Cohere needed to evaluate Command A to see if it delivers the right outcomes in specialized, real-world scenarios. Invisible sourced PhD level experts across a range of specialisms, including STEM, Math, SQL, and subject matter experts in HR, retail and aviation, for blind annotation.
Cohere expanded into 10 languages with Invisible's expert annotators fine-tuning in rare programming languages to tackle specialized use cases resulting in transformative improvements in model performance.
“The deep partnership with Invisible stood out—they felt like part of our team and consistently went beyond what we asked for.”
Written for teams that already know how to ship text-only models and are now being asked to “make it multimodal”.
How to design outcomes, decompose systems, curate your data, and technical challenges to help you prepare to evaluate and launch your multimodal model.

Domain expertise ensures that training data accurately reflects the complexities, terminology, and nuances of a field, resulting in higher model precision and relevance. Experts help capture edge cases and subtleties that generic annotators might miss, especially in scientific, medical, and technical domains.
Expert annotations provide validated, context-aware labels that help models learn correct patterns and relationships, reducing errors caused by ambiguous or incomplete data, critical for decision-making in high-stakes areas.
Effective experts typically hold advanced degrees or extensive practical experience in their domain, possess clear communication skills, and demonstrate the ability to apply domain knowledge to training annotations and quality evaluations essential for research-grade datasets.
Agentic workflows break complex tasks into discrete, manageable steps, training AI agents to reason, plan, and act autonomously across sequences of decisions, improving model reliability and handling of multi-stage processes beyond single prompt responses.
Unlike traditional models trained on static input-output mappings, agentic training involves dynamic environments where models simulate interaction, decision-making, and adjustment, closer to real-world tasks requiring operational autonomy.
Techniques include reinforcement learning from human feedback, hierarchical task decomposition, tool use training, and curriculum learning that gradually exposes agents to increasing task complexity and dependencies.
Models must understand language nuances, idioms, and cultural context varying across regions to provide accurate and acceptable responses, avoiding mistranslations and improving user trust and engagement worldwide.
Scarcity of high-quality labeled data, limited expert availability, and dialectal variations complicate training, requiring innovative data augmentation, expert crowdsourcing, and localization frameworks.
Effective localization tailors language, tone, and content to local norms, regulatory constraints, and cultural preferences, making AI solutions more relevant and compliant in target markets.
It includes realistic simulations of business workflows, access to relevant structured and unstructured data, integration with operational tools, and support for complex, multi-agent interactions to mimic real-world conditions.
They expose agents to practical constraints, policy rules, exception handling, and interactive decision-making, improving model robustness and transferability to production environments.
Collaboration among agents or between humans and agents, through dialog and shared reasoning, enriches context understanding and supports sophisticated workflows requiring coordination and negotiation.
Multimodal inputs reflect real-world interactions more comprehensively than text alone, enabling models to understand tone, gestures, spatial relationships, and contextual cues critical for accurate interpretation and action.
Use of expert annotators for modality-specific labels, cross-modal alignment of annotations, high-fidelity data capture, and rigorous quality checks ensure annotations faithfully represent complex sensory inputs.
They provide spatial and temporal context necessary for tasks like object recognition, motion analysis, and environment mapping, enhancing model situational awareness and decision-making.
Red-teaming simulates adversarial scenarios and edge cases to expose vulnerabilities, while policy evaluations ensure alignment with regulatory and ethical standards, preventing harmful or biased outputs.
Techniques include rule-based filtering, human oversight in critical decisions, transparent model explainability, and continuous monitoring with feedback loops to detect and correct deviations.
Models drift over time due to new data distributions and evolving contexts; fine-tuning with ongoing evaluation helps preserve alignment, robustness, and compliance in dynamic environments.
