TLDR: When working with LLMs, the risks for the L&D workflow and its impact on substantive learning are real:Hallucination — LLMs invent plausible-sounding facts that aren’t trueDrift — LLM outputs wander from your brief without clear constraintsGeneric-ness — LLMs surface that which is most common, leading to homogenisation and standardisation of “mediocre”Mixed pedagogical quality — LLMs do not produce outputs which are guaranteed to follow evidence-based practiceMis-calibrated trust — LLMs invite us to read guesswork as dependable, factual knowledge These aren’t edge cases or occasional glitches—they’re inherent to how AI / all LLMs function. Prediction machines can’t verify truth. Pattern-matching can’t guarantee validity. Statistical likelihood doesn’t equal quality.

The analysis uncovered an average of 11 different types of data out of the 35 possible. As mentioned earlier, Google Gemini stands out as the most data-hungry service, collecting 22 of these data types, including highly sensitive data like precise location, user content, the device's contacts list, browsing history, and more.Among the analyzed applications, only Google Gemini, Copilot, and Perplexity were found to collect precise location data. The controversial DeepSeek chatbot stands right in the middle, collecting 11 unique types of data, such as user input like chat history.

The different types of agents Now that we have a general definition of AI Agents, let us look at some specific agent types and how they would be applied to a travel booking AI agent.

システム - エージェントを単一のコンポーネントとしてではなく、複数のコンポーネントから成るシステムとして考えることが重要です。AIエージェントの基本的な構成要素は以下の通りです： 環境 - AIエージェントが動作する定義された空間。例えば、旅行予約のAIエージェントの場合、環境はエージェントがタスクを完了するために使用する旅行予約システムとなります。 センサー - 環境には情報があり、フィードバックを提供します。AIエージェントはセンサーを使用して、環境の現在の状態に関する情報を収集・解釈します。旅行予約エージェントの例では、ホテルの空室状況や航空券の価格などの情報を旅行予約システムから取得します。 アクチュエーター - AIエージェントが環境の現在の状態を受け取った後、そのタスクに応じて環境を変化させるためにどのようなアクションを実行するかを決定します。旅行予約エージェントの場合、ユーザーのために空室を予約するアクションが該当します。

AIエージェントは、大規模言語モデル（LLM） に ツールや知識へのアクセス を提供し、その能力を拡張することで アクションを実行 できるようにする システム です。

Cursor noted Claude is once again best-in-class for real-world coding tasks, with significant improvements in areas ranging from handling complex codebases to advanced tool use. Cognition found it far better than any other model at planning code changes and handling full-stack updates. Vercel highlighted Claude’s exceptional precision for complex agent workflows, while Replit has successfully deployed Claude to build sophisticated web apps and dashboards from scratch, where other models stall. In Canva’s evaluations, Claude consistently produced production-ready code with superior design taste and drastically reduced errors.

In extended thinking mode, it self-reflects before answering, which improves its performance on math, physics, instruction-following, coding, and many other tasks.

If robust general-purpose reasoning abilities have emerged in LLMs, this bolsters the claim that such systems are an important step on the way to trustworthy general intelligence.

While large language models (LLMs) are not explicitly trained to reason, they have exhibited “emergent” behaviors that sometimes look like reasoning.

The word “reasoning” is an umbrella term that includes abilities for deduction, induction, abduction, analogy, common sense, and other “rational” or systematic methods for solving problems. Reasoning is often a process that involves composing multiple steps of inference.

LLMs are substantially better at solving problems that involve terms or concepts that appear more frequently in their training data, leading to the hypothesis that LLMs do not perform robust abstract reasoning to solve problems, but instead solve problems (at least in part) by identifying patterns in their training data that match, or are similar to, or are otherwise related to the text of the prompts they are given.

[Memorization and reasoning are] not a dichotomy, but rather they can co-exist in a continuum.

How to pick a LLM (Jan 2025): — Claude Sonnet is my daily driver. Fast, great writing and great code. — o1 / o1 pro for complex reasoning tasks (tough refactor) — Deepseek v3 for fast cheap API / 4-o replacement — Gemini for ultra long context, Flash and video understanding

Critics of A.I. use by religious leaders have pointed to the issue of hallucinations — times when chatbots make stuff up. While harmless in certain situations, faith-based A.I. tools that fabricate religious scripture present a serious problem. In Rabbi Bot’s sermon, for instance, the A.I. invented a quote from the Jewish philosopher Maimonides that would have passed as authentic to the casual listener.

Really good PMs and engineers will actually start to converge. With LLMs, coding won't be enough to differentiate as an engineer, you'll need to think about the product, business KPIs, strategy etc. You need to think about solutions to problems, not software tools. And PMs are going to be expected to get more technical.

Improved GPU utilization, better LLM storage solutions, and prompt caching features in deployment tools like KServe will continue to make it more accessible to deploy a variety of models.

People will use LLMs for simpler tasks, not more complex ones.

We’ll also see a big surge in the use of buzzword-heavy AI concepts like Retrieval-Augmented Generation (RAG) systems, generative AI, and cloud-based AI products, all of which will become easier to use and, hopefully, cheaper, thereby driving further broad adoption.

The concept of RAG is relatively straightforward. It involves two main components: a document retriever and a large language model (LLM). The document retriever is responsible for finding relevant information from a large corpus of documents based on the input question using semantic search. This information is then passed to the LLM, which generates a response. The unique aspect of RAG is the way it combines these two components. Instead of retrieving documents and then generating a response in two separate steps, RAG uses a joint process where the document retrieval and response generation steps are connected. This allows the model to consider multiple documents simultaneously when generating a response, leading to more accurate and contextually relevant outputs.

In fourth generation  warfare, seen here on the right, the direct control of the bots is  replaced with AI. Using AI we can define artificial personalities with artificial social media behaviour, that will make it increasingly difficult to detect the bots.

Data scientists, MLOps engineers, or AI developers, can mount large language model weights or machine learning model weights in a pod alongside a model-server, so that they can efficiently serve them without including them in the model-server container image. They can package these in an OCI object to take advantage of OCI distribution and ensure efficient model deployment. This allows them to separate the model specifications/content from the executables that process them.

why training artificial intelligence in research context is and should continue to be a fair use

three different issues that are being implicated by artificial intelligence. And this is true with, you know, all artificial intelligence, not just a generative but particularly generative.

So how does this work? I wanted to give this picture of what's actually happening behind the scenes, especially with this question and answer. So first, I will say that we're using a combination of OpenAI's GPT 3.5 to do this as well as some open source, smaller open source models to generate the vectors for the semantic search.

Our core assumption is that foundational models, having been extensively trained in English texts, possess a substantial level of understanding and reasoning capabilities. Transferring these capabilities from English to another language, such as Korean, could be more efficient than developing performance from standalone Korean pre-training.

The same LM can be a much more or less capable agent depending on the enhancements added. The researchers created and tested four different agents built on top of GPT-4 and Anthropic’s Claude:

The latest GPT-4 model from OpenAI, which is trained on human preferences using a technique called RLHFEstimated final training run compute cost: ~$50mModel version: gpt-4-0613

Additionally, students in the Codex group were more eager and excited to continue learning about programming, and felt much less stressed and discouraged during the training.

On code-authoring tasks, students in the Codex group had a significantly higher correctness score (80%) than the Baseline (44%), and overall finished the tasks significantly faster. However, on the code-modifying tasks, both groups performed similarly in terms of correctness, with the Codex group performing slightly better (66%) than the Baseline (58%).

Santosh Vempala, a computer science professor at Georgia Tech, has also studied hallucinations. “A language model is just a probabilistic model of the world,” he says, not a truthful mirror of reality. Vempala explains that an LLM’s answer strives for a general calibration with the real world—as represented in its training data—which is “a weak version of accuracy.” His research, published with OpenAI’s Adam Kalai, found that hallucinations are unavoidable for facts that can’t be verified using the information in a model’s training data.

Moreover, Midjourney apparently sought to suppress our findings, banning Southen from its service (without even a refund of his subscription fee) after he reported his first results, and again after he created a new account from which additional results were reported. It then apparently changed its terms of service just before Christmas by inserting new language: “You may not use the Service to try to violate the intellectual property rights of others, including copyright, patent, or trademark rights. Doing so may subject you to penalties including legal action or a permanent ban from the Service.” This change might be interpreted as discouraging or even precluding the important and common practice of red-team investigations of the limits of generative AI—a practice that several major AI companies committed to as part of agreements with the White House announced in 2023. (Southen created two additional accounts in order to complete this project; these, too, were banned, with subscription fees not returned.)

One user on X pointed to the fact that Japan has allowed AI companies to train on copyright materials. While this observation is true, it is incomplete and oversimplified, as that training is constrained by limitations on unauthorized use drawn directly from relevant international law (including the Berne Convention and TRIPS agreement). In any event, the Japanese stance seems unlikely to be carry any weight in American courts.

After a bit of experimentation (and in a discovery that led us to collaborate), Southen found that it was in fact easy to generate many plagiaristic outputs, with brief prompts related to commercial films (prompts are shown).

We will call such near-verbatim outputs “plagiaristic outputs,” because if a human created them we would call them prima facie instances of plagiarism.

PiVe: Prompting with Iterative VerificationImproving Graph-based Generative Capability of LLMs

更近期、相关和重要的记忆更有可能被提取出来

This illustration shows four alternative ways to nudge an LLM to produce relevant responses:Generic LLM - Use an off-the-shelf model with a basic prompt. The results can be highly variable, as you can experience when e.g. asking ChatGPT about niche topics. This is not surprising, because the model hasn’t been exposed to relevant data besides the small prompt.Prompt engineering - Spend time structuring the prompt so that it packs more information about the desired topic, tone, and structure of the response. If you do this carefully, you can nudge the responses to be more relevant, but this can be quite tedious, and the amount of relevant data input to the model is limited.Instruction-tuned LLM - Continue training the model with your own data, as described in our previous article. You can expose the model to arbitrary amounts of query-response pairs that help steer the model to more relevant responses. A downside is that training requires a few hours of GPU computation, as well as a custom dataset.Fully custom LLM - train an LLM from scratch. In this case, the LLM can be exposed to only relevant data, so the responses can be arbitrarily relevant. However, training an LLM from scratch takes an enormous amount of compute power and a huge dataset, making this approach practically infeasible for most use cases today.

基於變換器的雙向編碼器表示技術（英語：Bidirectional Encoder Representations from Transformers，BERT）是用於自然語言處理（NLP）的預訓練技術，由Google提出。[1][2]2018年，雅各布·德夫林和同事建立並發布了BERT。Google正在利用BERT來更好地理解使用者搜尋語句的語意。[3] 2020年的一項文獻調查得出結論：「在一年多一點的時間裡，BERT已經成為NLP實驗中無處不在的基線」，算上分析和改進模型的研究出版物超過150篇。[4] 最初的英語BERT發布時提供兩種類型的預訓練模型[1]：（1）BERTBASE模型，一個12層，768維，12個自注意頭（self attention head），110M參數的神經網路結構；（2）BERTLARGE模型，一個24層，1024維，16個自注意頭，340M參數的神經網路結構。兩者的訓練語料都是BooksCorpus[5]以及英語維基百科語料，單詞量分別是8億以及25億。

I am even more attuned to creative rights. We can address algorithms of exploitation by establishing creative rights that uphold the four C’s: consent, compensation, control, and credit. Artists should be paid fairly for their valuable content and control whether or how their work is used from the beginning, not as an afterthought.

Vector databases are used to retrieve relevant documents using similarity search. Vector databases can be standalone or embedded with the LLM application (e.g., Chroma embedded vector database). When structured (tabular) data is needed, an operational data store, such as a feature store, is typically used. Popular vector databases and feature stores are Weaviate and Hopsworks that both provide time-unlimited free tiers.

RAG LLMs can outperform LLMs without retrieval by a large margin with much fewer parameters, and they can update their knowledge by replacing their retrieval corpora, and provide citations for users to easily verify and evaluate the predictions.

With the embedding API, you can apply the innovation of embeddings, combined with the LLM capability, to various text processing tasks, such as:LLM-enabled Semantic Search: text embeddings can be used to represent both the meaning and intent of a user's query and documents in the embedding space. Documents that have similar meaning to the user's query intent will be found fast with vector search technology. The model is capable of generating text embeddings that capture the subtle nuances of each sentence and paragraphs in the document.LLM-enabled Text Classification: LLM text embeddings can be used for text classification with a deep understanding of different contexts without any training or fine-tuning (so-called zero-shot learning). This wasn't possible with the past language models without task-specific training.LLM-enabled Recommendation: The text embedding can be used for recommendation systems as a strong feature for training recommendation models such as Two-Tower model. The model learns the relationship between the query and candidate embeddings, resulting in next-gen user experience with semantic product recommendation.LLM-enabled Clustering, Anomaly Detection, Sentiment Analysis, and more, can be also handled with the LLM-level deep semantics understanding.

Grounded to business facts: In this demo, we didn't try having the LLM to memorize the 8 million items with complex and lengthy prompt engineering. Instead, we attached the Stack Overflow dataset to the model as an external memory using vector search, and used no prompt engineering. This means, the outputs are all directly "grounded" (connected) to the business facts, not the artificial output from the LLM. So the demo is ready to be served today as a production service with mission critical business responsibility. It does not suffer from the limitation of LLM memory or unexpected behaviors of LLMs such as the hallucinations.

In the new AI model, you ingest the data in real time, apply your models by reaching to one or multiple GPT services and action on the data while your users are in the online experience. These GPT models may be used for recommendation, classification personalization, etc., services on real-time data. Recent developments, such as LangChain and AutoGPT, may further disrupt how modern applications are deployed and delivered.

Let’s say, for example, you search for a very specific product on a retailer’s website, and the product is not available. An additional API call to an LLM with your request that returned zero results may result in a list of similar products. This is an example of a vector search, which is also known as a similarity or semantic search.

Conventional search works on keys. However, when the ask is a natural query, that sentence needs to be converted into a structure so that it can be compared with words that have similar representation. This structure is called an embedding. An embedding uses vectors that assign coordinates into a graph of numbers — like an array. An embedding is high dimensional as it uses many vectors to perform semantic search.

Plex is a scientific philosophy. Instead of claiming that science is so powerfulthat it can explain the understanding of understanding in question, we takeunderstanding as the open question, and set about to determine what scienceresults. [It turns out to be precisely the science we use every day, so nothingneed be discarded or overturned - but many surprises result. Some very simpleexplanations for some very important scientific observations arise naturally inthe course of Plex development. For example, from the First Definition, thereare several Plex proofs that there was no beginning, contrary to StephenHawking's statement that "this idea that time and space should be finite withoutboundary is just a proposal: it cannot be deduced from some other principle."(A Brief History of Time, p. 136.) The very concept of a "big bang" is strictlyan inherent artifact of our science's view of the nature of nature. There was no"initial instant" of time.]Axioms are assumptions. Plex has no axioms - only definitions. (Only) Noth-ing is assumed to be known without definition, and even that is "by definition" ,

A simple Python implementation of the ReAct pattern for LLMs.

A second, complementary, approach relies on post-hoc machine learning and forensic anal-ysis to passively identify statistical and physical artifacts left behind by media manipulation.For example, learning-based forensic analysis techniques use machine learning to automati-cally detect manipulated visual and auditory content (see e.g. [94]). However, these learning-based approaches have been shown to be vulnerable to adversarial attacks [95] and contextshift [96]. Artifact-based techniques exploit low-level pixel artifacts introduced during synthe-sis. But these techniques are vulnerable to counter-measures like recompression or additivenoise. Other approaches involve biometric features of an individual (e.g., the unique motionproduced by the ears in synchrony with speech [97]) or behavioral mannerisms [98]). Biomet-ric and behavioral approaches are robust to compression changes and do not rely on assump-tions about the moment of media capture, but they do not scale well. However, they may bevulnerable to future generative-AI systems that may adapt and synthesize individual biometricsignals.

First, under a highly permissive view, theuse of training data could be treated as non-infringing because protected works are not directlycopied. Second, the use of training data could be covered by a fair-use exception because atrained AI represents a significant transformation of the training data [63, 64, 65, 66, 67, 68].1Third, the use of training data could require an explicit license agreement with each creatorwhose work appears in the training dataset. A weaker version of this third proposal, is to atleast give artists the ability to opt-out of their data being used for generative AI [69]. Finally,a new statutory compulsory licensing scheme that allows artworks to be used as training databut requires the artist to be remunerated could be introduced to compensate artists and createcontinued incentives for human creation [70].

We strongly advocate conducting future studies to evaluate the performance of LLMs in annotating other linguistic phenomena

To solve the above problems, some researchers propose methods such as domain adaptation to learn transferable features and apply them in new domains

This paper presents COLT5 (ConditionalLongT5)

Over the past few years, many “efficient Trans-former” approaches have been proposed that re-duce the cost of the attention mechanism over longinputs (Child et al., 2019; Ainslie et al., 2020; Belt-agy et al., 2020; Zaheer et al., 2020; Wang et al.,2020; Tay et al., 2021; Guo et al., 2022). However,especially for larger models, the feedforward andprojection layers actually make up the majority ofthe computational burden and can render process-ing long inputs intractable

To benchmark GPT-4’s coding ability, OpenAI evaluated it on problems from Codeforces, a website that hosts coding competitions. Surprisingly, Horace He pointed out that GPT-4 solved 10/10 pre-2021 problems and 0/10 recent problems in the easy category. The training data cutoff for GPT-4 is September 2021. This strongly suggests that the model is able to memorize solutions from its training set — or at least partly memorize them, enough that it can fill in what it can’t recall.

This highlights one of the types of muddled thinking around LLMs. These tasks are used to test theory of mind because for people, language is a reliable representation of what type of thoughts are going on in the person's mind. In the case of an LLM the language generated doesn't have the same relationship to reality as it does for a person.What is being demonstrated in the article is that given billions of tokens of human-written training data, a statistical model can generate text that satisfies some of our expectations of how a person would respond to this task. Essentially we have enough parameters to capture from existing writing that statistically, the most likely word following "she looked in the bag labelled (X), and saw that it was full of (NOT X). She felt " is "surprised" or "confused" or some other word that is commonly embedded alongside contradictions.What this article is not showing (but either irresponsibly or naively suggests) is that the LLM knows what a bag is, what a person is, what popcorn and chocolate are, and can then put itself in the shoes of someone experiencing this situation, and finally communicate its own theory of what is going on in that person's mind. That is just not in evidence.The discussion is also muddled, saying that if structural properties of language create the ability to solve these tasks, then the tasks are either useless for studying humans, or suggest that humans can solve these tasks without ToM. The alternative explanation is of course that humans are known to be not-great at statistical next-word guesses (see Family Feud for examples), but are also known to use language to accurately describe their internal mental states. So the tasks remain useful and accurate in testing ToM in people because people can't perform statistical regressions over billion-token sets and therefore must generate their thoughts the old fashioned way.

Certainly it would not be possible if theLLM were doing nothing more than cutting-and-pasting fragments of text from its training setand assembling them into a response. But this isnot what an LLM does. Rather, an LLM mod-els a distribution that is unimaginably complex,and allows users and applications to sample fromthat distribution.
