What it is

IDA Pro's auto-analysis is single-threaded. On a 34 MB il2cpp DLL that's minutes. spectrIDA splits the binary into N shards, runs them in parallel via idalib, merges into one .i64, then lets a fine-tuned 8B model name every function — all from one terminal UI with a cyberpunk theme and exactly the right amount of sarcasm.

It is not Ghidra. It does one annoying thing (slow analysis + naming) fast, and it's genuinely fun to use. 199 downloads speak for themselves.

No cloud. No telemetry. Runs entirely on your machine.

Features

• Parallel sharded analysis — splits into address-space shards, runs N idalib instances, merges into one .i64. Workers configurable via flag, config, or env var.
• AI function naming — fine-tuned Qwen3-8B runs locally via Ollama, streams names token-by-token. Press N. Watch it think. Name appears.
• Batch naming — B to name every sub_* function in the list. Walk away. Come back.
• Binary overview — press O or run spectrida overview file.i64. Model reads 120 sampled function names and tells you what the binary does, what its subsystems are, and anything security-relevant. Correctly identified a 153k-function IL2CPP runtime in 30 seconds.
• Call chain explorer — C shows callers and callees. The model uses these as context when naming — a function called by Player$$TakeDamage gets named better than one in isolation.
• Decompiler view — D toggles Hex-Rays pseudocode.
• Export — dump everything to JSON, CSV, IDA .idc script, or a symbols file. The .idc applies all AI-generated names back into any IDA install in one click.
• Programmatic API — from spectrida.api import open_i64. Drive everything from scripts, notebooks, or Claude Code without touching the TUI.
• Demo mode (spectrida --demo) — try the whole thing with zero setup. No IDA, no Ollama.
• A first-run wizard — helps you install Ollama + the model, detects your IDA install automatically, then never asks again.

Programmatic API

No TUI needed — drive spectrIDA from scripts, Claude Code, notebooks, whatever:

import asyncio
from spectrida.api import open_i64

async def main():
    async with open_i64("GameAssembly.i64") as db:

        # list all 153k functions
        funcs = await db.list_functions()

        # name one function — returns name + reasoning + confidence
        result = await db.name_function(0x10001000)
        print(result["new_name"])     # init_atexit_handler
        print(result["reasoning"])    # allocates array of 3 fn ptrs, calls _atexit...

        # batch name everything (with live progress)
        async def on_progress(done, total, r):
            print(f"  {done}/{total}  {r['old_name']} -> {r['new_name']}")

        await db.batch_name(limit=500, rename=True, progress_cb=on_progress)

        # ask what the binary does
        overview = await db.overview()
        print(overview)

        # export to IDA script
        await db.export("names.idc", fmt="idc", named_only=True)

asyncio.run(main())

The model

hf.co/gdfhhjk/spectrida-re-gguf — Qwen3-8B fine-tuned for reverse engineering.

Trained on:

• x86/x64 assembly → function name pairs with call-chain context
• Tool call traces from jtsylve/ida-mcp — headless IDA with idalib
• Extended context reasoning traces from a codebase context server

Training approach: neuron-targeted SFT + GRPO. Only the RE-relevant neurons are tuned — base Qwen3 knowledge stays intact, you just added a very specific skill on top.

Runs locally via Ollama. GGUF — works on CPU, GPU, or both.

Who is this for

You're reversing something. You have a binary with 150,000 functions. Maybe 2,000 have names from metadata. The other 148,000 are sub_XXXXXXXX. You want to find the network code. You can't grep for it because nothing has a name yet.

A human RE can name ~50-100 functions per hour if they're fast. At that rate, 150k functions = 3 years.

spectrIDA names them overnight. Not perfectly — maybe 70% accuracy on generic functions, much higher on patterns the model recognizes. But now instead of 148k sub_ functions you have network_send_packet, serialize_player_state, validate_checksum — and you know where to look.

It doesn't replace a skilled reverse engineer. It does the boring 80% so you can focus on the interesting 20%. It's the orientation layer.

Real use cases:

• Game modding — find the physics system in a 150k-function binary in minutes, not days
• Security research — malware triage, understand a binary's architecture quickly
• CTF — time pressure, need to know what you're looking at immediately
• Anyone who has stared at sub_140001234 for 20 minutes thinking there has to be a better way

What's coming (chapter 2)

• Deep context naming — follow call trees N levels deep, feed the full chain to the model. A function 3 hops from encrypt_block should know it's in the crypto path.
• Deobfuscation — TigressVM pattern detection and handler tracing
• MCP server — expose spectrIDA as an MCP tool so Claude Code can call it natively

MIT. Do whatever you want with it. If it works, cool. If it doesn't, blame the GGUF quantization.

Built with spite, coffee, and an RTX 4070. The model has 199 downloads with zero marketing. Each one adds 0.01% to development speed. (This is not true. But it's close.) 👻
