# model-support-checker
|
||||
|
||||
Check whether a HuggingFace / ModelScope model is supported by **SGLang**,
|
||||
**vLLM**, or **vLLM-Ascend**, and since which version.
|
||||
|
||||
## Setup (one-time)
|
||||
|
||||
The tool is **stateful**: your access mode is persisted in `.state/state.json`
|
||||
(gitignored), so later runs need no flags or tokens.
|
||||
|
||||
On first run you choose between two access modes — **local clone is recommended**:
|
||||
|
||||
| | Local clone (recommended) | GitHub PAT |
|
||||
|---|---|---|
|
||||
| Result quality | Definitive (files grepped on disk) | Best-effort without token; code search 403s anonymously |
|
||||
| Rate limits | None | Yes — can break batch/version checks |
|
||||
| Repeat checks | Fast (disk reads) | Slower (GitHub API) |
|
||||
| Works offline | Yes, after initial clone | No |
|
||||
| Cost | ~1 GB+ disk (vLLM full history needed) | None |
|
||||
| Freshness | Stale until `git pull` | Always current |
|
||||
|
||||
```bash
|
||||
python3 main.py --setup local # clone all repos into .state/repos/
|
||||
python3 main.py --setup local --vllm-path P1 --sglang-path P2 --vllm-ascend-path P3 # reuse existing checkouts
|
||||
python3 main.py --setup token # GitHub API mode
|
||||
|
||||
python3 main.py --doctor # check setup state and local checkouts
|
||||
python3 main.py --reset-state # forget setup (cloned repos are kept and reused)
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
- Local clones are full clones (`--depth 1` breaks version detection).
|
||||
- The GitHub token is NEVER written to `.state/`; in token mode export
|
||||
`GITHUB_TOKEN` per run.
|
||||
- Re-run `--setup <mode>` anytime to switch modes; explicit `--vllm-path` /
|
||||
`--sglang-path` / `--vllm-ascend-path` / `--token` flags override the saved state for that run.
|
||||
- Each run in local mode refreshes checkouts in the background (`git fetch`)
|
||||
and reports staleness or failures at the end — never blocking the main
|
||||
check.
|
||||
|
||||
## Methodology
|
||||
|
||||
For each framework the checker runs four framework-agnostic steps:
|
||||
|
||||
1. **Architecture name** — read `architectures` from the model's `config.json`
|
||||
(HuggingFace first, ModelScope API as fallback). Can be overridden with
|
||||
`--arch` to skip the network lookup entirely.
|
||||
2. **Official docs** (supplementary) — grep the framework's supported-models page.
|
||||
3. **GitHub source** (authoritative) — search the framework's models directory on
|
||||
GitHub. All frameworks register a model by mapping the HF architecture
|
||||
string to a class in `<models_dir>/<file>.py`, so the architecture string is
|
||||
always present in its implementation file.
|
||||
- For vLLM this step additionally parses `registry.py` to extract the model
|
||||
category, module path, class name, and checks
|
||||
`_PREVIOUSLY_SUPPORTED_MODELS` / `_OOT_SUPPORTED_MODELS`.
|
||||
- For vLLM-Ascend this step parses `__init__.py` for `ModelRegistry.register_model()`
|
||||
calls to extract module and class.
|
||||
4. **Version** — determine the first framework release that contains the
|
||||
implementation (via the file's earliest commit date → nearest release).
|
||||
|
||||
The authoritative "is it supported" check uses the GitHub **code-search API**
|
||||
with a path filter on the models directory. Anonymous code search returns 403,
|
||||
so a `GITHUB_TOKEN` is required for a definitive answer. Without a token the
|
||||
tool falls back to scraping the models directory tree + grepping candidate files
|
||||
on the raw CDN; that fallback can be incomplete, so a NO without a token is not
|
||||
definitive. Step 4 also needs a token on rate-limited IPs.
|
||||
|
||||
### Local checkouts (no GitHub API)
|
||||
|
||||
Local mode is the recommended setup (`--setup local` clones all repos into
|
||||
`.state/repos/` automatically). All source reads (models directory,
|
||||
`registry.py`, and version history) are served from disk via `git`, and **no
|
||||
GitHub API requests are made** — only the architecture lookup (step 1) and the
|
||||
docs check (step 2) still touch the network.
|
||||
|
||||
```bash
|
||||
# Override saved paths for a single run (no GITHUB_TOKEN needed for source/registry/version)
|
||||
python3 main.py --framework vllm --vllm-path /path/to/vllm deepseek-ai/DeepSeek-V3
|
||||
python3 main.py --framework sglang --sglang-path /path/to/sglang Qwen/Qwen3.6-35B-A3B
|
||||
python3 main.py --framework vllm-ascend --vllm-ascend-path /path/to/vllm-ascend deepseek-ai/DeepSeek-V3
|
||||
```
|
||||
|
||||
`--vllm-ref` is ignored when `--vllm-path` is given. The local path must be a
|
||||
git checkout of the framework repo (so `git log`/`git tag` are available for
|
||||
version detection). Keep checkouts fresh with an occasional `git pull`.
|
||||
|
||||
No third-party dependencies — standard library only.
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
# After setup, just pass a model id
|
||||
python3 main.py --framework sglang Qwen/Qwen3.6-35B-A3B
|
||||
python3 main.py --framework vllm deepseek-ai/DeepSeek-V3
|
||||
python3 main.py --framework vllm-ascend deepseek-ai/DeepSeek-V3
|
||||
|
||||
# Check all frameworks at once (default)
|
||||
python3 main.py meta-llama/Llama-3.1-8B
|
||||
|
||||
# Token mode: GITHUB_TOKEN per run (never stored)
|
||||
GITHUB_TOKEN=xxx python3 main.py meta-llama/Llama-3.1-8B
|
||||
|
||||
# Manually specify architecture name (skip config.json fetch)
|
||||
python3 main.py --arch LlamaForCausalLM
|
||||
python3 main.py --framework vllm --arch DeepseekV3ForCausalLM
|
||||
python3 main.py --framework vllm --arch "DeepseekV3ForCausalLM,DeepseekV2ForCausalLM" some-org/some-model
|
||||
```
|
||||
|
||||
