BIST Tool — Gemma 4 E2B

Fine-tuned Gemma 4 E2B for financial tool-calling (BIST / US / FX / crypto / funds-style tools).

Behavior

Intent Tools
Known ticker price (GARAN, THYAO, AAPL) get_quote
Research a known stock get_quote + get_profile + get_technical_analysis
Unknown name (EUREN) search_symbol (bist, us, fund, crypto) — not EUR/FX
Explicit FX (euro kuru, dolar kaç) get_quote with market: fx

Example (Gemma 4 tool tokens):

<|tool_call>call:get_quote{symbol:<|"|>THYAO<|"|>,market:<|"|>bist<|"|>}<tool_call|>

Usage

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

REPO = "HF_USER/bist-tool-gemma4-e2b"

tokenizer = AutoTokenizer.from_pretrained(REPO)
model = AutoModelForCausalLM.from_pretrained(
    REPO,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

Use the Gemma 4 chat template. Prefer thinking off for clean tool tokens.
If the host prefixes tool names (mcp__…__get_quote), map them to short labels (get_quote, search_symbol, …).
