Pricing

Nehemvix is free. You bring your own AI model key and pay only your AI provider, at their prices.

Why it is free: Nehemvix is AELSHA™'s working demonstration of how it engineers AI agents, and the company's paid work is agentic AI consulting for teams taking agents to production.

What a guide costs

The cost depends on the size of the repository and the model you choose. Before anything is spent, Nehemvix shows the likely, low and high cost, and you approve it. Your spending limit is a hard stop.

Spend less

• Files already summarised are reused, so a second guide for the same repository costs less.
• Prompt caching is used where your provider supports it.
• Smaller, cheaper models work well for small repositories; choose a larger one for complex systems.

If you run agents of your own, we also wrote about where an agent's tokens go and how to cut them.

Free tiers

Many providers offer free tiers or credits. Nehemvix respects your provider's rate limits and pauses safely if a limit is reached, so you can resume later or switch models without losing work.

Two ways to make a guide for $0: Google Gemini's free tier (set it up), and OpenRouter's free models, whose ids end in :free. Nehemvix shows a free model's price as $0, from OpenRouter's own list, and keeps to OpenRouter's free limits (free models on OpenRouter). Free tiers may keep or use what you send, so read the provider's terms before you send private code.
