02 / MODEL CATALOGUE
Know the model.
Trust the source.
Our goal: authentic model access, clearly identified models, and quality you can evaluate. Starting with Claude, with Fable 5.1 and Opus 5.5 in the planned lineup.
Fable 5.1
claude-fable-5-1A headline model in our planned Claude offering.

claude-opus-5-5A second featured option for your development workflow.
Provider verification pendingOur launch standard: verified model identities and transparent routing. Accuracy claims will be backed by evaluations—not assumed from a model name.

03 / SIMPLE RECHARGES
Start at $15.
Keep the ideas coming.
See how many API calls your budget could cover. Start small, experiment, and add more when you need it.
$15TO GET GOING
About 2,160 calls to get started.
Estimate your API calls using our original package ratio: $50 for approximately 7,200 calls.
Estimated API requests, not full conversations. Actual totals vary by model, message length, and output. One chat can use several calls.

All purchases are simulated. Package call counts and token thresholds are reference estimates, not guaranteed allowances. The demo enforces dollar balances; actual consumption depends on model rates and request size. Final live rates await provider integration.
04 / GOOD TO KNOW
Frequently asked
questions.
Is PromptCore only for Claude?
We’re starting with Claude. PromptCore is being built for multiple model providers, with a single usage balance. Other providers are not available yet.
How much will I save?
Affordable model access is the goal. Final model rates and savings comparisons will be published after provider costs are confirmed, using equivalent models and workloads.
Can I use this for live API requests today?
Not yet. The console is a working local demo with simulated requests and balances. Upstream API access, streaming, and verified model routing will be connected in the next integration phase.
Do I need to convert dollars into credits?
No. A $15 recharge adds $15 to your usage balance. Model usage is deducted in dollars, so your spending stays easy to follow.
Are the package token numbers guaranteed?
No. They are reference figures from the proposed packages. The current demo bills against a dollar balance using illustrative per-model rates, rather than a fixed token allowance.
Will this work with Claude Code and my apps?
That is the planned integration. Compatibility must be implemented and tested with the chosen upstream provider before live access is offered. The demo does not currently forward API requests.
Will the demo charge my card?
No. There is no payment integration. Recharges and package purchases only add simulated local balances.
Is this an official Anthropic service?
No. This is an independent service prototype, not affiliated with or endorsed by Anthropic.
