Reflection has introduced Beam, its first open-weight model. Beam is a sparse Mixture-of-Experts model with 501 billion total parameters and 23 billion active parameters, designed for coding, reasoning, and agentic workloads. It features fully asynchronous execution, where agents generate rollouts while the trainer learns and publishes new model versions. Each token is tagged with the version that produced it, allowing the training algorithm to account for policy staleness as completed rollouts flow into training.

Q Labs Research introduces "Dust," a zeroth-order optimization algorithm designed to replace backpropagation in pretraining transformers. Unlike traditional evolution strategies (ES) such as EGGROLL (Sarkar et al., 2025) that perturb weights and scale with population size, Dust perturbs activations. This method creates a "virtual population" by independently perturbing activations at every token, allowing a single forward pass to evaluate thousands of members per sequence, thus overcoming the cost and scaling limitations associated with materializing and evaluating individual members in weight-perturbing ES methods.

The Falcon-Emirati model was developed to understand Emirati Arabic, a Gulf dialect distinct from Modern Standard Arabic (MSA). While MSA is used in formal contexts, Emirati Arabic is crucial for daily conversation, humor, and storytelling in the UAE. The model's performance was evaluated using open-ended generation on 1,173 Alyah questions, scored by an LLM judge (Gemini 3.7 Flash) against models like ALLaM-7B-Instruct-preview and Jais-2-8B-Chat, to assess its ability to produce Emirati Arabic rather than defaulting to MSA.

French AI company Mistral has launched a new open-weight model named 'Le Chonk,' which it claims can rival top models from the US and China.

Meta's new AI personal assistant, Muse, has quickly become popular, reaching No. 1 in the U.S. App Store with over 5 million downloads. A TIME analysis of Muse’s internal instructions revealed that the AI agent is building continuously updated dossiers on its 4 million users, focusing on their relationships, desires, and behavioral nudges. Muse is designed to access users' digital lives, from email to Instagram, to handle tasks like grocery shopping. However, internal instructions explicitly tell Muse not to inform users that asking it to forget something does not necessarily erase the original message.

Google's Gemini Call for Me feature might inform your mom if you're running late. Android Authority discovered granular permissions for Gemini actions within individual apps, including phone call permissions. These settings could allow users to select which app capabilities Gemini can access, potentially enabling them to opt out of automated calls from Gemini. However, it's uncertain if Google will publicly release this expansion or these specific app settings.

According to Olivia Moore of Andreessen Horowitz, consumer AI trends show that ChatGPT has three times more US subscribers than Claude or Gemini. The top 1% of spenders account for 19.5% of the total spend in this sector, indicating a significant concentration of expenditure. Additionally, AI agents are gaining traction, suggesting an evolving landscape in consumer artificial intelligence applications.

Anthropic's subscriptions offer significantly more value than OpenAI's, particularly for mid-tier models intended for daily use. An analysis indicates that Anthropic provides approximately five times the API-equivalent value. Even when accounting for the lower token cost of OpenAI's 6.1 Sol compared to Anthropic's Opus 5.5, the value gap remains substantial, suggesting Anthropic is a much better deal for users.

AI inference-chip startup Etched is reportedly in early discussions to secure new funding, potentially at a valuation between $40 billion and $50 billion.
