We’re building long-run intelligence: AI systems that can work and predict at civilisation-scale time horizons.

Introducing Reinforcement Learning from Collective Rewards (RLCR).

RLCR is a recipe that trains language models as agent organisations, which share a message board and workspace. We use it to train Avalon-M1-Mini (120B) and study its behaviour.

We find a number of interesting results, including:

🛠️ Learnt organisational hierarchies and divisions of labour
🕵️ Increased collective verification, through hires of verifiers and testers
👥 The rise of collective thinking, where agents think more about other agents and how to help them

We believe RLCR can provide a laboratory for studying collective intelligence and multi-agent safety.

Blog post and technical report 👇

[General Reasoning @GenReasoning]

Read below for a summary of our findings and our technical report.

This is still under revision as we train Avalon-M1-Mini. We are a small team, so please be patient as we get back to you on any questions, or make updates.

@petergostev makes experiments way more reproducible, its a nice way to guarantee that solution on the live internet won’t leak your evals, and prevents hacking.

it’s not a big uplift if you already have your own search engine.

General Reasoning folks are even offering it as a service:

Details on how to try BackSearch out here: https://t.co/bStgCDU8qd

[General Reasoning @GenReasoning]

🔍 Introducing BackSearch.

LLMs are increasingly asked to predict the future, but a good backtest requires a snapshot of the internet at a point in time.

BackSearch allows LLMs to search the web as it was on a particular date. It’s great for:

🔮 Forecasting and prediction markets.
📈 Quantitative finance.
🌍 RL environments that simulate the world.
🥶 Freezing websearch for benchmark reproducibility

We’re releasing a narrow slice of our index to begin with, focused on the news domain for 2026. Based on feedback we’ll open up more of our index in subsequent releases.

OpenReward integration for FutureSim by @ShashwatGoel7 and team!

👇 Try it it out

[Shashwat Goel @ShashwatGoel7]

Major FutureSim updates!

🥽 Visualized trajectories: extremely long horizon, 1000s of actions per run and dozens of compactions, with summaries! Goldmine of interesting agent behaviors across Fable 5, GPT 5.5, GLM 5.2 etc!

📈 @OpenReward integration! You can now use FutureSim, incl. on your own data, with our favourite standard! The @GenReasoning was super supportive in making this happen!

Some cool observations in 🧵

[General Reasoning @GenReasoning]

Because of backtest variance, we also record a process-based rubric measure called "sophistication", which we track over time. This uses a human expert rubric to judge the sophistication of the strategies employed.

GLM-5.2 shows impressive sophistication compared to other open models, although it still does not surpass the closed SoTA on this metric for any time this year.

You can see the full leaderboard and more analysis here:

https://t.co/xew8Jm4NUB

[General Reasoning @GenReasoning]

We evaluated recent open models on KellyBench.

Here is what we found:

🏆 GLM 5.2 is new open source SoTA, but still loses -30% on average over 5 runs.
📈 We estimate GLM 5.2 is 6+ months behind the frontier based on KellyBench and internal quant evaluations. (Note: we have not evaluated Fable)
🌗 Kimi K2.6 slightly improves on Kimi K2.5 but still struggles at -60% average RoI.
🐈 Recent Mistral models struggle, obtaining mean RoIs of -78% and -99% respectively.

Train on OpenReward environments with TRL! 👇

[General Reasoning @GenReasoning]

We've updated the leaderboard with GPT-5.5 results:

https://t.co/nCkScbvHsn

TLDR: 30% strategy sophistication (new SoTA), much more efficient than GPT-5.4, but still in the red and systematically underperforming human approaches.

[General Reasoning @GenReasoning]

New models on KellyBench, the benchmark for long-horizon sequential decision making.

🎆 Claude Opus 4.7 - new state-of-the-art, with the highest strategy sophistication recorded on the benchmark (28.5%). But still loses -3.7% on average over five seeds.

🐋 DeepSeek V4 Pro - shows strong feature development capabilities, but scores poorly on overfitting rubrics which harms it in deployment (-47%).

We’re also thankful that KellyBench was featured on the front page of the FT last month!

🌍 Last month we hosted the Complex Worlds Hackathon in London.

Participants built an impressive range of environments, spanning synthetic game pipelines, arable farm management, dynamic vehicle routing, hospital triage, robotics, cybersecurity, and more.

Congrats to our winners, Julie Huang and Khalid A!
