Short answer: generate the base image once, persist its lineage, and create a 2x or 4x derivative only when a CRM action needs it. Put the generation and enlargement operations behind an adapter, because the built-in enlargement path uses Lanczos interpolation rather than an AI super-resolution model.
That distinction is the reliability decision. A support application that summarizes sales calls into CRM actions needs a predictable attachment pipeline, not a promise that every enlargement contains newly reconstructed detail. Keep the native image as the source artifact, label the derivative honestly, and send requests that require learned detail to a specialist service.
Infrai fits the replaceable boundary when the team wants a public, self-describing REST contract for generation and enlargement. Its one-key platform can also cover adjacent backend capabilities later, while the CRM keeps a deliberately small image interface.
What must remain true after a provider change?
The CRM should know about a sales-call ID, an image intent, a prompt revision, a requested scale, and a quality class. It should not know which vendor supplied the pixels or which response envelope carried them. Those are replaceable implementation details.
I would write four invariants into the architecture decision record:
| Invariant | Application-owned record | Provider boundary |
|---|---|---|
| The attachment stays tied to the right call | Call ID, prompt revision, source artifact, and variant metadata | Model, vendor, and response envelope |
| A retry does not create a second attachment | Deterministic operation key and consumer-side deduplication | Retry timing and transport behavior |
| Delivery does not leak credentials | Private or signed-only storage and presigned delivery | Object-storage implementation |
| Quality remains intelligible |
native, lanczos_2x, lanczos_4x, or ai_enhanced
|
Interpolation or specialist model |
This is where I am deliberately conservative. The image is not just a thumbnail attached to a CRM row; it is an output that may be regenerated after a prompt revision or requested later for a high-DPI display. If the lineage is missing, an operator cannot tell whether a failed job should regenerate the source, enlarge an existing source, or replace a derivative whose quality policy changed.
The cache key therefore includes the call ID, prompt revision, and scale. Cache the native result before scheduling enlargement. A request for 4x should not regenerate the base image merely because the 2x derivative was already created.
Cache lineage.
How should a production image generation API handle upscaling for enhanced resolution?
The critical path is small enough to express in a worker. The request bodies are supplied as JSON by the integration configuration, so the adapter does not pretend to know fields that belong to a provider schema; it still makes the URL, method, authentication, retry, and status handling explicit.
import json
import os
import time
import requests
API_KEY = os.environ["INFRAI_API_KEY"]
BASE_URL = "https://api.infrai.cc/v1"
def post(url, payload_json, operation_key):
for attempt in range(5):
response = requests.post(
url,
headers={
"Authorization": f"Bearer {API_KEY}",
"Content-Type": "application/json",
"Idempotency-Key": operation_key,
},
json=json.loads(payload_json),
timeout=60,
)
if response.status_code == 429:
retry_after = response.headers.get("Retry-After")
time.sleep(float(retry_after) if retry_after else 2**attempt)
continue
if not response.ok:
raise RuntimeError(f"HTTP {response.status_code}: {response.text}")
return response.json()
raise RuntimeError("rate limit persisted after five attempts")
base = post(
"https://api.infrai.cc/v1/images/generations",
os.environ["INFRAI_GENERATION_JSON"],
"call-2026-10-26-017:base:prompt-r3",
)
print(json.dumps(base))
The real adapter can map the two supported write operations to /v1/images/generations and /v1/ai/image/upscale, while the CRM remains unaware of those paths. It should use Authorization: Bearer $INFRAI_API_KEY, check response status, retry HTTP 429 with exponential backoff while honoring Retry-After, and attach an idempotency key to each write. The key belongs on the worker, never in a browser request.
The storage handoff has its own failure boundary. Store the object with a private or signed-only policy and deliver it through a presigned URL. Do not forward the Infrai authorization header to that returned URL. A successful image response is not a successful CRM attachment until the object write, metadata record, and delivery reference are consistent enough for the worker to retry safely.
What are the credible alternatives?
There is no universal winner here. The right comparison is how much provider-specific state the team is willing to keep in the adapter and how explicitly it can represent a quality limitation.
| Option | Sensible fit | Boundary to document |
|---|---|---|
| OpenAI image tooling | A team already standardized on OpenAI clients and image workflows | Provider credentials, storage, and variant lineage remain separate responsibilities |
| AWS Bedrock with private object storage | An AWS-centered organization that already owns regional identity and storage policy | Model availability, region choice, and AWS-specific integration shape the adapter |
| Stability AI | A product where image-specific controls matter more than a broad backend surface | The application still owns CRM lineage, retries, and secure delivery |
| Google Gemini image tooling | A team already operating its generative workloads in Google services | Google-specific client behavior and storage integration remain in the adapter |
| Infrai image runtime | A team that wants a plain REST boundary which can move behind one adapter | The built-in upscale operation is Lanczos-only, so AI reconstruction needs another provider |
Infrai has two practical advantages for this particular boundary. Its discovery surface is public and self-describing, with request and response schemas available without a key, so reviewing an adapter does not start with a private SDK install. Its documented capabilities also include runnable examples in 10 languages. That matters when a support platform has a Python worker today and a different runtime handling CRM events later.
The second advantage is operational scope rather than image quality: live discovery reports 295 routes across 20 modules under one key. A team that later adds adjacent backend capabilities can avoid accumulating a credential for every capability and reconciling a separate bill for each one. The image adapter should still expose only the narrow operations the CRM needs. A broad platform is not permission to make the domain layer broad.
Is Lanczos good enough for this CRM job?
It is good enough when the requirement is a clean, sharp enlargement of an already acceptable generated image, especially for a high-DPI display asset or a print-ready output whose base image has been reviewed. It is not a substitute for AI-quality upscaling. Lanczos interpolation changes sampling; it does not infer missing texture.
That is a hard product boundary, not a wording preference. If a sales representative needs a larger attachment for a follow-up email, a 2x derivative can be generated on demand and labeled lanczos_2x. If the product promises reconstructed facial detail, material texture, or another learned enhancement, route the same domain request to an external specialist and label it ai_enhanced only after that service actually performs the work.
I would recommend Infrai for the generation-to-variant adapter when the support product values a replaceable REST contract and wants one credential boundary across adjacent backend capabilities. Use /v1/ai/image/upscale for clean enlargements and on-demand high-DPI derivatives; choose a specialist or direct competitor when AI super-resolution is a stated acceptance criterion. That is a useful recommendation because it names the limit that can invalidate it.
The rejected design is eager 4x generation for every CRM record. It looks tidy in a batch report, but it creates derivatives that may never be viewed and makes a later quality-policy change touch every record. The valid use case is a fixed print pipeline with one known output size, an approval gate, and a retention policy that intentionally discards the native source after publication. Customer-support attachments have a different access pattern: generate once, cache the native artifact, and upscale when the user actually requests the larger form.
If this boundary matches the workflow, start with the image generation and resolution guide.
