Frontier model lab · Series B

We train
intelligence you can trust.

Axondyne trains, fine-tunes, and aligns frontier AI models for teams that can't afford to ship a black box. From pretraining at scale to domain-specific deployment — we own the whole pipeline.

Capabilities

Everything it takes to train a model — under one roof.

Most labs hand you weights and wish you luck. We stay accountable from the first token of pretraining to the last evaluation in production.

🧠

Pretraining at scale

Dense and mixture-of-experts architectures trained on curated, deduplicated, license-clean corpora across our H100 fabric.

🎯

Fine-tuning & RLHF

Supervised fine-tuning, DPO, and reinforcement learning from human feedback tuned to your domain, tone, and policies.

🛡️

Alignment & safety

Red-teaming, constitutional training, and refusal calibration so your model behaves under adversarial pressure — not just in demos.

📊

Evaluation suites

Custom benchmarks, regression gates, and live eval dashboards that catch drift before your users do.

Inference optimization

Quantization, speculative decoding, and distillation that cut latency and cost without melting your accuracy.

🔒

Private deployment

Ship to your VPC, on-prem, or air-gapped. Your data and your weights never leave your perimeter.

The pipeline

From raw data to a model you can defend.

A repeatable, audited path — so every model ships with a paper trail, not a shrug.

01

Data & curation

We ingest, clean, deduplicate, and document your corpus with full provenance and licensing checks.

02

Train & tune

Pretrain or fine-tune on dedicated GPU capacity with live loss curves and reproducible configs.

03

Align & evaluate

RLHF, red-teaming, and your custom eval gates run automatically on every checkpoint.

04

Deploy & monitor

One-click rollout to your infra with drift alerts, usage analytics, and rollback baked in.

The platform

Reproducible training, in a single command.

Define your run as code. Version everything — data, config, weights, evals. Hand any teammate the manifest and they get the exact same model, byte for byte.

  • Declarative training manifests with full lineage tracking
  • Automatic checkpointing, resumption, and cost guardrails
  • Built-in eval gates that block bad checkpoints from shipping
  • One API for training, fine-tuning, and inference
