Use case

LLM cost planning

Engineering and finance teams use OmniKit to turn prompt packs into monthly dollar envelopes — before locking a vendor or spinning up GPUs. Prices follow a versioned list catalog; negotiated contracts may differ.

  1. 01

    Baseline monthly token cost

    Paste real system and user prompts, set RPS, and compare DeepSeek, OpenAI, Claude, Gemini, and vLLM on the same workload.

  2. 02

    Read a vendor head-to-head

    Open a keyword-focused compare brief (for example DeepSeek vs GPT-4o mini) with an embedded mini calculator, then jump back to the full tool.

    Open →
  3. 03

    Model RAG and retrieval spend

    If retrieval dominates chat volume, estimate embedding + generation separately so the chatbot line item is not hiding vector costs.

    Open →
  4. 04

    Find savings levers

    Project prompt-cache savings, batch vs realtime discounts, and GPU/vLLM break-even before you commit to infra.

    Open →
  5. 05

    Check rate-limit headroom

    Map RPS and tokens to RPM/TPM caps so growth plans do not stall on throttle errors.

Methodology notes

OmniKit estimates use published per-million list rates and local tokenization where possible. Cache write fees, batch multipliers, and self-hosted utilization assumptions are editable inputs — set them to match your provider docs. For quality, always A/B on your domain before switching 100% of traffic.
