OpenAI has released GPT-6-Cyber, a model designed to investigate vulnerabilities, reproduce them in authorized environments, and verify fixes.
OpenAI released GPT-Image-2.6 Sunburst and Flare models, supporting adjustable complexity, SVG generation, animated GIF creation, and markup-guided editing.
Outbound SIP calling is now available to all organizations through the Live API. Connect GPT-Live to a phone number through your SIP provider. See the SIP guide.
You can now update the tools in an existing session in the Agents API public beta. Updates replace the full tool list. Function tools and MCP servers change on the next model call; built-in tools change by the next turn. Context compaction now runs in the background by default. Set compaction.async to false for blocking compaction.
Eligible ChatGPT Pro and Business subscribers can now claim up to $500 per month in free API credits by linking an API organization to their subscription.
OpenAI has released GPT-6.1 Terra, a model optimized for visual reasoning, computer use, and natural writing.
The Decisions API provides low-cost, focused decision-making capabilities for applications.
OpenAI updated Platform settings to allow organizations to restrict and select specific service tiers for individual projects or globally across all projects.
You can now choose 12-hour prompt caching in the API. 12-hour prompt caching keeps shared instructions, tools, and context cached longer to benefit from lower cached-input pricing, even when requests are hours apart. 12-hour cache writes cost 2.5x the input token price. Read more here.
OpenAI-hosted sandboxes in the Agents API now include the Artifact SDK and skills for creating and editing spreadsheets, presentations, and Word documents. Added Ultrafast mode to the Agents API. Set agent.service_tier to ultrafast with a supported model to reduce the time between generated tokens.
Added native Decisions integration in GPT-Live. Your app can act while your user is speaking or react to what Live says. Let Live call Decisions directly through native delegation, or trigger decisions as input or output transcript deltas arrive.
Added Ultrafast mode for GPT-6.1 Sol in the Responses API. Use gpt-6.1-sol with service_tier: "ultrafast" to reduce the time between generated output tokens. It is available to all API users, subject to rate limits, with global processing and US and EU data residency. See Ultrafast pricing.
Updated the chat-latest snapshot, which points to the latest model available in ChatGPT for Plus, Pro, Business and Enterprise users. We recommend leveraging the GPT-6 model family for production API usage, but feel free to use this model to test the latest improvements for chat use cases. The underlying model snapshot will be regularly updated.
Released the Decisions API in beta with gpt-6-luna. Turn text and images into typed answers 10x faster than the Responses API.
Added an in-product flow for HIPAA compliance support in API Organization settings > General. Admins of eligible organizations can now accept the standard Business Associate Agreement (BAA) and enable HIPAA compliance support for their organization. See the Help Center for eligibility, covered services, and configuration requirements.
Released GPT-6.1 Sol (gpt-6.1-sol) for complex coding and professional work at a lower cost than GPT-6 Astra. Standard pricing per 1M tokens for prompts with up to 272K input tokens is $2 input, $0.10 cached input, $2.50 cache write, and $10 output. GPT-6.1 Sol also supports Multi-agent in beta.
Fixed a bug in image encoding that degraded image understanding in GPT-6 Sol and GPT-6 Luna. This update improves results on visual tasks in the API and Codex, including computer use. If your use cases involve image inputs, we recommend rerunning your evaluations and retrying workflows affected by the issue.
Both models take text and image input and return text via the Responses and Chat Completions APIs. Up to 272K input tokens, GPT-6 Sol costs $2 input and $10 output per 1M tokens, and GPT-6 Luna $0.10 and $0.50.
Admins can allow only service-account keys, only user-owned project keys, or block new key creation at the organization or project level. Organization settings take precedence and existing keys are unaffected.
The Agents API runs agents on a managed Codex harness with OpenAI handling session orchestration, context compaction and recovery. It offers durable sessions, streaming, your own tools and MCP servers, and hosted or self-provided sandboxes.
gpt-rosalind-research is available through the trusted-access program at $5 input, $0.50 cached input and $25 output per 1M tokens. Billing begins October 5, 2026.
New long-running work controls let GPT-6 Astra keep working while tools run, accept extra instructions mid-response over WebSockets, and change reasoning effort mid-conversation while preserving the cached prompt.
Traffic ramping too quickly now returns 429 slow_down, while temporary model overload returns 503 server_is_overloaded. Honor Retry-After when present, otherwise use exponential backoff.
Connections to api.openai.com can now use IPv6.
Mutual TLS and X.509 workload identity federation can be configured in the Platform console, with access governed by organization roles and permissions, enabling keyless authentication.
whisper-1, gpt-4o-transcribe, gpt-4o-mini-transcribe and gpt-4o-transcribe-diarize shut down February 26, 2027; migrate to gpt-live-transcribe or gpt-transcribe. The Assistants API shut down August 26, 2026.
GPT‑5.6 is now available in Kiro, helping developers plan, build, review, and test software with better price-performance.
GPT-5.6 Sol input pricing drops 20% and output pricing 33%. The promotional price runs at least through November 21, 2026.
Set background to transparent with png or webp output in the Images API and Responses image tool for gpt-image-2 and gpt-image-2-2026-04-21. jpeg is not supported.
Ultrafast mode is a new API service tier for GPT-5.6 Sol that runs up to 14x faster than Standard processing, available to select customers.
Daybreak Blue gives approved defenders general-purpose models such as GPT-5.6 Sol for vulnerability discovery, code review and incident response, while Daybreak Red gives separately approved access to purpose-trained models.
The chat-latest snapshot now points to the latest model in ChatGPT for Plus and Pro users and will be updated regularly. OpenAI recommends GPT-5.6 Sol for production API usage.
Prompts over 272K tokens can now run in Fast mode on GPT-5.6 Sol, Terra and Luna, at up to 2.5x the speed of the Standard tier.
Usage and Costs dashboards and the Usage and Costs APIs now support an API key dimension for reporting and analysis.
From July 30, GPT-5.6 Luna costs 80% less and Terra 20% less. Fast mode replaces Priority Processing, giving GPT-5.6 Sol up to 2.5x speed at twice the price, and priority requests map to it automatically.
The provider manages projects, users, groups, roles, service accounts, certificates, invitations and project rate limits as code, with import and drift detection through standard Terraform workflows.
GPT Transcribe handles accurate file transcription and final transcripts of Realtime turns, while GPT Live Transcribe provides low-latency streaming. Both support transcription context, keyword hints and multiple expected languages.
A monthly cap makes affected API requests return 429 once tracked spend reaches the limit. Spend alerts can warn before traffic is interrupted.
GPT-5.6 Sol, Terra and Luna span frontier to high-volume workloads, and gpt-5.6 routes to Sol. The family adds Programmatic Tool Calling, explicit prompt caching controls, persisted reasoning and Pro mode, with multi-agent orchestration in beta.
GPT-Realtime-2.1 improves alphanumeric recognition, silence and noise handling and interruptions for voice apps, and the mini version is a faster, lower-cost distilled reasoning model.
The chat-latest snapshot now points to the latest Instant model used in ChatGPT and will be updated regularly. OpenAI recommends GPT-5.5 for production API usage.
