OpenAI is testing a new GPT-5-based AI agent "GPT-Alpha"

GPT-5 Agent

OpenAI is internally testing a new version of its AI agent, which uses a special version of GPT-5 dubbed “GPT-Alpha.”

Earlier today, OpenAI accidentally pushed an unreleased feature to everyone.

As you can see in the above screenshot shared on X, the new feature is called “Agent with Truncation” and it can be found under Alpha Models.

The system prompt of the new GPT-Alpha agent confirmed that the agentis designed to execute the following features:

  • Browse the web for up-to-date/niche information
  • Generate and edit images
  • Write, run, and debug code
  • Create/edit documents, spreadsheets, and slides Constraints.
  • Do not access or expose private info unless explicitly provided

The internal prompt also confirms that it’s an agent that uses “GPT-5 for Advanced Reasoning and Tool Use.”

It’s unclear when the new Agent will begin rolling out, but Sam Altman previously confirmed that OpenAI plans to ship advanced features for paid customers only due to the requirement of additional compute.

This new agent could be one of those premium features for ChatGPT, at least intially.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).

Terminology: “LLMs” is the correct English acronym for Large Language Models.
