Flash Rules for AI Coding Agents

Use the Flash CLI — Do Not Call Runpod REST or GraphQL Directly

For anything Flash supports, use the flash CLI. Do not generate curl, httpx, requests, or gql calls against api.runpod.io, api.runpod.ai, or *.runpod.net to build, deploy, list, scale, log, or invoke endpoints. The CLI handles auth, hashing, drift detection, manifest generation, and image selection. Direct API calls bypass all of that and will silently desync from Flash state.

If a Flash command does not exist for what the user is asking, surface that gap (flash <area> --help first), then ask before reaching for raw API calls. Raw Runpod SDK use (runpod.Endpoint(...)) is acceptable only for invoking already-deployed endpoints from non-Flash code — never for lifecycle operations.

Identity

Flash is a Python SDK for deploying AI workloads to Runpod GPUs. You write decorated Python functions, Flash handles infrastructure, scaling, and deployment.

Endpoint Patterns

Pattern A: Queue-based function endpoint

from runpod_flash import Endpoint, GpuType

@Endpoint(
    name="my-gpu-worker",
    gpu=GpuType.NVIDIA_GEFORCE_RTX_4090,
    workers=(0, 3),
    dependencies=["torch"],
)
async def process(input_data: dict) -> dict:
    import torch
    return {"gpu": torch.cuda.get_device_name(0)}

Pattern B: Load-balanced routes

from runpod_flash import Endpoint

api = Endpoint(name="my-api", cpu="cpu3c-1-2", workers=(1, 3))

@api.get("/health")
async def health():
    return {"status": "ok"}

@api.post("/compute")
async def compute(numbers: list[float]) -> dict:
    return {"sum": sum(numbers)}

Pattern C: Class-based worker (stateful)

from runpod_flash import Endpoint, GpuType

@Endpoint(
    name="my-model",
    gpu=GpuType.NVIDIA_GEFORCE_RTX_4090,
    workers=(1, 3),
    dependencies=["torch", "transformers"],
)
class MyModel:
    def __init__(self):
        import torch
        from transformers import pipeline
        self.pipe = pipeline("text-generation", device="cuda")

    async def generate(self, prompt: str) -> dict:
        return {"text": self.pipe(prompt)[0]["generated_text"]}

Pattern D: Pre-built container image (no decorated function)

For workloads that already serve HTTP — vLLM, TGI, ComfyUI, Ollama, custom images — provision the endpoint with an image= argument and call it as a client. No Python handler to write. Flash deploys the image and gives you HTTP + queue access to it.

from runpod_flash import Endpoint, GpuGroup

vllm = Endpoint(
    name="vllm",
    image="runpod/worker-v1-vllm:v2.18.1",
    gpu=GpuGroup.ADA_24,
    workers=(0, 3),
    env={"MODEL_NAME": "meta-llama/Llama-3.1-8B-Instruct"},
)

# QB-style — the Runpod vLLM worker speaks the queue protocol
result = await vllm.runsync({"input": {"prompt": "hello", "max_tokens": 64}})

# Or LB-style HTTP if you've routed through a load-balanced front
models = await vllm.get("/v1/models")

When to use this pattern: the upstream project already publishes a serving image and you don't need to add any Python logic on top. If you need pre/post-processing, wrap the call inside a Pattern A or B @Endpoint instead.

To attach to an already-deployed endpoint (no provisioning), pass id= instead of image=:

ep = Endpoint(id="abc123")
result = await ep.runsync({"prompt": "hello"})

Rules That Break If Violated

• import torch and heavy libraries INSIDE the function body, never at module level
• Declare runtime dependencies in @Endpoint(dependencies=[...]), not in pyproject.toml
• Endpoint functions can be sync (def) or async (async def). Use async when awaiting other endpoints or async I/O
• workers=N is shorthand for (0, N) — auto-scales from 0 (cold start on every burst). Use workers=(N, N) to pin a fixed count; workers=(1, N) to keep at least one warm worker
• workers=(min, max) is the explicit range form — prefer it when you care about cold-start behavior
• Class workers: model loading in __init__, request handling in instance methods
• Cross-worker calls use await — call @Endpoint-decorated functions as if local; Flash handles remote dispatch
• System-level packages (ffmpeg, libgl1) go in system_dependencies, not dependencies
• @Endpoint is the canonical decorator. @remote is the legacy alias
