GLM 5.3 and GLM 5.3 Flash are now in Crusoe Intelligence Foundry.

Sign up and let these powerful models handle your most difficult software engineering workflows, [6]at a small fraction of the cost of proprietary offers - but with the same serverless, frictionless experience. ➡️ GLM-5.3: Z.ai's flagship open-weights AI model released on August 14, 2026, built specifically for advanced software engineering and autonomous agent tasks. ✅ Achieves open-source SOTA on Terminal Bench 3.0 and Agents' Last Exam ➡️ GLM-5.3-FLASH: MIT licensed with weights already released. Roughly 9x cheaper for workloads that do not need the frontier tier.

ANTHROPIC PREPARES CLAUDE MONEY FOR PERSONAL FINANCE

Claude Money allows users to link their bank accounts and ask Claude about spending, plans, and other financial questions. It appears to be designed to give Claude persistent access to users' financial context, removing the need to manually upload bank statements or transaction exports. The exact account types, data provider, and supported actions remain unknown. Claude already supports third-party personal-finance connectors, and Anthropic has been building finance-specific agents and products for professional users. The launch timeframe remains unknown.

OPENAI BUYS STARTUP DEVELOPING SMARTPHONE CAMERA

OpenAI has quietly bought Glass Imaging, a company developing smartphone cameras that use AI to produce image quality on par with a DSLR camera. The deal values Glass Imaging at over $300 million. OpenAI's plans for the company are unclear, but it has been developing a secretive device with Jony Ive, the former Apple executive who helped design the iPhone. Glass Imaging was founded in 2019 by two former Apple employees who had previously worked on camera technology at the company.

WHAT DOES PACING MEAN?

Dario Amodei called for the AI industry to self-regulate its pace, but five camps interpreted "pacing" differently without agreeing on a speed. These camps focus on model interpretability, worker interests, economic growth, geopolitical strategy, and resisting new regulations. A previous attempt to limit AI training compute failed, highlighting the challenge of controlling AI innovation speed.

BAD BENCHMARKS AND EVALS: SENIOR SWE-BENCH, NAPKIN MATH, AND WINTER TIRES

Evals are more about avoiding mistakes than following some particular process. There isn't any step-by-step guide that will work, but there are approaches to experimental design that can teach you how to do better. This post aims to help people become better at benchmarking and evals. It looks at three different kinds of benchmarks: one for baseline numbers for performance 'napkin math' estimates, one set of AI model evals, and one on car tires.

WHO GETS TO DEFINE THE RULES FOR AI?

Aidan Gomez, Cohere CEO, argues against a few dominant Silicon Valley firms setting global AI regulations, drawing parallels to historical monopolies that limited competition under safety pretexts. He proposes a diverse, international, evidence-based framework for AI governance, emphasizing transparency, mandatory testing, and independent assurance mechanisms. Gomez warns that current proposals could entrench market leaders, advocating for more inclusive rule-making to foster competition and trust.

AUGMENTED LAGRANGIAN PREDICTIVE CODING

PC-ALM is a local alternative to backpropagation. It is an extension of standard predictive coding (PC), which uses diffusive coupling between layers. PC-ALM trains residual MLPs up to 1,000 layers, nearly matching backprop's performance despite using only layer-local dynamics. It equips each layer with a feedback control dynamical system that distributes and propagates supervision credit throughout a network.

STEPAUDIO 3 TECHNICAL REPORT

StepAudio 3 Gen uses discrete autoregressive modeling over shared RVQ audio tokens to generate speech, voices, vocals, sound effects, music, and mixed audio within one model. It achieved state-of-the-art results on text-to-speech and voice design while retaining broad general-audio generation capabilities.
