The "infinite context soon" concern comes up a lot — but even at 1M+ tokens, agents still hit limits on long enough tasks, and cost scales linearly with context size.
The compression models are the product, not the proxy. The gateway is open-source because it's the distribution layer. Anthropic, Codex, and others are iterating on this too — but each only for their own agent. We're fully agent-agnostic and solely focused on compression quality, which is itself a hard problem that needs dedicated iteration.
We compress tool outputs at each step, so the cache isn't broken during the run. Once we hit the 85% context-window limit, we preemptively trigger a summarization step and load that when the context-window fills up.
For auto-compact, we do essentially the same Anthropic does, but at 85% filled context window. Then, when the window is 100% filled, we pull this precompaction + append accumulated 15%. This allows to run compaction instantly
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
I'd argue not, as with tool calls it has available to it at all times a description of what each tool can be used for. There's plenty of intermediate but still important information that could be compacted away, and unless there was a logical reason to go looking for it the model doesn't know what it doesn't know.
