Food ChatGPT Plugins were the subset of third-party plugins published in the ChatGPT plugins store between March 2023 and April 2024 that focused on cooking, recipes, grocery shopping, restaurant discovery, and food delivery. The plugin framework launched in beta on March 23, 2023 [1], and OpenAI deprecated it on March 19, 2024, blocking new plugin conversations, then shut it down entirely on April 9, 2024 [4]. Food plugins are therefore a deprecated, historical category. The two best known food entries (Instacart for grocery ordering and OpenTable for restaurant reservations) were among the twelve external partners named in OpenAI's original launch slate [1][6]. The category sat alongside Beverage ChatGPT Plugins and overlapped with Shopping ChatGPT Plugins at the retail end of the catalogue. Operated by OpenAI as part of the broader plugin program for ChatGPT, the food category drew unusual attention at launch because Instacart and OpenTable were household consumer brands that gave the plugin program early credibility. The succession chain that replaced plugins runs from Custom GPTs and the GPT Store (January 2024) to GPT Actions and then to the Model Context Protocol (November 2024) [3][5][13]. This article treats the food category as a historical reference for an early experiment in connecting a large language model to live food and grocery services.
OpenAI announced ChatGPT plugins on March 23, 2023 in a blog post titled "ChatGPT plugins." The post described plugins as the company's first plugins for the chatbot and presented them as a way to "help ChatGPT access up-to-date information, run computations, or use third-party services" [1]. The launch slate listed twelve external partners (Expedia, FiscalNote, Instacart, KAYAK, Klarna, Milo, OpenTable, Shopify, Slack, Speak, Wolfram, and Zapier) plus two first-party plugins, a code interpreter and a web browsing tool [1][6]. Two of those twelve external partners were food-adjacent: Instacart for grocery ordering and OpenTable for restaurant reservations [1]. Access at launch was gated behind a waitlist and rolled out gradually to ChatGPT Plus subscribers through the spring of 2023 [1].
A food plugin, like every plugin, was a small piece of server software exposing an HTTP API to the chatbot. It consisted of two artefacts on the developer's domain: a manifest file named ai-plugin.json served at /.well-known/ai-plugin.json, and an OpenAPI specification describing the available endpoints [1]. ChatGPT used the manifest to describe the plugin to the GPT-4 model in natural language and used the OpenAPI document to plan and validate calls. The food category therefore was not a single product but a slice of this open developer ecosystem, defined by subject matter (cooking, groceries, restaurants) rather than by any separate technical framework.
On May 12, 2023 OpenAI announced that web browsing and plugins would become available to all ChatGPT Plus subscribers the following week [2]. The plugin store opened for general access on May 19, 2023, after which the catalogue grew quickly. Independent developers added recipe assistants, ingredient databases, restaurant search engines, and food delivery integrations across the second half of 2023. The food category in the plugin store therefore had two distinct phases: a short alpha period in March and April 2023 dominated by the launch partners, and a much larger general-availability phase from late May 2023 through early 2024 in which long-tail third-party plugins outnumbered the original brand-name entries.
The key dates for the food category are summarised in the table below.
| Date | Event |
|---|---|
| March 23, 2023 | OpenAI announces ChatGPT plugins. Instacart and OpenTable are listed among the twelve external launch partners [1]. |
| May 12, 2023 | OpenAI announces general availability of plugins for ChatGPT Plus subscribers [2]. |
| May 19, 2023 | Plugin store opens to all Plus subscribers. Third-party recipe and food plugins begin to appear in volume [2]. |
| November 6, 2023 | OpenAI DevDay introduces Custom GPTs and Actions. Plugins are publicly described as a sunsetting feature [3]. |
| January 10, 2024 | GPT Store opens, beginning the migration of plugin functionality into branded GPTs [5]. |
| March 19, 2024 | OpenAI deprecates the plugins beta. No new plugin conversations can be started after this date [4]. |
| April 9, 2024 | The plugin store and plugin runtime are turned off for end users [4]. |
ChatGPT used the manifest to describe each food plugin to the model and used the OpenAPI document to plan and validate calls. The practical capabilities clustered into a small number of recurring patterns:
Almost no food plugin completed a transaction inside ChatGPT itself. The standard pattern was for the plugin to return a deep link (for example to a populated grocery cart or to a restaurant reservation page) which the user opened in a browser to finish the task. This boundary was a deliberate part of the plugin design: ChatGPT could compose, search, and summarise, but the actual purchase or booking happened on the partner's own site, where existing payment, identity, and trust mechanisms already lived.
The two best-documented food plugins are the launch partners that OpenAI named in its original March 23, 2023 announcement [1].
Instacart was one of the twelve external launch partners on March 23, 2023 [1]. In its own announcement post, dated April 6, 2023, Instacart described the plugin as letting ChatGPT users "turn the ever-present 'dinner dilemma' into instant inspiration and, ultimately, instant gratification with ingredients delivered to their door in as fast as an hour" [9]. The company framed the integration this way: "By combining ChatGPT's ability to enable people to express their needs in natural language, with Instacart's ability to make those needs instantly shoppable" [9]. In practice a user described a meal or recipe and then converted the resulting ingredient list into a shopping cart at a local grocery retailer. A typical interaction read like this:
The Instacart plugin was repeatedly cited in coverage of the plugin launch as a flagship example of what plugins were for, because it tied together a clearly defined consumer task (cooking dinner) with a clearly defined retail backend (a same-day grocery service) [6][7].
OpenTable was the second food-adjacent launch partner and said it was "the first restaurant tech company to partner with ChatGPT" [10]. The plugin let ChatGPT search OpenTable's reservation index and return restaurants that matched a user's natural-language query ("find me a quiet Italian restaurant near Union Square next Friday at seven"). Per OpenTable, ChatGPT would "provide direct links to book on OpenTable in response to consumer queries" such as a request for a highly reviewed brunch spot for a specific occasion and city [10]. The plugin returned a short list of candidate restaurants with metadata such as cuisine, price range, and a reservation link, and booking itself was finalised on OpenTable's own pages.
The presence of OpenTable in the launch slate (alongside Expedia and KAYAK in travel) signalled that OpenAI's plugin program was aimed at integrating with mainstream booking platforms rather than rebuilding them inside ChatGPT [1].
Wolfram, a launch partner usually associated with mathematics and curated reference data, exposed nutritional and food-composition information through its Wolfram Alpha back-end [1]. Though not normally classed under food, it was used heavily for food-adjacent queries about calories, macronutrients, cooking unit conversions, and ingredient composition. Its dedicated wiki entry is Wolfram GPT.
After general availability on May 19, 2023, independent developers published recipe-oriented plugins covering recipe search by ingredient or dietary tag, multi-day meal planners with consolidated shopping lists, calorie and macro lookups against public nutritional databases, and restaurant search wrappers built on public review APIs [2]. Because this wiki only documents plugins that can be cross-referenced to a primary source, the article does not enumerate them by name. Most were short-lived. With the deprecation of the plugin program in April 2024, they either shut down or migrated their backends to GPT Actions inside a Custom GPT [4].
Three workflow patterns dominated discussion of the food category during the plugin era.
This was the canonical Instacart-style flow and was used in OpenAI's own launch demos:
This workflow is the one most often cited in retrospectives of the plugin era because it tied together generation (recipe), planning (consolidated list), and action (cart link) in a single conversation.
The restaurant flow was simpler and more familiar:
In contrast to the grocery flow, the restaurant flow rarely reached a confirmed booking inside ChatGPT itself. The chatbot's role was discovery, not transaction.
A quieter but heavily used workflow involved asking the chatbot for nutrition facts or ingredient substitutions. The base model could answer many such queries from training data, but plugin-backed answers were preferred for current or branded data. Wolfram and several smaller nutritional-database plugins served this need.
The deprecation arrived in two steps. At OpenAI DevDay on November 6, 2023 the company introduced Custom GPTs and announced that plugins would eventually be retired in favour of GPTs and their tool-calling layer, called Actions [3]. The plugin store stopped accepting new submissions soon afterward. On March 19, 2024 OpenAI's help-center notice, titled "Winding down the ChatGPT plugins beta," took effect: users could no longer install plugins or start new conversations with them [4]. Existing plugin conversations kept working only until April 9, 2024, when plugins were turned off entirely [4]. The notice pointed users and developers to GPTs and the GPT Store for equivalent functionality.
OpenAI gave several public reasons for ending the plugin program. The food category illustrated all of them.
For the food category, the discovery problem and three-plugin limit were the most painful. A typical Sunday meal-planning session wanted a recipe plugin, a grocery plugin, and a nutrition plugin at once, which filled the plugin budget and left no room for a pairing plugin or a calendar plugin.
The immediate successor to the plugin program is the combination of Custom GPTs and the GPT Store, which opened on January 10, 2024 [5]. A GPT bundles three things: custom instructions, optional knowledge files, and Actions (the new name for the plugin-style API call layer). For the food category, this packaging changed the shape of the catalogue.
Where the plugin store presented dozens of single-purpose plugins (one for recipe search, one for grocery, one for nutrition), the GPT Store presented a smaller number of branded assistants such as "meal planner" or "restaurant scout." Each GPT could call the same kind of HTTP backend a plugin used to call, so the underlying technology was largely unchanged, but discovery moved from a flat list of plugins to a marketplace of named applications.
The Actions layer underneath GPTs uses the same OpenAPI specification format that plugins used. Most food plugin developers who continued operating in 2024 ported their backends to Actions inside a Custom GPT with limited code changes. A user no longer chose individual plugins inside a chat: they chose a GPT in the GPT Store, opened it, and the relevant Actions ran automatically.
The longer-term successor to the plugin idea is the Model Context Protocol (MCP), an open standard that Anthropic introduced in November 2024 to connect AI assistants to external tools and data sources [13]. MCP generalised the plugin concept beyond a single vendor: it was subsequently adopted by OpenAI and Google DeepMind, and OpenAI added MCP support to ChatGPT and its Agents and Responses APIs during 2025 [13]. A food integration in the MCP era is an MCP server (for groceries, recipes, or reservations) that any MCP-capable assistant can call, rather than a plugin tied to one chatbot. The lineage therefore runs from food ChatGPT plugins (2023) to GPT Actions inside Custom GPTs (2024) to vendor-neutral MCP servers (2024 onward).
The table below contrasts the food category before and after the transition.
| Aspect | Plugin era (2023 to 2024) | GPT and MCP era (2024 onward) |
|---|---|---|
| Discovery | Flat plugin store inside ChatGPT | Branded GPTs in the GPT Store; MCP servers across vendors |
| Activation | User toggled up to three plugins per chat | User opened a single GPT; MCP servers connect automatically |
| Backend contract | OpenAPI plus ai-plugin.json manifest | OpenAPI plus a GPT configuration; MCP protocol for cross-vendor use |
| Persistence of identity | None. Plugins were stateless API wrappers | GPTs carry instructions and knowledge across sessions |
| Vendor scope | OpenAI / ChatGPT only | GPT Store is OpenAI; MCP is an open, multi-vendor standard |
| Revenue model | None for developers | Revenue share announced for GPT Store |
| Migration cost for developers | n/a | Generally low: same API, repackaged behind a GPT or MCP server |
Imagine ChatGPT as a smart helper that only knew what it had read in books. For about a year (2023 to 2024), you could plug in extra "apps" to give it new powers. One food app, Instacart, let you say "make me dinner for four" and then put all the groceries in a cart for you. Another, OpenTable, found you a restaurant and a table to book. You could only snap on three of these apps at a time, and they often did not work very well. So the helper's makers turned them off in April 2024 and replaced them with better tools: first "GPTs" you can open like apps in a store, and later a shared standard called MCP that lets many AI helpers, not just ChatGPT, plug into the same food services.
