Gateway
Models & providers
26 models you can ask for today across 9 providers, out of 45 keys in the registry — the other 19 are previous-generation keys kept so older configurations still price. Generated from the registry the router and the meter both read, so it cannot drift from what the Gateway actually serves.
A Lobstack model key is what you send as model. It maps to a provider, a provider-native model id, a capability tier and a price per million tokens. The same registry answers three questions: which model the router may pick, which id goes on the wire, and what the tokens cost.
Prices are list prices in USD per million tokens, used for metering rather than for invoicing. Every one of them was last checked against the provider's own pricing page on 2026-09-08. Prices in this category move often; check again before you quote one.
Current generation
These are the 26 keys a picker should offer first, and the pool the router draws from for auto.

Previous generation
These 19 keys are kept so stored configurations keep resolving. Where a provider retired a model outright, the key survives and points at the documented successor — and it is priced at the successor's rate, because a retired model now served by a cheaper engine must not keep billing at the old one.
5 of them redirect today: Grok 3 → Grok 4.3; Grok 4.1 Fast → Grok 4.3; DeepSeek R1 → V4 Pro; DeepSeek V3 → V4 Flash; Llama 3.3 70B → GPT-OSS 120B.

Unverified prices
4 keys are marked with an asterisk above: deepseek-v4-pro, deepseek-v4-flash, deepseek-r1, deepseek-v3. DeepSeek publishes list prices in CNY and its English pricing page has been serving the wrong document, so these USD figures are inherited from the previous catalog and could not be re-confirmed on 2026-09-08.
They are not currency-converted, because DeepSeek's USD prices have historically not tracked a straight FX conversion, and inventing a rate would produce a number that looks checked and is not. The flag is carried in the registry as priceUnverified and surfaced here rather than hidden: a figure we cannot source is not one you should have to take on faith. Metering still uses these numbers, so cost reported for a DeepSeek request is an estimate against an unconfirmed list price.
What is not here
Anthropic Mythos
Mythos exists and it sits above Fable, and it is deliberately absent from this catalog. It ships through trusted-access programmes and is not generally available on the API. Listing it would advertise a model no customer of ours can call.
Groq's Llama models
Groq no longer publishes a public price for its Llama models, so a Llama request can no longer be metered honestly. Rather than delete the key and break stored configurations, the llama-3.3-70b key survives and points at openai/gpt-oss-120b, the Groq-hosted model that does have a published price. A request naming Llama is served by GPT-OSS 120B and priced as GPT-OSS 120B. x-lobstack-model reports the key you asked for, so read the label in this table to know what actually ran.
Aliases
The resolver accepts a set of non-canonical spellings that turn up in stored configurations: provider-native ids, hyphenated variants, and models listed before this catalog existed. gemini-2-5-pro resolves to gemini-2.5-pro; gpt-4o-mini resolves to gpt-5-mini; kimi-k2 resolves to kimi-k3.
Aliases matter for billing, not just for routing. An unresolved key prices at zero, which is the most expensive way to be wrong here: a live agent ran on gemini-2-5-pro and every one of its requests metered free. Pricing goes through the same resolver as routing so that cannot happen again. Resolving a key for routing but not for pricing would be worse than not resolving it at all.
Listing models over the API
The listing is OpenAI-shaped with Lobstack fields added, so client.models.list() works. It returns the canonical keys only; aliases resolve on a request but are not enumerated.
managed_key_configured per model so the difference is visible rather than surprising. In BYOK mode routing never leaves your key's own provider.
