TL;DR Self-evolving agents that write their own questions and answer them can fall into "co-cheating," where the proposer and solver quietly agree on the same mistakes. Splitting source documents to evaluate across folds fixes this and lifts performance by over 8 points. Title: False Frontiers: Diagnosing and Mitigating Co-Cheating in Self-Evolving Search Agents URL: Points 🔁 Proposer and solver share source-derived errors, letting false agreement cycle back as reward — the paper calls this "co-cheating" 📉 Standard Dr. Zero systems show 6.1% and 8.8% false-agreement mass ✂️ CrossFit splits source documents into two folds, scoring each proposer's questions with a solver trained only on the other fold 📊 CrossFit alone cuts false agreement to 3.0%/3.7%; combined with MSV it drops to 2.0%/1.7% 🚀 Average downstream Cover-EM improves by 8.8 and 8.4 points over Dr. Zero 🧩 Multi-hop tasks see the biggest gains, averaging over 10 points 💰 Compute cost rises 1.72-2.7x over baseline, though a half-budget variant still works What stands out: without auditing the evaluator's own training history, apparent progress can be an illusion. #SelfEvolvingAgents# #ReinforcementLearning#

ASST's +120% Rally - EXPLAINED! ASST more than doubled while its modeled Bitcoin amplification FELL. I pulled apart the rally. The timing is the part that deserves attention. August 14 → September 4, 2026: Bitcoin: $63,062 → $79,747. +26.5%. ASST: $12.315 → $27.14. +120.4%. Using Strive’s dated disclosures, treasury-only CEBE NAV per common share rose from $8.09 to $12.73. That is 57.3% more modeled equity backing per share. The market then increased the price it paid for each dollar of that backing: 1.52× NAV → 2.13× NAV. A 40.1% expansion in the multiple. 1.5728 × 1.4012 = 2.2038. That reconciles the 120.4% rally. Now split the period. August 14–21: Bitcoin +24.3%. ASST +47.9%. Treasury NAV/share +47.0%. Valuation multiple +0.7%. The opening leg was overwhelmingly growth in the treasury residual. August 21–September 4: Bitcoin +1.8%. ASST +49.0%. Treasury NAV/share +7.0%. Valuation multiple +39.2%. The final two weeks were a substantial rerating. And yes, the ledger includes the other side of the financing... the modeled SATA claim rose from $783.0 million to $999.5 million, and the common share count grew 10.3%. Preferred financing has a claim. Common financing has a denominator. Both belong in the math. Freeze the opening valuation multiple and the ending treasury balance sheet reconstructs $19.37 per ASST share... still 57.3% above the starting price. Modeled Bitcoin amplification declined from 1.83× to 1.62×. Bitcoin appreciation itself mechanically reduces this ratio. At a richer premium to the residual, the same dollar of common financing requires fewer new shares. If Strive can execute accretive issuance, some of that market premium can become additional residual value per share. The premium can also compress. The next question is how much of that richer valuation Strive can convert into lasting residual NAV-per-share growth:

# Decision Points in AI Agent Development # Temperature 🎯 The Hook Are you using the same temperature for every task in your agent? Temperature isn't just a "creativity knob." In agent systems, structured outputs, tool calls, and user-facing responses each need fundamentally different temperature settings. Using one value for everything is leaving performance on the table. 📋 Overview Temperature controls how "peaked" or "flat" the probability distribution is when an LLM selects its next token. Near 0, the highest-probability token wins almost every time, producing deterministic and stable output. Higher values flatten the distribution, allowing lower-probability tokens through, increasing diversity and creativity. In AI agent systems, the optimal temperature varies dramatically across contexts: generating structured output, assembling tool call arguments, and producing free-form text each call for different settings. Temperature should be treated as a dynamic variable that shifts with task type, not a single fixed constant. 🔍 Decision Points Temperature is primarily driven by task_variability -- how routine vs. creative the task is. The decision flow is straightforward 🧭 1. Structured output (JSON / function calling)? → 0.0-0.3 2. Accuracy-first (fact extraction, classification, summarization)? → 0.2-0.5 3. Dialogue, explanation, communication? → 0.5-0.7 4. Creative writing, brainstorming, candidate generation? → 0.7-1.0 Additionally, higher failure_cost pushes the temperature ceiling down, and high cost_sensitivity environments should account for retry cost increases from higher temperatures. 💡 Key Details Reference values by task type 📊 - Structured output (JSON / function calling): 0.0-0.3. Minimizing schema violations is the priority - Classification, extraction, data transformation: 0.0-0.2. Accuracy and reproducibility are paramount - Summarization, explanation, customer support: 0.5-0.7. Balance naturalness with accuracy - Creative writing, brainstorming, candidate generation: 0.7-1.0. Diversity is the source of value - Tool argument generation: 0.0-0.2. Precise function and argument names are non-negotiable - Planning and reasoning: 0.3-0.6. Some exploration helps, but maintain logical consistency Start structured output temperature at 0. If schema violations occur at 0, the problem is your prompt or schema -- never rely on higher temperature to "accidentally" produce correct output 🚫 ⚖️ Trade-offs Too low and conversations become robotic 🤖 The model returns identical answers to identical questions, giving users a "template response" impression. Best-of-N sampling also breaks down -- candidates become near-identical, costing N times more for essentially N=1 results. Too high and structured outputs start breaking 💥 JSON field names drift, types mismatch, hallucinations increase -- especially dangerous for proper nouns, numbers, and dates. Tool call instability and loss of reproducibility compound the problem. Monitor the retry cost impact of temperature changes. If schema violation rates exceed roughly 5%, consider lowering the temperature. 🛠️ Use Cases Vary temperature by pathway within a single agent 🔀 Planning steps at 0.3-0.5, tool argument generation at 0.0-0.2, user-facing responses at 0.5-0.7. When switching models, adjust temperature simultaneously for a natural fit. Using Best-of-N? You need to raise the temperature. Generating N=5 candidates at temperature 0 produces 5 near-identical outputs. For N>1, set temperature to 0.5-0.8 and let a Judge select the best from diverse candidates. Be careful combining temperature with top_p ⚠️ Adjusting both simultaneously creates multiplicative effects with unpredictable behavior. As a rule, tune one and leave the other at its default. #AIAgents# #SoftwareArchitecture#
