About
GPT-5.3 Instant is an updated version of ChatGPT’s most-used model, designed to make everyday conversations more fluid, helpful, and accurate. The release focuses on improving tone, relevance, and conversational flow based directly on user feedback. It reduces unnecessary refusals and cuts back on overly cautious disclaimers, delivering clearer and more direct answers when appropriate. The model also improves how it integrates web results, providing better-contextualized information rather than long lists of loosely connected links. Accuracy has been strengthened, with measurable reductions in hallucinations across both high-stakes domains and everyday queries. GPT-5.3 Instant enhances creative writing capabilities, producing more textured, emotionally resonant prose. It is available to all ChatGPT users and developers via the API under ‘gpt-5.3-chat-latest,’ with legacy versions scheduled for retirement.

About
ProseID turns legal and regulatory requirements into reusable digital workflows. Legal and compliance professionals can publish structured, versioned interpretations as guided assessments, compliance checklists, determinations or forms. Businesses can then use those interpretations without repeatedly rebuilding the same logic.
Every completed Flow validates the information provided and creates an auditable Record tied to the exact schema release used. The public registry shows the publisher, jurisdiction, legal references, release history, supported Flow types and completion price.
Verified legal and compliance professionals can earn when other organisations use their published work. ProseID serves law firms, compliance consultancies, privacy and security teams, regulated businesses, in-house legal departments and software developers. Workflows can be hosted by ProseID or integrated through its API.
