From 917786f43d0f29b7c77a0c56767c0fa4df68b1c5 Mon Sep 17 00:00:00 2001 From: Juk Armstrong <69222624+jukofyork@users.noreply.github.com> Date: Sun, 1 Dec 2024 22:09:49 +0000 Subject: [PATCH] Add `mistral-v1`, `mistral-v3`, `mistral-v3-tekken` and `mistral-v7` chat template types (#10572) * Templates: `mistral-v1`, `mistral-v2`, `mistral-v3`, `mistral-v3-tekken` * Changed system message logic and added tests for all 4 * Invalid `system_message` instead of `content` fixed * Removed tab-indented lines * Added template code and test for `mistral-v7` * Added all tests. Fixed bug with `tmpl == "llama2"` test. * Replaced tabs with spaces. * Removed `'mistral-v2'` option as no (open) models ever used it * Removed all references to 'v2' template from comments * Update llama.cpp Fixed `trim_assistant_message` bug --- src/llama.cpp | 108 ++++++++++++++++++++++++----------- tests/test-chat-template.cpp | 32 ++++++++++- 2 files changed, 105 insertions(+), 35 deletions(-) diff --git a/src/llama.cpp b/src/llama.cpp index 22b951ba2..6e9ba9727 100644 --- a/src/llama.cpp +++ b/src/llama.cpp @@ -21862,41 +21862,85 @@ static int32_t llama_chat_apply_template_internal( if (add_ass) { ss << "<|im_start|>assistant\n"; } - } else if (tmpl == "llama2" || tmpl == "mistral" || tmpl_contains("[INST]")) { - // llama2 template and its variants - // [variant] support system message - bool support_system_message = tmpl_contains("<>") || tmpl == "mistral"; - // [variant] space before + after response - bool space_around_response = tmpl_contains("' ' + eos_token"); - // [variant] add BOS inside history - bool add_bos_inside_history = tmpl_contains("bos_token + '[INST]"); - // [variant] trim spaces from the input message - bool strip_message = tmpl_contains("content.strip()"); - // construct the prompt - bool is_inside_turn = true; // skip BOS at the beginning - ss << "[INST] "; - for (auto message : chat) { - std::string content = strip_message ? trim(message->content) : message->content; - std::string role(message->role); - if (!is_inside_turn) { - is_inside_turn = true; - ss << (add_bos_inside_history ?
