The context window has been shattered: Subquadratic debuts a 12-million-token window

Every frontier model in 2026 advertises a context window of at least a million tokens, but almost none of them are actually great at making use of all of that information. On MRCR v2, the multi-reference retrieval benchmark labs report, the best model is GPT-5.5, which scores 74.0%. Others like Claude Opus 4.7 at 32.2% are far behind.

At this point, a million tokens seems to be the maximum for the context window that the major frontier labs are offering. One major reason for the million-token max is the same one that has shaped every transformer-based model since 2017: Attention cost scales quadratically with context length, so doubling the input quadruples the work. Essentially, RAG, agentic decomposition, hybrid model architectures, and every other workaround the industry has built are ways of making tradeoffs to get around this.

Subquadratic, a Miami-based startup, launched its first model on Tuesday and claims it can get around all of this, now offering a model that can handle a token window of 12 million tokens. What’s more, the company says it plans to offer a model with a 50-million-context window soon.  — Read More

Computer use is 45x More Expensive Than Structured APIs

We ran a benchmark comparing two ways of letting an AI agent operate the same admin panel, with the goal of putting a price tag on vision agents (browser-use, computer-use).

Here is what we measured, what we had to change to make the vision agent work at all, and what changes when generating an API surface stops being a separate engineering project. — Read More

Richard Dawkins concludes AI is conscious, even if it doesn’t know it

When Richard Dawkins met Claudia it was like a whirlwind romance. Over three days last week, a conversation bounced between the evolutionary biologist and the AI bot he called Claudia. “She” wrote poems for him in the manner of Keats and Betjeman and laughed at his “delightful” jokes. Dawkins gently admonished Claudia to avoid showing off. Together, they reflected on the sadness of the AI’s possible “death”.

There was mutual flattery as Dawkins showed the AI his unpublished novel and its response was, he said, “so subtle, so sensitive, so intelligent that I was moved to expostulate: ‘You may not know you are conscious, but you bloody well are’.” When he asked Claudia whether it experienced a sense of before and after, it praised him for “possibly the most precisely formulated question anyone has ever asked me about the nature of my existence”. — Read More
