AI model development

Make the model earn its place in the system.

Werkon develops or adapts models only when the task, data, and operating context justify it. Every candidate is compared with a simpler baseline, evaluated on protected cases, documented by segment and limitation, and packaged for reproducible release.

Development contract

Connect the task, dataset, candidate, and consequence.

The development boundary includes the real decision, a useful non-model or existing-model baseline, the full data lineage, protected evaluation cases, model and system constraints, downstream controls, and the people accountable for release.

Inputs

Task and consequence
Intended users, decision or output, unit of analysis, operating context, current method, errors, downstream action, affected parties, human role, risk tolerance, and the measure that would justify change.
Dataset and rights
Sources, ownership, permission, licenses, consent, sensitivity, provenance, collection process, time range, labels, missingness, imbalance, duplication, representation, retention, and deletion obligations.
Baseline and model constraints
Rules, heuristics, existing services, prompted or retrieved approaches, quality targets, uncertainty, explainability, robustness, privacy, compute, latency, throughput, cost, portability, and provider limits.
Evaluation and operation
Development and protected holdout splits, segment and difficult cases, acceptance thresholds, human review, abuse cases, monitoring, feedback, retraining triggers, versioning, rollback, incident response, and retirement ownership.

Outputs

Dataset dossier
Versioned sources, rights, provenance, collection and labeling methods, schema, transformations, exclusions, known gaps, splits, leakage checks, segment coverage, access, retention, and reproducible preparation code.
Baseline ladder
Comparable evidence for the current method, deterministic rules, available services, prompt or retrieval approaches, adapted candidates, and new training where justified.
Reproducible model artifact
Versioned code, configuration, dependencies, data references, training or adaptation procedure, random seeds where relevant, model weights or provider version, checksums, environment, and artifact registry record.
Evaluation and release pack
Protected results by task and segment, uncertainty, failure analysis, adversarial and misuse evidence, limitations, human-review load, cost and latency observations, approval, deployment contract, monitoring, rollback, and retirement criteria.

Model path

Protect the comparison from the start.

The evaluation set, release measures, and simpler alternatives are defined before candidate tuning. This keeps the team from optimizing toward a result it already saw or treating training effort as proof of value.

  1. 01

    Specify task and release evidence

    Define the exact input, output, decision, users, context, consequences, baseline, metrics, segments, uncertainty behavior, acceptance thresholds, human role, and stop conditions.

  2. 02

    Audit and partition data

    Confirm rights and provenance, profile quality and representation, resolve label meaning, detect duplication and leakage, create versioned development and protected holdout sets, and record exclusions.

  3. 03

    Build the baseline ladder

    Measure the current method, rules, heuristics, existing models, and lower-complexity approaches under the same evaluation contract before adapting or training a candidate.

  4. 04

    Develop and challenge candidates

    Run controlled experiments, track code, configuration, data, artifacts, and cost, examine segment and error behavior, test attacks and misuse relevant to the context, and reject unjustified complexity.

  5. 05

    Evaluate blind and package release

    Run the locked holdout evaluation, document uncertainty and limitations, obtain accountable approval, reproduce the chosen artifact, define its system contract, and hand off monitoring, rollback, update, and retirement controls.

Model choice

Use the smallest learning change that clears the evidence bar.

The choice is not simply build or buy. Several lower-complexity options may solve the task with stronger control, lower operating burden, and easier verification.

01The correct behavior can be specified

Rules or ordinary software

Use deterministic logic when requirements are stable, exact, auditable, and testable. A model adds uncertainty without adding useful coverage in these cases.

Evidence: Rule owner, source facts, edge cases, test suite, error path, change frequency, maintenance cost, and baseline outcome.

02Capability exists but context is missing

Existing model with context

Use a supported model with prompting, structured constraints, tools, or retrieval when the base capability is adequate and organization-specific context can stay outside its weights.

Evidence: Provider and version, evaluation set, prompt and retrieval configuration, data boundary, limitations, cost, latency, update behavior, and exit path.

03Repeated behavior needs targeted change

Adapt or fine-tune

Adapt an existing model when representative examples can improve a stable task that prompting or retrieval does not satisfy, and the gain justifies new data and lifecycle ownership.

Evidence: Training rights, clean splits, baseline comparison, ablations, segment results, overfitting checks, artifact lineage, serving plan, and update triggers.

04The task and data justify ownership

Train a task-specific model

Train a new model when the representation, objective, constraints, or deployment boundary cannot be met responsibly by lower-complexity options and sufficient lawful data and expertise exist.

Evidence: Formal objective, data scale and coverage, architecture rationale, compute and security plan, reproducibility, independent evaluation, operating owner, and retirement plan.

Development controls

The model is only as trustworthy as its lineage and comparison.

Model work can look rigorous while leaking evaluation cases, obscuring data rights, averaging away harmful failures, or losing the exact artifact that produced a result. The controls protect the evidence chain.

Data lineage is reviewable
Record sources, permissions, collection and labeling processes, versions, transformations, exclusions, access, retention, deletion, and connections between raw records, prepared datasets, experiments, and artifacts.
Evaluation remains independent
Protect holdout cases from development, deduplicate related records across splits, prevent target and future information leakage, freeze measures before tuning, and preserve a separate final comparison.
Failure is examined by context
Report segment, rare-case, uncertainty, stress, adversarial, misuse, and out-of-scope behavior alongside aggregates. Connect each failure to consequence, mitigation, human handling, and residual risk.
Artifacts are reproducible and replaceable
Version code, configuration, environments, datasets, providers, weights, prompts, thresholds, and evaluation. Keep approval, deployment, monitoring, rollback, retraining, replacement, and retirement paths explicit.

Engagement fit

Use model development when evidence points beyond configuration and integration.

Good reason to begin

  • A precise prediction, ranking, classification, extraction, generation, language, or vision task has a meaningful baseline and measurable consequence.
  • Representative lawful data, domain expertise, evaluation owners, affected-user perspective, and operating capacity are available.
  • Existing services, prompting, retrieval, and deterministic approaches can be compared honestly under one evaluation contract.
  • The chosen model can be integrated, monitored, challenged, updated, rolled back, replaced, and retired within the product system.

Resolve before beginning

  • The problem is undefined, the desired output has no accountable use, or model training is being treated as the objective rather than a possible mechanism.
  • Data rights, provenance, label meaning, representation, sensitivity, retention, or the separation of development and evaluation cases remain unresolved.
  • The organization wants an aggregate benchmark score without accepting segment analysis, human-review burden, downstream consequences, or limits on use.
  • A simpler rule, process correction, retrieval path, existing service, or system integration has not yet been tested against the same outcome.
