OpenAI is the pioneer of modern large language models, powering GPT-6 Astra, GPT-5.6 Sol, Terra, and Luna. On ARMES, all OpenAI models run via verified Zero Data Retention enterprise pipelines, guaranteeing your reasoning prompts and code remain private.
Strict Zero Data Retention (ZDR): Requests are processed ephemerally in RAM. No user data, prompts, or completions are stored, indexed, or used for model training.
Available under ARMES unified subscription without separate API keys or billing agreements.
OpenAI's flagship September 2026 frontier model with a 1.05M context window, MoE architecture, and SOTA reasoning across coding, formal mathematics, and long-horizon agentic automation.
GPT-6.1 Sol is OpenAI's mid-tier GPT-6-series flagship (released Sept 29, 2026, ~7 days after GPT-6 Sol), delivering "near-Astra" agentic coding, computer-use and document-heavy performance at $2/$10 per 1M tokens with a 1.05M-token context window and native image input. It replaces GPT-6 Sol in ChatGPT Work/Codex and the API slug gpt-6.1-sol.
GPT-6 Sol is OpenAI's mid-tier, cost-efficient high-end GPT-6 model (launched 22 Sept 2026, ~three weeks after flagship GPT-6 Astra), exposing a 1,050,000-token context window, 128K max output, image input, selectable reasoning effort, and hidden test-time reasoning tokens at $2/$10 per 1M tokens — positioned between GPT-6 Astra (quality) and GPT-6 Luna (throughput/price).
OpenAI's most capable model and the top of the GPT-5.6 family (released Jul 2026).
OpenAI's smartest model (released Apr 23, 2026).
GPT-5.4-mini is a high-performance foundation model engineered by OpenAI, accessible with Zero Data Retention on ARMES.
GPT-5.4-nano is a high-performance foundation model engineered by OpenAI, accessible with Zero Data Retention on ARMES.
