Alchemax-5 Frontier

Our most capable general-purpose foundation model. Native 2-million-token context window, real-time multimodal perception across text, code, vision, and audio, and industry-leading reliability.

Alchemax-5 represents a generational leap beyond conventional large language models. Trained on our unified sparse-expert architecture with verifiable post-training alignment, Alchemax-5 processes entire codebases, legal discovery bundles, and multi-hour video streams in a single pass with near-perfect needle-in-a-haystack recall.

Alchemax-o3 Pro Reasoning

Engineered for the hardest problems in mathematics, autonomous software engineering, formal verification, and scientific discovery through tree-search test-time reasoning.

Alchemax-o3 Pro is trained via large-scale reinforcement learning over formal proof environments, compiler toolchains, and executable sandboxes. Before emitting a final answer, o3 Pro explores and verifies multiple reasoning trajectories, backtracking automatically when an intermediate hypothesis fails verification.

Aegis Autonomous Agents

Sandboxed, multi-step autonomous agents capable of operating web browsers, terminals, enterprise ERPs, and CI/CD pipelines with human-in-the-loop governance.

Moving from passive chat assistants to reliable autonomous execution requires more than a raw model—it requires a secure, deterministic runtime. Aegis pairs Alchemax-o3 Pro with isolated micro-VM sandboxes, browser control, and granular permission boundaries.

Alchemax-4.5 Flash & Embeddings

Ultra-low-latency frontier intelligence distilled for high-frequency production workloads, real-time voice agents, and billion-scale vector retrieval.

When building real-time customer voice interfaces, inline IDE code completion, or high-volume document classification pipelines, latency and unit economics are paramount. Alchemax-4.5 Flash delivers GPT-4-class intelligence at a fraction of the compute cost and over 380 tokens per second.

Vanguard Sovereign AI Cloud

Private, air-gapped or VPC-peered frontier model deployments hosted exclusively within UK and European sovereign data centres.

Regulated institutions in defence, healthcare, banking, and central government cannot send sensitive data across public multi-tenant endpoints. Vanguard Sovereign AI Cloud deploys the complete Alchemax model stack inside single-tenant UK and European clusters.
