## Anthropic adds message threads beta so Claude agents stop resending whole chats

Tools. Long agent sessions on the Claude API can send only new turns, and Anthropic reports about 35% faster first responses at 500k to 1M tokens. Prices are unchanged, and threads are not eligible for zero data retention.

## Anthropic open-sources FlashProve to prove which model produced an answer

Security. The research prototype uses zero-knowledge proofs so anyone can check on an ordinary CPU that a reply came from committed weights, without seeing them. Buyers using models through resellers or routers could one day verify they got the model they paid for.

## EU court adviser says chatbot answers from news articles may breach publishers' rights

Policy. In the first generative AI case at the EU's top court, Advocate General Szpunar says training is generally allowed, but real-time retrieval that reproduces an article's wording can infringe. The opinion is not binding. Anyone building on retrieval should watch the final ruling.

## Hume AI launches API that answers plain-language questions about raw audio

## OpenAI publishes LifeVal, a benchmark of everyday tasks for personal AI agents

Agents. It measures agents on chores such as childcare searches, budgets and government services, built from time-use studies and a 3,995-person survey. The scores come from OpenAI itself, so they show direction rather than independent proof.

## Salesforce agrees to buy voice-agent firm Cresta for Service Cloud

Communication. Cresta's voice agents handle full customer calls and coach human staff for brands such as Marriott and Comcast. Voice service moves inside the CRM, so contact centres face a bigger platform decision. Closing is expected in Salesforce's fiscal Q1 2028.

## Sarvam releases Prism, an open decision model for English and 10 Indian languages

Language. Prism returns calibrated probabilities for yes/no, choice and score questions in 44 ms instead of generating text, at ₹4 per 1M input tokens. Teams routing, triaging or moderating multilingual traffic get a cheap judge they can tune and run themselves.
