BREAKING: The blackout in Spain and Portugal in April 2025 did NOT happen because of renewables. The final ENTSO-E report on last year's Iberian blackout is out — and it's essential reading for anyone working on the energy transition. entsoe.eu/news/2026/03/2…

Cursor is raising at a $50 billion valuation on the claim that its “in-house models generate more code than almost any other LLMs in the world.” Less than 24 hours after launching Composer 2, a developer found the model ID in the API response: kimi-k2p5-rl-0317-s515-fast. That’s Moonshot AI’s Kimi K2.5 with reinforcement learning appended. A developer named Fynn was testing Cursor’s OpenAI-compatible base URL when the identifier leaked through the response headers. Moonshot’s head of pretraining, Yulun Du, confirmed on X that the tokenizer is identical to Kimi’s and questioned Cursor’s license compliance. Two other Moonshot employees posted confirmations. All three posts have since been deleted. This is the second time. When Cursor launched Composer 1 in October 2025, users across multiple countries reported the model spontaneously switching its inner monologue to Chinese mid-session. Kenneth Auchenberg, a partner at Alley Corp, posted a screenshot calling it a smoking gun. KR-Asia and 36Kr confirmed both Cursor and Windsurf were running fine-tuned Chinese open-weight models underneath. Cursor never disclosed what Composer 1 was built on. They shipped Composer 1.5 in February and moved on. The pattern: take a Chinese open-weight model, run RL on coding tasks, ship it as a proprietary breakthrough, publish a cost-performance chart comparing yourself against Opus 4.6 and GPT-5.4 without disclosing that your base model was free, then raise another round. That chart from the Composer 2 announcement deserves its own paragraph. Cursor plotted Composer 2 against frontier models on a price-vs-quality axis to argue they’d hit a superior tradeoff. What the chart doesn’t show is that Anthropic and OpenAI trained their models from scratch. Cursor took an open-weight model that Moonshot spent hundreds of millions developing, ran RL on top, and presented the output as evidence of in-house research. That’s margin arbitrage on someone else’s R&D dressed up as a benchmark slide. The license makes this more than an attribution oversight. Kimi K2.5 ships under a Modified MIT License with one clause designed for exactly this scenario: if your product exceeds $20 million in monthly revenue, you must prominently display “Kimi K2.5” on the user interface. Cursor’s ARR crossed $2 billion in February. That’s roughly $167 million per month, 8x the threshold. The clause covers derivative works explicitly. Cursor is valued at $29.3 billion and raising at $50 billion. Moonshot’s last reported valuation was $4.3 billion. The company worth 12x more took the smaller company’s model and shipped it as proprietary technology to justify a valuation built on the frontier lab narrative. Three Composer releases in five months. Composer 1 caught speaking Chinese. Composer 2 caught with a Kimi model ID in the API. A P0 incident this year. And a benchmark chart that compares an RL fine-tune against models requiring billions in training compute without disclosing the base was free. The question for investors in the $50 billion round: what exactly are you buying? A VS Code fork with strong distribution, or a frontier research lab? The model ID in the API answers that. If Moonshot doesn’t enforce this license against a company generating $2 billion annually from a derivative of their model, the attribution clause becomes decoration for every future open-weight release. Every AI lab watching this is running the same math: why open-source your model if companies with better distribution can strip attribution, call it proprietary, and raise at 12x your valuation? kimi-k2p5-rl-0317-s515-fast is the most expensive model ID leak in the history of AI licensing.

Jordan - The EV Guy@JordanEVGuy·
Fact check: Spain blackout claim 1. “Wind and solar triggered the collapse.” ❌ Misleading / unsupported Investigations did not conclude that renewables caused the blackout. European grid authorities and analysts have repeatedly said the outage was not caused by renewable generation itself.  Officials and energy analysts stated the electricity mix (including high solar output) was typical and had been handled safely many times before.  The Spanish government and EU officials explicitly rejected claims that renewables caused the outage.  ⸻ 2. “Spain lost 2.5 GW in the first 80 seconds.” ⚠️ Partially true, but distorted There was a sudden loss of generation early in the event. Investigations identified roughly 2.2 GW lost within about 20 seconds after failures in substations in Granada, Seville and Badajoz.  However: •The cause of that generation loss was not confirmed to be wind or solar. •It originated from grid infrastructure failures, not specifically renewable plants. ⸻ 3. “Every MW of that loss came from renewables.” ❌ No credible evidence This claim appears widely in social media posts, but official reports have not confirmed that all lost generation was renewable. Investigators said the exact sources of the lost generation were still being analysed.  ⸻ 4. “Gas and hydro remained stable until the cascade.” ⚠️ Unproven claim Reports do not state that fossil or hydro plants “remained stable.” The cascade involved: •multiple grid disconnections •substation failures •interconnector trips with France  So the narrative that “only renewables failed” is not supported by the investigation. ⸻ 5. “Spain’s grid had virtually no inertia.” ⚠️ Partially true but oversimplified Some analyses suggested low synchronous generation (gas, nuclear, hydro) may have reduced system stability. A technical study concluded the blackout involved: •insufficient synchronous generation •voltage instability •weak transmission resilience  That is a grid management issue, not simply “renewables failed.” ⸻ 6. “Europe is hiding the truth.” ❌ Conspiracy framing The investigation is still ongoing. The final ENTSO-E report is expected in 2026, and early reports deliberately avoid premature conclusions.  That’s normal for large grid incidents. ⸻ What actually happened (best current explanation) The blackout was likely caused by a cascade of grid failures triggered by voltage instability, starting with substation failures in southern Spain which led to a rapid loss of generation and disconnection of interconnectors.  Key contributing factors being studied include: •Voltage surge / overvoltage •Grid protection systems disconnecting equipment •Insufficient synchronous generation online •Weak transmission margins •Possible renewable-heavy conditions interacting with grid design But no official investigation has concluded “wind and solar caused it.” ⸻ ✅ Bottom line The post is classic energy-misinformation framing: •Uses real numbers (2.2–2.5 GW loss) •Attributes them to renewables without proof •Adds conspiracy language about Europe hiding the truth.

NOBODY KNOWS HOW FUCKED THE SITUATION IN THE PERSIAN GULF ACTUALLY IS. 3,200 ships are TRAPPED in the Persian Gulf right now. Crews are running out of drinking water. One ship called the local port authority and BEGGED for permission to dock — just to get water. They were DENIED. 💀 Let that sink in. These aren't military ships. These are commercial vessels — carrying oil, grain, electronics — with civilian crews who are now stranded with NO supplies and NO way out. – 3,200 ships STUCK ⚠️ – Crews running out of WATER 💀 – Port authorities REFUSING to let them dock ⚠️ – Multiple ships reporting the SAME situation 💀 ⚠️ For context — the Suez Canal crisis in 2021 blocked 400 ships. This is EIGHT TIMES worse. And nobody is talking about it. They're showing you missile interceptions and oil price charts. They're NOT showing you thousands of crew members slowly running out of drinking water in the middle of a war zone. If these ships start getting abandoned, the environmental disaster alone would be catastrophic. Thousands of tons of fuel, cargo, chemicals — just sitting there. This is not a shipping disruption. This is a HUMANITARIAN CRISIS unfolding in real time. Prepare accordingly. 🚨🚨🚨 X is hiding this. Follow + RT before it disappears. 🔥

¡Terrorífico ese comunismo! ¡Va a destruir al sector productivo! Pero resulta que el decreto no es sino la aplicación y reglamentación de los acuerdos con la OIT (Convenios 98 y 154 de la Organización Internacional del Trabajo) que Colombia firmó y aprobó hace décadas (Ley 27 de 1976 para el Convenio 98 y Ley 524 de 1999 para el Convenio 154). Por cierto, este miedoso comunismo es lo que se aplica en Europa desde hace largo tiempo. La OIT lo considera una buena práctica. ¿Está Europa en ruinas? Creo que están un poquito mejor que nosotros. Pero la candidata Valencia lo presenta todo desde el miedo, porque el miedo es lo único que tiene: el miedo a los trabajadores organizados, como buena representante de los ricos y poderosos. Cada avance de los trabajadores en Colombia siempre ha sido presentado por la clase de Valencia como un paso más hacia el precipicio, o incluso como un apocalipsis infernal. No le crean. Vivan los trabajadores.
Paloma Valencia L@PalomaValenciaL

#ATENCIÓN. El Gobierno sacó un Decreto que prácticamente le entrega el manejo de las empresas a los sindicatos. Van a tener acceso a toda la información financiera de la compañía y a los secretos empresariales. Ademas, todos los trabajadores deberán pagar la cuota sindical, sin importar si están afiliados o no, y las empresas quedarán cobijadas por acuerdos sindicales por sectores. Esto va a acabar con el sector productivo. Los sindicatos se van a apoderar de las empresas. Acá les cuento los detalles de este peligroso Decreto:

Gustavo Petro@petrogustavo·
Mi gobierno no es autoritario, respetamos las decisiones de los jueces y no les intervenimos sus comunicaciones ni los perseguimos. Que diferencia del gobierno dónde asesinaban a miles de jóvenes solo para hacer una errónea política de seguridad del estado.
Paloma Valencia L@PalomaValenciaL

El único adversario que tenemos en esta democracia es la continuidad del gobierno Petro, por sus ínfulas autoritarias y su estrategia de erosionar progresivamente las instituciones hasta acabar con el equilibrio de poderes, mientras le endulza al oído a los colombianos con promesas incumplidas.

Un lamentable paso atrás de privacidad en Meta. Abandonan y desactivan el cifrado de extremo a extremo en los mensajes directos de Instagram. Sería bueno explicar a todo el mundo que las conversaciones privadas por Instagram no son seguras ni realmente privadas.

IMF lecturing China about “hurting the global economy” is peak comedy. This is the same IMF that applauded Western deindustrialization for decades, the same IMF that justified US tariff wars, the same IMF that ignored the devastation caused by Washington’s monetary tightening on emerging markets. But now China’s competitiveness — built on infrastructure, productivity, and innovation rather than colonial extraction — is framed as a global danger. The US and EU have poured hundreds of billions into subsidies, tariffs, export controls, and protectionism — from the IRA to the CHIPS Act to Europe’s state-aid binge. But China’s industrial policy is the problem? The only reason the global economy didn’t collapse under Trump’s two trade wars was because China acted as the stabilizing counterweight to US volatility. It wasn’t China that shattered global supply chains. It wasn’t China that launched unilateral tariffs. It wasn’t China that weaponized the dollar and turned trade into geopolitical blackmail. China kept markets supplied, prices stable, and manufacturing running, which is exactly why they’re now calling it “harmful.” Because China’s efficiency exposes Western inefficiency. Because China’s manufacturing scale exposes Western dependency. Because China’s stability exposes Western volatility. When the West subsidizes, it’s “strategic.” When the West destroys trade, it’s “protecting democracy.” But when China competes — efficiently, peacefully, and through open trade, suddenly it becomes “a threat to the global economy.” The double standard is the real subsidy here.
