GPT-6 Astra enters limited rollout above the GPT-5.6 family.
OpenAI introduced GPT-6 Astra with a 1.05M context window, 128K maximum output, and $10/$50 per million input/output token pricing. Initial access is limited to Trusted Access enterprises; broader API and Plus, Pro, Business, and Enterprise access was announced for the coming days.
Do not replace a production GPT-5.6 budget with Astra assumptions yet. Treat Astra as a separately governed high-cost pilot until access, safety controls, and workload gains are validated for the buyer's organization.

GPT-5.6 API prices fall across Sol, Terra, and Luna.
Current OpenAI model documentation lists Sol at $4/$20, Terra at $2/$12, and Luna at $0.20/$1.20 per million input/output tokens.
Re-run routing and unit-cost models: Luna is now one-fifth of its launch input and output price, while Sol and Terra also became cheaper for production agent workloads.

ChatGPT Work creates a distinct outcome-agent surface between Chat and Codex.
ChatGPT Work handles longer multi-step deliverables across enabled apps and files, including documents, spreadsheets, presentations, reports, and Sites. Cloud Work is available through web and mobile, while desktop access to local files and apps needs permission. Its usage follows the same structure as Codex rather than an unlimited-chat model.
Budget Work as an agentic consumption surface and validate workspace eligibility, roles, enabled apps, allowed actions, and cloud-versus-local access before rollout. Do not assume an included chat seat grants every file-creation or desktop-control workflow.

ChatGPT Business annual pricing is now $20 per user per month, while Codex usage moves to a token ratecard.
OpenAI reduced annual Business pricing from $25 to $20 per user per month while monthly pricing remains $30. Codex usage and purchased credits now follow the token ratecard, and new Codex-only pay-as-you-go seats are no longer available for Business workspaces.
Business becomes a lower fixed-seat baseline, but coding-heavy teams must separately forecast token-credit consumption. Do not use the Business seat price as the complete Codex budget.

GPT-5.6 replaces GPT-5.5 across ChatGPT, Codex, and the OpenAI API.
OpenAI launched GPT-5.6 Sol, Terra, and Luna on July 9 with configurable reasoning, multi-agent and programmatic tool-calling paths, and API prices of $5/$30, $2.50/$15, and $1/$6 per million input/output tokens.
Teams should now model OpenAI as a three-tier GPT-5.6 family instead of a single premium flagship. Sol keeps GPT-5.5's flagship token price while improving agentic and computer-use performance; Terra and Luna create clearer cost-down paths for scaled assistants and subagents.
