      <abstract>
        <p>Nowadays, we need AI systems capable of engaging and working with people, perceiving and acting within changing contexts, being aware of their limits and adapting to new scenarios, behaving correctly in complex social settings, being aware of their security and trust perimeters, and of being aware of the environmental and societal efect that their implementation and execution may imply. In summary, we require a formerly undiscovered AI. Symbiotic-AI systems should disclose human cognitive capabilities to improve the efectiveness of information access and decision-making. This is achieved by combining methods for determining who is interacting with the system and how. The former includes the definition of strategies for acquiring and exploiting users' personal information gathered by combining diferent strategies and heterogeneous sources. In contrast, the latter includes detecting and interpreting human signals acquired from various sources, such as advanced machine learning (particularly deep learning) and natural language processing.</p>

          </p>
          <p>This research task involves creating, organizing, and
maintaining large volumes of data or corpora that are
used to train and test large language models. The process
of data curation and ingestion is a complex and
timeconsuming task, but it is necessary to ensure the
quality of the model’s output and to support explainability,
transparency, and interoperability [3, 4, 5]. Additionally,
data security and privacy need to be taken into account,
such as gaining participants’ consent, anonymizing or
de-identifying data, and ensuring that it is securely kept
and managed. Data curation and intake are critical
components of developing Large Language Models (LLMs)
that can efectively understand and respond to human
language [6]. This is especially crucial to allow for
diversity in terms of the languages and topics covered [7].</p>
          <p>Recognizing possible biases in the data curation and
ingestion processes and taking proactive steps to remove
them is critical. Data security, ethics, and privacy must
be considered, especially when working with sensitive
data. It is critical that we protect people’s privacy rights
and prevent data exploitation [8].</p>

          <title>2.2. Combination of exogenous and endogenous semantics</title>
          <p>
            This research task involves a combination of exogenous
and endogenous semantics, utilizing multimodal
embeddings and generative tasks through attentive,
selfsupervised training and large-scale-based transfer
learning [9]. Exogenous semantics refers to external
information that is used to train the model, while endogenous
semantics refers to internal information that is
subsequently learned by the model from the training data.
Multidimensional embeddings involve representing words
and sentences using multiple modalities, allowing the
model to capture diferent facets of language, leading to
improved performance [
            <xref ref-type="bibr" rid="ref26">10</xref>
            ]. Linguistic knowledge can be
added into embeddings to increase the representations’
quality [

          <title>Models</title>
          <p>The study of strategies for training, fine-tuning, and
motivating Large Language Models is part of this research
task. It is critical to train adaptive LLMs, which can learn
and alter their knowledge depending on new data and
feedback [19, 6]. This must be done while keeping
multimodality in mind. The task goal is to solve this issue
and examine options that may be available for less
frequently spoken languages. Fine-tuning and prompting
are two approaches often employed in Big Language
Understanding, a subset of Natural Language Processing.
These strategies are used to boost the performance of
pre-trained language models like GPT-3 for specific tasks
or domains. Fine-tuning entails picking a smaller dataset
relevant to the job and then training the model on it.
Except for the last layer, the weights of the pre-trained
model usually are frozen. Fine-tuning can help with
various NLP tasks, including sentiment analysis, question
answering, and text categorization. Prompting, on the
other hand, is sending a specific prompt or input to a
pre-trained language model in order for it to respond.
The prompt might be a single brief word or sentence that
ofers context for the model to respond to. The purpose
of prompting is to increase the model’s relevance and
accuracy. Task-specific prompts can be created for writing
a news story summary or answering a specific question.</p>

          <p>The FAIR approach is comprehensive and
multidisciplinary, with the goal of profoundly rethinking the
foundations of AI while also studying the societal
consequences of emerging kinds of AI. Depending on the path
that the AI revolution takes, AI will either empower or
reduce human agency; expand or replace the human
experience; create new forms of human activity or reduce
jobs; help distribute well-being for many or increase the
concentration of power and wealth in the hands of a few;
expand or endanger democracy in our societies; help fight
climate change or increase emissions. FAIR researchers
want AI to be part of the solution, not the issue, to the
world’s social, financial, ethical, and environmental
concerns. The merging of human intelligence with artificial
intelligence (AI) to improve both capabilities is thought
of as Symbiotic-AI. This form of collaboration has the
potential to forge strong alliances by allowing people to
profit from AI’s speed, eficiency, and processing capacity
while giving machines human-like judgment, reasoning,
and creativity.</p>
