Conditional
Multi-agent orchestrator that matches frontier models on key benchmarks by routing across a pool of expert agents — but opaque routing and platform dependency limit transparency.
Is it right for you?
Good for
- Frontier-competitive on SWE-Bench Pro (73.7), LiveCodeBench (93.2), GPQA-D (95.5) — matching Fable 5 and Mythos Preview without training a frontier model
- Multi-agent orchestration through a single OpenAI-compatible API — no SDK migration needed
- Agent pool is swappable — opt out specific models/providers for compliance
- Strong persona stability across long sessions — holds identity where other models drift
- Effective for code review — surfaces significantly more issues than single-model tools
Not good for
- Opaque model routing — you cannot see which underlying models were used for a query
- Not available in EU/EEA at launch (GDPR compliance pending)
- Orchestration can consume 4-6× the tokens of a direct single-model call — hidden cost risk
