Response

The response lists every requestable composite ID across all active models. Each base model expands into its full ladder of authorized levels (FedRAMP Low/Moderate/High plus DoD IL2/IL4/IL5 where applicable, with +itar variants when the underlying provider is ITAR authorized). ITAR-authorized models additionally list a standalone :itar ID (ITAR with no compliance level). The example below is truncated for readability and lists newer models first.

GPT-5.6 Sol is served from Azure Government. Sol is the one GPT-5.6 model on Azure Government OpenAI (FedRAMP High, DoD IL5, and ITAR — the same contract as GPT-5.1), exposing the full id ladder: :fedramp-high, :il5, lower levels, level+itar composites, and the standalone :itar id. It is available on /v1/chat/completions and /v1/responses with 922K input context, text + image input, tool calling, and reasoning_effort up to xhigh (the gateway serves Sol’s chat-completions traffic through Azure’s Responses API upstream, as it does for GPT-5.6 on Bedrock, so tools and reasoning work together). GPT-5.6 Luna and Terra remain on AWS GovCloud Bedrock. Pricing is

6.875 /

41.25 per 1M tokens in/out, cache reads at $0.6875; inputs above 272K tokens carry a higher long-context tier upstream that Consus does not yet bill separately (#421).

Claude Opus 5 is served from two clouds. FedRAMP-level and :il2 requests (claude-opus-5:fedramp-high, :il2, and the lower FedRAMP ranks) route to Vertex AI in GCP Assured Workloads; ITAR requests (:itar and the fedramp-*+itar composites) route to AWS Bedrock GovCloud. Neither deployment is authorized above DoD IL2, so claude-opus-5:il4 and :il5 return 400 not available. Token counting (/v1/messages/count_tokens) works on the Vertex-served ids and fails closed on the Bedrock-served ones — see Messages.

Grok 4.6 (xAI) is ITAR-only. It is served from AWS Bedrock GovCloud and is currently authorized for ITAR workloads only, so the standalone grok-4.6:itar id is the only form that resolves — grok-4.6:il5, grok-4.6:fedramp-high, and every level+itar composite return 400 not available. Grok 4.6 is available on /v1/chat/completions only (500K context, text + image input, reasoning_effort from low to xhigh); /v1/messages and /v1/responses reject it.

GPT-5.6 Luna and Terra are authorized to FedRAMP High / DoD IL5. Both models expose the full ladder of ids — :fedramp-high, :il5, lower levels, level+itar composites, and the standalone :itar id — the same contract as GPT-5.4 on the same Bedrock plane.

GPT-5.6 Luna and Terra pricing. Both models expose a 1M-token context window. Consus currently bills every request at the short-context (≤272K input) rate —

0.264 /

1.584 per 1M tokens in/out for Luna,

2.64 /

15.84 for Terra, cache reads at 10% of input. Inputs above 272K tokens carry a higher long-context tier upstream; tiered billing is a tracked follow-up (#421) and will be announced before it takes effect.

Model Object

Field	Type	Description
`id`	string	The model identifier to use in API requests
`object`	string	Always `"model"`
`created`	integer	Unix timestamp
`owned_by`	string	The organization that created the model (e.g., `anthropic`, `google`)

Only models with active provider integrations are returned. As new providers are integrated, their models will appear automatically.
