LLM cost calculator to a monthly budget
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.
- 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.
Open → - 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 → - 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 → - 04
Find savings levers
Project prompt-cache savings, batch vs realtime discounts, and GPU/vLLM break-even before you commit to infra.
Open → - 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.
Start at the LLM Cost Calculator. For vendor-access risk after acquisitions, read OpenAI vs Cursor & annual AI SaaS. For DeepSeek peak/off-peak and vision limits, read DeepSeek V4 pricing & scaling. For a first-party note on a free high-volume preview model, see What is Ox Alpha?; for the Z.ai identification and serving-stack story, read GLM-5.3-Flash inference economics; for Alibaba's open-weight MoE direction, see Qwen3.8-Flash-Next / Qwen4.

Frequently asked questions
How do I plan LLM cost before I scale?
Baseline monthly token cost from real prompts and traffic, compare vendors on the same workload, then model RAG, cache, batch, and rate-limit headroom before you commit infra.
Which OmniKit tools belong in an LLM cost plan?
Start with the LLM Cost Calculator, then RAG Cost Estimator, Prompt Cache Savings, Batch vs Realtime, GPU/vLLM TCO, and Rate-Limit Planner. Use /compare briefs for vendor head-to-heads.
Where can I read DeepSeek API pricing details?
See OmniKit’s DeepSeek V4 architecture, vision, pricing, and scaling guide, then verify numbers in the live LLM Cost Calculator catalog.
