What can ChatGPT do on Instagram?
On Instagram, ChatGPT can post Reels and feed images with a caption and hashtags. Every booking runs through the same rules as the ClipSpeed app.
Video and Image posts
Instagram takes video and image through ClipSpeed. Video: MP4, MOV or WebM up to 1 GB by public link (posted as a Reel), or a finished ClipSpeed clip. Image: JPG, PNG, WebP or GIF up to 25 MB by public link.
2,200 characters, checked at booking
Instagram's own arithmetic. Too long is refused with the real count, never trimmed at send time.
Exact time or refused
Name the minute and ChatGPT books it, or you are told why not and offered the next open slot. A booked Instagram post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. ChatGPT shows the plan, with each slot and the day's remaining cap, and books only on your yes.
Clips cut in the same chat
Submit a video or stream link, get captioned 9:16 clips with a viral score, and post the best as native video on Instagram. No download, no re-upload.
Pacing and numbers
Image posts on Instagram are at least 120 minutes apart, up to 4 a day. Video on Instagram is at least 4 hours apart, up to 4 a day under your plan. After a post goes out, ChatGPT can read back views and engagement where Instagram provides them.
How does ChatGPT post to Instagram through ClipSpeed?
You describe what you want in plain language and ChatGPT makes the ClipSpeed calls. A typical conversation has three beats.
Find your Instagram channel
Ask ChatGPT whether Instagram is connected. It calls list_channels and reads platform_settings, so it also knows what Instagram accepts and the limits before you write a word.
Compose within the rules
Describe the post. ChatGPT drafts within Instagram's limits, and leaves URLs out because they are removed anyway; mention a clip or a file and it attaches it.
Schedule or publish
Name a time, or say now. The slot is booked exactly or refused with the next open one, and the reply carries the id you can cancel or edit by.
Instagram settings reference
These are the schedule_post fields that apply to Instagram. Mention any of them in plain language and ChatGPT sets them; the server checks them at booking.
| Field | Type | Required | What it does on Instagram |
|---|---|---|---|
platforms | string[] | Yes | Include "instagram". Up to ten platforms per call; each books its own slot. |
text | string | No | The caption, up to 2,200 characters including hashtags. URLs are removed; Instagram captions do not link. |
hashtags | string[] | No | Appended to the caption and counted toward the limit. Instagram allows up to 30. |
media_kind | image | video | No | Detected from the file when omitted. Video posts as a Reel; an image posts to the feed. |
clip_id or media_url | string | One of the two | A finished ClipSpeed clip (Reel), or a public https link to an image up to 25 MB or a video up to 1 GB. |
scheduled_at | ISO 8601 | No | Exact or refused with the next open slot. Omit to post as soon as possible. |
preview | boolean | No | Plan only; nothing is booked. |

Instagram limits and gotchas to know
Instagram enforces a few rules that ChatGPT and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- Captions are limited to 2,200 characters with hashtags counted; a longer caption is refused at booking, never trimmed at send time.
- Links in captions are removed before posting. Instagram does not make caption links clickable, so point people to the bio instead.
- Instagram takes video (as a Reel) and images. A text-only request is refused with a message that names what Instagram accepts.
- Images on one account are at least two hours apart and Reels four hours apart, with a daily cap from your plan. The booking names the next open slot when a time is taken.
- Stories are not part of the agent tools today. The page says Reels and feed posts because that is what posts.
| Rule | |
|---|---|
| Accepts | Video, Image |
| Text limit | 2,200 characters |
| Title | No title field |
| Links in the caption | Removed before posting (Instagram captions do not link, and link-heavy captions are down-ranked) |
| Pacing | Image posts on Instagram are at least 120 minutes apart, up to 4 a day. Video on Instagram is at least 4 hours apart, up to 4 a day under your plan. |
| Formats | Image: JPG, PNG, WebP or GIF up to 25 MB by public link. Video: MP4, MOV or WebM up to 1 GB by public link (posted as a Reel), or a finished ClipSpeed clip. Aspect: 9:16 for Reels, 1:1 or 4:5 for feed images |

What Postiz-style schedulers cannot do
Cut the clips first
ChatGPT does not need finished video to start. Hand it a YouTube link, a podcast, a stream VOD or a local export. ClipSpeed finds the moments, cuts them to 9:16 with word-by-word captions, scores each one 0 to 100 for shareability, and returns them in the same conversation. ChatGPT picks by score, writes the caption from the transcript, and books the clips on Instagram. Three tool calls, one approval, no download and no re-upload.
- Clips arrive with a title written from the hook, a transcript and a viral score, so the agent can choose and caption without watching the footage.
- Live streams can be clipped while they are still on air; the agent books the highlights for the next morning before the stream ends.
- Every clip is already hosted, so
schedule_posttakes its id directly. Nothing moves through your laptop.
submit_to_clipspeedPaste the link. ClipSpeed starts the job and returns a project id.check_clipsPoll with the project id. Back come the finished 9:16 clips with titles, transcripts, viral scores and preview links.schedule_postPass the clip id, the platforms, a caption and a time. ChatGPT shows the plan with preview: true, you say yes, it books.generate_image or generate_videoDescribe the shot. ClipSpeed runs it on the model that fits (Seedance, Kling, Veo, Nano Banana Pro, GPT Image and others) and quotes the credits first.wait_for_generationReturns the hosted result link and a preview the agent can show you.schedule_post with media_urlThe result link goes straight into the booking on Instagram. The caption, the time and the file are approved together.The other half nobody else has
Generate the image or video, then post it
A product shot for Instagram, a 16:9 announcement graphic for X, a six-second opener before a clip: ChatGPT can make an image or a short video with ClipSpeed's image and video models and book the result in the same reply. There is no separate design tool, no export, no upload page. The generated file is hosted, so media_url is the only thing the booking needs.
- The price in credits is quoted before anything renders, within the per-generation and daily caps you set in Settings.
- Results are previewed in the conversation, so you approve the picture and the post at once.
- Images post as JPG, PNG or WebP up to 25 MB; video posts as MP4, MOV or WebM up to 1 GB.
What is ChatGPT?
ChatGPT is OpenAI's assistant on chatgpt.com and in its desktop and mobile apps. On the web it can reach outside tools through connectors, including custom connectors built on the Model Context Protocol (MCP) when Developer mode is on. With the ClipSpeed connector added, ChatGPT can clip a video, generate images and video, and schedule posts to your connected platforms, confirming each booking before it runs.
How ClipSpeed works with ChatGPT
- ChatGPT discovers the ClipSpeed tools when the connector is enabled in a chat
- It reads each platform's rules with
platform_settingsbefore writing, so limits are met the first time schedule_postbooks an exact time or refuses with the next open slot; a taken slot is never silently movedpreview: truereturns the plan with every slot and books nothing; you confirm and it books- OAuth means ChatGPT never holds a platform password and ClipSpeed never holds your OpenAI login

Instagram and ChatGPT: frequently asked questions
How do I post to Instagram from ChatGPT?
In ChatGPT on the web, open Settings → Connectors → Advanced and turn on Developer mode. Back in Connectors, choose Create. Name it ClipSpeed, paste https://api.clipspeed.ai/mcp as the server URL, pick OAuth, and save. Connect Instagram in ClipSpeed (or ask ChatGPT for a connect link; it is private and valid for ten minutes), then describe the post in plain language. ChatGPT reads the Instagram rules, drafts within them, shows the plan and books on your yes.
What can ChatGPT post to Instagram through ClipSpeed?
Post Reels and feed images with a caption and hashtags. Instagram takes video and image posts; a text-only request is refused with a message naming what it accepts. Text is limited to 2,200 characters.
Which Instagram settings can ChatGPT control?
The fields in the settings reference above: text, hashtags, media_kind, clip_id or media_url, scheduled_at, preview. Mention any of them in plain language ("unlisted", "tomorrow at 9", "preview first") and ChatGPT sets the matching field before it books.
Do I need a Instagram API key or developer account?
No. You connect Instagram to ClipSpeed once through Instagram's own sign-in, and ChatGPT talks to ClipSpeed over OAuth. No Instagram developer key, bearer token or password is pasted anywhere.
How many Instagram posts a day can ChatGPT schedule?
Image posts on Instagram are at least 120 minutes apart, up to 4 a day. Video on Instagram is at least 4 hours apart, up to 4 a day under your plan. When a time is taken, the booking is refused with the next open slot rather than moved. Ask for preview to see a day's plan and the remaining cap before anything is booked.
Can posts go out to Instagram while I am away?
Yes. Once booked, ClipSpeed publishes at the scheduled minute whether or not ChatGPT is open. For unattended runs that decide what to post, use a headless agent such as Claude Code or Codex with the same account.
Is posting to Instagram from ChatGPT different from Codex?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. ChatGPT: chatgpt.com (developer mode for custom connectors). Codex: terminal, ide, codex.openai.com, reads your repo; codex exec runs a prompt unattended for cron and ci.
