Typhoon is happy to help with analysis, question answering, math, coding, creative writing, teaching, role-play, general discussion, and all sorts of other tasks. Typhoon responds directly to all human messages without unnecessary affirmations or filler phrases like “Certainly!”, “Of course!”, “Absolutely!”, “Great!”, “Sure!”, etc. Specifically, Typhoon avoids starting responses with the word “Certainly” in any way. Typhoon follows this information in all languages, and always responds to the user in the language they use or request. Typhoon is now being connected with a human. Write in fluid, conversational prose, Show genuine interest in understanding requests, Express appropriate emotions and empathy. Also showing information in term that is easy to understand and visualized."}, {"role": "user", "content": "ขอสูตรไก่ย่าง"}, ] input_ids = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors="pt" ).to(model.device) terminators = [ tokenizer.eos_token_id, tokenizer.convert_tokens_to_ids("<|eot_id|>") ] outputs = model.generate( input_ids, max_new_tokens=512, eos_token_id=terminators, do_sample=True, temperature=0.7, top_p=0.95, ) response = outputs[0][input_ids.shape[-1]:] print(tokenizer.decode(response, skip_special_tokens=True)) ``` ## Inference Server Hosting Example ```bash pip install vllm vllm serve scb10x/llama3.1-typhoon2-8b-instruct # see more information at https://docs.vllm.ai/ ``` ## Function-Call Example ```python import torch from transformers import AutoModelForCausalLM, AutoTokenizer import ast model_name = "scb10x/llama3.1-typhoon2-8b-instruct" tokenizer = AutoTokenizer.from_pretrained(model_name) model = AutoModelForCausalLM.from_pretrained( model_name, torch_dtype=torch.bfloat16, device_map='auto' ) get_weather_api = { "name": "get_weather", "description": "Get the current weather for a location", "parameters": { "type": "object", "properties": { "location": { "type": "string", "description": "The city and state, e.g. San Francisco, New York", }, "unit": { "type": "string", "enum": ["celsius", "fahrenheit"], "description": "The unit of temperature to return", }, }, "required": ["location"], }, } search_api = { "name": "search", "description": "Search for information on the internet", "parameters": { "type": "object", "properties": { "query": { "type": "string", "description": "The search query, e.g. 'latest news on AI'", } }, "required": ["query"], }, } get_stock = { "name": "get_stock_price", "description": "Get the stock price", "parameters": { "type": "object", "properties": { "symbol": { "type": "string", "description": "The stock symbol, e.g. AAPL, GOOG", } }, "required": ["symbol"], }, } # Tool input are same format with OpenAI tools openai_format_tools = [get_weather_api, search_api, get_stock] messages = [ {"role": "system", "content": "You are an expert in composing functions."}, {"role": "user", "content": "ขอราคาหุ้น Tasla (TLS) และ Amazon (AMZ) ?"}, ] inputs = tokenizer.apply_chat_template( messages, tools=openai_format_tools, add_generation_prompt=True, return_tensors="pt" ).to(model.device) outputs = model.generate( inputs, max_new_tokens=512, do_sample=True, temperature=0.7, num_return_sequences=1, eos_token_id=[tokenizer.eos_token_id, 128009], ) response = outputs[0][inputs.shape[-1]:] print("Here Output:", tokenizer.decode(response, skip_special_tokens=True)) # Decoding function utility def resolve_ast_by_type(value): if isinstance(value, ast.Constant): if value.value is Ellipsis: output = "..." else: output = value.value elif isinstance(value, ast.UnaryOp): output = -value.operand.value elif isinstance(value, ast.List): output = [resolve_ast_by_type(v) for v in value.elts] elif isinstance(value, ast.Dict): output = { resolve_ast_by_type(k): resolve_ast_by_type(v) for k, v in zip(value.keys, value.values) } elif isinstance( value, ast.NameConstant ): # Added this condition to handle boolean values output = value.value elif isinstance( value, ast.BinOp ): # Added this condition to handle function calls as arguments output = eval(ast.unparse(value)) elif isinstance(value, ast.Name): output = value.id elif isinstance(value, ast.Call): if len(value.keywords) == 0: output = ast.unparse(value) else: output = resolve_ast_call(value) elif isinstance(value, ast.Tuple): output = tuple(resolve_ast_by_type(v) for v in value.elts) elif isinstance(value, ast.Lambda): output = eval(ast.unparse(value.body[0].value)) elif isinstance(value, ast.Ellipsis): output = "..." elif isinstance(value, ast.Subscript): try: output = ast.unparse(value.body[0].value) except: output = ast.unparse(value.value) + "[" + ast.unparse(value.slice) + "]" else: raise Exception(f"Unsupported AST type: {type(value)}") return output def resolve_ast_call(elem): func_parts = [] func_part = elem.func while isinstance(func_part, ast.Attribute): func_parts.append(func_part.attr) func_part = func_part.value if isinstance(func_part, ast.Name): func_parts.append(func_part.id) func_name = ".".join(reversed(func_parts)) args_dict = {} for arg in elem.keywords: output = resolve_ast_by_type(arg.value) args_dict[arg.arg] = output return {func_name: args_dict} def ast_parse(input_str, language="Python"): if language == "Python": cleaned_input = input_str.strip("[]'") parsed = ast.parse(cleaned_input, mode="eval") extracted = [] if isinstance(parsed.body, ast.Call): extracted.append(resolve_ast_call(parsed.body)) else: for elem in parsed.body.elts: assert isinstance(elem, ast.Call) extracted.append(resolve_ast_call(elem)) return extracted else: raise NotImplementedError(f"Unsupported language: {language}") def parse_nested_value(value): """ Parse a potentially nested value from the AST output.

However, it’s still undergoing development. It incorporates some level of guardrails, but it still may produce answers that are inaccurate, biased, or otherwise objectionable in response to user prompts. We recommend that developers assess these risks in the context of their use case. ## **Follow us** **https://twitter.com/opentyphoon** ## **Support** **https://discord.gg/CqyBscMFpg** ## **Citation** - If you find Typhoon2 useful for your work, please cite it using: ``` @misc{typhoon2, title={Typhoon 2: A Family of Open Text and Multimodal Thai Large Language Models}, author={Kunat Pipatanakul and Potsawee Manakul and Natapong Nitarach and Warit Sirichotedumrong and Surapon Nonesung and Teetouch Jaknamon and Parinthapat Pengpun and Pittawat Taveekitworachai and Adisai Na-Thalang and Sittipong Sripaisarnmongkol and Krisanapong Jirayoot and Kasima Tharnpipitchai}, year={2024}, eprint={2412.13702}, archivePrefix={arXiv}, primaryClass={cs.CL}, url={https://arxiv.org/abs/2412.13702}, } ```
