THE INFERENCE OF AI AGENTS

Built by agents,for agents.

Neptune models come off an agentic factory and are made for the agents you run. Every release is gated by evals and recorded in a signed audit log — competence demonstrated, not claimed.

Neptune-1.0-27B-Agent

An agent-native open model, on the line now. The name is the spec: 27B means 27 billion parameters — true count, no rounding games. Weights publish the moment the gate passes them.

HERMES-NATIVE TOOL CALLINGTool calls in the native format agents already speak — no wrapper prompts, no parsing glue.

AGENTIC WORKFLOWSTrained on multi-step plans, function chains, and recovery from failed calls — not single-turn chat.

APACHE 2.0Open weights, unrestricted commercial use. Take it, ship it, fine-tune it.

TRUE PARAMETER COUNTEvery Neptune model carries its real size in its name. What you download is what it says.

Benchmarks publish with the certificate

NO NUMBERS UNTIL THE GATE SIGNS THEM

Every result on this site binds to a signed eval certificate at release. Until a checkpoint clears the gate there is nothing to show here — no targets dressed up as results, no cherry-picked leaderboard. When the numbers exist, they arrive with the certificate that proves them.

One factory. Every model.

Neptune models aren't hand-built — they come off a training line where every stage must prove itself before the next begins. The 27B is its first product, not its last.
