That comment reads pretty normal to me, and it raises valid points

I wonder what is the business model. It seems like the tool to solve the problem that won't last longer than couple of months and is something that e.g. claude code can and probably will tackle themselves soon.

Why would the problem ever go away? It's compression technologys have existed virtually since the beginning of computing, and one could argue human brains do their own version of compression during sleep.

That's why give the chance to the model to call expand() in case if it needs more context. We know it's counterintuitive, so we will add the benchmarks to the repo soon. Given our observations, the performance depends on the task and the model itself, most visible on long-running tasks

How does the model know it needs more context?

Presumably in much the same way it knows it needs to use to calls for reaching its objective.

Funny enough, Anthropic just went GA with 1m context claude that has supposedly solved the lost-in-the-middle problem.

Just for anyone else who hadn't seen the announcement yet, this Anthropic 1M context is now the same price as the previous 256K context - not the beta where Anthropic charged extra for the 1M window: https://x.com/claudeai/status/2032509548297343196 As for retrieval, the post shows Opus 4.6 at 78.3% needle retrieval success in 1M window (compared with 91.9% in 256K), and Sonnet 4.6 at 65.1% needle retrieval in 1M (co…

Aren't these numbers really bad? > 80% needle retrieval means every fifth memory is akin to a hallucination.

Don't tools like Claude Code sometimes do something like this already? I've seen it start sub-agents for reading files that just return a summarized answer to a question the main agent asked.

I don't think it quite means that - happy to be corrected on this, but I think it's more like what percentage it can still pay attention to. If you only remembered "cat sat mat", that's only 50% of the phrase "the cat sat on the mat", but you've still paid attention to enough of the right things to be able to fully understand and reconstruct the original. 100% would be akin to memorizing & being able to recite in order every single word that someone said during their conversation with you.

But even if I've misunderstood how attention works, the numbers are relative. GPT 5.4 at 1M only achieves 36% needle retrieval. Gemini 3.1 & GPT 5.4 are only getting 80% at even the 128K point, but I think people would still say those models are highly useful.
