# Earnings Intelligence Copilot — Fine-tuned Phi-3.5-mini (Merged)
A QLoRA fine-tuned and merged version of Phi-3.5-mini-instruct for structured KPI extraction from SEC filings.
Part of the [Earnings Intelligence Copilot](https://github.com/ratnasekhar/earnings-copilot) — a multi-agent
system that ingests SEC filings, extracts KPIs, and generates citation-grounded investment memos.
## What it does
- Extracts financial KPIs (Revenue, Gross Margin, Operating Income, EPS, Free Cash Flow) from SEC filing chunks as structured JSON
- Returns `{"confidence": "UNVERIFIABLE"}` instead of hallucinating when data is not present
- Always includes a `source_quote` field grounding every answer in the original filing text
## Model Details
| Property | Value |
|---|---|
| Base model | microsoft/Phi-3.5-mini-instruct |
| Fine-tuning method | QLoRA (4-bit NF4 quantization) |
| LoRA rank | r=16, alpha=32 |
| Target modules | q_proj, v_proj, k_proj, o_proj |
| Training examples | 619 balanced examples (50% HIGH / 50% UNVERIFIABLE) |
| Data source | 10-K and 10-Q filings, 20 S&P 500 companies (2020-2024) |
| Training hardware | Kaggle T4 GPU (~75 minutes) |
| Model type | Full merged model (adapter + base combined) |
## Usage
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
tokenizer = AutoTokenizer.from_pretrained(
"ratnasekhar/earnings-copilot-phi3-merged",
trust_remote_code=True
)
model = AutoModelForCausalLM.from_pretrained(
"ratnasekhar/earnings-copilot-phi3-merged",
dtype=torch.float16,
device_map="auto",
trust_remote_code=True,
attn_implementation="eager"
)
model.eval()
chunk = "Net sales for Q1 FY2024 were $119.6 billion, an increase of 2% compared to Q1 FY2023."
prompt = (
"<|user|>\n"
"You are a financial KPI extraction model. Extract metrics as JSON. "
"Output {\"confidence\": \"UNVERIFIABLE\"} if not found. Never invent numbers.\n\n"
"Filing chunk:\n" + chunk + "\n\n"
"Extract: What was total revenue and its YoY change?<|end|>\n"
"<|assistant|>\n"
)
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
with torch.no_grad():
out = model.generate(
**inputs,
max_new_tokens=150,
do_sample=False,
pad_token_id=tokenizer.eos_token_id,
use_cache=False
)
print(tokenizer.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
```
## Example Outputs
**When data IS present:**
```json
{
"metric": "Total Revenue",
"value": "$119.6 billion",
"unit": "Billion",
"period": "Q1 FY2024",
"yoy_change": "+2%",
"source_quote": "Net sales for Q1 FY2024 were $119.6 billion",
"confidence": "HIGH"
}
```
**When data is NOT present:**
```json
{
"confidence": "UNVERIFIABLE",
"reason": "The chunk does not contain any specific revenue figures."
}
```
## Key Design Decision — Class Balance
Raw LLM-generated training data had 93% UNVERIFIABLE examples. Training on this
imbalanced data would cause the model to always refuse. We deliberately resampled
to 50/50 HIGH/UNVERIFIABLE to teach both behaviors equally — this is the core
fine-tuning contribution of the project.

class Phi3Config(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`Phi3Model`]. It is used to instantiate a Phi-3
model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
defaults will yield a similar configuration to that of the
[microsoft/Phi-3-mini-4k-instruct](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct).
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
documentation from [`PretrainedConfig`] for more information.
Args:
vocab_size (`int`, *optional*, defaults to 32064):
Vocabulary size of the Phi-3 model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`Phi3Model`].
hidden_size (`int`, *optional*, defaults to 3072):
Dimension of the hidden representations.
intermediate_size (`int`, *optional*, defaults to 8192):
Dimension of the MLP representations.
num_hidden_layers (`int`, *optional*, defaults to 32):
Number of hidden layers in the Transformer decoder.
num_attention_heads (`int`, *optional*, defaults to 32):
Number of attention heads for each attention layer in the Transformer decoder.
num_key_value_heads (`int`, *optional*):
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
by meanpooling all the original heads within that group. For more details checkout [this
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
`num_attention_heads`.
resid_pdrop (`float`, *optional*, defaults to 0.0):
Dropout probability for mlp outputs.
embd_pdrop (`int`, *optional*, defaults to 0.0):
The dropout ratio for the embeddings.
attention_dropout (`float`, *optional*, defaults to 0.0):
The dropout ratio after computing the attention scores.
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
The non-linear activation function (function or string) in the decoder.
max_position_embeddings (`int`, *optional*, defaults to 4096):
The maximum sequence length that this model might ever be used with.
original_max_position_embeddings (`int`, *optional*, defaults to 4096):
The maximum sequence length that this model was trained with. This is used to determine the size of the
original RoPE embeddings when using long scaling.
initializer_range (`float`, *optional*, defaults to 0.02):
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
rms_norm_eps (`float`, *optional*, defaults to 1e-05):
The epsilon value used for the RMSNorm.
use_cache (`bool`, *optional*, defaults to `True`):
Whether or not the model should return the last key/values attentions (not used by all models). Only
relevant if `config.is_decoder=True`. Whether to tie weight embeddings or not.
tie_word_embeddings (`bool`, *optional*, defaults to `False`):
Whether to tie weight embeddings
rope_theta (`float`, *optional*, defaults to 10000.0):
The base period of the RoPE embeddings.
rope_scaling (`dict`, *optional*):
The scaling strategy for the RoPE embeddings. If `None`, no scaling is applied. If a dictionary, it must
contain the following keys: `type`, `short_factor` and `long_factor`. The `type` must be `longrope` and
the `short_factor` and `long_factor` must be lists of numbers with the same length as the hidden size
divided by the number of attention heads divided by 2.
bos_token_id (`int`, *optional*, defaults to 1):
The id of the "beginning-of-sequence" token.
eos_token_id (`int`, *optional*, defaults to 32000):
The id of the "end-of-sequence" token.
pad_token_id (`int`, *optional*, defaults to 32000):
The id of the padding token.
sliding_window (`int`, *optional*):
Sliding window attention window size. If `None`, no sliding window is applied.
Example:
```python
>>> from transformers import Phi3Model, Phi3Config
>>> # Initializing a Phi-3 style configuration
>>> configuration = Phi3Config.from_pretrained("microsoft/Phi-3-mini-4k-instruct")
>>> # Initializing a model from the configuration
>>> model = Phi3Model(configuration)

"""
A simple example on using SFTTrainer and Accelerate to finetune Phi-3 models. For
a more advanced example, please follow HF alignment-handbook/scripts/run_sft.py.
This example has utilized DeepSpeed ZeRO3 offload to reduce the memory usage. The
script can be run on V100 or later generation GPUs. Here are some suggestions on
futher reducing memory consumption:
- reduce batch size
- decrease lora dimension
- restrict lora target modules
Please follow these steps to run the script:
1. Install dependencies:
conda install -c conda-forge accelerate
pip3 install -i https://pypi.org/simple/ bitsandbytes
pip3 install peft transformers trl datasets
pip3 install deepspeed
2. Setup accelerate and deepspeed config based on the machine used:
accelerate config
Here is a sample config for deepspeed zero3:
compute_environment: LOCAL_MACHINE
debug: false
deepspeed_config:
gradient_accumulation_steps: 1
offload_optimizer_device: none
offload_param_device: none
zero3_init_flag: true
zero3_save_16bit_model: true
zero_stage: 3
distributed_type: DEEPSPEED
downcast_bf16: 'no'
enable_cpu_affinity: false
machine_rank: 0
main_training_function: main
mixed_precision: bf16
num_machines: 1
num_processes: 4
rdzv_backend: static
same_network: true
tpu_env: []
tpu_use_cluster: false
tpu_use_sudo: false
use_cpu: false
3. check accelerate config:
accelerate env
4. Run the code:
accelerate launch sample_finetune.py
