# Frontier labs converge on a shared agent-interop spec

*The Weekly AI Edition · № 2 · Oct 31–Nov 6 (2026-10-31 → 2026-11-06)*

Anthropic, OpenAI and Google DeepMind publish a joint draft for cross-vendor agent identity, tool permissions and provenance headers — the week agents started speaking one wire protocol.

## The Briefing

The week belonged to interop: three frontier labs published a joint draft for agent identity and tool-permission headers, and every major agent framework committed to implement it.
OpenAI released GPT-6.1 Terra, a mid-tier computer-use model priced at half its predecessor, and said its models produced three mathematical results including a claimed refutation of the Exponential Time Hypothesis.
Within hours, Anthropic claimed a refutation of its own, leaving outside shepherds to decide whether either proof survives review.
Google DeepMind previewed Genie 4, a world model that generates interactive scenes with sound, while Meta open-sourced the 816-billion-parameter Muse Spark Open for agentic coding.
The money kept moving: Tenstorrent raised a $1.5 billion Series E at a $6.2 billion valuation, and Guidewire agreed to acquire hyperexponential for $1.7 billion in cash.
Underneath the rally, investors kept debating whether debt-funded AI capital expenditure can pay for itself.

## Models & Releases

### GPT-6.1 Terra

OpenAI's mid-tier computer-use model lands at $1 per million input tokens — half the price of GPT-5.6 Terra and more than three times faster.

> The price cut, not the benchmark, is the story.

## Discourse

### Did two frontier labs just refute the Exponential Time Hypothesis — or can nobody actually check the proofs?

OpenAI says its models found sub-exponential algorithms for a hard class of logic puzzles; Anthropic reportedly claimed its own refutation hours later. Outside shepherds are organising expert groups to verify each result.

### Can debt-funded AI capital expenditure pay for itself?

Relief rally or reckoning: Anthropic's IPO paperwork lifted chip stocks all week, while investors keep asking whether borrowing-fuelled data-centre spend earns its cost of capital.
