Orca vs ChatGPT Plugins

Orca is an AI model with 13 billion parameters designed to learn the reasoning process of large foundation models like GPT-4. It achieves this by imitating detailed explanation traces and step-by-step thought processes rather than just mimicking output styles.

What sets Orca apart is its use of rich explanation traces generated by GPT-4 and teacher guidance from ChatGPT, enabling it to progressively improve its reasoning capabilities. This approach allows Orca to surpass many instruction-tuned models on complex zero-shot reasoning benchmarks.

Orca is trained on large-scale, diverse imitation data with careful sampling to enhance learning quality. It performs competitively on professional and academic exams such as the SAT, LSAT, GRE, and GMAT without requiring chain-of-thought prompting.

The model addresses challenges common in small model training, including limited learning signals and lack of rigorous evaluation, by focusing on learning the reasoning process. Microsoft Research continues to develop Orca through projects like Orca 2 and domain-specialized variants such as Orca-Math.

Orca is part of Microsoft's broader AI research ecosystem, which emphasizes responsible AI development, transparency, and practical applications integrating insights from large language models.

ChatGPT Plugins was OpenAI's 2023 extension system that let ChatGPT call third-party APIs for live data, calculations, and external services. Plugins appeared as tools the model could invoke during a conversation after users enabled them in ChatGPT. OpenAI's March 2023 announcement listed launch partners including Expedia, Instacart, KAYAK, Klarna, OpenTable, Shopify, Slack, Wolfram, and Zapier.

The beta also shipped OpenAI-built plugins for web browsing via Bing, a sandboxed Python code interpreter, and an open-source retrieval plugin for private document search. Developers published plugins through a manifest file and OpenAPI spec, and ChatGPT Plus subscribers were the first users to enable them in chat.

OpenAI deprecated the plugin beta in favor of custom GPTs. The official blog page now states plugins have been deprecated, and OpenAI ended new plugin conversations on March 19, 2024, with full shutdown on April 9, 2024. GPTs with custom actions replaced the integration model for developers and ChatGPT users.
