Fable 5 is dead. We just resurrected it — cheaper, open and you hold the keys.

OpenRouter dropped Fusion 48h ago and broke the internet.

We tested it hard. The synthesizer is insane for deep research… but absolute dogshit for coding. So we fixed it.

Meet http://OrcaRouter.ai DSL — the version you actually own. One prompt → fans out to any panel you want → judge + synthesizer → one god-tier answer.

But unlike black-box slugs, you control the entire graph in YAML.

Fable 5 level intelligence… without waiting for Anthropic to turn it back on

OrcaRouter — One AI gateway: adaptive LLM routing & governance

Source: https://www.orcarouter.ai/ OrcaRouterOne gateway · every model · all your AI traffic

One Gateway. Every Model.Route Smarter. Ship Safer. Spend Less.

OrcaRouter grades every prompt and routes it intelligently. Frontier-quality AI at up to 40% lower cost. Adaptive routing, load balancing, guardrails, agent firewall, observability, and governance — all through a single OpenAI-compatible endpoint.

One line. We grade each prompt, route to frontier or OSS, and add $0.

AI gateway for production

Smart routing and automatic failover on every request.

Routing that’s measurably more accurate.

Every prompt is embedded and routed by a model that keeps learning online from real traffic. On the public RouterArena leaderboard (Jun 2026) it leads on accuracy — ahead of GPT-5, Azure, Martian and NotDiamond — at 75.5%.

* Based on RouterArena leaderboard data, June 2026.

A provider goes down. No one notices.

When a provider rate-limits or 5xxs, OrcaRouter retries the request against a healthy model across 200+ options before the response starts — so transient upstream outages don’t surface to your users.

200+ modelsauto-failoverno 429

See and prove every call — cost, model, latency, and why.

See everything. Prove anything.

See exactly what every request cost, which model served it, how long it took, and why it failed — full structured logs you can filter, replay, and copy as a runnable cURL. A route is never a black box.

Per-request logsgrade · model · costcopy-as-cURL

Zero markup. Zero black boxes.

You pay each provider their exact price — we add $0 per token, ever. Every request shows the grade, chosen model, provider, latency, and price, so cost is glass-box, not an opaque blended rate.

$0 / tokenprovider costglass-box receipt

Versioned prompts and caching — without a redeploy.

Change prompts. Not code.

Version prompts behind named labels with A/B splits and one-click rollback. Move a label and every request picks it up instantly — no redeploy, no code change, no client update.

VersionedA/BInstant rollbackNo deploy

Pay once. Reuse for free.

Repeated and cached prompt tokens bill at the provider’s cache rate — often a fraction of the input price — across 5-minute and 1-hour ephemeral windows. Same answers, less spend, with cached_tokens on every receipt.

Guardrails, budgets, and an agent firewall that enforces.

Guardrails that stop things.

PII Shield and content policies run before the upstream call is billed. A blocked request returns a clean 400 and is never charged — guardrails enforced inline, not logged after the fact.

PII Shieldenforced pre-billingclean 400

Safe for your team. And your agents.

Budgets and roles for people; a risk-scored firewall for agents. Every tool and MCP call is graded ALLOW, REVIEW, or BLOCK before it runs, and anomaly detection flags rate and cost spikes against learned hour-of-week baselines.

You ship, on one endpoint

Traffic goes direct to each provider’s first-party API at their published rate — we add $0 per token. One OpenAI-compatible endpoint for routing, observability and governance.

Every model. One price list.

200+ models with live, side-by-side pricing — what you’d pay the provider directly. We add $0 on top.
