What they do. How to try them. What is actually available.
A selection of open-weight and hosted models, ordered by announcement date. When a source gives only a month, it appears after dated entries in that month, without an invented day. Each entry links to the provider's source. This is editorial coverage, with no blended ranking or inferred adoption numbers.
A model for visual reasoning, computer use and writing. OpenAI positions Terra for frequent, well-defined work such as reading documents and operating software.

A Claude model for demanding work across large codebases and long tasks. Its release changes thinking behavior and integration requirements, which developers should check before migrating.
Focus / inputs
Coding, computer use and knowledge work
Access
Claude Platform as claude-opus-5-5 and supported cloud platforms, including AWS, Google Cloud and Azure. Some specialist work requires verified access.
Two GPT-6 models aimed at different workload sizes and cost budgets. Sol handles demanding everyday tasks, while Luna is the smaller option for faster iteration and larger volumes.
Focus / inputs
Reasoning, coding and computer use
Access
OpenAI API as gpt-6-sol and gpt-6-luna, plus ChatGPT Work and Codex. The launch announcement describes access by subscription and a phased rollout.
A GPT-6 model for difficult software, research and professional tasks that span multiple steps. It combines reasoning with browser and computer interaction; tools and execution environments determine what an application can do.
Focus / inputs
Reasoning, coding and computer use
Access
OpenAI API as gpt-6-astra. ChatGPT and cloud-platform access was phased at launch and depends on the service and workspace settings.
Two access configurations of the same underlying model. Fable is generally available; Mythos uses different safeguards for approved specialist work. The official announcement gives a month without an exact day.
Focus / inputs
Coding, knowledge work and scientific research
Access
Fable 5.1: Claude API and supported cloud platforms. Mythos 5.1: restricted trusted access programs and Claude Security; it is not a generally available API alternative.
