Hedra vs Elyumfor GPT Image 2
Hedra bills GPT Image 2 from 3.57 cents a generation; Elyum charges 6 credits ($0.06) only when you keep a take and refunds the rest.
GPT Image 2 is OpenAI's image model, released April 21, 2026 as the engine behind ChatGPT Images 2.0. Practitioners use it when type has to stay readable: posters, infographics, UI mockups, packaging, comics, and magazine-style pages. It holds English plus Japanese, Korean, Chinese, Hindi, and Bengali, and it is built to follow a brief and keep dense layouts usable. OpenAI called out small text, iconography, and dense layouts as the usual failure points it holds. TechCrunch's first look could put a restaurant menu in a frame without invented words. On Elyum it is text to image and image editing, with five aspect ratios. See the GPT Image 2 model page for the studio listing.
The model is the same. The bill is not. Hedra's all-models catalog lists GPT Image 2 from 3.57 cents per generation. Elyum lists 6 credits ($0.06), charged only when you keep a take. Hedra's pricing page says monthly credits expire and do not roll over. Elyum pricing is Free (up to 150 credits once (our algorithm may grant them)), Plus $9/mo, Pro $29/mo, Ultra $69/mo; Hedra Basic is $15/mo (1,500 credits). Hedra's exact refund terms for a bad still were not confirmed; Trustpilot reviewers report charges on artifacted video. We never charge a failed generation.
Hedra is cheaper on a keep-everything pass. 3.57 cents vs $0.06 is real. Elyum is cheaper when you discard. Ten renders and three keeps cost 3 × 6.4 = 6 credits ($0.06) here; ten billed generations on Hedra at 3.57 cents would be 35.7 cents if every job is charged. Hedra also ships Character-3 talking avatars and a wider video catalog. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed.

GPT Image 2 on Hedra
Hedra lists GPT Image 2 from 3.57 cents per generation on its all-models catalog. Hedra does not publish which subscription plan is required to run it, or a cents-per-credit rate. Paid plans (Basic $15/mo for 1,500 credits, Creator $30/mo for 5,400, Professional and Teams $75/mo for 14,400) all list commercial use; paid output is not watermarked. Free tier is 100 one-time credits; third-party reviews say free output is watermarked and not licensed for commercial use (not independently confirmed on Hedra's own free-tier copy).
Hedra has a documented Generation History & Credit Refunds page, but the exact terms were not independently fetched. A Trustpilot reviewer wrote that credits were charged even when the resulting video had visible artifacts, and refund requests went unanswered for a long time. That complaint is about video, not a confirmed GPT Image 2 still policy. Treat a bad Hedra render as billed unless support reverses it. Hedra also exposes a public API v3 and an MCP server, with pay-per-use pricing separate from subscription credits.
GPT Image 2 on Elyum
On Elyum, GPT Image 2 is 6 credits per render ($0.06). That is the keep price. Every render comes back as a free preview. You judge it, then keep the takes you want (credits leave the balance then) or kill the rest (full refund). Failed generations are never charged. Kills are metered on Free (one kill a month); paid plans kill freely. Kept files download clean, full quality, no watermark, commercial use included. Capabilities are text to image and image editing, with five aspect ratios. The GPT Image 2 listing is the source of those numbers.
Plans: Free up to 150 credits once (our algorithm may grant them) (no card), Plus $9/mo, Pro $29/mo, Ultra $69/mo; credits can be topped up. Pro and Ultra include fair-use unlimited image generation on selected image models. Do not assume GPT Image 2 is on that unlimited list unless the model page says so. You can also run it from Claude, ChatGPT, and Cursor via Elyum's MCP docs and the REST API. The catalog sits on the models index.

Where the two differ
Hedra lists GPT Image 2 from 3.57 cents per generation. Elyum bills 6 credits ($0.06) only on a keep. Hedra does not publish cents per credit. Monthly Hedra credits expire at cycle end; add-on packs are reported to persist.
Elyum: preview is free, a kill refunds in full, a failed job never bills. Free plan gets one kill a month; paid plans kill freely. Hedra documents Generation History & Credit Refunds, but exact terms were not confirmed. Trustpilot reviewers report charges on artifacted video and slow refunds.
On Elyum, GPT Image 2 is text to image and image editing with five aspect ratios. Hedra does not publish a GPT Image 2 resolution or aspect-ratio list. Hedra max resolution otherwise varies by model (Nano Banana Pro native 4K; Character-3 defaults to 720p). Do not assume those caps apply to GPT Image 2.
Both sides offer a public API and an MCP server. Hedra ships API v3 (typed async jobs, one key) with pay-per-use pricing separate from subscription credits. Elyum exposes a REST API and MCP for Claude, ChatGPT, and Cursor.
Hedra paid plans list commercial use and no watermark on paid files. Free-tier Hedra output is reported as watermarked and not commercially licensed (third-party; not confirmed on Hedra's own free-tier copy). Elyum kept takes are watermark-free with commercial use included.
Hedra centers on Character-3 plus ~46 video, ~35 image, and ~12 audio models. Elyum is 50+ models, one balance, and no timeline editor, stock, own avatars, mobile app, team seats, or feed. Hedra Trustpilot is ~2.1/5 on billing, not output. See the Hedra alternative page.
Pick Hedra when
- Listed GPT Image 2 price is lower: from 3.57 cents a generation vs Elyum's $0.06 on a keep.
- Same account covers Character-3 avatars plus a large third-party video and image catalog and API v3.
- Paid plans include commercial use and no watermark; Basic starts at $15/mo with 1,500 credits.
- Transparent per-generation API pricing on Hedra's all-models catalog if you already bill there.
Pick Elyum when
- You pay 6 credits ($0.06) only on a keep. Kills refund in full. Failed jobs never bill.
- Free plan is up to 150 credits once (our algorithm may grant them), no card. That is enough for 23 kept GPT Image 2 stills (23 × 6.4 = 147.2).
- Kept downloads are clean, full quality, no watermark, commercial use included.
- Iterate cheaply: ten previews and three keeps cost $0.192 here vs 35.7 cents on Hedra if all ten bill.

Getting the most out of GPT Image 2
- Spell every on-image string in quotes and name the language (English, Japanese, Korean, Chinese, Hindi, or Bengali). GPT Image 2 is built for readable type; vague 'add a headline' is how you get a near-miss.
- For posters, menus, UI, and infographics, describe the grid: columns, margins, type sizes, and what must not wrap. OpenAI called out small text, iconography, and dense layouts as the usual failure points it holds. Give those jobs a structure.
- When editing, attach the source and name what stays. Say 'keep the logo, product, and camera; replace only the price and the subhead.' The model is an editor on Elyum as well as a generator.
- Pick one of Elyum's five aspect ratios to match the job before you prompt. Asking for a landscape web ad inside a portrait frame is how type gets crushed or reflowed.
- If you want a photograph, manga panel, or pixel-art still, name the medium and the camera or craft constraints (focal length, panel gutters, palette, pixel scale). OpenAI says those looks hold. 'Make it cinematic' without a lens or medium is a weak ask.
- Avoid stuffing three layouts into one prompt. One menu, one comic page, or one UI screen per take. Then kill the misses. Hedra bills the generation; Elyum bills the keep.
