OpenAI Outlines Playbook for Third-Party AI Model Evaluations

OpenAI has published a comprehensive guide for conducting trustworthy third-party evaluations of frontier AI models, highlighting the importance of rigorous testing frameworks to assess model capabilities and mitigate risks. Released on May 28, 2026, the document offers a detailed playbook for evaluating advanced systems, such as GPT-5.5, in environments where traditional chatbot-style assessments are no longer adequate.　　The guide addresses a growing need for standardized evaluation practices as AI systems become more sophisticated and capable of complex, multi-step tasks. OpenAI underscores that evaluations must go beyond simple question-and-answer setups, advocating for customized “harnesses”—the configurations of tools, prompts, and environments that allow a model to perform a task. These harnesses can significantly affect measured performance, particularly for tasks requiring long-term memory, tool use, or error recovery.　　Three Core Evaluation Areas　　OpenAI identifies three primary claims that evaluations should seek to test:Capability elicitation: Can the model demonstrate the desired ability under optimal conditions？Safeguard performance: How robust are the systems safeguards against misuse or malicious attacks？Comparative performance: How does the model stack up against others under identical conditions？　　To ensure validity, the report emphasizes the need to account for potential distortions such as reward hacking (where models exploit loopholes to achieve high scores), refusals to complete tasks,

XRP And XLM Correlation Sparks Hopes Of A Recovery Surge

XRP and XLM are once again drawing attention as their long-standing price correlation fuels expectations of a potential recovery rally. If history repeats itself, the recent move in XLM could signal that XRP is preparing for a bullish breakout of its own, potentially reigniting confidence across the broader XRP ecosystem.　　Could XLM‘s Breakout Be The Catalyst For XRP’s Next Rally？　　Crypto analyst Bird highlighted a compelling structural possibility for XRP, suggesting that if it mirrors the powerful weekly candle recently delivered by XLM, a rapid ascent above the $2 threshold could be imminent. This move would serve as a vital marker, effectively invalidating the recent bearish trend and signaling a new phase of accelerated growth for the asset.　　Such a breakout would do more than just shift the price; it would fundamentally transform market sentiment. By restoring confidence and generating renewed excitement, this surge would likely flood the XRP ecosystem with fresh capital, confirming that the worst of the recent corrective phase is finally behind us.　　For long-term XRP holders, this momentum would act as a catalyst for heightened activity across the entire ecosystem, driving increased liquidity and participation in memes, NFTs, and Automated Market Makers (AMMs). This surge in engagement across XRP and

Ethereum Flashes A Rare Signal As Open Interest Reaches Highest Level Since 2019

Ethereum is struggling to push above $2,000 as the market prepares for a decisive move that participants on both sides of the trade increasingly recognize as imminent. The price is compressing — and CryptoQuant data has identified a development in the derivatives market that explains why the current level feels like more than a routine resistance test.　　On May 28, Binance recorded a 336,000 ETH increase in 30-day open interest while Ethereum traded near $1,990. That single-venue reading is the highest positive open interest expansion Binance has registered in the current chart since May 2019 — a data point that places the current derivatives activity in a historical context spanning six years of market cycles. This scale of positioning built at this specific price level is not normal market behavior. It is an extreme.　　The expansion was not isolated to Binance. OKX added 106,500 ETH in open interest. Bybit added 34,600 ETH. Deribit added 26,700 ETH. Four major venues simultaneously building derivatives exposure in a compressed window. A combined increase of approximately 503,800 ETH, representing nearly $1 billion in notional positioning, was added in a single session.　　Nearly $1 billion in new derivatives exposure was built around the $2,000 level in a single

Ethereum Price Risks Further Downsides as Leverage Positions Remain Small

For now, Ethereum remains trapped between cautious buyers and traders expecting another move lower. The wider crypto market has also struggled to build momentum in recent weeks, which has added more pressure on large-cap assets like ETH.　　At the same time, many traders appear unwilling to take aggressive positions. That hesitation is becoming more visible in derivatives data, especially in the leveraged market, where activity has slowed sharply compared to earlier periods this year.　　This matters because leverage often plays a major role in sharp crypto price swings. Heavy leverage can fuel fast rallies when prices rise, but it can also increase liquidations during downturns. Right now, the market does not appear crowded with high-risk bets, which changes the way traders are viewing Ethereums next move.　　Ethereum Leveraged Position Analysis　　Crypto analyst CW pointed to the relatively small size of high-leveraged Ethereum positions across the market. According to the latest figures shared online, leveraged long positions currently stand around $1.5 billion, while leveraged short positions sit near $4 billion.　　Even though short positions are larger, the overall scale of leverage remains lower than what traders have seen during major volatility periods in the past. CW explained that this reduces liquidation opportunities for large investors, often

ETH Below $2K: Record Futures OI May Supercharge Volatility

Liquidations, Options, and the Volatility Loop　　The weeks selloff coincided with heavy liquidations across crypto and a sizable options expiry window — two ingredients that can reinforce each other.　　Over a 24-hour span into May 28, roughly $958.8 million in crypto positions were liquidated, with about $897 million being longs, according to CoinDesk. In that same window, CoinDesk reported ETH open interest still rose about 0.61% to 16.39 million ETH. Simultaneously, approximately $8 billion of options notional were set to expire on Deribit around May 29, including roughly $1.4 billion tied to ETH — a near-term gamma event that can amplify realized swings, as noted by CoinDesk.　　How a selloff becomes a cascadePrice breaks a round number (e.g., $2,000), tripping stops and prompting hedges.Perp funding turns, and levered longs face margin calls; forced sells hit thin liquidity.Options dealers adjust delta and gamma hedges into a falling market, selling spot or futures.Downside liquidity gaps widen; more stops and liquidations fire as mark prices slide.Volatility spikes; some shorts cover, others press. The move overshoots until hedging flows subside.　　That loop can run in reverse on sharp squeezes if shorts are crowded. The key is not direction but asymmetry: when leverage is high, small triggers can create

Ethereum Price Structure ‘Weakening’ as Traders Focus on $1.8K Support

Market analysts say Ether (ETH) still faces “downside pressure” that could trigger another ETH price sell-off as traders shift their focus to support at $1,800.　　Key takeaways:Ether faces downside pressure as elevated leverage and positive funding rates amid falling prices signal fragile market conditions.Analysts say ETH must hold the $1,800-$1,750 support zone to avoid a deeper correction.　　Ether price metrics suggest downside risks remain　　Analysts have highlighted several , including an elevated estimated leveraged ratio and positive funding rates amid a “weakening price structure,” according to CryptoQuant analyst PelinayPA.　　The chart below shows that Ethers estimated leverage ratio (yellow line) remains relatively elevated at around 0.74.　　The funding rate (blue line) has remained mostly in positive territory since mid-April, meaning long positions still dominate the market. Meanwhile, the RSI (purple line) is closer to the oversold zone at 31 and has not yet “produced a convincing recovery signal,” the analyst in a Friday QuickTake analysis.　　“Leverage remains elevated and long positioning is still dominant, yet price continues to struggle as the RSI reflects weakening momentum,” the analyst said, adding:　　“Overall this combination suggests that short term downside pressure in the ETH market still remains the dominant structure.”　　Under normal market conditions, rising leverage and increasing funding rates are

NVIDIAs MCG Toolkit Automates AI Model Documentation in Minutes

NVIDIA (NASDAQ: NVDA) has unveiled the Model Card Generator (MCG) Toolkit, a fully automated system designed to streamline AI model documentation. With regulatory frameworks like Californias AB-2013 and the EU AI Act tightening oversight, the toolkit addresses a critical need for auditable, comprehensive documentation—an essential component for deploying AI models at scale.　　Model cards, which outline a model‘s intended use, limitations, and performance, are vital for ensuring transparency and compliance. However, creating these documents manually is time-consuming, error-prone, and often lags behind model releases. NVIDIA’s MCG Toolkit automates the process, generating standardized Model Card++ documents in under a minute from raw source data.　　How It Works　　The MCG Toolkit employs a modular pipeline—Ingestion → Extraction → Rendering—coordinated by a central orchestrator. Users can input data via URLs (from GitHub, GitLab, or HuggingFace) or upload files such as PDFs or Markdown. A REST API is available for programmatic integration.　　In the extraction stage, NVIDIAs proprietary Nemotron RAG pipeline and GPT-OSS-120B model handle high-precision embedding, retrieval, and formatting. The toolkit creates a complete model card, including four subcards (Bias, Explainability, Privacy, and Safety & Security), in a structured JSON format. The final output is rendered into editable Markdown, allowing teams to customize content before publication.　　Performance benchmarks

Bitcoin, ether, XRP, dogecoin lag a nine-week stocks rally as ETF demand cools

The S&P 500s longest weekly winning streak since 2023 and Brent crude settling near $92 on U.S.-Iran ceasefire hopes have failed to pull bitcoin and ether (ETH) higher, with the two largest cryptocurrencies finishing the week down nearly 3% as cooling spot bitcoin ETF inflows reinforced the pullback.　　The S&P 500 posted its ninth consecutive weekly gain on Friday, the longest such run since 2023 and a streak matched only a handful of times in the past four decades, putting the index up almost 20% from its March lows.　　Brent crude settled around $92 a barrel and Treasuries climbed on the week, trimming some of their war-driven losses.　　The macro tailwind has come on hopes the U.S. and Iran will sign off on a 60-day ceasefire extension. President Donald Trump said Friday he was ready to make a “final determination” on a preliminary agreement but restated his demand that any deal require Iran to abandon its nuclear program, surrender its enriched uranium and open the Strait of Hormuz.　　Crypto did not move with the tape. Bitcoin slipped 2.6% over the past seven days to $73,445, ether 2.5% to $2,011, solana (SOL) 2.2% to $82.42 and TRONs TRX 5.6%, its worst weekly drop in the

The Bitcoin ‘Dream Entry’ To Wait For Before The Run-Up To $300,000

A crypto analyst has identified multiple price levels he believes could be dream entry points ahead of Bitcoins (BTC) long-term price rally. The analyst has shared several ambitious price targets for BTC, expecting the cryptocurrency to skyrocket to $300,000 and even $500,000 in the coming years.　　Analyst Identifies Bitcoin Buy Zones Before $300,000 Target　　In a recent X post, market expert Crypto Patel stated that while many investors are panicking after Bitcoins recent decline below $74,000, he is using the opportunity to quietly build his position. The analyst said he is preparing to buy more BTC, suggesting that additional dip buying opportunities may still lie ahead as he targets a long-term rally above $300,000.　　Crypto Patel has identified three ideal Bitcoin accumulation zones ahead of this projected move. The zones are based on Fibonacci retracement levels highlighted on his accompanying chart. The analyst noted that the first entry point around $60,000 has already been filled, leaving just two ideal points remaining. He noted that this first zone aligns with the 0.382 retracement level and a bullish order block.　　Crypto Patel also identified a second accumulation zone near $45,000, which aligns with the 0.5 Fibonacci retracement level. He noted that he is patiently waiting for
