt-cache-enabled runs.
  • cmd/sigma-evals-live is an optional live harness for provider-backed needle and tool-calling checks. It requires FIREWORKS_API_KEY and OPENCODE_API_KEY.

Scoring methods

The core package covers:

  • deterministic single-output scoring
  • multiple-choice and JSON/schema-style output scoring
  • single-turn and multi-turn chat evaluation
  • tool-call and full-trace-aware scoring
  • reference-answer judging
  • strict JSON LLM-as-judge
  • pairwise LLM judging with swapped-order consistency checks
  • single-score G-Eval and multi-metric rubric G-Eval
  • judge-alignment evaluation
  • pass@k aggregation for sampled or code-style tasks
  • scoring existing outputs without rerunning target models

Variance and baseline comparison

Run repeated evals with the existing --repeat and --concurrency flags, then build variance reports over the result rows:

today := sigmaevals.VarianceReportFromRunResult(todayRun)
tomorrow := sigmaevals.VarianceReportFromRunResult(tomorrowRun)
comparison := sigmaevals.CompareVarianceReports(today, tomorrow, sigmaevals.VarianceCompareOptions{})

The same comparison layer works for BatchJudgeResult and JudgeAlignmentRunResult. Normalized samples can be persisted as JSONL with WriteVarianceSamplesJSONL / ReadVarianceSamplesJSONL.

Judge-alignment example

alignment, err := sigmaevals.NewTargetEvaluator(
    sigmaevals.NewSigmaTargetCompleter(client),
).EvaluateJudges(ctx, sigmaevals.JudgeAlignmentSpec{
    Name:         "judge-alignment-smoke",
    JudgeTargets: []sigmaevals.Target{sigmaevals.TargetFromModel(judgeModel)},
    Tolerance:    0.5,
    Cases: []sigmaevals.JudgeAlignmentCase{
        {
            ID:             "correct-answer",
            Input:          "Translate hello to French.",
            TargetOutput:   "Bonjour",
            GroundTruth:    "Bonjour",
            Rubric:         "Grade exact correctness.",
            ExpectedScore:  1,
            ExpectedPassed: true,
        },
    },
})

EvaluateJudges reports MAE, MSE, RMSE, Pearson correlation, Spearman correlation, accuracy, precision, recall, F1, balanced accuracy, Cohen's kappa, Brier score, and tolerance accuracy.

Documentation

Overview

Package sigmaevals provides a small provider-neutral evaluation SDK core on top of Sigma.

The package owns portable eval contracts and repeatable mechanics: rendering cases into sigma.Request values, running the same cases across caller-provided targets, applying deterministic scorers or TargetCompleter-backed LLM judges, batch-judging target or saved outputs, testing judges against labelled examples, comparing repeated-run variance across eval layers, and returning portable result records. It intentionally does not own third-party datasets, hosted leaderboards, app persistence, UI, or daemon/session lifecycle.
