weckr-model-pricing

weckr-model-pricing is a skill for Claude Code from Ghiles3232/weckr-sdks. It costs 100 tokens per session (1,749 once invoked), scanned A, original, MIT.

A reference for current per-token API prices for large language models from OpenAI, Anthropic, Gemini, and Kimi. It lists input, output, and available cached-input rates in US dollars per million tokens.

In plain words
What is it for?
Use it to compare model prices, find a cheaper model for a task, or estimate the cost of a request from its input and output token counts.
Why use it?
It avoids manually checking and comparing provider pricing when estimating model costs. Provider prices change, so billing decisions still require checking the provider’s current pricing page.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

weckr-model-pricing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Weckr model pricing

A maintained reference of per-token API prices for the models Weckr supports. Prices are US dollars per million tokens, split into input (prompt) and output (completion), with a cached-input rate where the provider offers prompt caching. This mirrors the price table shipped in the Weckr SDK (@weckr/sdk), so it matches what Weckr uses to recompute cost server side.

Provider prices change often. Treat this as a fast reference, not a contract: for anything you bill on, confirm the live number at the provider's pricing page. Verification dates are noted per provider below.

When to use this skill

Use it when a user wants a price, not an integration. For example:

  • What does gpt-5.4-mini cost per token, or per thousand calls.
  • Which model is cheapest for a summarization or classification job.
  • Compare Claude Opus 4.8 against Sonnet 4.6, or Gemini against Kimi, on price.
  • Roughly what a prompt of N input tokens and M output tokens will cost.

If the user wants to project the cost of a specific feature per user, or wants continuous per user cost tracking in production, that is the weckr-cost-estimator and weckr-integration skills, not this one.

Get the live numbers first

For the current prices, fetch the canonical Weckr price feed and read from it:

https://useweckr.com/pricing.json

It is JSON, generated from the same table Weckr uses to recompute cost, so it is always current. Shape: models["gpt-5.4-mini"] = { provider, input, output, cachedInput, cacheWrite? }, prices in USD per million tokens, plus a lastVerified date per provider. If the fetch is unavailable, fall back to the table below, which is a dated snapshot and may have drifted.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
