feat: read per-model stop tokens from Ollama model card at runtime by LopezNuance · Pull Request #198 · Michael-A-Kuykendall/shimmy

LopezNuance · 2026-04-18T17:43:14Z

Reads each model's stop tokens from its Ollama model card (ollama show <model>) at load time and applies them during generation. Without this, Shimmy generates past a model's actual EOS tokens, producing trailing garbage for models whose GGUF doesn't advertise stop tokens the way llama.cpp expects.

What changes

New src/model_registry.rs — per-model registry of runtime config (stop tokens, template hints)
New src/model_manager.rs — loads and caches per-model metadata from Ollama cards
New src/main_integration.rs, src/preloading.rs — integration wiring for startup preload
src/openai_compat.rs — threads registered stop tokens into the sampler stop list for each request

Why

Observed in P0 baselines: exaone-deep:2.4b and cogito:3b kept generating after reaching their natural stop sequences, producing inner-monologue continuations that corrupted downstream scoring. Ollama's model cards explicitly list these tokens; Shimmy just needs to read them.

Testing

Tested against exaone-deep:2.4b, cogito:3b, qwen3:8b — output now terminates at the same token positions Ollama produces.

GitHub Actions runners don't have NVIDIA CUDA toolkit installed, causing CMake configuration failures. Removed llama-cuda from Linux and Windows builds - they'll still have Vulkan and OpenCL GPU support. CUDA builds should be done locally or on CUDA-equipped CI systems.

GitHub runners lack system libraries for Vulkan/OpenCL. Building CPU-only binaries for faster compilation and broader compatibility. Users needing GPU support can compile locally with appropriate features. - Linux: CPU + vision - Windows: CPU + vision - macOS Intel: CPU + vision - macOS ARM64: CPU + MLX + vision (Apple Silicon GPUs supported)

…ry (Michael-A-Kuykendall#187) Fixes two bugs found during multi-round LLM deliberation experiments with qwen3:8b, cogito:8b, and gemma3:1b on Shimmy v1.9.0 GPU build. ## Fix 1 — n_ctx default 4096 → 8192 (issue Michael-A-Kuykendall#182) model_registry.rs (3 locations) and main.rs (5 locations) hardcode ctx_len=4096. With thinking models (qwen3, cogito, deepseek-r1) a single deliberation round exhausts the KV cache: system prompt (~80t) + task (~200t) + prior draft (~1610t) + transcript (~500t) + CoT chain (~1000t) + output (2048t) = 5438t > 4096 This causes NoKvCacheSlot errors that surface as HTTP 502 Bad Gateway. Fixed to 8192 in all six locations. A follow-up improvement would be to read context_length from the GGUF metadata via llama_model_meta_val_str so each model uses its own native default. Regression test: tests/regression/issue_182_kvcache_ctx_default.rs ## Fix 2 — UTF-8 token boundary crash (issue Michael-A-Kuykendall#183) engine/llama.rs generation loop called: token_to_str(token, Special::Plaintext)? token_to_str calls String::from_utf8(bytes)?. Byte-level tokenizers (qwen3, qwen2.5, deepseek, and most multilingual models) emit individual bytes as separate tokens — the character 你 (U+4F60) arrives as three consecutive tokens [0xE4, 0xBD, 0xA0]. from_utf8 on a single-byte token fails with FromUtf8Error, the ? propagates it, and the server returns 502. Fixed to: token_to_bytes(token, Special::Plaintext) .map(|b| String::from_utf8_lossy(&b).into_owned()) .unwrap_or_default() from_utf8_lossy accepts partial sequences; the complete character is reconstructed correctly as bytes accumulate across tokens.

…ichael-A-Kuykendall#188)

Instead of guessing stop tokens from hardcoded template families, query Ollama /api/show when a model is loaded and extract the stop tokens from the model card parameters. This handles gemma3 (<end_of_turn>), qwen3 (<|im_start|>, <|im_end|>), exaone ([|endofturn|]), and any future model automatically. Root cause of gemma3:1b premature EOS (62 chars vs 666 chars through Ollama): Shimmy had no stop tokens for gemma3 — fell through to OpenChat family which has empty stop_tokens. The model generated past its turn boundary without being stopped. Signed-off-by: Scott Johnson <rsjohnnson@gmail.com> Signed-off-by: scott <you@example.com>

LopezNuance · 2026-04-18T17:46:45Z

Context on where this came from: running symmetric-dialog evaluations against Shimmy with models like exaone-deep:2.4b and cogito:3b (both thinking-style models), the output would regularly continue past the model's natural stop sequence and produce a second, fragmented answer or trailing inner-monologue. The same models served via Ollama terminated cleanly. Diffing the two, Ollama reads the stop list from the GGUF's model card at load time; Shimmy didn't.

This PR wires that up. ModelRegistry holds the per-model stop tokens (loaded from the Ollama card at preload time), and openai_compat.rs threads them into the sampler's stop list for every request against that model.

Happy to scope this down further if you'd rather see the registry and the sampler wiring as separate PRs. The main_integration.rs / preloading.rs additions are fairly minimal and could also be folded into existing files if that's closer to the project's conventions.

Michael-A-Kuykendall · 2026-05-26T01:27:48Z

Hey, thank you for digging into this — the stop token gap you identified is real and affects a meaningful set of models. We've done a major architecture change for v2.0: llama.cpp has been fully removed and replaced with Airframe, our pure-Rust WebGPU inference engine. src/engine/llama.rs no longer exists.

The right fix for v2.0 is reading stop tokens directly from GGUF metadata fields (tokenizer.ggml.eos_token_id, tokenizer.ggml.eot_token_id, tokenizer.ggml.padding_token_id) rather than from ollama show, which introduces an Ollama runtime dependency we're trying to eliminate.

Your src/model_manager.rs and src/preloading.rs infrastructure is solid and we'd love to carry it forward. Would you be willing to revise this PR to:

Drop the src/engine/llama.rs changes (file deleted)
Replace the ollama show call with GGUF metadata reads from the already-loaded GgufFile struct
Rebase on current main

Happy to review quickly. The core work here is good and solves a real user-visible issue!!
