What is the LLM Council?

The LLM Council is Heavy3's multi-agent AI architecture built on three pillars: (1) different SOTA models with unique training and biases, (2) different adversarial roles that attack problems from different angles, and (3) different sources of truth—GPT searches Bing, Gemini searches Google, Grok searches X. True verification requires diversity at every layer.

How can Heavy3 help me verify my decisions?

Heavy3's LLM Council reviews your critical decisions like a board of expert advisors. Upload your strategy document, contract, or code and get feedback on blind spots, weak arguments, and risks—before you commit. Built by a scientist who needed accuracy for high-stakes decisions.

Why use multiple AI models instead of just ChatGPT?

Research shows multi-model ensembles beat single models by 13.2% on benchmarks. Each AI has different training and blind spots. When GPT-5, Gemini 3.1, and Grok 4 all agree your argument is weak—fix it. When they disagree, you see the risk before you commit.

Heavy3 was built by a scientist and engineer who regularly makes high-stakes decisions requiring depth and accuracy. After years of manually cross-checking AI responses before committing to important decisions, he built Heavy3 to automate the workflow.

What can Heavy3 verify?

Heavy3 verifies: business strategy and roadmaps, contracts and legal documents, pitch decks and investor materials, code architecture decisions, OKRs and planning documents—any high-stakes decision where accuracy matters and blind spots are costly.

Deep Audit is Heavy3's adversarial agentic research engine—the only one that makes AI agents actively argue with each other. Each agent gets a cognitive role: the Analyst digs deep, the Skeptic challenges assumptions, and the Lateral Thinker explores angles you didn't consider. They run 6 chained rounds of web research with parallel tool use, then a Synthesizer cross-examines all findings and delivers a verdict with academic citations. It catches what a single AI would confidently get wrong.

Is my data secure and private?

Yes—your data is encrypted, isolated, and never used for AI training. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). We access AI models through OpenRouter with all privacy protections enabled: training disabled, prompt logging disabled. We never sell your data or use it for advertising. Staff access is limited to debugging and support only. SOC 2 compliant infrastructure with no tracking cookies. Built by a scientist who understands you're sharing sensitive information.

Can you suggest a 7-day travel itinerary to China for first-time visitors? Don't rush too much. I want to visit the best places for first-time visitors and take into account safety. How to avoid scams and so on. What is your recommendation?

### Executive Summary This report synthesizes a comprehensive 7-day travel plan for first-time visitors to China, balancing iconic sightseeing with practical safety and logistical considerations. The consensus recommendation is a modified **"Capital & Coast" itinerary (Beijing & Shanghai)**, which offers the best balance of historical and modern experiences while minimizing travel fatigue and risk. For those seeking a more ambitious trip, the classic **"Golden Triangle" (Beijing, Xi'an, Shanghai)** is viable but requires meticulous planning and acceptance of a faster pace. Critical pre-trip actions include securing the correct **Standard Tourist (L) Visa**, setting up **Alipay/WeChat Pay**, and understanding region-locked visa-free transit rules. China remains generally safe for tourists, with petty scams being the primary concern, mitigated by awareness and digital preparedness. ### Detailed Findings #### 1. Core Itinerary Options **Option A: The Modified "Capital & Coast" (Recommended for a Relaxed Pace)** * **Rationale:** Maximizes contrast between ancient imperial power and futuristic modernity with only one intercity transfer, reducing logistical stress and jet lag impact. * **Routing:** Open-jaw flights into Beijing, out of Shanghai. * **Beijing (4 Days):** Forbidden City (book 7 days in advance), Mutianyu Great Wall (avoid crowded Badaling), Temple of Heaven, hutong neighborhoods, Qianmen/Dashilar area. * **Transfer:** High-speed train (G-Train) from Beijing to Shanghai (~4.5 hours), favored over domestic flights for punctuality. * **Shanghai (3 Days):** The Bund skyline, Lujiazui (Shanghai Tower), Yu Garden, French Concession, optional day trip to Zhujiajiao water town or Suzhou. **Option B: The Classic "Golden Triangle" (For Maximum Landmark Coverage)** * **Rationale:** Covers China's three most iconic destinations for first-timers but involves three cities in seven days. * **Routing:** Beijing → Xi'an → Shanghai. * **Beijing (3 Days):** Forbidden City, Mutianyu Great Wall, Tiananmen Square, hutongs. * **Xi'an (2 Days):** Terracotta Army (arrive early), Ancient City Wall (bike at sunset), Muslim Quarter (beware of food scams). * **Shanghai (2 Days):** The Bund, Yu Garden, French Concession. #### 2. Critical Logistics & Pre-Trip Setup * **Visa Requirements (CRITICAL):** * **Standard Tourist (L) Visa:** **Required** for the multi-city itineraries above. The 144/240-hour Visa-Free Transit policy is **region-locked**. If you enter Beijing, you must stay within the Beijing-Tianjin-Hebei region and cannot travel to Shanghai or Xi'an [1][4]. * **Visa-Free Transit:** Useful only for single-city stays or specific regional tours. The policy has been expanded to 55 countries and extended to December 31, 2026 [1]. * **Digital Payment Wall:** * China is a cashless society. Foreign credit cards (Visa/Mastercard) are rarely accepted at point-of-sale. * **Mandatory Setup:** Download **Alipay** and/or **WeChat** before departure. Link your foreign credit card. Be aware of single-transaction limits (~¥3,000 or ~$415) and ask merchants to split larger bills if needed [2][7]. * **Cash:** Carry some RMB for emergencies, but its use has declined significantly [3]. * **Connectivity & The "Great Firewall":** * Google, Facebook, Instagram, WhatsApp, and many Western news sites are blocked. * **Solution:** Do not rely on hotel VPNs. Purchase an **international eSIM** (e.g., Airalo) or a roaming package from your home carrier to bypass restrictions automatically. * **Tickets & Bookings:** * **Forbidden City Tickets:** Sell out within minutes. Must be booked **exactly 7 days in advance at 8:00 PM Beijing Time** via the official WeChat mini-program or website. Have a backup plan (e.g., Jingshan Park) [5]. * **High-Speed Trains:** Book in advance via Trip.com or the China Railway app. Clean, efficient, and often preferable to flights. #### 3. Safety Profile & Scam Prevention * **Official Travel Advisories:** The U.S. State Department lists Mainland China at **Level 2: Exercise Increased Caution** (as of Nov 27, 2024), citing risks of arbitrary enforcement of local laws and exit bans [6]. The UK Foreign Office provides detailed advice on common scams and legal sensitivities [4]. * **Common Tourist Scams & Countermeasures:** 1. **Tea House / Art Student Scam:** A friendly English speaker invites you for tea or to an art show, resulting in an exorbitant bill (¥300-1000+). **Rule:** Politely decline and walk away. Do not follow strangers to a second location [4][8]. 2. **Fake / "Cheap" Tour Scams:** Aggressive touts near major sights (e.g., Tiananmen Square) offer cheap tours to the Great Wall. These often involve forced shopping stops and low-quality service. **Rule:** Book tours through your hotel or reputable platforms like Viator or Klook [8]. 3. **Taxi & Ride-Hailing Scams:** Includes "black taxis" at airports, meter manipulation, and inflated fares. **Rule:** Use official taxi queues, insist on the meter ("Qǐng dǎ biǎo"), or use the **Didi** app (available in English within Alipay) for price transparency [8]. 4. **QR Code Tampering:** Fraudulent stickers placed over legitimate QR codes on rental bikes or payment posters. **Rule:** Only scan codes within official apps or from clearly official sources [4]. 5. **Xinjiang Cake (切糕) Scam:** In food markets like Xi'an's Muslim Quarter, vendors sell nut cakes priced by "piece" but charge by weight after cutting, leading to massive bills. **Rule:** Confirm the total price unequivocally before allowing any cutting. * **General Safety:** Violent crime against tourists is rare. Practice standard precautions: beware of pickpockets in crowds, don't leave drinks unattended, and carry your passport at all times (random police checks are possible). #### 4. Health & Environmental Considerations * **Air Pollution:** Winter months (Dec-Feb) in northern cities like Beijing can see high PM2.5 levels. Check the AQI and wear an N95 mask if needed. * **Drug Warning:** China has a zero-tolerance policy. A positive test for any drug, even if consumed legally abroad, can lead to detention, fines, and deportation. ### Analysis & Insights Synthesizing the advisors' views reveals a clear tension between breadth and depth of experience. The Direct Expert's Golden Triangle is the traditional "greatest hits" package but, as the Critical Analyst rightly stresses, turns a 7-day trip into a logistical marathon with high fatigue risk. The Lateral Thinker's insight to "master 2-3 cities deeply" aligns with the modern preference for immersive travel over checklist tourism. The **Beijing-Shanghai split emerges as the superior strategic choice** for a first-time, "don't rush" visit. It provides the essential contrast between ancient and modern China, which is the core narrative for a first trip. It reduces complex travel days from two to one, allocates more time for cultural absorption, and simplifies the critical digital and logistical setup process. The Terracotta Warriors in Xi'an are undoubtedly magnificent, but the opportunity cost of adding a third city is significant stress and superficiality. The research underscores that **the biggest risks are bureaucratic and digital, not physical**. Failure to understand visa rules or to set up mobile payments will cause far more disruption than any street scam. Success hinges on pre-trip preparation: securing the correct visa, booking key attractions, and installing essential apps. ### Considerations & Caveats * **The Visa-Free Trap:** Attempting a multi-city tour on a 144/240-hour transit visa is the single most likely planning error that will result in denied entry or legal trouble. **You must get a Standard L Visa.** * **Payment Failure Mode:** Arriving without Alipay/WeChat Pay set up will render you unable to pay for taxis, street food, and even many sit-down restaurants, creating immediate and severe friction. * **Connectivity Blackout:** Assuming you'll access Google Maps or WhatsApp could leave you lost and unable to communicate. An eSIM/data plan is non-negotiable. * **Overambitious Scheduling:** The Golden Triangle in 7 days means packing/unpacking three times, with two half-days lost to travel. This contradicts the user's "don't rush" directive and increases exposure to transport hiccups. * **Cultural & Legal Sensitivity:** Be mindful of laws regarding photography of military installations, drone use, and political discourse. Exit bans, while rare for tourists, are a documented tool used in civil and commercial disputes. ### Alternative Perspectives * **Nature-Focused Alternative (Beijing + Guilin/Yangshuo):** Swap Shanghai for the stunning karst landscapes of Guilin. Offers a mix of imperial history and iconic natural beauty (Li River cruise, Yangshuo countryside). A more relaxing and visually spectacular alternative to urban centers. * **The "Deep Dive" Single-City Option:** Consider spending all 7 days in one region for maximum immersion. For example, **Beijing plus a 2-day trip to Chengde or the Great Wall at Jinshanling**, or **Shanghai with extended trips to Hangzhou's West Lake and Suzhou's gardens**. * **Strategic Splurges:** Invest in a **private guide for key historical sites** (Forbidden City, Terracotta Army). The context they provide dramatically enhances understanding. Consider **boutique hotels in hutongs or the French Concession** for a more authentic cultural experience. * **Timing is Everything:** Avoid Chinese public holidays (National Day in October, Chinese New Year in Jan/Feb). **Autumn (September-November)** is widely recommended for pleasant weather and beautiful scenery. ### Conclusion For a first-time visitor to China seeking a rich but manageable experience that prioritizes safety and a relaxed pace, the **4-night Beijing / 3-night Shanghai itinerary is the definitive recommendation.** This "Capital & Coast" route delivers the essential contrast of ancient and modern China, minimizes stressful travel logistics, and allows adequate time for cultural engagement and recovery from jet lag. It provides a robust framework within which you can confidently navigate the country's unique digital ecosystem and avoid common pitfalls. **Final Checklist Before You Go:** 1. Obtain a **Standard Tourist (L) Visa**. 2. Download and set up **Alipay** and **WeChat**, linking a credit card. 3. Arrange an **international eSIM/data plan**. 4. Book **Forbidden City tickets** exactly 7 days in advance. 5. Book **high-speed train tickets** from Beijing to Shanghai. 6. Enroll in the **STEP program** (U.S. citizens) for embassy alerts. 7. Have your hotel addresses saved **in Chinese characters**. 8. Memorize the core scam avoidance rule: **Politely decline invitations from friendly strangers to go to a second location.** ### References [1] China widens visa-free access in latest opening-up move. https://english.www.gov.cn/news/202511/04/content_WS69094ae0c6d00ca5f9a07472.html [2] Alipay/WeChat Payment Limits for Foreign Cards Explained (2025). https://payinchinaguide.com/alipay-wechat-limits-foreign-cards/ [3] In China, coins and banknotes have all but disappeared. https://www.lemonde.fr/en/economy/article/2025/06/28/in-china-coins-and-banknotes-have-all-but-disappeared_6742800_19.html [4] Safety and security — China travel advice (GOV.UK). https://www.gov.uk/foreign-travel-advice/china/safety-and-security [5] Beijing Cracks Down on Forbidden City Scalpers. https://www.sixthtone.com/news/1013488 [6] China Travel Advisory. https://travel.state.gov/content/travel/en/traveladvisories/traveladvisories/china-travel-advisory.html [7] Digital payments enhance travel experience - Chinadaily.com.cn. https://www.chinadaily.com.cn/a/202502/18/WS67b3e50aa310c240449d5d05.html [8] Common Scams and Tourist Traps in China (Must Know Before You Go). https://www.chinadiscovery.com/travel-guide/common-scams-tourist-traps-in-china.html
