OpenAI's developer platform for building with its models and APIs.

Recent stories
Multiple summaries of The Information report said OpenAI found inference optimizations that more than halved costs on some existing models. If that holds, it changes the margin, pricing, and usage-limit math behind ChatGPT and API serving even before new model releases arrive.
The Information reported that OpenAI is holding GPT-5.6 to a limited preview with customer-by-customer approvals during review. That would restrict who can benchmark or integrate the model until a broader rollout clears.
OpenAI said reinforcement learning on realistic conversations improved 44 of 53 alignment and benefit evaluations, including transfer from health-only training to deception and reward-hacking tests. The result suggests a broader behavioral shift rather than narrow task tuning, but the claim is based on OpenAI’s own eval mix rather than a single public benchmark.
OpenAI made GPT-5.4, GPT-5.5, and Codex generally available through Amazon Bedrock. AWS shops can now use OpenAI models inside existing IAM, compliance, and procurement workflows instead of adopting a separate vendor stack.
OpenAI said the API and ChatGPT were seeing elevated latencies before marking the incident resolved later in the day. User reports showed stalled GPT-5.5 sessions and retry loops, turning the issue into a production and coding-agent disruption.
OpenAI said ChatGPT, Codex, and the Responses API can reach private MCP servers over outbound-only HTTPS without inbound exposure. The same enterprise update adds workload identity federation plus admin controls for spend alerts, allowlists, retention, and hosted tools.
OpenAI launched Guaranteed Capacity, offering long-term reserved access to model compute in exchange for one- to three-year commitments and discounted tokens. It matters because enterprises can now buy explicit supply guarantees instead of relying on shared capacity during a compute-constrained period.
OpenAI launched the OpenAI Deployment Company and tied it to Tomoro’s acquisition, giving the unit 150 forward-deployed engineers and $4 billion in initial backing from 19 partners. It matters because OpenAI is packaging services, deployment help, and organizational integration as part of the product stack instead of leaving enterprise rollout to outside consultancies.
AWS and OpenAI moved their expanded partnership into limited preview, bringing OpenAI models, Codex, and Bedrock Managed Agents onto AWS. That gives teams a direct AWS path for OpenAI-backed agent workflows instead of waiting on the earlier coming-soon timeline.
