+# Working on the SGLang Backend
+
+The SGLang backend lives at `backend/python/sglang/backend.py` (async gRPC). It wraps SGLang's `Engine` (`sglang.srt.entrypoints.engine.Engine`) and translates LocalAI's gRPC `PredictOptions` into SGLang sampling params + outputs into `Reply.chat_deltas`. Structurally it mirrors `backend/python/vllm/backend.py` — keep them shaped the same so changes in one have an obvious analog in the other.
+
+## `engine_args` is the universal escape hatch
+
+A small fixed set of fields on `ModelOptions` is mapped to typed SGLang kwargs in `LoadModel` (model, quantization, load_format, gpu_memory_utilization → mem_fraction_static, trust_remote_code, enforce_eager → disable_cuda_graph, tensor_parallel_size → tp_size, max_model_len → context_length, dtype). **Everything else** flows through the `engine_args:` YAML map.
+
+Validation happens in `_apply_engine_args`. Keys are checked against `dataclasses.fields(ServerArgs)` (`sglang.srt.server_args.ServerArgs` is a flat `@dataclass` with ~380 fields). Unknown keys raise `ValueError` at LoadModel time with a `difflib.get_close_matches` suggestion — same shape as the vLLM backend.
+
+**Precedence:** typed `ModelOptions` fields populate `engine_kwargs` first, then `engine_args` overrides them. So a YAML that sets both `gpu_memory_utilization: 0.9` and `engine_args.mem_fraction_static: 0.5` ends up at `0.5`. Document this when answering "why didn't my YAML field stick?".
+
+**ServerArgs is flat.** Unlike vLLM, where speculative decoding is nested under `engine_args.speculative_config: {...}`, SGLang exposes flat top-level fields: `speculative_algorithm`, `speculative_draft_model_path`, `speculative_num_steps`, `speculative_eagle_topk`, `speculative_num_draft_tokens`, `speculative_dflash_block_size`, etc. There is no `speculative_config:` dict. Same goes for compilation, kv-transfer, attention — all flat.
+
+The canonical reference is `python/sglang/srt/server_args.py:ServerArgs` (line ~304). When SGLang adds new flags, no LocalAI code change is needed — they're automatically available via `engine_args:`. The validator picks them up because it introspects the live dataclass.
+
+## Speculative decoding cheatsheet
+
+`--speculative-algorithm` accepts `EAGLE`, `EAGLE3`, `NEXTN`, `STANDALONE`, `NGRAM`, `DFLASH`. `NEXTN` is silently rewritten to `EAGLE` in `ServerArgs.__post_init__` (`server_args.py:3286-3287`). MTP (Multi-Token Prediction) is the same EAGLE path with `num_steps=1, eagle_topk=1, num_draft_tokens=2` against a target whose architecture has multi-token heads (e.g. MiMo-7B-RL, DeepSeek-V3-MTP).
+
+| Algorithm | Drafter requirement | Gallery demo target | Gallery demo drafter |
+|-----------|--------------------|---------------------|----------------------|
+| `NEXTN` / `EAGLE` (MTP) | Assistant drafter or built-in heads | google/gemma-4-E2B-it, google/gemma-4-E4B-it | google/gemma-4-E2B-it-assistant, google/gemma-4-E4B-it-assistant |
+| `EAGLE3` | EAGLE3 draft head | (no gallery entry yet) | e.g. jamesliu1/sglang-EAGLE3-Llama-3.1-Instruct-8B |
+| `DFLASH` | Block-diffusion drafter | (no gallery entry yet) | e.g. z-lab/Qwen3-4B-DFlash-b16 |
+| `STANDALONE` | Smaller LLM as drafter | (no gallery entry yet) | any smaller chat-tuned LLM in the same family |
+| `NGRAM` | None — uses prefix history | (no gallery entry yet) | n/a |
+
+The Gemma 4 demos use `mem_fraction_static: 0.85` (cookbook default) and the cookbook's `num_steps=5, num_draft_tokens=6, eagle_topk=1` parameters. Other algorithms are reachable from any user YAML via `engine_args:` but don't have shipped demos yet — that's a deliberate gallery scope choice, not a backend limitation.
+
+Gemma 4 support requires sglang built from a commit that includes [PR #21952](https://github.com/sgl-project/sglang/pull/21952). LocalAI's pinned release for cublas12 / cublas13 includes it. The `l4t13` (JetPack 7 / sbsa cu130) build floors at `sglang>=0.5.0` because the `pypi.jetson-ai-lab.io` mirror still ships only `0.5.1.post2` as of 2026-05-06 — Gemma 4 / MTP recipes are therefore not available on l4t13 until that mirror catches up. `backend.py` keeps backward compat with the 0.5.x → 0.5.11 `SamplingParams.seed` → `sampling_seed` rename via runtime detection.
+
+Compatibility caveats per the SGLang docs: DFLASH and NGRAM are incompatible with `enable_dp_attention`; DFLASH requires `pp_size == 1`; STANDALONE is incompatible with `enable_dp_attention`; NGRAM is CUDA-only and disables the overlap scheduler.
+
+### `mem_fraction_static` + quantization + MTP on consumer GPUs
+
+When combining online weight quantization (`engine_args.quantization: fp8` / `awq` / etc.) with built-in-head MTP (`speculative_algorithm: EAGLE`/`NEXTN`) on a tight VRAM budget, sglang's default `mem_fraction_static: 0.85` will OOM during draft-worker init. The reason: sglang quantizes the **target** model's transformer blocks but loads the **MTP draft worker's vocab embedding** at the source dtype (typically bf16). For a 7 B-class model with a 150k-token vocab × 4096 hidden, that's another ~1.2 GiB allocated *after* the static pool is reserved. At 0.85 fraction on a 16 GB card there's no room left.
+
+Workaround: drop `mem_fraction_static` to ~0.7 so the post-static heap can absorb the MTP embedding alloc + CUDA graph private pools. Verified end-to-end on MiMo-7B-RL + fp8 + MTP on a 16 GB RTX 5070 Ti (`gallery/sglang-mimo-7b-mtp.yaml`) at ~88 tok/s. Models with larger vocabs or more MTP layers (e.g. DeepSeek-V3-MTP) need an even smaller fraction.
+
+This isn't documented anywhere upstream as of 2026-05-06 — the SGLang Gemma 4 cookbook uses 0.85 because their MTP path doesn't go through `eagle_worker_v2.py` for an embedding-bearing draft module. Don't blanket-apply 0.7 across all sglang YAMLs; only when MTP-with-built-in-heads + quantization combine.
+
+## Tool-call and reasoning parsers stay on `Options[]`
+
+ServerArgs has `tool_call_parser` and `reasoning_parser` fields, and the backend does pass them through to `Engine` so SGLang's own HTTP/OAI surface keeps working. But for the **LocalAI** request path the backend constructs fresh per-request parser instances in `_make_parsers` (`backend.py:286`) because the parsers are stateful — the streaming and non-streaming paths each need their own.
+
+So the user-facing knob stays on `Options[]`:
+
+```yaml
+options:
+  - tool_parser:hermes
+  - reasoning_parser:deepseek_r1
+```
+
+Putting these in `engine_args:` will set them on `ServerArgs` but the LocalAI-level streaming `ChatDelta` will not pick them up. Don't recommend that path.
+
+## What's missing today (out of scope, but worth tracking)
+
+- `core/config/hooks_sglang.go` — there is no SGLang equivalent of `hooks_vllm.go`. The vLLM hook auto-selects parsers for known model families from `parser_defaults.json` and seeds production engine_args defaults. A symmetric hook for SGLang could reuse the same `parser_defaults.json` (the SGLang parser names are different but the family detection is shared) and seed defaults like `enable_metrics: true` or attention-backend choices.
+- `core/gallery/importers/sglang.go` — vLLM has an importer that resolves model architecture → parser defaults at gallery-import time. A matching importer for SGLang would let `local-ai install` populate sensible parsers automatically.
+
+These should be a follow-up PR, not a blocker for the engine_args feature.

+### SGLang
+
+[SGLang](https://github.com/sgl-project/sglang) is a fast serving
+framework for LLMs and VLMs with a focus on prefix caching, speculative
+decoding, and multi-modal generation. LocalAI ships a gRPC backend that
+wraps SGLang's async `Engine`, including its native function-call and
+reasoning parsers.
+
+#### Setup
+
+```yaml
+name: sglang
+backend: sglang
+parameters:
+  model: "Qwen/Qwen3-4B"
+template:
+  use_tokenizer_template: true
+```
+
+The backend will pull the model from HuggingFace on first load.
+
+#### Passing arbitrary SGLang options with `engine_args`
+
+The same `engine_args:` map that the vLLM backend accepts is also
+honoured by the SGLang backend. Keys are validated against
+[`ServerArgs`](https://github.com/sgl-project/sglang/blob/main/python/sglang/srt/server_args.py)
+— SGLang's central configuration dataclass — and forwarded verbatim to
+`Engine(**kwargs)`. Unknown keys fail at load time with the closest
+valid name as a hint. Unlike vLLM, `ServerArgs` is flat: speculative
+decoding fields are top-level (`speculative_algorithm`,
+`speculative_draft_model_path`, etc.) rather than nested under a
+`speculative_config:` dict.
+
+The typed YAML fields shared with vLLM are mapped to their SGLang
+equivalents (`gpu_memory_utilization` → `mem_fraction_static`,
+`enforce_eager` → `disable_cuda_graph`, `tensor_parallel_size` →
+`tp_size`, `max_model_len` → `context_length`). Anything else,
+including all speculative-decoding flags, goes under `engine_args:`.
+
+##### Speculative decoding: Gemma 4 with Multi-Token Prediction
+
+Google publishes paired "assistant" drafters for every Gemma 4 size.
+The drafters use Multi-Token Prediction (MTP) to propose several
+candidate tokens per target step, which SGLang then verifies in
+parallel. Flags below are transcribed verbatim from the
+[SGLang Gemma 4 cookbook](https://docs.sglang.io/cookbook/autoregressive/Google/Gemma4#speculative-decoding-mtp-server-commands).
+
+For consumer GPUs in the 16–24 GB range, use **E4B** (8 B total /
+4 B effective parameters):
+
+```yaml
+name: gemma-4-e4b-mtp
+backend: sglang
+parameters:
+  model: google/gemma-4-E4B-it
+context_size: 4096
+template:
+  use_tokenizer_template: true
+options:
+  - tool_parser:gemma4
+  - reasoning_parser:gemma4
+engine_args:
+  mem_fraction_static: 0.85
+  speculative_algorithm: NEXTN
+  speculative_draft_model_path: google/gemma-4-E4B-it-assistant
+  speculative_num_steps: 5
+  speculative_num_draft_tokens: 6
+  speculative_eagle_topk: 1
+```
+
+For smaller cards (8–12 GB), drop to **E2B** (5 B total / 2 B effective)
+by swapping the model paths to `google/gemma-4-E2B-it` and
+`google/gemma-4-E2B-it-assistant`; the rest of the flags stay the same.
+
+`NEXTN` is normalised to `EAGLE` inside `ServerArgs.__post_init__`, so
+either value works — the cookbook uses `NEXTN`. `mem_fraction_static`
+is the share of GPU memory SGLang reserves for the model + KV pool;
+0.85 is the cookbook's default and adapts to whatever single GPU the
+backend is running on.
+
+The 31 B dense and 26 B-A4B MoE Gemma 4 variants exist in the same
+cookbook but require `--tp-size 2`, so they're not in the gallery as
+single-GPU recipes.
+
+> **SGLang version requirement.** Gemma 4 support landed in SGLang via
+> [PR #21952](https://github.com/sgl-project/sglang/pull/21952). The
+> LocalAI sglang backend pins a release that includes it; if you've
+> overridden the pin to an older version, this recipe will fail with a
+> "model architecture not recognised" error at load time.
+
+##### Other speculative algorithms
+
+`speculative_algorithm:` also accepts `EAGLE`/`EAGLE3` (paired with an
+EAGLE-style draft head), `DFLASH` (block-diffusion drafters from
+[z-lab](https://huggingface.co/z-lab) for the Qwen3 family), `STANDALONE`
+(a smaller draft LLM verifying a larger target), and `NGRAM` (no draft
+model — pure prefix-history speculation). See SGLang's
+[speculative-decoding docs](https://docs.sglang.io/advanced_features/speculative_decoding.html)
+for the full algorithm matrix.
+
+#### Tool calling and reasoning parsers
+
+SGLang's native parsers stream `tool_calls` and `reasoning_content`
+inside `ChatDelta` — the LocalAI Python backend wires them up
+per-request rather than via `engine_args:`. Pick a parser by name:
+
+```yaml
+options:
+  - tool_parser:hermes
+  - reasoning_parser:deepseek_r1
+```
+
+The full list of registered parsers lives in `sglang.srt.function_call`
+and `sglang.srt.parser.reasoning_parser`.
