Agentic Contextor engineering (ACE): Self-improvement in conditions from, not good order

Tl; Dr.: The investigators from Stanford University, Sanuary Systems and UC Berkeley launching Ace Framework improves the performance of the LLM by Planning and increasing the input context Instead of renewing model weights. The essence is treated as a living “bolowbook preserved by three roles-Generator, display, curator-That Delta stuff It is very united to avoid the fall of brevity and the dementia. Reported Profit: + 10.6% In Appworld App Works, + 8.6% In financial consultation, and ~ 86.9% of the average latency vs basics of strong conversion of the context. In Appworld of the former Snapshot (Sept 20, 2025), REAR + ACE (59.4%) ≈ BM CUGA (60.3%, GPT-4.1) While using Deepseek-v3.1.

Which Ace change?

Ace positions of “engineering of the” engineer “as one of the first form of parameter update. Instead of oppressing the instructions into short commands, ace Subscribe and organizes certain domain tactics Over time, arguing that is high The context of the context It also improves the Agentic functions where the tools, the attitude of turning plenty, and the failure of the matter.

Method: Generator → Collector → Curator

• Generator Make functions and generate trajectories (Comment / Tools), useful display vs harmful travel.
• Demonstration reduce concrete lessons from that follow-up.
• The quartered machine on the left Converts lessons into typed Delta stuff (Things of useful / dangerous calculations) and join them by seeing, repeating and dimensions to save the playback aim.

Two designing options-Delta update including Khula-and-christine-Tresevener is a useful history and protects the “fall of context” from monolithic refers. Divide the effects of the context, a group of research team The same llm foundation (deeper thought-v3.1) in all three roles.

Benches

Appworld (agents): Built on a formal basis for response, He's Had, Ace Strong OutperForms (ICL, GPA, Mighty Cheated), with + 10.6% average over the selected foundations and ~ + 7.6% Above Dynamic Cheats at the internet change. Occupile Sept 20, 2025 Foremost Board, REAR + ACE 59.4% vs IBM CGA 60.3% (GPT-4.1); Ace Passes the ciga it is difficult Challenge Break up, while using a small slight source model open.

Finance (Xbrl): On Tact marking tokens and Formula of Xbrl Valuation Thinking, Ace Reports + 8.6% average Above the foundations with the true labels – the fact to adapt to the offline sites; It also works with execution answer, although the quality of the symbols are important.

Cost and Latency

Ace Non-llM MERGES Systemal updates reduces more flexibility:

• Offline (Appworld): -82.3% latency including -75.1% rollouts vs Stress.
• Online (Ferer): -91.5% Latency including -8.6% costs for token vs Dynamic Cheasheet.

Healed Key

• Ace = Formatical Conversion: Improves llms with additional edits “Playbook” (Delta items) chosen by Generator → Cursor → Curator, using every The Base LLM (deep consumption – v3.1) to separate the contextults and prevent fall from monolithic refers.
• Estimated Benefits: Urable + Ace Rabs + 10.6% over the most powerful foundations in Appworld and reaches 59.4% vs IBM Cover 60.3% (GPT-4.1) In September 20, 2025 of the former Snapshot; Financial Reins (Ferer + Xbrl) Show formula + 8.6% average over the foundations.
• Looking up above the re-stationary texts indicating: Ace reduces latency modification with ~ 82-92% and bills / shopping costs is ~ 75-84%Comparison with the Cheatic Cheatic and GEPA's PARETO Prompt Protect Protect Exposer Evolution near.

Store

ACE is a separate engineering as a unique weight of weight: Save persistent booklet, persistent playlists, expressing balanced benefits to Appworld and Finance to remove latency and token the comparative token and rewriting. This approach is a practical conflict, Delta items, and its multiple function – and its limits are clear: The results of the Track Track Republic and quality. If acceptance, agent stains are “adapting” primarily by the appearance of context rather than new look at.
