Choose an ML data labeling partner
your team can trust at scale

Abaka delivers high-accuracy labeling, RLHF, and multimodal QA through Abaka Forge—so you can iterate faster, reduce rework, and protect IP with compliant pipelines.

When labeling quality slips, everything downstream gets more expensive: evaluation metrics look “good” while real-world performance drifts, and each retrain cycle adds weeks of avoidable delay. Teams often lose 20–40% of labeling spend to rework—fixing inconsistent guidelines, duplicate edge cases, and weak reviewer coverage. Meanwhile, a backlog forms because each annotator can only ship so much per day, and internal SMEs get pulled into manual QA instead of model iteration. The result is slower releases, lower user trust, and compounding technical debt in your dataset.

Abaka acts as the ML data labeling partner that stabilizes your pipeline end-to-end—guideline design, gold sets, multi-layer QA, and secure delivery—so your training data keeps pace with experimentation. You get access to 1M+ vertically specialized annotators across 50+ countries, with scholar-network expertise spanning coding, math, medicine, and languages. Using Abaka Forge, we combine human intelligence with large-model automation to accelerate throughput while preserving auditability. Your data remains exclusively yours—never repurposed, resold, or shared.

The ML Data Labeling Partner Bottleneck

01

Quality Decay

Labeling errors rarely show up as obvious mistakes—they surface as subtle distribution shifts: inconsistent taxonomy use, boundary drift, or low-signal “agreeable” RLHF ratings. Even a 1–2% systematic bias in labels can overturn model rankings and force weeks of debugging. Abaka prevents quality decay with calibrated reviewers, inter-annotator agreement checks, gold-task gating, and escalation paths to domain SMEs. We operationalize 99% accuracy targets through multi-layer QA so your datasets stay stable across versions and vendors.

02

Volume Walls

Internal teams hit throughput ceilings fast. A single annotator’s max throughput is about 500 files/day, so scaling from 50K to 5M items becomes a staffing and management problem—not an ML problem. Abaka removes volume walls by coordinating large, specialized workforces and shifting routine steps into Abaka Forge automation, with clear batch-level acceptance criteria. You can ramp up for a deadline, then ramp down without layoffs or tooling churn—while keeping consistent labeling policy and reviewer coverage.

03

Compliance Friction

Data programs slow down when security reviews, NDAs, and access controls aren’t built into the labeling workflow. Teams lose weeks re-architecting pipelines after procurement flags risk—especially with PII, regulated data, or proprietary product telemetry. Abaka operates with SOC 2, ISO 27001, GDPR, and CCPA alignment, plus segregated secure pipelines and full IP provenance (0% copyright risk on collected data). That reduces back-and-forth and helps you move from pilot to production without redoing compliance.

01

Taxonomy design, guidelines, and gold standards

We translate your model goals into unambiguous labeling guidelines: class definitions, edge-case handling, and reviewer checklists. Abaka builds gold sets and calibration tasks to keep decisions consistent across teams and time. This is critical for intent classification, safety categories, medical entity labeling, and autonomous driving semantics. Deliverables include versioned specs, adjudication logs, and acceptance thresholds that your team can audit and iterate without resetting the workforce.

02

Image labeling for detection, segmentation, and attributes

Abaka supports bounding boxes, polygons, instance/semantic segmentation, keypoints, and dense captioning for retail, healthcare imaging workflows, and automotive perception. We pair specialist annotators with multi-layer QA and tooling inside Abaka Forge to keep tight consistency on occlusions, truncation rules, and attribute schemas. Output formats include COCO-style JSON, YOLO TXT, and mask exports. For image editing tasks, we can execute production-grade workflows priced at $8/hr.

03

Video annotation for tracking and temporal events

For driving, robotics, and surveillance-style data, we annotate temporal events, object tracks, action segments, and scene changes. Abaka’s pipeline uses frame sampling strategies, review checkpoints, and consensus adjudication to avoid drift across long clips. Teams can request spatial reasoning tags and instruction-following cues for multimodal training. Deliverables can include per-frame labels, timecoded segments, and dataset manifests, designed to plug into common training pipelines.

04

LLM RLHF, preference ranking, and rubric scoring

We run RLHF programs with clearly defined rubrics: helpfulness, harmlessness, factuality, and instruction adherence—plus domain-specific scoring for coding, math, law, or medicine. Abaka can source specialist graders from scholar-network domains and enforce consistency through calibration and audit trails. We support pairwise ranking, Likert scoring, and structured critiques that help your team train reward models and iterate prompts. Typical delivery includes rater guidelines, sampled audits, and disagreement analytics.

05

Math and coding data with expert reviewers

When your evaluation depends on correctness—not style—generalist labeling fails. Abaka provides math/coding capable annotators and reviewers, including Lean4 coverage, to generate and verify high-signal training data. We can execute LLM Math/Coding work at $18/hr with multi-layer QA and clear pass/fail criteria. Outputs can include verified solutions, step-checked rationales when requested, and error taxonomies your team can use to target model weaknesses.

06

3D/4D point cloud labeling for perception stacks

Abaka handles 3D cuboids, point-level segmentation, and track continuity for autonomous systems and embodied robotics. We apply consistent coordinate conventions, sensor metadata checks, and scene-level QA to reduce downstream alignment issues. Workflows cover indoor robotics mapping, outdoor driving scenes, and industrial inspection. Deliverables include JSON label files, point mask exports, and dataset-level statistics for coverage and class balance.

07

LiDAR + camera fusion annotation and alignment QA

For sensor fusion, the hard part is consistency: calibrations, timestamp alignment, and cross-modal label coherence. Abaka supports multi-sensor workflows that link 2D and 3D annotations while validating projection quality and occlusion logic. This helps perception teams reduce false positives in crowded scenes and improve long-tail robustness. We deliver aligned labels plus QA reports so your engineers can trace issues to calibration, labeling policy, or model behavior.

08

Abaka Forge workflows with auditability and speed

Abaka Forge is our all-in-one environment for collection, cleaning, annotation, training handoff, and production delivery across text, image, video, 3D/4D point cloud, and RLHF. Large-model automation can accelerate repetitive steps up to 50x while keeping human review in the loop. You can run secure, segregated pipelines under strict NDAs and export in practical formats your stack already supports. Platform credits are priced at $0.20 USD each.

Why Outsource ML Data Labeling Partner Work

01

Faster Delivery

You avoid the multi-week ramp of hiring, training, and QA management. Abaka can staff quickly across time zones and start with a Day 0–3 pilot so you see quality early. With Abaka Forge automation, repetitive steps are accelerated while humans focus on edge cases and adjudication. The result is fewer blocked training runs and more frequent iterations.

02

Direct Savings

Outsourcing reduces rework and the hidden cost of pulling engineers and SMEs into labeling operations. Abaka’s calibrated QA and acceptance criteria minimize relabel cycles that can waste 20–40% of spend. You also avoid tooling fragmentation by consolidating workflows in Abaka Forge—collection to delivery—so operations remain predictable as volume grows.

03

Risk Reduction

Security and provenance become part of the workflow, not an afterthought. Abaka operates under SOC 2 and ISO 27001 aligned controls, GDPR/CCPA readiness, strict NDAs, and segregated secure pipelines. We provide full IP provenance and do not repurpose or resell your data. That lowers vendor risk and procurement friction.

04

Elastic Scalability

Demand spikes are normal: new model versions, new geographies, new sensor configs. Abaka scales labeling capacity without breaking guideline consistency or reviewer coverage. Since an annotator’s throughput caps around 500 files/day, elastic staffing is essential for large backlogs. You can ramp up quickly, then scale down without reorganizing internal teams.

05

Domain Expertise

Generalist labeling is rarely sufficient for frontier ML. Abaka brings specialized annotators and reviewers across automobile, coding, languages, mathematics, medicine, science, business, and law. That lets you run high-signal programs—like verified math/coding tasks or medically grounded entity labeling—without overloading your internal experts.

06

Innovation Velocity

When labeling is stable, your team can spend time on modeling, evaluation, and product integration rather than ops firefighting. Abaka helps you version datasets, track guideline changes, and run targeted error analyses so each iteration produces learnings—not churn. With Abaka Forge, you can also introduce automation safely while keeping audit trails and human oversight.

How It Works

1) Day 0–3 — Scope, sample labeling, and acceptance criteria

We start with a short discovery to lock taxonomy, edge cases, and what “done” means (accuracy targets, reviewer depth, and output formats). Abaka labels a representative sample in Abaka Forge and returns early QA findings, ambiguity logs, and guideline improvements. You get a concrete delivery plan and a predictable quality gate before scaling.

2) Week 1–2 — Workforce ramp and multi-layer QA setup

Abaka staffs the right mix of generalists and domain specialists, then runs calibration with gold tasks and reviewer training. We implement multi-layer QA—spot checks, consensus, adjudication, and error taxonomy—so issues are caught early. Your team sees weekly reports on disagreement drivers, throughput, and guideline updates.

3) Week 2–3 — Production batches and stable exports

We move into steady-state production with batch-level acceptance testing and consistent exports aligned to your pipeline. Abaka Forge manages task routing, audit trails, and versioning so each dataset drop is traceable. Where appropriate, we apply large-model automation to accelerate repetitive work while preserving human review on edge cases.

4) Ongoing — Continuous improvement and dataset versioning

As your model changes, your labeling policy must evolve without breaking comparability. We manage controlled guideline revisions, run targeted relabeling only where needed, and maintain clear dataset versions. Abaka can expand scope to new geographies, languages, or sensors while preserving QA consistency and security controls.

5) Weekly — Reporting, audits, and change control

Every week you receive operational and quality reporting: throughput, error categories, reviewer findings, and edge-case escalations. We run audit sampling and can set up golden sets for regression checking so you know if quality shifts. Change requests are tracked with versioned specs, ensuring your team can reproduce results and trust dataset lineage.

Modality & Format Coverage

Your labeling partner should cover every format your roadmap touches—from RLHF rubrics to 3D perception. Abaka delivers consistent guidelines, QA, and exports across modalities, managed in Abaka Forge with auditable workflows.

Success Story

A leading enterprise GenAI team

The team’s assistant performed well in offline checks but produced inconsistent responses in production, especially on long-tail intents and domain-specific prompts. Their internal labeling effort couldn’t keep up with new product releases, and quality varied across batches as guidelines evolved. Each relabel cycle delayed training runs and created uncertainty about whether improvements came from model changes or dataset noise. They needed an ML data labeling partner that could stabilize RLHF and text labeling with auditable QA, while staying strict on data ownership and security requirements.

Abaka rebuilt the labeling specification into versioned rubrics and edge-case decision trees, then launched a calibrated RLHF pipeline: preference ranking plus structured critique fields tied to the customer’s evaluation dimensions. We staffed specialist reviewers from scholar-network domains for higher-signal judgments on technical prompts, and implemented multi-layer QA with gold tasks, adjudication, and weekly disagreement analytics. Using Abaka Forge, we managed secure workflows, audit trails, and clean exports (JSONL + reporting) so the customer could reproduce dataset versions and correlate dataset changes to model outcomes.

Within 3 weeks, the customer moved from inconsistent batches to stable, repeatable RLHF drops with clear acceptance thresholds and traceable guideline versions. Reviewer disagreement dropped as rubrics matured, and rework volume fell materially, enabling more frequent training iterations. The team used targeted error taxonomies to focus new data on failure clusters instead of relabeling everything. Outcome: 99% accuracy targets achieved on audited samples, a 2–3 week delivery cadence for new batches, and a measurable reduction in relabel-driven delays across releases.

What Customers Say

We needed a labeling partner that could operate like an extension of our ML org—clear specs, measurable QA, and predictable deliveries. Abaka helped us turn ambiguous edge cases into a stable rubric, and their weekly reporting made it easy to see what changed and why. Most importantly, dataset drops became reproducible, which improved our confidence in experiment results.

Director of Applied MLEnterprise AI Software Company

Our internal team kept getting dragged into annotation triage. Abaka’s multi-layer QA and adjudication workflow reduced rework and freed our SMEs to focus on modeling. The ability to scale up quickly without losing consistency was the difference between monthly and weekly iteration cycles for us.

Head of Data OperationsAutonomous Systems Company

Security and provenance were non-negotiable for our org. Abaka’s secure pipelines and audit trails made procurement straightforward, and we didn’t have to redesign our process midstream. Their team was disciplined about change control, so guideline updates didn’t break comparability across dataset versions.

Security & Compliance LeadRegulated Technology Company

We tried generalist labeling vendors and the signal just wasn’t there for technical prompts. Abaka’s specialist reviewers improved the quality of our preference data and the clarity of critiques. That made our reward-model iteration more efficient because we could target specific failure modes instead of guessing.

Frequently Asked Questions

How much does an ML data labeling partner cost?
Pricing depends on modality, complexity, and QA depth, but we use real, transparent rate cards and measurable acceptance criteria. Examples: LLM Math/Coding labeling can be $18/hr, STEM generalist work can be $12/hr, dense captioning can be $6/hr, and road lane annotation can be $3/km. If you use Abaka Forge credits for workflow automation and platform usage, credits are $0.20 USD each. We’ll propose a blended plan after a small Day 0–3 sample so you can validate quality before scaling.
How fast can you deliver labeled data after kickoff?
Most teams see a meaningful first delivery within 2–3 weeks, depending on dataset readiness and scope. We typically run a Day 0–3 sample to finalize guidelines and acceptance thresholds, then ramp production in Week 1–2 with calibrated reviewers and gold tasks. For urgent timelines, we can prioritize staffing and batch size while keeping QA gates intact. You’ll get a weekly delivery cadence once the workflow stabilizes.
What modalities and output formats do you support for labeling?
We support text, LLM RLHF, image, video, 3D/4D point cloud, LiDAR + camera fusion, and audio workflows. Output formats are tailored to your pipeline and commonly include JSONL/CSV for NLP and RLHF, COCO-style JSON/YOLO TXT/PNG masks for images, timecoded JSON for video, and JSON plus sensor-linked manifests for 3D and fusion datasets. If you have a custom schema, we can map exports to your spec and include validation checks in the delivery step.
How do you ensure labeling accuracy and consistency?
Accuracy comes from process, not hope. Abaka uses versioned guidelines, gold-task gating, reviewer calibration, and multi-layer QA that includes spot checks, consensus, and adjudication for disagreements. We track inter-annotator agreement and produce error taxonomies so you can see where ambiguity or policy gaps cause variance. For domain-sensitive tasks (math, coding, medicine, law), we route work to specialists and add dedicated review layers to maintain consistent decisions across batches.
Can you meet security and compliance requirements for sensitive data?
Yes. Abaka operates with SOC 2 and ISO 27001 aligned controls and supports GDPR and CCPA requirements. We use strict NDAs, segregated secure pipelines, and controlled access patterns for sensitive workflows. We also provide full IP provenance, including 0% copyright risk on collected data, and we do not repurpose or resell your data. If your org needs additional security steps (e.g., dedicated environments or stricter access segmentation), we can scope that during onboarding.
Do you support multilingual data labeling and global coverage?
Yes. Abaka supports multilingual labeling across 50+ countries, which helps when you need locale-specific intents, culturally appropriate RLHF judgments, or regionally grounded entity labeling. We can run language-specific guidelines, separate calibration per language, and consistent reviewer policies so output quality doesn’t vary by geography. Deliverables can include language tags, locale metadata, and stratified QA reporting so your team can track performance and coverage per market.
How is Abaka different from other data labeling companies?
Abaka is optimized for frontier-quality and trust. We pair large, specialized workforces with scholar-network domain expertise and multi-layer QA designed for correctness and consistency—not just raw volume. Our compliance posture includes SOC 2 and ISO 27001 aligned controls, and we provide full IP provenance. We also never build models that compete with you, and your data is exclusively yours—never repurposed, resold, or shared. Abaka Forge adds end-to-end workflow control with auditability.
How do you handle scope changes or labeling guideline updates mid-project?
We treat changes as versioned releases. Abaka logs guideline updates, clarifies impact (what needs relabeling and what doesn’t), and runs targeted backfills rather than broad relabeling when possible. We maintain dataset and guideline versions so your team can reproduce experiments and compare model results cleanly. Weekly change control checkpoints keep policy drift from creeping in, and we can create gold sets that act as regression tests when guidelines evolve.
Can we start with a small pilot before committing to a full program?
Yes—starting with a pilot is the recommended path. In Day 0–3, we label a representative sample, surface ambiguity, propose guideline improvements, and agree on acceptance thresholds. In Week 1–2, we ramp the workforce and QA layers and deliver a first production batch to validate stability. A pilot lets you evaluate quality, throughput, and reporting before scaling, and it reduces the risk of spending heavily on a spec that needs revision.
Who owns the labeled data and can it be reused elsewhere?
You own your data and the resulting labeled outputs. Abaka does not repurpose, resell, or share your datasets—your data is exclusively yours. We also never build models that compete with you, which removes incentives to treat customer data as a long-term asset for internal training. If your team requires specific IP clauses, retention policies, or deletion timelines, we can incorporate those into the project agreement and operational workflow.
What tools do you use for data labeling and QA management?
We use Abaka Forge to run collection, cleaning, annotation, QA, and delivery with audit trails and secure workflows. It supports text, RLHF, image, video, and 3D/4D point cloud labeling, and it can incorporate large-model automation to speed up repetitive steps while keeping human review in the loop. We provide export validation and reporting so your team receives consistent, production-ready outputs aligned to your schema.
Is there a minimum dataset size or minimum contract length?
We support both small and large engagements. Minimums depend on modality and the level of specialization required, but many teams start with a small pilot sample to validate guidelines and QA before scaling. If you only need a narrow dataset (e.g., a targeted evaluation set or a small RLHF batch), we can scope a lean plan with clear acceptance criteria. If you need sustained throughput, we’ll propose a weekly cadence that balances staffing, cost, and QA depth.
