In this tutorial, we walk you through setting up a fully functional bot in Google Colab that leverages Anthropic’s Claude model alongside mem0 for seamless memory recall. Combining LangGraph’s intuitive state-machine orchestration with mem0’s powerful vector-based memory store will empower our assistant to remember past conversations, retrieve relevant details on demand, and maintain natural continuity across sessions. Whether you’re building support bots, virtual assistants, or interactive demos, this guide will equip you with a robust foundation for memory-driven AI experiences. !pip install -qU langgraph mem0ai langchain langchain-anthropic anthropic First, we install and upgrade LangGraph, the Mem0 AI client, LangChain with its Anthropic connector, and the core Anthropic SDK, ensuring we have all the latest libraries required for building a memory-driven Claude chatbot in Google Colab. Running it upfront will avoid dependency issues and streamline the setup process. import os from typing import Annotated, TypedDict, List from langgraph.graph import StateGraph, START from langgraph.graph.message import add_messages from langchain_core.messages import SystemMessage, HumanMessage, AIMessage from langchain_anthropic import ChatAnthropic from mem0 import MemoryClient We bring together the core building blocks for our Colab chatbot: it loads the operating-system interface for API keys, Python’s typed dictionaries and annotation utilities for defining conversational state, LangGraph’s graph and message decorators to orchestrate chat flow, LangChain’s message classes for constructing prompts, the ChatAnthropic wrapper to call Claude, and Mem0’s client for persistent memory storage. os.environ["ANTHROPIC_API_KEY"] = "Use Your Own API Key" MEM0_API_KEY = "Use Your Own API Key" We securely inject our Anthropic and Mem0 credentials into the environment and a local variable, ensuring that the ChatAnthropic client and Mem0 memory store can authenticate properly without hard-coding sensitive keys throughout our notebook. Centralizing our API keys here, we maintain a clean separation between code and secrets while enabling seamless access to the Claude model and persistent memory layer. llm = ChatAnthropic( model="claude-3-5-haiku-latest", temperature=0.0, max_tokens=1024, anthropic_api_key=os.environ["ANTHROPIC_API_KEY"] ) mem0 = MemoryClient(api_key=MEM0_API_KEY) We initialize our conversational AI core: first, it creates a ChatAnthropic instance configured to talk with Claude 3.5 Sonnet at zero temperature for deterministic replies and up to 1024 tokens per response, using our stored Anthropic key for authentication. Then it spins up a Mem0 MemoryClient with our Mem0 API key, giving our bot a persistent vector-based memory store to save and retrieve past interactions seamlessly. class State(TypedDict): messages: Annotated[List[HumanMessage | AIMessage], add_messages] mem0_user_id: str graph = StateGraph(State) def chatbot(state: State): messages = state["messages"] user_id = state["mem0_user_id"] memories = mem0.search(messages[-1].content, user_id=user_id) context = "\n".join(f"- {m['memory']}" for m in memories) system_message = SystemMessage(content=( "You are a helpful customer support assistant. " "Use the context below to personalize your answers:\n" + context )) full_msgs = [system_message] + messages ai_resp: AIMessage = llm.invoke(full_msgs) mem0.add( f"User: {messages[-1].content}\nAssistant: {ai_resp.content}", user_id=user_id ) return {"messages": [ai_resp]} We define the conversational state schema and wire it into a LangGraph state machine: the State TypedDict tracks the message history and a Mem0 user ID, and graph = StateGraph(State) sets up the flow controller. Within the chatbot, the most recent user message is used to query Mem0 for relevant memories, a context-enhanced system prompt is constructed, Claude generates a reply, and that new exchange is saved back into Mem0 before returning the assistant’s response. graph.add_node("chatbot", chatbot) graph.add_edge(START, "chatbot") graph.add_edge("chatbot", "chatbot") compiled_graph = graph.compile() We plug our chatbot function into LangGraph’s execution flow by registering it as a node named “chatbot,” then connecting the built-in START marker to that node. Hence, the conversation begins there, and finally creates a self-loop edge so each new user message re-enters the same logic. Calling graph.compile() then transforms this node-and-edge setup into an optimized, runnable graph object that will manage each turn of our chat session automatically. def run_conversation(user_input: str, mem0_user_id: str): config = {"configurable": {"thread_id": mem0_user_id}} state = {"messages": [HumanMessage(content=user_input)], "mem0_user_id": mem0_user_id} for event in compiled_graph.stream(state, config): for node_output in event.values(): if node_output.get("messages"): print("Assistant:", node_output["messages"][-1].content) return if __name__ == "__main__": print("Welcome! (type 'exit' to quit)") mem0_user_id = "customer_123" while True: user_in = input("You: ") if user_in.lower() in ["exit", "quit", "bye"]: print("Assistant: Goodbye!") break run_conversation(user_in, mem0_user_id) We tie everything together by defining run_conversation, which packages our user input into the LangGraph state, streams it through the compiled graph to invoke the chatbot node, and prints out Claude’s reply. The __main__ guard then launches a simple REPL loop, prompting us to type messages, routing them through our memory-enabled graph, and gracefully exiting when we enter “exit”. In conclusion, we’ve assembled a conversational AI pipeline that combines Anthropic’s cutting-edge Claude model with mem0’s persistent memory capabilities, all orchestrated via LangGraph in Google Colab. This architecture allows our bot to recall user-specific details, adapt responses over time, and deliver personalized support. From here, consider experimenting with richer memory-retrieval strategies, fine-tuning Claude’s prompts, or integrating additional tools into your graph.

Shadow ForceThe Grey that’s about as shoddily assembled and nondescript as they come. Even the poster art looks like something you’d scroll by on Prime Video rather than a movie currently in theaters. Omar Sy and Kerry Washington star as Isaac and Kyrah, a couple on the run. Or, at least, half on the run. He’s introduced watching over their young son Ky (Jahleel Kamara); she’s first seen sniping a guy who appears to be in the midst of a raid by some soldier-looking guys. (Like so much of this confounding movie, it’s unclear). They used to be a part of the titular Force, a worldwide organization that, as villain Mark Strong describes, was responsible for taking out the “dirty laundry” – though who’s dirty laundry and what that entails is glossed over. A lotThe most egregious example of this vagueness comes with the Shadow Force itself: They’re introduced in a “putting the team together” montage and a dinner scene with a “funny” story, but none of their names are ever even spoken aloud. At times it feels as if the script – co-written by Carnahan and Leon Chills – has been hacked to bits. A third-act reversal comes basically out of nowhere, featuring a couple of guys we’ve seen before but whose function in the story is as wispy as the fog Isaac and Kyrah drive through. It comes to the point where it’s difficult to even care about anything happening onscreen, and by the time we get to an incoherently edited climax, the most I could muster up was “Sure, what the hell.” Sy and Washington don’t really have much chemistry together, but neither is wholly bad in their action-hero roles. The same can’t be said for Kamara, who always sounds like he’s reading his lines instead of delivering them, and is usually stuck with unfunny sitcom-style jokes that don’t grate so much as exist. Shadow Force GalleryIn some scenes, Carnahan manages to get Shadow Force’s heart rate just a bit above resting. There’s not enough of them though, and one at the beginning has the inspired (if ineffective) choice of holding tight on Ky’s face as the image strobes to the sound of gunfire, the carnage unfolding around him only glimpsed later on a security-camera screen. Everything about the sets looks cheap and generic, while the cinematography lurches from actually being kind of compelling to “why movie look like that." It would be frustrating if there were anything to really feel frustrated about, but it’s also not haphazard enough to reach any level of “how did this get made?” Mostly, Shadow Force is just kinda boring, more like the idea of an action movie than an actual one. One can easily imagine falling asleep during it and waking up not missing a thing, the movie evaporating from your memory the minute you leave the theater. There just isn’t really anything there – you know, kind of like a shadow.

As the producer and composer behind some of the biggest songs like "Beat It" and "Billie Jean"—not to mention the recipient of a whopping 28 Grammy Awards—Quincy Jones was nothing short of a musical legend. So, is it really a surprise that his real-estate portfolio was equally legendary? Six months after Jones passed away, his Bel Air home has officially be put on the market for a whopping $59.99 million. We've seen a lot of celebrity properties go on the market—sometimes, they stay unsold for years–but this home's nearly $60 million price tag is by no means cheap. But while this listing elicits lots of sticker shock, it uniquely captures Jones' architectural point of view.Anthony Barcelo"There are homes built for spec, and others that seem to trade hands often—but then there are homes like this, which almost never come to market," explains David Kramer, who is listing the site through his eponymous group at Compass. "Add to that the legacy of Quincy Jones, and it becomes not just a unique architectural offering, but a piece of cultural history.” Completed in the early aughts, the residence was built to bring a resort sensibility to California. In fact, Jones was reportedly inspired by a hotel in South Africa called the Palace of the Lost City—and tapped architect Gerald “Jerry” Allison to turn his vision into a real-estate reality. (Fun fact: Jones and Allison were exactly friends from high school, giving this passion project a personal touch.)Anthony BarceloClocking in at just under 25,000 square feet, this estate is anchored by a circular central wing that houses a spacious living room, wine cellar with tasting room, indoor garden area, as well as a game lounge and cabana that opens up to a resort-style pool. The east wing comprises the primary suite—which has multiple walk-in closets, a private balcony, and a dedicated exercise room—while the west wing has three additional suites. Oh, and did we mention the home also features an office with a reception area, screening room, and gallery?While this residence is by no means cheap, the Jones family hopes that the new owner loves the home as much as the late composer did. "Our family has a lifetime worth of wonderful memories and meaning imbued in this home," daughter Rashida Jones told the Wall Street Journal.

At CES 2025, Anker unveiled a rather interesting new battery bank. It’s extremely compact, offers up to 25,000mAh of capacity, and has multiple built in cables for ease of use. I’ve utilized this battery bank for many months, and I can confidently say its an easy purchase if you’re looking for an all-in-one solution for all of your Apple devices, MacBooks included. First things first, this power bank is highly versatile. It includes two built in USB-C cables. One is an up to 27-inch retractable cable, and the other is an 8-inch foldable cable, which also doubles as a strap. It also has two USB-C ports and an USB-A port for additional outputs. All in all, this power bank outputs up to 165W, though each USB-C connector is only capable of outputting 100W max. This Anker power bank comes in at just over a pound (555g), making it not too heavy to carry around. It’s by no means the lightest power bank you can own, but given the versatility – I think it’s justified. It also comes in at just 6 inches tall and under 2 inches wide, making it pretty compact to toss in a bag. As mentioned earlier, this power bank can recharge a MacBook. When it’s fully charged, it packs around 90Wh of capacity, leaving plenty of juice to fully cover a MacBook if needed. Anker says it’ll recharge a 16-inch MacBook Pro to 50% in just around half an hour. I think the more interesting part is the fact that it’ll fully cover a MacBook Air or 14-inch MacBook Pro if you’re away from power for an extended period of time. It’ll nearly cover a 16-inch MacBook Pro too, though not to 100%. All of that – in a form factor that can easily fit in your hand, makes this worth picking up. It also has a relatively nifty LCD screen, which’ll provide charging insights for your devices, and keep you up to date on the battery level of the power bank. It’s also safe to carry on a plane, making it the ultimate power bank for all of your Apple devices, provided you’re okay with the slightly hefty weight. If you’d like one of these power banks, you can pick one up on Amazon today. It’s available in two colors, silver and black. The silver one is available for a lower price at the time of writing.

Talk to a teacher lately, and you'll probably get an earful about AI's effects on student attention spans, reading comprehension, and cheating.As AI becomes ubiquitous in everyday life — thanks to tech companies forcing it down our throats — it's probably no shocker that students are using software like ChatGPT at a nearly unprecedented scale. One study by the Digital Education Council found that nearly 86 percent of university students use some type of AI in their work.That's causing some fed-up teachers to fight fire with fire, using AI chatbots to score their students' work. As one teacher mused on Reddit: "You are welcome to use AI. Just let me know. If you do, the AI will also grade you. You don't write it, I don't read it."Others are embracing AI with a smile, using it to "tailor math problems to each student," in one example listed by Vice. Some go so far as requiring students to use AI. One professor in Ithaca, NY, shares both ChatGPT's comments on student essays as well as her own, and asks her students to run their essays through AI on their own.While AI might save educators some time and precious brainpower — which arguably make up the bulk of the gig — the tech isn't even close to cut out for the job, according to researchers at the University of Georgia. While we should probably all know it's a bad idea to grade papers with AI, a new study by the School of Computing at UG gathered data on just how bad it is.The research tasked the Large Language Model (LLM) Mixtral with grading written responses to middle school homework. Rather than feeding the LLM a human-created rubric, as is usually done in these studies, the UG team tasked Mixtral with creating its own grading system. The results were abysmal.Compared to a human grader, the LLM accurately graded student work just 33.5 percent of the time. Even when supplied with a human rubric, the model had an accuracy rate of just over 50 percent.Though the LLM "graded" quickly, its scores were frequently based on flawed logic inherent to LLMs."While LLMs can adapt quickly to scoring tasks, they often resort to shortcuts, bypassing deeper logical reasoning expected in human grading," wrote the researchers."Students could mention a temperature increase, and the large language model interprets that all students understand the particles are moving faster when temperatures rise," said Xiaoming Zhai, one of the UG researchers. "But based upon the student writing, as a human, we’re not able to infer whether the students know whether the particles will move faster or not."Though the UG researchers wrote that "incorporating high-quality analytical rubrics designed to reflect human grading logic can mitigate [the] gap and enhance LLMs’ scoring accuracy," a boost from 33.5 to 50 percent accuracy is laughable. Remember, this is the technology that's supposed to bring about a "new epoch" — a technology we've poured more seed money into than any in human history.If there were a 50 percent chance your car would fail catastrophically on the highway, none of us would be driving. So why is it okay for teachers to take the same gamble with students?It's just further confirmation that AI is no substitute for a living, breathing teacher, and that isn't likely to change anytime soon. In fact, there's mounting evidence that AI's comprehension abilities are getting worse as time goes on and original data becomes scarce. Recent reporting by the New York Times found that the latest generation of AI models hallucinate as much as 79 percent of the time — way up from past numbers.When teachers choose to embrace AI, this is the technology they're shoving off onto their kids: notoriously inaccurate, overly eager to please, and prone to spewing outright lies. That's before we even get into the cognitive decline that comes with regular AI use. If this is the answer to the AI cheating crisis, then maybe it'd make more sense to cut out the middle man: close the schools and let the kids go one-on-one with their artificial buddies.Share This Article

"Play Borderlands 4 first and understand the choices we've made," Randy Pitchford tells fans querying minimap removal "You still have the big map. It's one click away." Image credit: Gearbox News by Vikki Blake Contributor Published on May 10, 2025 Gearbox CEO Randy Pitchford has revealed Borderlands 4 - which boasts the biggest Borderlands map to date "by far" - has no minimap because the team "wants you to play the game and not play the map". Addressing fans queries and questions on a panel at PAX East yesterday, Pitchford implored we "play the game first and understand the choices [the development team has] made" before passing judgement on changes Gearbox has made to the shooter's head's up display (HUD). Gearbox Main Theater Show at PAX East 2025!Watch on YouTube "We made a big freaking world," Pitchford explained, as transcribed by PC Gamer. "And a lot of the things you do can be local space, but a lot of the things you do or want to do are out there, and a local space map is not a good way to navigate when you're thinking about objectives and opportunities - several at the same time that might be miles away - and a compass really helps us do that. "We want you to play the game and not play the map," he added. "So we made a commitment, and we put all of that investment into this compass system, and you still have the big map. It's one click away. And we put more cool stuff in there than we've ever done before. We even have, like, an AI-driven kind of navigation system that will give you a GPS on the big map to show you the line of where you can go." That said, Pitchford said the team was "open to thinking about things in the future" and implored players to do the same. "[P]lay the game first and understand the choices we've made, and I think you'll see and understand when you realise how big this world is and how playing the game in the world is better than playing the map. "We're on the offense, you guys," he added. "Sometimes we're like, white-knuckling to the landing, you know? And we've got a lot of work to do. We're working our asses off. But the momentum is insane. The velocity is insane. I don't think we've ever been in a better spot this far from launch as we are with Borderlands 4." Borderlands 4, as we learned a couple of weeks ago, is now arriving earlier than expected on 12th September, and developer Gearbox recently shared more of its latest looter shooter in a new PlayStation showcase. It showed off a couple of new Vault Hunters, some of its new weapons, new traversal mechanics, its new planet, and more all to whip-up enthusiasm for what creative director Graeme Timmins called "hands-down our best Borderlands ever".

Welcome back to Week in Review! We’ve got lots of news for you this week: There were CEO shake-ups at Instacart and 11x; the web series is back — kind of; Threads is getting video ads; and much more. Let’s get to it! Big move: Instacart CEO Fidji Simo will become OpenAI’s CEO for Applications, the company said this week. Simo is already on the OpenAI board. She’ll be tasked with helping OpenAI in scaling “traditional” company functions, CEO Sam Altman said, but he didn’t provide any details on what that means. Speaking of OpenAI: The company decided that its nonprofit division will retain control over its for-profit organization after initially announcing that it planned to convert to a for-profit organization. OpenAI says that it made the decision “after hearing from civic leaders and engaging in constructive dialogue with the offices of the Attorney General of Delaware and the Attorney General of California.” And speaking of CEO moves: 11x CEO Hasan Sukkar announced that he’s stepping down and moving into a “non-executive chairman” position. In March, TechCrunch reported that 11x had been showing off on its website customer logos of companies that were not active customers, and one of those companies was threatening to sue over the matter. This is TechCrunch’s Week in Review, where we recap the week’s biggest news. Want this delivered as a newsletter to your inbox every Saturday? Sign up here.

Tesla has three months to file a response, or the office will abandon the application.  No thanks: Speaking onstage at Stripe’s annual Sessions conference in San Francisco on Tuesday, Meta CEO Mark Zuckerberg laid out his plans to automate the entire ad industry with a black-box, end-to-end AI ad tool. As Maxwell Zeff reports, “It’s an open question as to what AI ad testing will do to Meta’s platforms from a user experience point of view, considering they’re already brimming with generative AI slop.” Techcrunch event Exhibit at TechCrunch Sessions: AI Secure your spot at TC Sessions: AI and show 1,200+ decision-makers what you’ve built — without the big spend.

We’re back, baby: Before the rise of vertical video, scripted web series on YouTube were successful enough to spin out into cult-favorite TV shows like “Broad City,” “Insecure,” and “Letterkenny.” Now the web series is back, but it lives on a new platform: TikTok.  Goodbye to a real one: Bill Gates said Thursday that the Gates Foundation will have just 20 years to exhaust its coffers and wind down operations. He has pledged to donate 99% of his fortune, which today is worth an estimated $107 billion, to the foundation. Analysis Image Credits:Stefano Guidi / Getty Images What’s next for OpenAI: OpenAI’s new restructuring plan could satisfy regulators and investors who have invested heavily in the company hoping for future profits. But it might also disrupt OpenAI’s future ambitions, especially regarding a potential IPO.
