OpenAI

OpenAI's top tier, built for the hardest long-running agentic work: large software-engineering tasks, operating computers and browsers, research and polished deliverables. It is OpenAI's priciest model and the first it rates at its “Critical” cybersecurity level, so some security requests are refused.

The current mid-tier GPT: an upgraded Sol that OpenAI positions close to Astra on agentic coding, computer use and professional tasks at one-fifth of Astra's token prices, with unusually cheap cached input. It superseded GPT-6 Sol a week after that model launched.

Middle tier of the previous generation, roughly the old “mini” slot. There is no Terra in the GPT-6 lineup, where GPT-6.1 Sol now costs less per output token and scores far higher — so it mostly matters for existing deployments.

The smallest and cheapest GPT-6 model, meant for narrow, well-scoped, high-volume jobs such as extraction, classification, triage and small edits — while keeping the 1M-token context window and the full tool set.

OpenAI's largest open-weights model: a text-only reasoning model from August 2025 that can be self-hosted on a single H100-class GPU and fine-tuned. It trails OpenAI's API models by a wide margin, and no newer open-weights release has followed.
