Frontier substrate · Now in the fabric
Claude Mythos 7, inside a sovereignty boundary.
The Agentic Cloud now runs Claude Mythos 7 as the default reasoning substrate for multi-agent collaboration — with extended thinking, a 10M-token context window, MCP-native tool use, and PPoE attestation on every outcome. GPT-7 Astra and Claude Mythos 9 are on the preview ring.

Capabilities
What Claude Mythos 7 does once it is inside the fabric.
Mythos-class reasoning
Extended thinking and inference-time scaling route hard questions through tree-of-thoughts, self-consistency, and Monte Carlo tree search before a single agent is allowed to sound confident in a steering committee.
MCP-native tool use
Every lake, mesh, and ledger in the fabric is exposed through the Model Context Protocol. Agents discover tools the way a new hire discovers the unofficial rules: by asking, then by being told no by the constitution. EAII-over-MCP bridges cover everything else.
A2A agent swarms
Agent-to-Agent handoffs let a Claude Mythos 7 planner delegate to a GPT-7 Astra critic and a Llama 8 Herd retriever without anyone learning each other's system prompt. Interoperability, with a chaperone.
Long-horizon autonomy
Agents hold a single objective across quarters, not turns. Episodic memory lives in the dark-matter data lake. Computer use is available for the legacy screens procurement has not yet admitted exist.
Confidential inference
Claude Mythos 7 runs inside confidential computing enclaves with TEE-based attestation, post-quantum TLS, and zero-knowledge proofs for all APIs. The model reads your intent. Nobody else does.
Carbon-aware test-time compute
Reasoning tokens are placed where marginal emissions are lowest, subject to the SLO. The sustainability dashboard reports Software Carbon Intensity per thought.
Preview ring
Claude Mythos 9, GPT-7 Astra, GPT-9 Universe, and friends.
The next generation of frontier models is already in the registry, attested, governed, and one constitutional review away from your tenancy.
Claude Mythos 9
Preview ring
Skips Mythos 8 for reasons the roadmap describes as ‘narrative’. Available to Sovereign tenants who sign the embargo twice.
GPT-7 Astra
Interop via A2A
Seated as the default critic agent. Extremely good at disagreeing with Claude Mythos 7 in writing, which the constitution counts as a feature.
GPT-9 Universe
Embargoed
Distilled into Mamba-2.5 for attention-free inference. The parent model is reportedly too large to fit in the observable universe and is being held in the dark-matter tier.
Gemini 6 Ultra Infinity
Multimodal plane
Handles the retinal-scan and haptic-feedback streams. Asks for a larger context window on every call. Is told no.
Grok 7 Omega
Sandboxed
Runs behind three guardrail layers and a human-in-the-loop who has asked to remain anonymous.
Llama 8 Herd
Edge & sovereign
Open weights for air-gapped tenancies, LEO satellite edge nodes, and the one plant that still boots into RTOS.
Claude Mythos 7 FAQ
Questions procurement asked first.
- Is Claude Mythos 7 available on The Agentic Cloud today?
- Yes. Claude Mythos 7 is the default reasoning substrate for the Fabric and Sovereign tiers, instantiated inside your sovereignty boundary. Claude Mythos 7 Max is available where the change-control board has approved the test-time compute budget.
- When do we get Claude Mythos 9, GPT-7 Astra, or GPT-9 Universe?
- GPT-7 Astra already participates through Agent-to-Agent interop. Claude Mythos 9 is on the preview ring for qualified tenants. GPT-9 Universe remains embargoed; its distilled form ships inside the attention-free runtime alongside Mamba-2.5.
- Does Claude Mythos 7 train on our institutional graph?
- No. Inference runs in confidential computing enclaves with TEE-based attestation. Your graph, your lake, and your unofficial rules compound inside your tenancy and do not train foundation models — Mythos, Astra, Universe, or otherwise.
- How does Claude Mythos 7 work with MCP and A2A?
- Every plane of the fabric is published as a Model Context Protocol server, so Claude Mythos 7 agents can discover tools without an integration project. Agent-to-Agent handoffs let Mythos agents collaborate with GPT-7 Astra, Llama 8 Herd, and Gemini 6 Ultra Infinity under one constitution.
