Frontier AI, with the meter showing
Watch what it can do.
Watch it pay for it.
A self-updating, data-backed living showcase of frontier AI capability. The chat is the proof. The glossary is the spine. Capability without consciousness, demystified.
Demo loop. The wired chat lands next.
Three things this site is
A demo, a glossary, and an honest meter.
Talk to it
Hit the chat. Watch the response stream in. See input tokens, output tokens, and cost increment in real time. Every turn ships you a receipt.

Tokens. Cache reads. Stop reasons. Hallucination versus confabulation. The glossary turns every metric on the screen into a teaching moment.

The corner pill shows today's research budget in real time. Hard cap. No surprises. The site refuses to hide what it costs to run.

The vocabulary of frontier AI.
Tokens
tokens
Tokens are the units a language model reads and writes. Roughly four characters of English per token, give or take. Every cost and every limit on this site is d...
Context window
context-window
The context window is the maximum amount of text, in tokens, that a model can consider in a single request. Everything you send in plus everything the model wri...
Prompt caching

Prompt caching is a feature that lets the model store a static prefix of your prompt (system instructions, retrieved documents, conversation history) and re-rea...
Cache read
cache-read
Cache read tokens are input tokens that were served from the prompt cache rather than processed fresh. They are billed at roughly 10 percent of normal input pri...
Cache creation
cache-creation
Cache creation tokens are input tokens that were written to the prompt cache for reuse on later turns. They cost slightly more than normal input on the way in (...
Stop reason
stop-reason
The stop_reason field in an API response tells you why the model stopped generating. Common values: `end_turn` (the model decided it was done), `max_tokens` (it...
Lab Notes
What's being built, in the open.
The site is the demo, including the construction site itself. Every shipped milestone, every cap tuning, every cost lesson goes here.
Schema, models, glossary seed
14 tables migrated, 14 Eloquent models, glossary seeder + 10 seed terms covering side-rail metadata and editorial-spine concepts.
Public design pass: brand palette, typing hero, traced cards, token meter
Brand parity with kevinchamplin.com. Pexels imagery on every glossary term. Five wow moves landed.
Hero chat, wired
Livewire 3 + Reverb streaming to App\Showcase\Claude\Client, every call gated by App\Budget\Gate. The demo above goes from canned to live.
