# SPEC-004 — Image generation
|
|
|
|
Generation on `image-model` (default `gpt-image-2`), base64 end to
|
|
end — no URL downloads, no expiring CDN links in the generation path.
|
|
Optional knobs: `image-size` (default 1024x1024), `image-quality`
|
|
(passed through only when set). The Leonardo path stays behind
|
|
`leonardo-token` until parity is confirmed, then dies. The input
|
|
pipeline (attachment cache, vision, edit/remix) is FDB-010 / IMG-10+.
|
|
|
|
### IMG-01 — Images arrive as base64 buffers (coverage: test)
|
|
|
|
`draw_openai(description, count)` requests `count` images and returns
|
|
a list of decoded image buffers straight from the API response; every
|
|
generated image is metered in the ledger (SAF-05).
|
|
|
|
### IMG-02 — The envelope carries picture_count (coverage: test)
|
|
|
|
The envelope gains `picture_count` (integer). `post_process` clamps
|
|
it to 1..4 and defaults to 1 when absent (legacy history entries,
|
|
old-model output). ENV-19's field list is revised accordingly.
|
|
|
|
### IMG-03 — Multiple images, one message (coverage: test)
|
|
|
|
`picture_count` images are attached as multiple files to a single
|
|
Discord send (the last part when the answer is split, per BEH-06).
|
|
|
|
### IMG-04 — Legacy image models degrade safely (coverage: test)
|
|
|
|
When `image-model` is not a `gpt-image-*` model (e.g. `dall-e-3`),
|
|
the count is clamped to 1 and `response_format="b64_json"` is
|
|
requested explicitly (gpt-image models return base64 natively and
|
|
reject the parameter).
|
|
|
|
### IMG-05 — Picture prompts go to the API untouched (coverage: test)
|
|
|
|
The translate-before-draw step is deleted: the model's picture prompt
|
|
reaches the image API verbatim (current image models handle
|
|
Norwegian/German natively). The `translate()` method and its
|
|
`fix-model` dependency are gone (closes D-009).
