Per review: upscaling should be the default behavior (like the original
flux-2-pro chain), not agent opt-in. Policy: every image model whose
native output is below ~2MP now sets upscale=True in its catalog —
users never silently get low-res images. Native hi-res models
(Seedream 5 Pro/Lite, Krea 2 Large) stay off to avoid paying to
upscale already-large output.
- FAL catalog: 16 models flipped to upscale=True (klein, z-image,
nano-banana pro/2/2-lite, gpt-image 1.5/2, ideogram v3/v4, recraft
v4/v4.1, qwen image/3, krea-2 medium on FAL, MAI 2.5 pro).
- Krea plugin: per-model upscale defaults (medium + medium-turbo ON at
1.5K native; large OFF at 2K native), precedence explicit kwarg >
image_gen.krea.upscale config > catalog default.
- The 'upscale' tool param remains as a per-call override in both
directions (false = fast draft, true = force on hi-res/edits).
- Video unchanged: opt-in only (default-on would double every video's
cost and latency).
- Sibling tests updated: routing/payload tests pass upscale=False where
the assertion targets the generation submit; catalog test now pins
the native-resolution policy instead of the flux-2-pro snapshot.
The generated-media surface previously had almost no upscaler coverage:
only fal-ai/flux-2-pro chained Clarity Upscaler (hardcoded catalog
default), every other image model returned ~1MP output with no high-res
path, and video had no upscaler at all. Krea's API treats the enhancer
as a standard second pass; this brings the same shape to Hermes.
- image_generate: new optional 'upscale' boolean in the tool schema.
Explicit true chains the backend upscaler on ANY model (including
edits); explicit false disables flux-2-pro's automatic default;
omitted keeps per-model catalog behavior. Response now reports
'upscaled' so the agent knows which resolution it got.
- FAL image path: explicit flag overrides the catalog 'upscale' default
(Clarity Upscaler, 2x). Failure falls back to the native image.
- Krea plugin: upscale=true chains Krea Enhance
(/generate/enhance/krea/enhance, 2x, prompt-guided) through the same
BYO/managed base URL + auth as generation, with a best-effort poll
loop that never fails a successful generation.
- video_generate: new optional 'upscale' boolean; FAL video plugin
chains ByteDance SeedVR2 (fal-ai/seedvr/upscale/video, 2x factor
mode). Providers without upscalers ignore the kwarg per the ABC
contract (documented in both ABCs).
Validation: targeted suites green (123 tests across 6 files, including
new coverage for override-wins/default-kept/failure-fallback on all
three paths); live E2E on direct FAL verified both chains end-to-end
(klein 9b + Clarity upscaled image; pixverse-v6 1s 360p + SeedVR2
upscaled video).
* feat(image_gen): add Krea provider plugin (Krea 2 Medium + Large)
New built-in image_gen backend wrapping Krea's Krea 2 foundation
image model family. Auto-discovered like the other image_gen plugins
and appears in 'hermes tools' → Image Generation → Krea.
Krea's API is asynchronous — submit returns a job_id, poll /jobs/{id}
until terminal. The provider hides that behind the synchronous
ImageGenProvider.generate() contract: submit, poll every 2s with
light backoff (max 5s), 3-minute ceiling matching Krea's hosted-tool
timeout. Result URL is materialised to $HERMES_HOME/cache/images/
to avoid CDN-expiry 404s downstream (same fix as xAI #26942).
Models:
- krea-2-medium (default — Krea's 'start here' recommendation)
- krea-2-large
Aspect ratios map landscape→16:9, square→1:1, portrait→9:16.
Resolution: 1K (Krea's only current option).
Kwarg passthrough: seed, creativity (raw/low/medium/high), styles,
image_style_references (capped 10), moodboards (capped 1) — matches
Krea's per-request limits. Unknown kwargs are ignored.
Config knobs (config.yaml):
image_gen.provider: krea
image_gen.krea.model: krea-2-medium | krea-2-large
image_gen.krea.creativity: raw | low | medium | high
Env overrides: KREA_API_KEY (required), KREA_IMAGE_MODEL.
KREA_API_KEY is registered in OPTIONAL_ENV_VARS so 'hermes setup'
prompts for it.
31 new tests; image_gen suite + picker + tools_config: 211/211.
* fix(image_gen/krea): address review feedback
- Update KREA_API_KEY setup URL to the canonical token-creation page
(https://www.krea.ai/app/api/tokens). The previous URL returned 404.
- Fail fast on non-retryable HTTP statuses during poll. The previous
loop retried every HTTPError for the full 180s deadline, so an auth
(401), billing (402), forbidden (403), or not-found (404) response
would make image_generate hang for three minutes. Only retry
transient statuses (408/409/425/429/5xx); surface everything else
immediately.
- Add 5 tests covering fail-fast on 401/403/404 and retry on 429/503.
* fix(krea): point users at the real API token dashboard URL
Three call sites linked users to dashboard pages that don't exist:
- hermes_cli/config.py: https://www.krea.ai/app/api/tokens
- plugins/image_gen/krea/__init__.py get_setup_schema: https://www.krea.ai/api-keys
- plugins/image_gen/krea/__init__.py auth_required error: https://www.krea.ai/api-keys
Per Krea's own docs (https://docs.krea.ai/developers/api-keys-and-billing),
the real dashboard URL is https://www.krea.ai/settings/api-tokens. All three
sites now point there.
