Guides
Sume guides: the API, Formats, agents, models, media tools and pricing, each answer dated and sourced.
Can ChatGPT make music videos? Song, clips, one render
With tools, yes: ChatGPT can have a track generated, a short clip made per section, and the clips cut over the song in one MP4 render.
Can ChatGPT make music? Getting a song or beat as audio
To get a song or a beat as an audio file, give ChatGPT a music tool: in developer mode it can call one over MCP and hand back a link to the track.
Can ChatGPT make product videos from a product photo?
Yes, with a video tool: in developer mode ChatGPT can send your product photo to a video model as the first frame and return a link to the clip.
Can ChatGPT make UGC videos? Script, voice, and lip sync
Not by itself. With a video tool connected in developer mode, ChatGPT can script, voice, and lip-sync a UGC-style clip, confirming paid calls first.
ChatGPT script to video: voice it, then cut to each line
ChatGPT writes the script; tools turn it into video. Voice it word for word, make one visual per line, and cut each to its sentence on a timeline.
Can ChatGPT make videos for free? Plans and per-clip costs
Not for free. Free ChatGPT accounts can't turn on developer mode, and the video tool it calls needs its own paid plan and bills each clip.
Can Claude make videos for free? What each plan allows
Claude outputs text on every plan. Free can add one video tool as a connector, but the tool bills each clip, so the videos themselves aren't free.
Can Claude Cowork make videos? Yes, through a connector
Not by itself: Cowork's models output text. Add a remote MCP video tool as a custom connector and a Cowork task can render clips and images as links.
Can Claude generate transparent images? Only in two steps
Claude can't generate images, transparent or not. Through an image tool it takes two calls: generate on a plain backdrop, then cut out a PNG with alpha.
Can Claude generate multiple images at once? Yes, via a tool
Claude can't draw, but through an image tool one call can ask for several images, up to 4 per model today, and Claude can send one call per scene at once.
Can Claude generate high resolution images? 4K via a tool
Claude can't make images itself. Through an image tool it can ask for a 4K tier on models that list one, then upscale a still up to 4x.
Can Claude create product images? From your photo, via a tool
Claude can't create images, but it can send your product photo to an image tool as a reference and describe the new scene. How it works and its limits.
Can Claude make video ads? Script yes, video via tools
Claude writes the ad's concept and script but outputs text. With video, voice, music and editing tools connected, it can render and assemble the ad.
Unlimited AI video generator subscription: does one exist?
An unlimited AI video plan still limits something. Sume has no unlimited or lifetime plan: paid plans include some usage, then bill per clip.

Cost to make an audiobook with AI narration
The cost to make an audiobook with AI is the book's characters times the TTS rate, plus small joining jobs. Worked budgets by manuscript size.
Text to speech commercial use: what the terms allow
Whether you can use text to speech audio commercially is set by the tool's terms and plan. What Sume's terms say, and what to check for a cloned voice.
Voice cloning API: clone once in the app, speak via the API
Sume has no API route that creates a voice clone. You clone once in the app, then send the voi_ id to the text to speech API on every call.
Text to speech streaming API: what Sume returns instead
Sume's text to speech API doesn't stream audio chunks. It returns a finished file per job; split long scripts into sentence jobs to start playback sooner.
Real time speech to text API: what a file-based API can do
Sume's speech to text API isn't real time: it transcribes recordings of up to 10 minutes at a URL. Chunked recordings give near-live transcripts.
C# text to speech: call a TTS API with HttpClient

C# HttpClient POST JSON with a Bearer token
Set Authorization with AuthenticationHeaderValue("Bearer", key), send a JSON body, then read the status and body before EnsureSuccessStatusCode.
PHP cURL POST JSON with a Bearer token
json_encode the body, pass the string to CURLOPT_POSTFIELDS, set Content-Type and Authorization headers, then check the status: cURL won't fail on a 4xx.
Golang HTTP POST JSON with headers and a Bearer token
http.Post can't set headers. Marshal the JSON, build it with http.NewRequest, set headers, send with a Client that has a Timeout, and close the body.
