The Short Answer

CompletionPrism™ is an AI spend optimization and token cost reduction product from illuminis. It optimizes AI spend by optimizing the work, not the tokens. The unit it manages is the finished task, not the single request. Before each step is sent, it predicts what the task will cost to finish on every model a company has approved, across providers such as Anthropic, OpenAI, Google and xAI, and runs the step on the path with the lowest total cost that still holds quality.

The Costs It Counts

• Token spend across every attempt the work really takes
• Rework, the time a person spends catching and fixing a wrong answer, at their real hourly rate
• Switching, the cached context thrown away when work moves models partway through
• Hidden thinking, reasoning some models bill for and never show
• Context re-read, the whole conversation charged again on every turn

Its Own Agent Harness

CompletionPrism™ runs AI work through its own agent harness: the loop that plans a task, calls the models, uses the tools and checks the result. Because it runs that loop itself, it can choose a different model for each step of the same task. Strong models make the decisions, fast and inexpensive models carry out the routine steps, and long conversations stay with the model already holding them. Before each step it routes down, routes up, stays or stops. Teams that keep Claude Code or Codex can point them at CompletionPrism™ with one environment variable.

What Makes It Different

Most AI cost tools look at the price of each request. CompletionPrism™ looks at the cost to finish the work, which includes every attempt the work takes and the time a person spends fixing a wrong answer. That is why it sometimes routes up to a more expensive model and still costs less overall.

What It Delivers

• The right model, every step, priced as new models ship
• No vendor lock-in, because switching providers becomes a configuration change
• Operational resilience, because work moves to an available model when one goes down
