Updates from condense.chat

Weekly notes on what we shipped, what changed, and what we are building next. New posts every Saturday.

condense.chat is a context compression API and drop-in proxy for coding agents, RAG pipelines, and chat products. This blog tracks the work behind it — new releases of our Adeline compaction model, changes to the proxy and the OpenAI and Anthropic SDK routes, benchmark numbers, and field notes from running real workloads at scale. If you're new here, start with the first post, then read the API docs or the FAQ for how it all fits together.

The anatomy of a token bill

Where agents spend money, and how to minmax it. A real coding session, replayed with real models and priced cache-aware, comes in 72% under baseline. The rebuilt engine, the live public harness — bugs included — and the rerun commands are all public.

Introducing Helene 1

Helene 1, our newest compaction model, joins Adeline 1 in the condense family and is generally available today. On CoQA a model answering from its compacted context is more accurate than the same model reading the full, uncompressed transcript, while cutting almost a third of the tokens, ahead of every compressor we measured. And dense now drives Codex and OpenCode alongside Claude Code.

Built for teams. Building for the enterprise.

Organizations are live. One workspace, a shared credit pool, a per member budget, and a spend cap you set. The client installs once and then stays out of your way. Under the hood we have been laying enterprise groundwork: zero data retention, a security pass, and a SOC 2 report landing in about three weeks. We skipped a week to clean up after the hackathon.

30 teams, one weekend, 4 billion tokens

We sponsored basedhack, an invite-only AI hackathon in Vilnius, and handed every team a condense key. The proxy compacted 4B tokens of agent context over the weekend — up to $19k of provider spend the room never paid. Plus: Adeline now runs on our own GPUs, and condense joins the AWS Global Startup Program.

Adeline V1 ships. The API ships with it.

Adeline 1, Our compaction model, goes live today. And the proxy now speaks both the OpenAI and Anthropic SDKs — point your base_url at a provider route, keep your key, change nothing else. Includes the new rewrite mode and the numbers so far.
