Fit

Where this model earns its place

code

Code generation and refactoring across large repositories, including multi-file changes.

function calling

Tool use and structured output — dependable JSON for agent loops, RAG pipelines, and workflow automation.

reasoning

Multi-step reasoning — planning, quantitative analysis, and problems that need deliberation rather than recall.

Data handling

Requests are processed in the EU. Prompts are not used for training, and logs follow the retention period in your contract — zero-retention is available on request.

What a month actually costs

Workload	Input tokens	Output tokens	Monthly cost
Prototype	1.0M	250K	$3.50

Illustrative volumes at list price, excluding cached-input discounts and any committed-use agreement. Your invoice shows the same rates, itemised per key.

Cheaper by caching

Repeated prompts — system instructions, retrieved context, few-shot examples — are billed at the cached-input rate where the model supports it. On long system prompts this is typically the largest single line-item saving.

API

Same SDK, different base URL

cURL

curl https://api.itciphtech.com/v1/chat/completions \
  -H "Authorization: Bearer $CIPHER_API_KEY" \

  -d '{
    "model": "mistralai/mistral-large-2407",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

TypeScript
