How to Use Claude Opus 5 Free (No Credit Card)

Updated October 2026 · 3 min read

Claude Opus 5 is one of the most capable AI models available — but official access is expensive. The good news: a provider called CodeCraft offers 1 million free tokens per month with no credit card required, and you can chat with it through NovaMind's free interface.

Honest note: CodeCraft is a third-party API provider, not affiliated with Anthropic. Their "Claude Opus 5" label is their own model offering served through an OpenAI-compatible API. Treat it as a capable model in its own right rather than assuming it's identical to Anthropic's official model.

Step 1 — Get your free CodeCraft key

Go to codecraftapi.com and create a free account.
Generate an API key (it starts with cc_).
Your free tier includes 1M tokens/month — no card asked.

Step 2 — Open NovaMind

Go to NovaMind AI.
Select the CodeCraft provider button.
Paste your cc_ key and press Enter.

Step 3 — Chat

That's it. Ask anything — writing, coding, analysis, translation. Your key stays on your device: NovaMind never sees or stores it. Close the page and it's gone.
