Real recording
Claude Opus 5.5 was selected for a one-line request. OptiFlume switched the model under the composer to GPT-5.2 before the prompt went out.
From model selection to conversation memory and agent safeguards, OptiFlume handles the decisions behind your AI workflow so you can focus on the work itself.
Token optimizer
The right model and effort for every prompt. Routine work goes to a lighter model, hard problems to the strongest one, so no tokens are burned on the wrong model. Every switch shows where you work, with a one-line reason.
Prices span about 100x from the lightest model to the strongest.
Context management & collaboration
Compactions and model switches stop wiping the slate. Goals, decisions, constraints and the approaches that already failed carry over, so the next model picks up where you left off.
Coming next: start a session in one tool and pick it up in another.
Safety, security and focus
Keys, tokens, personal details, card numbers and bank details are kept out of what the model reads. Destructive commands are warned about or blocked before they run. Loops and sessions losing track are called out. Every intervention is logged on your machine.
Free on every plan.
Learns how you work
It reads the code a task touches and how the session is going, not only your words. Every time you overrule a pick, it learns how you judge difficulty, so its choices drift toward yours.
On Pro. Your style stays on your machine.
Most of what you ask an AI coding tool to do is routine: rename this, write that test, commit. Sending those to a frontier model burns your allowance on work a lighter model does just as well.
Two hours in, the chat compacts and the model starts again from a summary: goals blurred, failed fixes tried again. Your context should outlast the conversation.
Agents read files and run commands on their own. One wrong command, or one key read into a chat, is all it takes. You shouldn't have to check every line to feel safe.
The same fix, failing the same way, for the fourth time. It is hard to see from inside the loop. OptiFlume notices, and gives you the evening back.
In long agent sessions, most of the bill, often more than 80%, goes to carrying context: writing the conversation to the cache and reading it back, turn after turn. Model choice is the visible cost. Context is the one nobody is managing.
One install answers all five.
See how it worksIndependent by design
Model providers, and the tools that resell their models, earn more when you use more tokens. That is their business. Advice on using fewer should come from someone who earns nothing from them. OptiFlume charges one flat price and takes no cut of your spend, so every call it makes is in your favor.

Available to individuals
Your console shows your own usage, on Pro and during the trial: what ran, what OptiFlume switched or suggested, and, in Cursor, the spend it avoided against the model you had selected, across every Mac on your account. Counts only; never your prompts or code. Turn it off with one command.

How OptiFlume handled them
The questions engineers ask before installing, answered the way we would answer them in person.
All questions →Cursor, Claude Code and Codex, in their VS Code panels and in the terminal, with more tools on the way. It is on as soon as you install, and one license covers every tool on every Mac you sign in on.
Not always. Good code comes from good context as much as from an expensive model. OptiFlume judges how complex each task is and sends it to the model it needs: hard work to the strongest model, routine work to a faster one. After your tool compacts a long conversation, the next model gets a short working memory of your goals and decisions (Pro), so it starts with the context it needs. When it is unsure, nothing changes.
No. Everything OptiFlume reads and decides happens on your machine, and OptiFlume never sends your prompts or code anywhere. (Cursor, Claude Code and Codex still send your prompt to the model you use, as they always have.) The routing engine works offline.
It fails open. If any part of OptiFlume errors, your prompt goes through unchanged on the model you selected. It cannot lock you out of your editor. Uninstall is one command.
Team-wide visibility into what drives the invoice and per-project routing policy across Cursor, Claude Code and Codex, with the decision still made on each engineer's machine. Early access is open.
