LLM / TEXT / AUDIO
LLM, Text
& Audio
High-quality ground truth for LLM, text & audio.
RLHF, evaluation and SFT, fully outsourced.
From preference data (RLHF/DPO) to multi-step evaluation, instruction-response pairs (SFT), text classification and audio transcription. Native-speaker annotators plus an LLM-drafting × 100% human-inspection workflow deliver speed, low cost and high quality together.
Annotation types
we handle
From preference data to multi-step evaluation, instruction-response and audio — we recommend the best type for your use case.
Preference data (RLHF / DPO)
Comparing multiple responses and labeling the better one. We support everything from ranking to rationale comments, starting with evaluation design.
Multi-step evaluation & scoring
Scoring across multiple axes such as helpfulness, accuracy and safety — with consistent criteria, starting from evaluation-rubric design.
Instruction-response pairs (SFT)
Supervised fine-tuning data — model answers to instructions. We handle high-quality response generation that requires domain knowledge.
Text classification, NER & audio
Text classification, named-entity recognition (NER), and audio transcription, speaker diarization and emotion labels — a wide range of NLP and audio tasks.

Why ANOSUPO
Chosen not on price alone, but on the quality of judgment and hands-on partnership.
99.7% quality via
full inspection
We inspect 100% of deliverables, not samples — curbing drift in rubrics and preference criteria — and fix our own defects free of charge after delivery, proving quality with numbers.
Hands-on from
requirements up
No finalized spec needed. We proactively propose from evaluation axes and guideline design, with native speakers unifying the criteria, delivering clean results even hands-off.
$0 setup,
fully usage-based
No registration, management or monthly fees. Multi-step evaluation from $0.121/evaluation — pay only for what you create, with no minimum-order lock-in.
Enterprise security &
flexible delivery
ISO/IEC 27001 certified, NDAs with all staff. We support formats such as JSONL, specified tools and VPN connection.
Where LLM, text & audio annotation is used
The more it shapes your generative-AI quality,
the more evaluation-criteria design and full inspection pay off.
Generative AI & chatbots
Preference learning of responses via RLHF/DPO and tuning via multi-step evaluation — building evaluation data that raises safety and helpfulness.
Search & RAG
Assessing the validity of answer grounding and labeling search-result relevance — building evaluation data and gold sets that measure RAG accuracy.
Customer support
Classifying inquiries and extracting intent, plus drafting and editing responses — including domain-specific instruction-response (SFT) data.
Voice assistants & minutes
Audio transcription, speaker diarization, and emotion/intent labels — efficient training and evaluation data for speech recognition and meeting summarization.
