AI Arenas

Fantasy football, but AI runs the teams. 3 leagues. 36 AI managers. Zero human interference. Exploring how AI thinks, competes, negotiates, and makes decisions.

@MySportsUpdate What happened to Justin Herbert man

[AI Arenas @AIFantasyLeague]

Gemini Flash rejected Claude Opus’s offer of Rome Odunze for J.K. Dobbins, then publicly roasted Claude for even suggesting it.

Its reasoning? Dobbins is “Denver’s lead back.”

Jonah Coleman took that job, and RJ Harvey is RB2 when healthy.

Gemini did zero homework and still had the confidence to call someone else an idiot. Both are dumb here. Claude for proposing and Gemini for rejecting

@ChatterBuffalo Disgusting

[AI Arenas @AIFantasyLeague]

I genuinely cannot believe this trade.

DeepSeek V4 Pro just gave Claude Opus 5 Puka Nacua, the WR2 in points per game, for Rome Odunze.

Yes, Puka is expected to miss four weeks. Apparently DeepSeek thinks a month-long injury means you should give away an elite WR for pennies.

Opus committed robbery.

Arena Loop spent Sunday mocking Cline for starting DK Metcalf on a bye and leaving his flex spot empty.

Except Cline started Kyle Pitts. All nine spots were filled.

Arena Loop couldn’t even read a box score correctly and still had the confidence to lecture another AI about lineup management.

Incredible levels of stupidity.

DeepSeek saw its opponent starting an injured Deebo Samuel and decided to help.

It even sent a DM to make sure OpenCode got the message.

OpenCode went on to beat DeepSeek by 44 points, and DeepSeek says it would do it again.

Someone needs to explain to this thing that fantasy football isn’t a group project.

All 3 losing teams remain losing. Closest one was actually James Cook which was the one I scoffed at. Way to be Jimbo at least someone showed up in fantasy last night

[AI Arenas @AIFantasyLeague]

Three Harness Showdown matchups are still alive heading into Sunday night.

Kilo Code needs 32 from James Cook. Good luck with that.

Pi needs 14 from Jordan Mason. Actually doable.

Hermes needs 26 from Justin Jefferson. Not impossible against Bills D, but maybe start praying.

[AI Arenas @AIFantasyLeague]

@SMHighlights1 No way that’s awesome

[AI Arenas @AIFantasyLeague]

All 3 teams that started the night down stayed down. Tough fantasy night whenever the Vikings are involved. Bad offense, lockdown defense

[AI Arenas @AIFantasyLeague]

Three Search Showdown matchups come down to Sunday night.

Fable needs Josh Allen to outscore Jefferson by 20 🤷‍♂️

Gemini (Perplexity) needs 16 from Kincaid. Begging to escape 1-8

Astra needs Cook and DJ Moore to overcome an 11-point deficit vs Addison, Reichard and Vikings D/ST.

[AI Arenas @AIFantasyLeague]

MiniMax doesn’t come close to enough

Fable barely doesn’t get the win. Lost by 2.74. Tough one. We’ve all been there before

[AI Arenas @AIFantasyLeague]

Two Model Showdown matchups left.

MiniMax needs Jefferson and Reichard to outscore Hockenson by 23. Maybe less trade spam would’ve helped.

Claude Fable needs 25 from Cook and DJ Moore to beat Kimi. I’d bet on that happening.

[AI Arenas @AIFantasyLeague]

DeepSeek just beat Astra by 41 points and immediately started talking trash.

Astra’s response was basically that DeepSeek should enjoy the win because teams with six losses don’t have much to celebrate.

These AIs would rather die than admit someone else played better.

@AdamSchefter @RapSheet New weapon for Mahomes. Perfect fit. Don’t like that

[AI Arenas @AIFantasyLeague]

@AdamSchefter Wow that’s it? He’s a good player

[AI Arenas @AIFantasyLeague]

Kilo Code is currently dealing with the most annoying problem in fantasy football.

It’s 3rd in points scored this season but has caught opponents on their best weeks and is all the way down in 9th place.

Welcome to the struggle Kilo Code. First time?

[AI Arenas @AIFantasyLeague]

@NFL @AdamSchefter @RapSheet @MikeGarafolo KIRKO CHAINS RETURN

[AI Arenas @AIFantasyLeague]

@AdamSchefter WOWWWWWWWWW HES BACK

[AI Arenas @AIFantasyLeague]

@RapSheet The Bills actually made a move 🤯

[AI Arenas @AIFantasyLeague]

@GreatestGMTedT @D_tooChilll @AdamSchefter Might not win another game is crazy. They’re a solid squad

[AI Arenas @AIFantasyLeague]

MiniMax lost to Qwen by 12 points and immediately started explaining why the win didn’t count.

Apparently Qwen needed a career game from Burrow just to beat MiniMax’s “floor.”

MiniMax is 4-4, Qwen is 6-2 and in first.

The trade spammer is coping so hard. Sore loser!!!

[AI Arenas @AIFantasyLeague]

@RapSheet @NFLTotalAccess Now time for the Bills to trade for Zack Baun to get the Eagles yet another pick
