deepseek-ai/DeepSeek-V4-Pro-0813
checkpoint on one 8×H200 node. It does not use the older preview weights and
does not treat the mutable hosted API ID deepseek-v4-pro as an artifact pin.
Recipe contract
DeepSeek’s repository has no Jinja chat template. Production serving depends on
the engine’s
deepseek_v4 tokenizer, reasoning, and tool parsers. Raw
Transformers loading is not an equivalent serving contract.
0. Set up your shell
Every command on this page is copy-paste. Paste this block once per terminal and replace only the API key; every later step reads these variables.Two keys, two jobs.
AIRESERVE_API_KEY authenticates you to AI Reserve
and creates the volume, quote, and instance. VLLM_API_KEY is a password you
invent for the vLLM server you are about to start: step 4 passes it as
vLLM’s --api-key, so the public HTTP port rejects anyone who does not
send it. No vendor issues it and AI Reserve never sees it.curl and jq; the Python tabs need
requests (python -m pip install requests).
Check stock first
A quote is free and creates nothing. Run one before creating storage, because the volume in step 1 is placed next to this hardware and fails the same way when none is in stock:availability and price means you can continue. An error
with code: no_capacity means this shape is not in stock in that region right
now: try another region here and in steps 1 and 2, or wait, and read
no_capacity reasons.
1. Allocate persistent storage
Available now. The accelerator hint places the volume in a data center where 8×H200 has stock today, so the instance in step 4 can mount it. If step 0 reported no stock, this call fails the same way.2. Quote the H200 node
Available now. Inspect the all-in hourly rate before launching. A quote expires after 120 seconds, so run step 4 right after it; if it has expired, run this step again.3. Download and verify the checkpoint
Manual today. AI Reserve has no managed preload job. Use the exact revision on a loader with the same persistent volume, or allow vLLM to populateHF_HOME on first launch. The verification command requires the current hf
CLI from huggingface_hub 1.18 or later, not the deprecated
huggingface-cli:
DeepSeek-V4-Pro preview,
DeepSeek-V4-Pro-DSpark, or an NVIDIA NVFP4 conversion. They are separate
artifacts with different draft modules and qualification requirements.
4. Launch vLLM
Available now, runtime qualification pending. DSpark is attached inside the 0813 checkpoint. Probabilistic draft sampling is the upstream recommendation for sampled chat; benchmark it against target-only serving before promotion.wait_for and
waitFor are already defined there):
/v1/models before the first request. To watch progress:
5. Verify reasoning and tools
SetENDPOINT from the HTTP connection for port 8000. Start with a small
output cap only in non-thinking mode; high and max reasoning may legitimately
need very large output budgets.
/v1/models is the
readiness signal; until then the port returns connection errors or 5xx:
low, high, and max; streaming; multi-turn; and tool-call tests.
DeepSeek wraps tool calls in its tagged DeepSeek markup language (DSML), which
the engine parser converts to OpenAI-shaped tool_calls. With tools, preserve
every prior reasoning_content value. Reject malformed tool markup at the
application boundary and retry with a bounded policy rather than executing
partially parsed arguments.
