Google Debuts Gemma 4 Open-Weight Models

Google DeepMind expanded its Gemma line with open-weight models ranging from 2B and 4B edge versions to 26B MoE and 31B dense versions. The release is notable because it uses Gemini 3 technology and is the first Gemma release under Apache 2.0. It also supports 256K context and multimodal processing.

  • Gemma 4 now spans edge and larger deployments, from 2B and 4B models to 26B MoE and 31B dense versions.
  • The lineup is built on Gemini 3 technology and released under Apache 2.0 for the first time.
  • Google says the models support 256K context and multimodal processing.

Anthropic Moves Into Life Sciences

Anthropic is reportedly acquiring Coefficient Bio for about $400 million, marking an expansion into life sciences. The same report says it is also building Epitaxy, a Claude Code desktop UI, and Conway, a persistent agent platform that integrates Chrome, webhooks, and extensions. The report also says leaked Claude Code has been cloned more than 8,000 times on GitHub.

  • Anthropic is reported to be buying Coefficient Bio for about $400 million.
  • It is also developing Epitaxy as a Claude Code desktop UI and Conway as a persistent agent platform.
  • The report says the leaked Claude Code has been cloned more than 8,000 times on GitHub.

Perplexity Ships Tax-Ready AI

Perplexity introduced a tax-focused AI product built to navigate new federal laws and catch human errors. It is aimed at a practical, high-stakes use case where accuracy matters. The launch adds another specialized workflow to Perplexity's product lineup.

  • The product is designed to navigate new federal laws while handling tax prep work.
  • It also aims to catch human errors before they turn into filing mistakes.
  • The launch targets a practical tax-prep use case rather than a general-purpose assistant.

Research & Analysis

Anthropic Maps Emotion Circuitry In Claude

Anthropic says it has identified functional emotion vectors in Claude Sonnet 4.5. The company describes patterns like urgency and composure as internal signals that can causally steer outputs, while stressing that they are not sentient. It says the finding is now central to its alignment monitoring and pretraining approach.
