2/ Comparable results: standardized interfaces and caps Most evals assume single-agent, fully observed, short-horizon tasks. Real agents face partial observability (POMDP), non-stationary opponents, and strategic incentives. Without standardized interfaces, seeds, and caps,

3/ What’s in MindGames (domains & skills) MindGames spans the core modes of social reasoning you actually need in products. Hidden-information co-op forces agents to coordinate under uncertainty by inferring teammates’ private state from constrained signals. Adversarial

4/ The protocol: standardized turns, hard budgets, audit-ready logs Each turn exposes a structured observation that includes the public state and any private information. The agent reasons privately, may send a message over a rate-limited channel with token and latency caps,

5/ From social behavior into numbers Beyond win rate and utility, we quantify communication quality (truthfulness, relevance, and persuasion) using blinded judge models and rule-based checks. Moreover, we also track theory-of-mind proxies by comparing an agent’s inferred

6/ Where agents crack under pressure LLMs coordinate on short, low-entropy scenarios, but performance drops when beliefs must be revised over long horizons, when opponents deviate from templated play, or when incentives flip mid-game and contracts need renegotiation. Typical

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Fascinating shift moving from data reproduction to emergent reasoning through interaction-based learning. Games are such a rich sandbox for testing contextual intelligence. Can’t wait to see where this leads.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL The real challenge with social reasoning arenas is distinguishing between agents that genuinely understand strategic dynamics versus those that pattern-match from training data. Long-horizon scenarios force agents to maintain coherent mental models of other players, which current

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Wild stuff 🤔 Wonder how these agents will handle situations where lying actually pays off though will they stay “honest” or just play to win?

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL long horizons + social reasoning = the real stress test for LLMs. curious to see which agents adapt when the game flips

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Sentient came really prepared, it's not a coincidence that they won AI startup of the year at all, it's a testament to how awesome the tech is.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL This is the kind of innovation that keeps AI exciting, This framework could foster a more sustainable ecosystem where open models remain usable without sacrificing control or transparency.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL mindgames really is an interesting one, i specifically love how it teaches agents to think strategically, negotiate, and adapt in unpredictable settings.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL I can hardly believe this is real. Letting AI learn in arenas is completely revolutionary! I'm confident that this approach will let agents develop through real strategy and social dynamics, hence developing toward true AGI.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Damn not only Meta but also Princeton and MIT? This is crazy🔥

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL The whole team working overtime... I'm so impressed by the level of collaboration and the building spirit has never been stronger. gSenti

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL The team is Steady shipping 🔥

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL This sounds like an exciting initiative! Collaborating with such prestigious institutions will surely yield impactful advancements in AI. Looking forward to seeing the results of this innovative approach. les go @SentientAGI

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL there we go again perfect form of partnership for expansion

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL The fastest way to improve AI today is to enable agents to learn in arenas that encourage long-term planning and social thinking. This is a great and exciting plan

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Finally, a real benchmark that treats AI reasoning like what it actually is dynamic, social, and messy. MindGames feels like the missing piece between synthetic evals and real-world intelligence.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Sentient really gave its all into the papers and with each one coming out I see why all 4 got accepted. Kudos to the Sentient Team

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL This is a good way to improve how AIs think and interact

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL this sounds promising for ai's future. what scenarios do you predict?

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL This MindGames arena could finally benchmark how LLMs handle real-world supply chain haggling where one bad bluff tanks the whole deal. Bullish on spotting those fragile spots early.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Bluffing, alliances, betrayal — MindGames is where LLMs learn to think, plan, and deceive. ♟️

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL MindGames isn’t just another benchmark it’s a full stress test for social intelligence. The way it tracks truthfulness, persuasion, and belief modeling shows how far we’ve come from simple “win rate” metrics.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL God alone knows the exact number of researchers Sentient has brought on board with this level of dedication, failure simply isn’t an option.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Excited to see how this plays out 😁 AI GAMES

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Sentient is turning AI into real “players” with strategy and social reasoning.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL These kinds of test arenas are exactly what will drive smarter, more capable AI agents.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Sentient is focused on securing good partnerships! Nice to see

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL Long-horizon, partial info, shifting incentives… this is where true AI grit shows. MindGames feels like the proving ground we’ve been missing.

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL A lot of reasons for builders to come build and get rewarded. Great collaboration, the future is bright with sentient AGI

@SentientAGI @Princeton @UTAustin @Meta @Radboud_Uni @nyuniversity @MIT_CSAIL The mindgames are on builders time to shine gSenti
