Hermes 4 on OpenGradient
Hermes 4 405B, no datacenter required.
Nous Research's Hermes 4 is the reference steerable, uncensored open model - and the 405B flagship is far past home-GPU territory. OpenGradient serves it (and the faster 70B) in the chat picker: plain answers, full instruction-following, behind the anonymity layer. It's the model our anonymous guest chat runs on.

The usual way has a catch
Running Hermes 4 yourself is a hardware problem.
Hermes 4 is open-weights - which traditionally means either serious GPU hardware at home or a developer API with keys and payloads. The steerability is the point; the setup is the tax.
Local means limits
Consumer GPUs cap you at small quantized variants; the flagship sizes need datacenter hardware. Cloud APIs solve compute and reintroduce accounts, keys and logs.
Identity rides along
Hosted access normally attaches your account to every prompt. The anonymity layer here splits identity from content - structurally, not by policy.

Here's how OpenGradient is different
The open flagship, served properly
Flagship sizes, no hardware
The full-size models - not the quantized compromises - served from the studio picker alongside every other family, switchable mid-conversation.
Steerable and uncensored
Neutrally-aligned open models that follow instructions instead of moralizing - no jailbreak prompts, no permission dance, within the published content policy.
Anonymous by architecture
Encrypted relays and secure enclaves ensure no party - including us - holds both your identity and your prompts.

Questions, answered
Frequently asked
- What is Hermes 4 best at?
- Instruction-following without the moralizing: Hermes is neutrally aligned, deeply steerable via system prompts, and strong at reasoning for an open model. The 405B is the quality pick; the 70B answers faster and cheaper.
- What does it cost?
- Pay per message from a credit balance - the per-model rate is shown in the picker. Free messages to start, packs from $10, no subscription.
- Is this list current?
- Yes - the model chips above render from the live catalog at build time, so the page always matches the picker.
