Source description

Meridian.AI — Continual-Learning Finance LLM

Meridian.AI is a finance-specialized language model that continuously fine-tunes a Qwen2.5-0.5B backbone every hour on 25+ finance and math datasets, using Elastic Weight Consolidation (EWC) to prevent catastrophic forgetting across training sessions. The entire pipeline runs unattended on free GitHub Actions infrastructure — no GPUs.

  • Base model: 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

Usage

The deployed checkpoint is a standard Qwen2 model — trust_remote_code=True is not required.

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.

Training data

A weighted streaming mix of 25+ finance and instruction datasets, including gbharti/finance-alpaca, sujet-ai/Sujet-Finance-Instruct-177k, nvidia/OpenMathInstruct-2, HuggingFaceFW/fineweb-edu, yahma/alpaca-cleaned, and the FinanceMTEB suite. See the repository README for the full curriculum and weights.
