Halowerk · LLM Catalog

modell.halowerk.com

A comparison table of language models: input, output and cache prices per million tokens, context window, maximum output length, batch discount and a short note on what each is suited to. Filter by vendor, by a maximum price, by the context window you need, or by capability tag. Every row carries the date its prices were last checked, so a stale figure is visible rather than silently wrong.

Halowerk · EV Charging

karte.halowerk.com

Queries OpenStreetMap for charging stations within a radius of a point and returns each with its position, distance, operator, network, connector types with their individual power ratings and socket counts, access restrictions, fee status, opening hours and whether authentication is required. Results are sorted nearest first and can be filtered to a minimum power or a required connector type, which is the question a vehicle actually has.

Halowerk · Inverter Load Check

solar.halowerk.com

Continuous load is the sum of the running watts of all appliances marked as simultaneous. The surge check adds the largest single starting surge on top of the continuous load, which is the case that trips an inverter; simultaneous starts of two motors are reported separately as a second figure. Starting factors and power factors are design rules of thumb per appliance class and are stated in the response, they are not device data.
