The entire pipeline runs unattended on free GitHub Actions infrastructure — no GPUs. - **Base model:** [`Qwen/Qwen2.5-0.5B`](https://huggingface.co/Qwen/Qwen2.5-0.5B) (~494M params, Qwen2 architecture) - **Continual learning:** Elastic Weight Consolidation (diagonal Fisher) - **Training cadence:** hourly GitHub Actions CI on CPU runners - **Source code & full docs:** [github.com/MeridianAlgo/FinAI](https://github.com/MeridianAlgo/FinAI) ## Usage The deployed checkpoint is a **standard Qwen2 model** — `trust_remote_code=True` is **not** required. ```python import torch from transformers import AutoModelForCausalLM, AutoTokenizer repo_id = "meridianal/FinAI" tokenizer = AutoTokenizer.from_pretrained(repo_id, subfolder="checkpoint") model = AutoModelForCausalLM.from_pretrained( repo_id, subfolder="checkpoint", torch_dtype=torch.float32, low_cpu_mem_usage=True, ) model.eval() prompt = """### Instruction: Explain the difference between a bond's yield to maturity and its coupon rate. ### Response: """ inputs = tokenizer(prompt, return_tensors="pt") with torch.no_grad(): output = model.generate( **inputs, max_new_tokens=200, do_sample=True, temperature=0.8, top_p=0.92, repetition_penalty=1.3, no_repeat_ngram_size=3, pad_token_id=tokenizer.pad_token_id, eos_token_id=tokenizer.eos_token_id, ) print(tokenizer.decode(output[0], skip_special_tokens=True)) ``` Inputs are formatted with the `### Instruction: / ### Response:` template used during training. ## Model details | Specification | Value | |:---|:---| | Base model | Qwen2.5-0.5B | | Architecture | Qwen2ForCausalLM | | Parameters | ~494M | | Context window | 32,768 tokens (Qwen2.5 default) | | Training dtype | bfloat16 | | Continual learning | Elast...
