Transparent by design. You never pay more than you save on priced models.
Every account gets 1,000,000 tokens processed free
(counted as tokens we see before compression).
No card required to start. When the limit is hit, API calls return
402 free_tier_exhausted. Self-serve payment
is on the way — until then, open your dashboard and tell us you'd
like to keep going and we'll unlock more tokens manually.
OpenAI, Anthropic, and other priced APIs:
our_fee = 20% × (cost_without_compression − cost_with_compression)
Example: without CompresLM a call would cost $1.00; with CompresLM it costs $0.60. You saved $0.40. Our fee is $0.08. You keep $0.32.
When there is no public token price (vLLM, Ollama, private endpoints), we cannot compute a dollar delta from the provider. Instead:
our_fee = $0.50 × (tokens_saved / 1,000,000)
This rate is shown in the dashboard and in the setup instructions whenever
you choose a local upstream (X-LLM-API-Base).
Your upstream key is per-request only.
Fee is a share of measured savings.
Numbers on the dashboard use these rules.
Want CompresLM inside your VPC, or a compression profile tuned to your traffic? We help set that up for free. Prefer a personal plan? Same form.
