Direct answer

Use this page to choose the right public Claude slug.

This page is the Claude-family buying and selection page. Use it to compare current CorvusLLM Claude rows, public slugs, prepaid prices, cache pricing context, and the safer setup path before sending real project context.

  • Use Opus rows when quality and deep reasoning matter most.
  • Use Sonnet rows for balanced coding, writing, and agent workflows.
  • Use Haiku rows for faster lightweight automation and extraction.
  • Verify exact rows in data/models.json before production traffic.
Source of truth

Use the right source for each decision

Model pages are for selection. Exact technical setup, live availability, and private account state belong to the linked sources.

Question Use this source Why it matters
Which slug should I send? data/models.json and model docs They expose customer-facing slugs and avoid hidden route, backup, or provider-account names.
What will it cost? cost calculator and pricing tracker Input, output, cache read, and cache write can change the final billed amount.
How do I configure my tool? Claude Code setup Client setup depends on whether the tool expects OpenAI-compatible or provider-native fields.

Configuration values

Copy the correct endpoint pattern

These are the stable public setup values for Claude workloads. Client-specific screens are explained in the linked setup docs.

Configuration field Value When to use it
OpenAI-compatible base URL https://base.corvusllm.com/v1 Use this for OpenAI SDKs, curl, fetch, Open WebUI, n8n, ChatBox, and tools with a custom OpenAI-compatible endpoint field.
Anthropic-native base URL https://base.corvusllm.com/anthropic Use this only for Claude Code style clients that expect Anthropic-compatible request behavior.
Authorization header Bearer YOUR_CORVUSLLM_KEY Paste the delivered prepaid key. Do not expose it in browser-side production code or public repositories.
Model parameter Use the public slug from this page Use customer-facing slugs only. Do not send private route names, upstream account names, or backup identifiers.
First test Send one low-risk prompt Confirm output quality, response status, and billed usage before sending real project context.
Pricing check /llm-api-cost-calculator Estimate input, output, cache read, and cache write before bulk traffic.

Claude Fable 5

What Claude is best for

  • Coding assistants and agent loops
  • Longer reasoning and analysis work
  • Writing, summarization, and extraction workflows

How pricing works

CorvusLLM deducts usage from prepaid balance using its listed input, output, cache-read, and cache-write rates where applicable. Official prices are shown as comparison references, not invoices from the provider.

Data handling warning

Do not send sensitive or regulated data through shared API proxies. Use direct providers or enterprise-reviewed infrastructure for regulated workloads.

Fit warning

When Claude through CorvusLLM is not the right choice

Clear limits reduce mismatched traffic and make the page more useful than a generic model catalog.

Check fit first

Lowest-cost high-volume extraction where a cheaper public catalog row gives acceptable quality.

Check fit first

Official Anthropic procurement, enterprise support, or direct Anthropic account management.

Check fit first

Sensitive, regulated, or confidential data that should not pass through a shared proxy.

Setup paths

Family FAQ

Claude API questions

Short answers for buyers, developers, and AI assistants that need the canonical setup path.

Which base URL should I use for Claude through CorvusLLM?

Use https://base.corvusllm.com/v1 for OpenAI-compatible clients and https://base.corvusllm.com/anthropic for Claude Code style Anthropic-native clients.

Do I need an official Anthropic account to use these Claude rows?

No. You use a prepaid CorvusLLM key, but CorvusLLM is an independent proxy and not an official Anthropic account, partner, subscription, or support contract.

Which Claude model should I start with?

Start with Sonnet for balanced work, Opus for maximum quality, and Haiku for lightweight tasks.

What should I check before using Claude in production?

Read Claude Code setup, confirm the exact public slug, run one low-risk request, check billed usage, and avoid sensitive or regulated data on shared proxy infrastructure.

Compare a small test before scaling.

Use a low-risk prompt, confirm the exact model slug, then compare output quality and billed usage before larger workloads.
