Anthropic

Direct connection to Anthropic's hosted Claude API. Recommended starter provider — strong tool use, long context, and Anthropic's privacy posture is straightforward.

What you need​

  • An Anthropic Console account: console.anthropic.com
  • A funded workspace (Anthropic gives a small trial credit; production use needs a paid plan or invoice billing)
  • An API key (starts with sk-ant-…)

Steps​

  1. Create the key. In the Anthropic Console: Settings → API Keys → Create Key. Name it something like kenaz-laptop so you can rotate it later without breaking other integrations.
  2. Copy the key. The console shows it once. If you lose it you'll need to create a new one.
  3. Add it to Kenaz. Open the Providers view → Add provider → Anthropic. Paste the key, optionally rename the profile (default: Anthropic), click Test to verify reachability, then Save.

Kenaz will pull the list of models your key has access to. Pick a default — claude-sonnet-4-6 is the right pick for most use; use claude-opus-4-7 when you want maximum reasoning depth and don't mind the latency.

Models and what they're for​

Anthropic publishes the canonical model list at docs.anthropic.com/en/docs/about-claude/models. Rules of thumb:

  • Claude Sonnet — daily driver. Good tool use, good long-context. The right pick unless you have a specific reason.
  • Claude Opus — slower, more expensive, better at multi-step reasoning. Use when you're explicitly trading latency for quality.
  • Claude Haiku — fast and cheap. Good for hooks, batch jobs, or one-shot summaries.

The model picker in the chat header lets you switch per-session — pick Sonnet by default, bump to Opus for the hard ones.

Pricing​

Anthropic's current pricing: anthropic.com/pricing. Kenaz tracks token usage per session in the Usage view, so you can map a session's cost back to the bill.

Privacy posture​

  • Anthropic does not train on data sent through the API by default. Their data policy is at anthropic.com/legal/privacy and the API-specific addendum is at anthropic.com/legal/aup.
  • Kenaz sends prompts directly to api.anthropic.com over TLS. No middleman.
  • If you need a Business Associate Agreement (BAA) for HIPAA, contact Anthropic sales — it's available but not on the self-serve plan.

Troubleshooting​

  • invalid_api_key — the key was revoked or you copied a partial value. Create a new one.
  • rate_limit_error — your workspace is hitting the per-minute limit. Anthropic's rate limits scale with usage tier — see docs.anthropic.com/en/api/rate-limits for the current ladder.
  • Model not available. New models roll out tier-gated; check the model availability table in the Anthropic models doc. Kenaz only shows what your key can call.
  • Long context cut off. The conversation length plus tool definitions plus attachments hit the model's context window. Open the Memory view and compact, or branch to start fresh with the relevant summary.
