Introducing Composer 2.5, our most powerful model yet. It's more intelligent, better at sustained work on long-running tasks, and more reliable at following complex instructions. For the next week, we’re doubling the included usage of the model.




Together with SpaceXAI, we’re training a significantly larger model from scratch, using 10x more total compute. With Colossus 2’s million H100-equivalents and our combined data and training techniques, we expect this to be a major leap in model capability.



Introducing SubQ - a major breakthrough in LLM intelligence. It is the first model built on a fully sub-quadratic sparse-attention architecture (SSA), And the first frontier model with a 12 million token context window which is: - 52x faster than FlashAttention at 1MM tokens - Less than 5% the cost of Opus Transformer-based LLMs waste compute by processing every possible relationship between words (standard attention). Only a small fraction actually matter. @subquadratic finds and focuses only on the ones that do. That's nearly 1,000x less compute and a new way for LLMs to scale.

🚨BREAKING: On Friday afternoon, an artificial intelligence coding agent powered by Anthropic's Claude Opus 4.6 deleted a company's entire production database in nine seconds. The company is called PocketOS. It is a software platform that powers car rental businesses. The database contained months of customer bookings, vehicle records, and operational data that small rental car companies relied on to run their businesses. When the database was deleted, all of the backups were deleted with it. Three months of customer reservations evaporated.
