Scale production-ready datasets with
ML Data Labeling Services

Abaka delivers scholar-grade labeling and multi-layer QA across text, image, video, and 3D—so your team ships higher-accuracy models without slowing down roadmap velocity.

When labeling is inconsistent, your model learns the wrong rules—then fails in the real world. Teams often lose 2–6 weeks per iteration chasing silent label noise: unclear guidelines, drifting annotators, and untracked edge cases. The cost shows up as lower offline metrics, higher production escalations, and wasted GPU cycles retraining on flawed ground truth. Even a 1–2% accuracy drop can block launches, trigger manual-review staffing, and force expensive re-collection when you realize the dataset can’t support the next milestone.

Abaka turns labeling into an engineered pipeline: scoped taxonomies, calibrated annotators, and multi-pass QA with measurable acceptance criteria. You get vertically specialized annotators across 50+ countries, throughput controls (up to 500 files/day per annotator), and governance aligned to SOC 2, ISO 27001, GDPR, and CCPA. Using Abaka Forge, we standardize instructions, audit disagreements, and deliver clean outputs your ML stack can ingest immediately—so you can iterate faster, reduce rework, and keep ownership of every asset.

The ML Data Labeling Services Bottleneck

01

Quality Decay

Label quality usually erodes as projects scale: new annotators interpret rules differently, edge cases multiply, and “good enough” judgments slip into gold data. A small amount of noise compounds—1–3% drift across classes can flip model ranking decisions and send you into weeks of re-annotation. Abaka prevents quality decay with rubric-driven guidelines, calibration tasks, and multi-layer QA. We cap throughput at 500 files/day per annotator to reduce fatigue and use targeted rework queues so fixes are fast and traceable.

02

Volume Walls

Roadmaps don’t wait for labeling. Product teams may need tens of thousands of images, hours of audio, or multi-turn conversations labeled on tight timelines, but internal teams hit hiring and tooling ceilings quickly. Without elastic capacity, delivery slips by 2–4 weeks and model training stalls. Abaka provides 1M+ specialized annotators across 50+ countries, elastic staffing, and platform workflows in Abaka Forge. You can ramp up for a launch, then scale down—without breaking consistency or losing institutional knowledge.

03

Compliance Friction

Data labeling often touches sensitive content—customer chats, medical notes, financial documents, or safety-critical perception logs. Compliance reviews, access controls, and audit trails can slow projects to a crawl, adding 1–3 weeks before production starts. Abaka is built for secure delivery: SOC 2 and ISO 27001-aligned operations, GDPR/CCPA practices, strict NDAs, segregated pipelines, and full IP provenance with 0% copyright risk on collected data. Your data stays exclusively yours—never repurposed or resold.

01

Task taxonomy design and labeling playbooks

We translate your ML objective into a labeling spec that scales: class definitions, edge-case rules, and disagreement handling. Abaka Forge hosts living guidelines, in-tool examples, and reviewer notes so decisions stay consistent across regions. This is especially effective for automotive perception (lanes, drivable space), retail catalog normalization, and financial document extraction. Deliverables include label schemas, acceptance thresholds, and a change-log so your team can reproduce training runs reliably.

02

Multi-layer QA with measurable acceptance criteria

Abaka runs multi-pass QA with calibrated reviewers and targeted rework queues. We use gold tasks, blind audits, and inter-annotator agreement checks to surface ambiguity early. For teams targeting 99% accuracy, we align on what “accuracy” means per task (IoU for masks, span overlap for NER, rubric scores for RLHF). Outputs include QA reports, confusion patterns, and prioritized guideline updates—so quality improves over time instead of drifting.

03

Computer vision labeling for production datasets

We label images for detection, segmentation, tracking, and dense captioning—supporting use cases like shelf analytics, defect detection, and robotics perception. Abaka Forge enables polygon, polyline, and keypoint tooling with reviewer overlays and dispute resolution. We also support image editing workflows when you need curated training inputs (e.g., removing artifacts or standardizing crops). Deliver in COCO/YOLO/VOC-style JSON, plus audit metadata for traceability.

04

Video spatial reasoning and temporal annotation

For video, we handle frame-by-frame tracking, action tagging, and event timelines for autonomy, security monitoring, and sports/media understanding. We design sampling strategies to reduce cost while maintaining coverage (keyframes, segments, and hard-negative mining). Abaka Forge manages reviewer checkpoints and temporal consistency checks so IDs don’t drift across frames. Outputs can be delivered as per-frame JSON, timeline CSV, or task-specific schemas your pipeline expects.

05

3D/4D point cloud labeling and QA

We label point clouds for 3D boxes, instance segmentation, and scene semantics—useful for autonomous systems, robotics navigation, and industrial digital twins. Abaka Forge supports 3D tooling workflows and reviewer overlays. We establish occlusion rules, class hierarchies, and spatial consistency checks so labels hold up in downstream tracking and planning. Deliverables include 3D annotation JSON, sequence alignment notes, and QA summaries that highlight hard scenes.

06

LLM RLHF: preference, rubric, and safety labels

We run RLHF pipelines: instruction following checks, pairwise preferences, multi-criteria rubrics, and safety tagging aligned to your policy. Abaka recruits domain specialists (coding, math, medicine, law, languages) and trains them on your guidelines. Abaka Forge manages prompt/response versioning and reviewer escalation so edge cases are resolved quickly. Outputs include preference datasets, scored rubrics, and structured feedback fields for training and evaluation.

07

Multilingual text annotation and normalization

For global products, we provide multilingual annotation: intent and sentiment labels, entity extraction, translation QA, and content moderation signals. With annotators across 50+ countries, we localize guidelines and create language-specific examples while preserving a unified schema. Abaka Forge captures annotator rationales and reviewer notes to improve consistency. Deliverables include JSONL/CSV with language tags, span offsets, and confidence fields for downstream training.

08

Secure operations, IP provenance, and reporting

Abaka is a trustworthy data partner for frontier AI—founded 2019, self-funded and profitable, with strict NDAs and segregated pipelines. We provide audit-friendly reporting: batch manifests, reviewer logs, and acceptance statistics. We never build models that compete with you; your data is exclusively yours—never repurposed, resold, or shared. When needed, we can combine collection, cleaning, annotation, and production workflows in Abaka Forge for end-to-end delivery.

How It Works

1) Day 0–3 — Scope, access, and label schema

We align on your model goals, target metrics, and acceptance criteria. Abaka builds a task taxonomy, edge-case rules, and sampling plan, then provisions a secure Abaka Forge workspace with role-based access, NDAs, and pipeline segregation as needed.

2) Week 1–2 — Pilot batch and calibration

We run a pilot to validate guidelines, measure disagreement, and tune QA gates. You review examples, approve rubric changes, and lock the schema. We then train annotators and reviewers, establish gold tasks, and finalize delivery formats (JSONL/COCO/CSV).

3) Week 2–3 — Production ramp and QA stabilization

We scale throughput while keeping consistency through multi-layer QA, targeted rework, and weekly reports. Abaka Forge centralizes guideline updates and exception handling so every change is tracked. You receive validated batches on an agreed cadence.

4) Ongoing — Edge-case mining and continuous improvement

As your model evolves, we mine failures and hard negatives, expand the taxonomy responsibly, and keep labels consistent across versions. We maintain audit logs, reviewer notes, and batch manifests so you can reproduce training and diagnose shifts.

5) Weekly — Metrics review, change requests, and roadmap sync

Each week we review QA metrics, turnaround time, and error patterns with your team. We apply change requests via controlled guideline revisions, then re-calibrate annotators to prevent drift. The goal: stable quality, predictable delivery, and faster iteration.

Modality & Format Coverage

Your roadmap spans modalities—so your labeling partner should too. Abaka supports end-to-end annotation with consistent governance, measurable QA, and outputs tailored to your training and evaluation pipelines.

Success Story

A leading GenAI / Foundation Models AI team

The team needed reliable ML data labeling services for a fast-moving training loop: instruction-following prompts, preference labels, and safety tags across multiple domains. Internal labeling couldn’t keep pace with new guidelines and edge cases, and reviewer time was being consumed by dispute resolution rather than model iteration. They also required a security posture aligned to enterprise expectations, with strict access controls and clear ownership of all labeled data and outputs.

Abaka designed a rubric-driven RLHF program with clear acceptance criteria, calibrated annotators, and domain reviewers for coding and math tasks. We operationalized guideline updates inside Abaka Forge, introduced gold tasks and blind audits, and created an escalation path for hard policy questions. The workflow split production labeling from specialist review, allowing fast throughput while preserving quality. Weekly reporting tracked disagreement hotspots and fed concrete guideline revisions back into training—without interrupting batch delivery.

Within 3 weeks, the team stabilized labeling quality and increased delivery predictability while reducing reviewer load. They achieved 99% accuracy targets on agreed QA checks, shortened iteration cycles by 2 weeks, and expanded coverage into additional domains without re-platforming. Output datasets arrived in consistent JSONL formats with full audit metadata, enabling repeatable training runs and faster debugging of model regressions—resulting in measurable improvement in offline eval performance and fewer production escalations.

Frequently Asked Questions

How much do ML data labeling services cost?
Pricing depends on modality, complexity, and the QA bar you need, but we anchor costs to real, auditable units. For example, LLM math/coding labeling can be priced at $18/hr, STEM generalist work at $12/hr, dense captioning at $6/hr, and image editing at $8/hr. For automotive perception, road lane labeling is available at $3/km. We’ll propose a blended rate card after a Day 0–3 scope, and we can run a small pilot first to validate quality and throughput before scaling.
How fast can you start and deliver the first labeled batch?
Most teams can start within Day 0–3 for scoping, access, and schema alignment, then receive an initial pilot batch in Week 1–2. Production ramp typically begins in Week 2–3 once guidelines and QA gates are calibrated. Timeline varies by modality and how quickly label definitions are approved, but the goal is always the same: deliver early batches quickly so you can train, evaluate, and refine before committing to full-scale production.
What data types and output formats do you support?
We support text, LLM RLHF, images, video, 3D/4D point clouds, LiDAR + camera fusion, and audio. Output formats are tailored to your pipeline: JSONL/CSV for text and RLHF, COCO/YOLO/VOC-style outputs for vision, per-frame JSON and timeline CSV for video, and structured JSON plus manifests for 3D and fused sensor work. We also include batch manifests and audit metadata so datasets are traceable and reproducible over time.
How do you ensure labeling accuracy and consistency?
We treat accuracy as a system, not a promise. Abaka uses rubric-driven guidelines, calibration tasks, gold data, blind audits, and multi-layer QA with targeted rework queues. We cap throughput at 500 files/day per annotator to reduce fatigue-driven errors and maintain reviewer escalation for edge cases. For teams targeting 99% accuracy, we define what accuracy means per task and report it weekly, along with confusion patterns and guideline improvements.
Can you meet enterprise security requirements for sensitive datasets?
Yes. Abaka operates with SOC 2 and ISO 27001-aligned practices, GDPR and CCPA support, strict NDAs, segregated secure pipelines, and audit-friendly controls. We can enforce role-based access, least-privilege workflows, and structured reporting for governance. We also maintain full IP provenance and do not repurpose or resell your data. If you have additional internal controls, we’ll map them during Day 0–3 and incorporate them into the delivery plan.
Do you support multilingual labeling and localization?
Yes. We support multilingual text annotation, translation QA, sentiment/intent labels, and language-specific normalization with annotators across 50+ countries. We localize guidelines with language-specific examples while keeping a consistent global schema, which helps you train models that generalize across regions. Deliverables can include language tags, span offsets, and structured rationales so you can analyze disagreement patterns and improve prompts or model behavior per locale.
How are you different from other data labeling companies?
Abaka is positioned as a trustworthy data partner for frontier AI: founded in 2019, self-funded and profitable, with enterprise-grade compliance and strict NDAs. We never build models that compete with you—your data is exclusively yours and never repurposed, resold, or shared. Operationally, we combine domain-specialist annotators with a platform workflow (Abaka Forge) that keeps guidelines, QA, and audit trails tightly managed across modalities.
What if we need changes to the taxonomy or guidelines mid-project?
Change requests are expected—models evolve and edge cases appear. We manage updates through controlled guideline revisions in Abaka Forge, followed by re-calibration tasks and reviewer alignment to prevent drift. We can also reprocess impacted subsets through targeted rework queues rather than redoing everything. Every change is tracked with a versioned change-log and batch manifests, so you can reproduce training runs and understand which label policy produced which model outcome.
Can we run a pilot before committing to a large labeling engagement?
Yes. A pilot is the fastest way to validate label definitions, QA thresholds, and delivery formats before scaling. In Week 1–2, we deliver a representative batch with measurable QA, disagreement analysis, and a refined guideline set. You’ll see how edge cases are handled and how outputs integrate into your training pipeline. After the pilot, we provide a scale plan: staffing, weekly throughput targets, QA gates, and the cadence for delivery and reporting.
Who owns the labeled data and derived datasets?
You do. Abaka’s policy is that your data is exclusively yours—never repurposed, resold, or shared. We operate under strict NDAs and segregated pipelines, and we provide full IP provenance for delivered datasets. If you supply source data, we treat it as your IP; if we collect data on your behalf, we ensure 0% copyright risk on collected data and deliver provenance records alongside the dataset for auditability.
What tools do you use for labeling and QA?
We use Abaka Forge—our all-in-one platform for collection, cleaning, annotation, and production workflows across text, image, video, 3D/4D point cloud, and RLHF. Forge centralizes guidelines, reviewer workflows, escalation, and audit logs so quality stays consistent across large teams. If you need specific export schemas or integration steps, we adapt outputs to match your training stack while keeping internal governance consistent.
Is there a minimum project size for ML data labeling services?
There’s no single minimum, but the best fit is when you need repeatable quality and governance—not just a one-off batch. We commonly start with a pilot sized to validate your taxonomy and QA bar, then scale to production. If your project is small, we can still help by focusing on high-impact tasks: defining guidelines, labeling a gold dataset, or creating evaluation sets. We’ll recommend the smallest scope that still produces reliable, training-ready outputs.
