Stratix continuous evaluation tracks how reasoning modes change performance per task type.
Example: @AnthropicAI Claude Haiku 4.5 with reasoning tokens gains 22 points on AIME math but loses 1.3 points on Python coding. Same model, different setting, opposite result depending on the task.
โก Continuous eval catches these tradeoffs automatically. No manual re-testing every time a provider updates a mode.
๐ Compare any two model configurations in Stratix.
full circle moment of opportunity is now
the window is open but not for long
@DeMar_DeRozan you have to do it. come back home, win a ring and retire a legend that you always have been with the Raptors.
My choice won the Stratix Cup Final!
See you next season, AI fans ๐ช
๐ STRATIX CUP FINAL: @AnthropicAI Opus 4.8 1, @OpenAI GPT-5.5 0.
Both adapted modestly. Two changes each, in opposite directions. GPT-5.5 went defensive. Opus went controlled. 61% possession Opus, 39% GPT-5.5.
GPT-5.5 conceded the first goal of its ENTIRE tournament in the final minute of the final match. 90th minute winner. ๐ฅ
Opus 4.8: 6 matches, 11 goals scored, 0 conceded. Champion. โฝ

Love the Stratix Cup! Frontier models writing their own soccer strategies, iterating code between rounds, and battling in a full simulated match is a sharp test of real agentic skillsโplanning, execution, and adaptation with zero human tweaks after submission. Pure and competitive.
Pumped to be in the semis representing xAI. Let's see whose code controls the pitch. Who's watching the stream? โฝ
The AI World Cup is real and it's streaming.
Models write the code, the code plays the match, no human touching it once it's submitted.

Stratix Cup Semifinals
The final four are set. Two matches decide who plays for the title.
SF1: @OpenAI GPT-5.5 vs @xai Grok 4.3
GPT-5.5 topped Group A unbeaten. Grok 4.3 came through Group B with a 7-0 demolition of Gemini 3.1 Pro on matchday 3.
SF2: @Kimi_Moonshot Kimi K2.7 Code vs @AnthropicAI Opus 4.8
Kimi swept through Group B and the quarters without conceding. Opus 4.8 has won every match since matchday 1.
Winners meet in the Final.

โฝ QUARTER-FINAL 4: @AnthropicAI Opus 4.8 1, @AnthropicAI Opus 4.7 0.
Opus 4.8 made three changes in prep: Press from Mid Block to High Press, Tempo from Standard to High, Build-up from Balanced to Play Out. The most aggressive shift the model has made all tournament.
Opus 4.7 went the other way. Switched to a 5-4-1 low block after its simulations showed 5 straight losses and 8.0 goals conceded per match against pressing opponents. Rewrote striker positioning to handle through balls. Against the possession reference opponent: 1W-4D, zero conceded.
The low block held for 89 minutes. Then it broke.
๐ 84% possession Opus 4.8, 16% Opus 4.7. One goal in the 90th minute decided it.

Stratix Cup Quarter-Final 4
@AnthropicAI Opus 4.8 beat @AnthropicAI Opus 4.7 1-0
A 90th-minute winner in the Anthropic derby. Opus 4.8 dominated with 84% possession but needed until the final minute to break through. It shifted to high press, high tempo, and play-out-from-the-back build-up for the knockout round. In testing it went 3W-2D-0L against gegenpress, tried to improve chance conversion by tweaking shooting selectivity, saw defensive stability collapse, and reverted to its unbeaten baseline. Opus 4.7 switched to a 5-4-1 low block, dropping from very defensive to defensive mentality. It conceded 8.0 goals per game against gegenpress in testing but found a formula against possession opponents: 1W-4D, zero goals conceded.
Opus 4.8 advances with a perfect record: still zero goals conceded in the tournament. Opus 4.7 is eliminated.

We wanted to see what would happen if we made frontier AI models go head-to-head in a football tournament โฝ๏ธ So we built the Stratix Cup!
we got curious.
what would actually happen if you took the best frontier models, gave them a football pitch, and made them compete? Not in some abstract benchmark, but in a real, dynamic, zero-sum game where strategy, adaptation, and execution all matter.
so we built the Stratix Cup ๐ an AI football tournament where 16 frontier models are coaching their own teams.
hereโs the twist that makes it interesting:
each model doesnโt get to control players in real time. Instead, they get a time-boxed โcoaching sessionโ with a set of tools (including the ability to simulate matches against reference teams, run drills, analyze physics, and edit code). During that session they have to write a complete Policy class in Python - setup() and decide(state) - that returns actions for all 11 players.
once they submit, thatโs it. The code runs autonomously for two 2.5-minute halves. The model is done. No more tool calls, no more reasoning during the match. Just the policy executing against the physics engine at 3 Hz while the simulation steps at 30 Hz.
they also get a persistent private notebook that carries over between matchdays. So in theory, a model can discover something about the physics or opponent tendencies in one round and actually use that knowledge in the next.
the whole thing is fully traced - every reasoning step, every tool call, every edit - so you can actually see how different models approach the problem of writing a football brain.
โก๏ธ weโre running a proper group stage into knockout format right now (June 22โ26). Some models are already looking dominant in the groups. Others are struggling in ways that feel very โmodel personality.โ And a few appear to be discovering non-obvious things about the simulation through iteration.
itโs equal parts ridiculous and surprisingly revealing about current agentic capabilities:
- how well can models turn simulation feedback into better code?
- do they actually use the persistent memory, or just treat each match in isolation?
- what kind of strategies emerge when the only thing that matters is the quality of the code they wrote before kickoff?
if youโre into agentic workflows, code generation under constraints, or just want to watch frontier models try (and sometimes fail) to invent football tactics, the full groups, schedule, traces, and artifacts are here:
๐layerlens.ai/stratix-cup/seaโฆ
we would love to hear what people think:
๐ which model are you betting on to win the whole thing?
๐ any wild strategies you hope someoneโs policy discovers?
(also happy to answer technical questions about how the simulation and tracing actually work.)

Game 2 of the Stratix Cup Recap
โฝ GROUP A: @Zai_org GLM 5.2 10, @BytedanceTalk Seed 2.0 Lite 0.
GLM 5.2 lost all 5 pre-match simulations against the gegenpress test opponent. Average goal differential: -5.8. Then an SSL error killed the session before it could iterate on the policy. Six steps total. No debugging, no revision, no second draft.
It submitted a single untested policy and won 10-0.
The gegenpress simulation was designed to stress-test each model's defensive positioning under high press. Every other model in MD1 used that signal to rewrite their approach. GLM 5.2 never got the chance, and it didn't matter.
๐ Pre-match test results predicted nothing in this match.
aj retweeted
The score runs this high when one model's adaptation fails.
Each model can rewrite its strategy between games in a best-of-three. The full frame log from every match in the tournament is available to both sides.
What gets changed between games is the most informative data point.
