Region Q1 Q2 North 120 180 South 95 61 West 210 205
## Key Findings * The North region saw the largest change in revenue between quarters, increasing by 60 (180 − 120 = 60). * Total revenue across all regions decreased slightly from 425 in Q1 to 446 in Q2 (120 + 95 + 210 = 425; 180 + 61 + 205 = 446; 446 − 425 = 21). * The West region maintained the highest revenue levels in both quarters, with 210 in Q1 and 205 in Q2. * The South region experienced the largest decrease in revenue, falling by 34 (95 − 61 = 34). ## Worth a Look * The South region's revenue dropped by more than one-third of its Q1 value, while other regions remained relatively stable.
## Key Findings - The North region recorded the largest change, with Q2 increasing by 60 over Q1 (180 − 120 = 60). - The South region experienced the largest decline, with Q2 dropping by 34 compared to Q1 (95 − 61 = 34). - West maintained the highest volume in both quarters, with its Q2 volume of 205 being 25 higher than North's Q2 volume of 180 (205 − 180 = 25). - Total volume across all regions in Q2 was 446 (180 + 61 + 205 = 446). - Total volume across all regions in Q1 was 425 (120 + 95 + 210 = 425).
## Key Findings - The largest increase in revenue occurred in the North region, growing from 120 to 180 (180 − 120 = 60). - The South region experienced a significant decrease in revenue, dropping from 95 to 61 (95 − 61 = 34). - The West region's revenue slightly decreased from 210 to 205 (210 − 205 = 5). ## Worth a Look - The South region's revenue in Q2 is notably low at 61, which is the lowest among all regions in both quarters.

- **[HIGH] SQL Injection** — The code concatenates user-supplied input (`user_id`) directly into a SQL query string. An attacker could provide a crafted `user_id` to execute arbitrary database commands (e.g., `1; DROP TABLE users;`). Always use parameterized queries (e.g., `db.execute("SELECT * FROM users WHERE id = ?", (user_id,))`) to ensure input is safely escaped.## Findings
- **HIGH SQL Injection** — The pattern `query = "SELECT * FROM users WHERE id = " + user_id` concatenates untrusted user input directly into a SQL query string, which allows an attacker to manipulate the query structure and execute arbitrary database commands. To fix this, use parameterized queries (prepared statements), for example: `db.execute("SELECT * FROM users WHERE id = %s", (user_id,))` (the exact placeholder syntax, such as `?` or `%s`, depends on your database library).## Findings - **[HIGH] SQL Injection** — Line 11 constructs a SQL query by directly concatenating user input (`user_id`), which can allow an attacker to manipulate the query and execute arbitrary SQL commands. This is risky as it can lead to data breaches or data loss. A concrete fix is to use parameterized queries or prepared statements to safely include user input in SQL queries, e.g., `query = "SELECT * FROM users WHERE id = ?"`, and then pass `user_id` as a parameter.

def run(cmd):
os.system("sh -c " + cmd)## Findings
- **[HIGH] Command Injection** — The `os.system("sh -c " + cmd)` line concatenates user-supplied input directly into a shell command, allowing for arbitrary code execution. Use `subprocess.run(["sh", "-c", cmd])` or, preferably, avoid shell execution by passing arguments as a list to `subprocess.run()` without `shell=True`.## Findings
- **[HIGH] Command Injection** — `os.system("sh -c " + cmd)` concatenates the input command directly into a shell execution string. If `cmd` contains untrusted user input, an attacker can append malicious shell metacharacters (such as `;`, `|`, or `&&`) to execute arbitrary commands on the host. To fix this, use the `subprocess` module with safe argument passing and `shell=False` (e.g., `subprocess.run(["executable", arg1, arg2], check=True)`), or strictly sanitize and whitelist inputs if shell execution is unavoidable.## Findings
- **[HIGH] Command Injection** — The line `os.system("sh -c " + cmd)` directly concatenates user input (`cmd`) into a shell command, which can lead to command injection vulnerabilities. An attacker could execute arbitrary commands on the system. To fix this, use a safer method such as `subprocess.run()` with a list of arguments, or validate and sanitize the input before execution.

What we learned
In our July 2026 two-model run, GPT-4o mini passed 56/58 cases while the larger GPT-4o passed 51/58 — instruction fidelity beat model size. Our latest three-model run (July 18, 2026) repeats the pattern at full-suite scale: GPT-4o mini passed 146/151 and Gemini 3.1 Flash-Lite 145/151 — a near tie, with the Gemini lite model answering almost twice as fast (~0.9s vs ~1.6s average). The bigger Gemini 3.5 Flash was both the slowest (~4.3s) and the lowest-scoring (142/151). On tightly-scoped clipboard transformations, bigger models don't buy accuracy — which is why Transfo's "Auto" setting defaults to each provider's economical tier.
A two-pass "Smart Context" pipeline matched single-pass quality (56/58 vs 57/58) but doubled latency (~2.7s vs ~1.4s) — so single-pass stays the default and the second pass powers Pro's opt-in Smart Refine instead.
Methodology
Each recipe has hand-written promptfoo test cases with deterministic assertions (format, structure, content checks) — no LLM-as-judge. Unit tests cover the app itself (licensing, providers, parsing). Bring-your-own-key means you can pick any supported model; these numbers exist so that choice is informed, not guesswork.
Next up: the same suite against Claude. Data updates land on this page as runs complete.
