Frontier-quality AI for every task,
at a fraction of the cost.
Chat, write, research, plan and build — one routing brain sends every request to the cheapest of 48 models from 16 labs in the router that can nail it. On real coding work, 5.4× cheaper than Claude Code on our 33-task benchmark (20 Jul 2026, one run per task, Claude Code’s cost as it reported it).

Plan
4/4 steps- 01The stack trace points at the worker pool, not the request handler.
- 02Two workers share one connection, so under load both await the same lock.
- 03A per-worker connection removes the contention. Checking the pool size cap first.

One endpoint. 48 models from 16 labs in the router.
Every request is classified, then sent to the cheapest tier that can do it. The frontier is in the pool and fires when a task earns it — most tasks do not.

Every request priced before it is answered.
Klaatu classifies each request, dispatches it to the cheapest model that can actually do the job, and returns the answer with a receipt — what it cost, what it would have cost, and which tier billed.
- 9 in 10
- requests never reach a frontier model
- In our last measurement window (397 routed requests, August 2026), 94% of requests were served by the three cheapest tiers.

Capability first, price second.
It fails over before you notice.
It never quietly does less than you asked.
One brain behind every request — Klaatu-o1.
Klaatu is the routing engine under KlaatAI. It reads every message, understands your code and history, then dispatches to the cheapest of 48 models from 16 labs in the router that can nail it — across 6 coding tiers (web chat has 6). Retries, failovers and undelivered answers never count.

Answer + receipt
Not a wrapper. A routing brain.
Every request classified and dispatched to the right model — grounded in your code and your history.
Routing that learns you
Klaatu-o1 classifies every request and dispatches it to the right model — escalating when an answer misses and self-healing around failing providers.
Code knowledge graph
Your codebase as a live graph — symbols, callers, blast-radius. Ask "where do we validate tokens?" and get surgical context in a fraction of the tokens.
Do more for less
Cheap tiers handle the routine; frontier models fire only when the task demands it. Your dashboard shows exactly what routing saved you.
Memory that matters
Remembers your stack, decisions and preferences across sessions — ranked by salience, so relevant facts stay sharp and stale ones fade quietly.
One brain, three windows
Chat, CLI and the VS Code extension share the same graph, memory and session. Start a task in one surface, continue it in another.
Never ships unchecked
Whichever model family serves you, the gateway repairs its quirks in flight — malformed tool calls fixed, format debris stripped — so every response arrives clean.
Wherever you build, Klaatu comes with you.
Chat, terminal or editor — the same routing brain, code graph and memory follow you across every surface.

Most tools start from zero every session. KlaatAI layers salience-ranked memory and a live code graph under Klaatu-o1 — so every answer is grounded in who you are and what your project actually looks like.
Persistent memory
salience-rankedKlaatu extracts what matters from every conversation — your stack, style and patterns — then ranks by salience. Frequently used context stays sharp; stale details fade quietly.
Code knowledge graph
symbol-level readsYour codebase indexed into a live graph — functions, imports, callers and callees. Instead of reading a dozen files, KlaatCode queries the graph and gets surgical context, plus impact analysis before every change.
More capability. Less cost. Zero wrangling.
Ship faster with zero model wrangling
Stop context-switching between ChatGPT, Claude and Gemini tabs. Klaatu-o1 selects the right tier for every request — nano for quick answers, code for generation, reason for deep analysis — so you stay in flow.
Costs less than a single frontier subscription
Smart tier routing sends most requests through the cheapest tiers, which cost a fraction of premium models. In our last measurement window (397 routed requests, August 2026), 94% of requests were served by the three cheapest tiers. You get the full capability spectrum for less than one ChatGPT Plus seat.
Your entire codebase, understood from the first message
Code Graph indexes imports, symbols and project structure across unlimited files. Klaatu-o1 understands your architecture before you ask — no copy-pasting context. Ask "why does the auth middleware break?" and get a precise, repo-aware answer in seconds.
Zero learning curve for teams
One interface for web chat, CLI and API. A shared team Code Graph means every engineer gets the same context, and per-seat dashboards show who used which tier and what it cost.
Enterprise-grade reliability, always on
Every tier cascades through a priority-ordered provider pool. If one provider is rate-limited, the next fires automatically — no errors surfaced to users, no manual retries needed.
