Cohere AI has released Rerank 5, a new retrieval model designed to reorder search results for Large Language Models with improved efficiency. The release introduces 'Context Focus,' which identifies relevant passages within documents to reduce token usage by up to 41%, and calibrated relevance scores that function as probabilities rather than arbitrary rankings. This update aims to optimize Retrieval-Augmented Generation (RAG) pipelines by sending fewer, higher-quality tokens to LLMs.

IBM has released Granite Speech 5.0 2B, an open-weight speech-to-text model capable of transcribing and translating audio in six languages under the Apache 2.0 license. The model ranks as the second-best open-source option on the Open ASR Leaderboard with a 5.68% average Word Error Rate for English, utilizing a YaRN extension to support up to 16k positions. It also includes updates to existing Turbo CTC and 4.1 2B Plus models, offering improved speed, keyword biasing capabilities, and robustness against noise.

Perplexity and NVIDIA researchers have introduced JOLT, a new reinforcement learning post-training method that trains a single model to act as both teacher and student. By training the teacher alongside the student using privileged information, JOLT achieves higher accuracy on benchmarks like MATH and AppWorld while requiring 6.5x fewer processed tokens than existing methods like GRPO. This approach addresses the inefficiency of sparse rewards in long agentic tasks by ensuring the teacher's guidance remains consistent with the student's learning trajectory.

Gradium has open-sourced Phonon, a family of small text-to-speech models designed to run entirely on local devices without requiring cloud connectivity or GPUs. The English-only 31M-parameter variant is licensed under Apache 2.0 and fits into a 64.5 MB file, enabling natural speech generation on CPUs, phones, and browsers with minimal latency. Benchmarks show Phonon outperforming competitors like Kokoro in accuracy on difficult text normalization tasks while maintaining real-time performance on standard hardware.

Liquid AI has launched RIPL, a new inference engine designed to serve its Liquid Foundation Models (LFMs) within live request paths with end-to-end latency under 50 ms. The system achieves this by optimizing the full request path and utilizing hybrid model architectures that combine convolutional and attention blocks. Benchmarks indicate RIPL delivers 5.6x to 28.4x lower p95 latency compared to standard vLLM deployments of competing models like Qwen3.5.

Community developers Enigma and Ad Astra have launched the 'Yalu Express,' a new PvPvE campaign server for the Korea IL-2 Series that addresses declining multiplayer activity through dynamic mission design. The server utilizes asymmetrical mechanics where Blue teams push forward while Red teams fight attrition, aiming to sustain engagement across all hours of play. This initiative seeks to revitalize the community by scaling the map based on player counts and eventually simulating the full timeline of the Korean War.

Aerobask has released an officially licensed Dassault Falcon 8X flight simulator for X-Plane 12, marking the first public beta of a purpose-built intercontinental business jet in the platform. The add-on features a custom recreation of the aircraft's fly-by-wire flight control laws and avionics suite, developed with input from real-life Dassault pilots to ensure high fidelity. This release expands the variety of high-end aircraft available for simulation, offering detailed models of the EASy cockpit system and advanced synthetic vision capabilities.

Laminar Research has released X-Plane 12.4.4 Beta 5, introducing significant fixes for graphics, weather synchronization, and VR functionality within the flight simulation environment. Key improvements include resolving flickering night lights, correcting real-world weather recording in replays, and removing a restrictive dataref limit for plugin developers using the SDK. Users opting into this beta build can access these updates via the X-Plane installer, though Laminar warns that instability may still occur.

Fenix Simulations has released a massive V3 update for its Airbus A320 family flight simulator add-on, compatible with both MSFS 2024 and MSFS 2020. The patch introduces extensive improvements to avionics systems, including a new Flight Warning Computer simulation, enhanced VNAV logic, and deeper integration of Navigraph Navdata updates. Additionally, the update addresses numerous bugs related to flight dynamics, display rendering, and system logic to provide a more accurate representation of Thales FMGC and engine performance.

The Muv-Luv franchise received significant updates at its annual livestream, headlined by the upcoming Steam release of Schwarzesmarken in English and other languages. Additional announcements included new content for Muv-Luv Tactics Kalidasa, specific character releases for Muv-Luv Alternative: Total Eclipse, and a productivity-themed spin-off game arriving on Steam later this year. These developments expand the accessible library for fans of the series while introducing new gameplay mechanics and characters.

A BBC investigation reveals that Sudan's Rapid Support Forces (RSF) systematically targeted and destroyed healthcare infrastructure in el-Fasher between May 2024 and October 2025, resulting in numerous attacks on hospitals and the abduction or killing of over 120 medical workers. UN officials have condemned these actions as serious violations of international humanitarian law that may constitute war crimes, while RSF health officials deny the allegations, claiming hospitals were used as military bases. The report details specific incidents where medical staff were forced to operate in makeshift bunkers before facilities were repeatedly shelled or raided.

US President Donald Trump stated that Elon Musk has restored full internet access to Ukraine's Starlink network, ending previous restrictions that hampered Kyiv's armed forces and drone operations. While the White House previously denied ordering these limitations, reports indicate Trump pressured SpaceX to lift speed caps affecting military-grade Starshield connectivity. The restoration follows a period where reduced speeds significantly limited Ukraine's ability to defend against Russian attacks and conduct offensive strikes.

In south-west Yemen, newborn twins Raghad and Raad are fighting for survival amidst a severe acute malnutrition crisis driven by the ongoing civil war between Houthi rebels and government forces. The family was forced to flee their home due to escalating conflict, leaving them unable to afford essential supplies like baby milk while seeking medical care in Aden. Medical staff at al-Sadaqah hospital are struggling with critical shortages of beds, equipment, and funding, resulting in high mortality rates for children displaced by the fighting.

Police in South Africa are investigating the death of a foreign national beaten to death by a crowd of approximately 50 people in Durban. This incident occurs amidst ongoing violent protests against immigrants driven by economic hardship and xenophobia, which have already resulted in deaths in other regions like Cape Town. The government is urging peaceful demonstrations while implementing immigration reforms as diplomatic tensions rise with neighboring countries.

German Chancellor Friedrich Merz warned that the country faces 'intensive' espionage from Russian intelligence services following the arrest of a Ukrainian national suspected of collecting military data on armored vehicles and explosives. This incident is part of a broader trend this year involving multiple arrests of individuals accused of spying for Russia, Ukraine, or other foreign powers, including the recent detention of a former head of Germany's Federal Intelligence Service (BND). The case highlights ongoing security concerns as Germany remains a key supplier of weapons to Ukraine since 2022.
