🔍 Some standout insights from his exciting 𝐑𝐂𝐓 approach:
• 🧠 𝐇𝐢𝐠𝐡-𝐬𝐤𝐢𝐥𝐥𝐞𝐝 𝐬𝐭𝐮𝐝𝐞𝐧𝐭𝐬 𝐛𝐞𝐧𝐞𝐟𝐢𝐭 𝐦𝐨𝐫𝐞: GenAI improved debate performance far more for merit scholarship recipients and top baseline performers
• ⚖️ 𝐍𝐨𝐭 𝐚 𝐥𝐞𝐯𝐞𝐥𝐢𝐧𝐠 𝐭𝐨𝐨𝐥: Contrary to prior studies, ChatGPT did not help low-performers catch up

🔍 Some standout insights from their 𝐭𝐡𝐞𝐨𝐫𝐲 + 𝐬𝐢𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧:
• ✅ 𝐏𝐫𝐢𝐜𝐞𝐬: AI traders decode prices and learn portfolio strategies that qualitatively mirror rational benchmarks
• ❌ 𝐄𝐱𝐭𝐞𝐫𝐧𝐚𝐥𝐢𝐭𝐢𝐞𝐬: but when multiple AIs interact, they interfere with one another’s learning creating a negative externality

He presented “(𝘋𝘦𝘦𝘱) 𝘓𝘦𝘢𝘳𝘯𝘪𝘯𝘨 𝘵𝘰 𝘛𝘳𝘢𝘥𝘦”, co-authored with Ivan Gufler (@UniLUISS) and Emanuele Tarantino (@UniLUISS & European Commission). The work digs into how AI traders—using deep reinforcement learning—respond to price signals, interact with each other, and influence market outcomes 📚

8.𝐌𝐮𝐥𝐭𝐢-𝐚𝐠𝐞𝐧𝐭? Use a manager or task handoffs, but don’t overcomplicate.
9.𝐆𝐮𝐚𝐫𝐝𝐫𝐚𝐢𝐥𝐬 𝐚𝐫𝐞 𝐧𝐨𝐧-𝐧𝐞𝐠𝐨𝐭𝐢𝐚𝐛𝐥𝐞: protect against bad input, risky actions, and misuse.
10.𝐃𝐞𝐬𝐢𝐠𝐧 𝐟𝐨𝐫 𝐡𝐮𝐦𝐚𝐧𝐬: test early, expect failure, always have a backup plan.

4.𝐏𝐢𝐜𝐤 𝐭𝐡𝐞 𝐫𝐢𝐠𝐡𝐭 𝐦𝐨𝐝𝐞𝐥: test, explore with GPT-4, then optimize for speed/cost.
5.𝐓𝐨𝐨𝐥𝐬 𝐦𝐚𝐭𝐭𝐞𝐫: agents need reliable tools to access data and take action.
6.𝐈𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧𝐬 𝐚𝐫𝐞 𝐞𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠: vague = chaos. Be clear and specific.
7.𝐒𝐭𝐚𝐫𝐭 𝐬𝐦𝐚𝐥𝐥 — one solid agent with tools often beats a whole swarm.

Here are 10 key takeaways compiled by the great Hesam @Hesamation:
1.𝐀𝐠𝐞𝐧𝐭𝐬 ≠ 𝐰𝐨𝐫𝐤𝐟𝐥𝐨𝐰𝐬: agents act autonomously; most LLM apps need an input.
2.𝐔𝐬𝐞 𝐭𝐡𝐞𝐦 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐡𝐚𝐫𝐝 𝐬𝐭𝐮𝐟𝐟: messy data, dynamic rules, real decisions.
3.𝐂𝐨𝐫𝐞 𝐫𝐞𝐜𝐢𝐩𝐞 = brain (model), tools, and clear instructions.

@OpenAI I just released a practical guide to building 𝐀𝐈 𝐚𝐠𝐞𝐧𝐭𝐬 — and it’s genuinely useful. It is solid guidance that helps you get things working. ⚙️🤖

If you’re working with LLMs or thinking about agent-based products, it’s well worth the read:

Google released a 69-page whitepaper that dives deep into prompt design for a wide range of applications:

In the past two weeks, both Google and OpenAI have dropped major resources on prompt engineering — a clear sign of how fast this field is evolving and how central it’s becoming for anyone working with LLMs. ⚡🤖

Key insights from Loiacono’s Uganda field experiment:
• Tender info alone doesn’t lift firm participation
• Fixing misperceptions about public sector integrity boosts bids & contracts

We hosted Francesco Loiacono from @EBRD
at @ieuniversity.bsky.social 's Econ & Finance Seminar. He shared "Do Info Frictions & Corruption Perceptions Kill Competition?"—a sharp study on how mistrust, not info access, limits firms in public procurement. Engaging talk!
