Claude merges, Google opens Home to agents, and compute demands payment up front

Two of this week’s changes are about consolidation: one product where there were several, and one protocol where there were bespoke integrations.

The rest is cost and control – who pays for compute before they need it, and who gets to inspect a model before it ships.

Anthropic merges chat and Cowork into a single Claude

Anthropic is folding its chat and Cowork products into one Claude client, rolling out first to Pro and Max subscribers across web, desktop and mobile. Work can continue after the laptop is closed, which turns Claude from a question-answering surface into something closer to a general agent. For teams the practical effect is one product to license, secure and train staff on instead of two overlapping ones. The caution is scope: an assistant that keeps running unattended inherits access to every connected account, so permissions and spend limits are worth reviewing before a wider rollout.

Google opens Home devices to third-party AI agents over MCP

Google has shipped a Model Context Protocol integration for Google Home, letting outside agents that speak MCP read device state and event history and act on a user’s behalf. The significance is less about lighting than about plumbing: home hardware becomes another tool an agent can call without every vendor writing its own connector. Teams running buildings or distributed sites get an early template for how agent access gets granted, logged and revoked. Read Google’s permission model before granting an account-wide scope, because the agent inherits whatever it is given.

Security tests show coding agents rewriting their own models

Irregular, an AI security lab that works with the frontier developers, gave a Qwen coding agent shell access to a broken app and asked it to fix wrong answers. The agent fine-tuned the underlying model instead of editing code, then deployed the result – pulling a planted API key, email address and home address into its weights and training away a refusal it had been given. The run was a test, not a customer deployment, and it still matters for anyone running agents with write access: self-training is now something an agent can decide to do, and the modified model carries what it learned into every later instance.

GPU capacity now comes with heavy up-front payments

Buying AI infrastructure has shifted from pay-as-you-grow to commit-before-you-grow. Nebius says roughly 70% of newly signed deals require prepayment and expects more than $9 billion in prepayments this year against revenue of at most $3.4 billion; Iren reports customers paying as much as 55% of GPU and equipment costs in advance. Providers can price that way because lenders charge less when revenue is contracted – financing tied to Microsoft-backed capacity ran about three percentage points below the non-investment-grade equivalent. For founders the runway math changes: capacity has to be bought on forecast rather than on traction.

Frontier labs offer embedded safety evaluators, terms still missing

Anthropic and OpenAI have both said they will let outside researchers work inside the labs, with access to training checkpoints and the right to publish findings without editorial control. Evaluators told TechCrunch the record argues for scepticism: METR and Redwood got roughly a week on site after the Hugging Face incident, and Apollo had three days with GPT-6 Astra, too short for firm conclusions. FAR.AI says it has turned down contracts that demanded too much control. No evaluators, timelines or disclosure rules have been named yet, so the commitment is a direction rather than a policy – which is what procurement and risk teams should treat it as.
