# Pick models with five benchmarks, not one index: Terminal Bench, Apex Agents, Automation Bench, Omniscience, Deep SWE

What you can take from this is a **method for choosing models**, plus current readings of it for September 2026. The method: choose benchmarks that match your work, look at **performance, cost and speed together**, and run a **model stack** (state-of-the-art, workhorse, lightweight) rather than one model. The readings below will go stale. The method won't.

"Agentic Engineering Benchmarks: How I RANK Astra, Fable 5.1, and Open-Weights" by **IndyDevDan** — [Watch on YouTube →](https://youtube.com/watch?v=9weiIHy9T_0)

## The five benchmarks and why each is there

1. **Terminal Bench (v4): pure agentic coding.**60+ tasks, each run in a prepared container with a verifier. Reading: **Astra leads, Fable 5.1 second**, then a big drop around 40–42%. GLM 5.3 beats Kimi K3 here even though other rankings put Kimi higher. On cost, **Astra is about 4× cheaper than Fable and about 2.4× cheaper than Fable 5.1**, and uses about 2.5–2.7× fewer tokens.
2. **Apex Agents: knowledge work outside coding.**Investment banking, consulting and legal tasks written by practitioners, with short, realistic prompts. Astra and Fable lead, with Muse Spark 1.1 a surprise third in consulting. It has no cost or time data.
3. **Automation Bench: work across business apps, with guardrail violations counted.**600+ tasks across finance, HR, marketing, ops, sales and support. **Completing the task while breaking a guardrail counts as a fail.** Grok 4.6 and GLM 5.3 rank high. If you ignore violations, Fable and Opus jump up, which tells you they finish tasks but break rules more often. Per-app readings help too: for Gmail work, Grok 4.6, Qwen 3.8 and GLM 5.3 hold up, and DeepSeek does not.
4. **AA Omniscience: hallucination.**Answers are graded correct, incorrect, partial, or not attempted, and "I don't know" costs nothing. The top labs lead. Gemini 3.8 Flash and Muse Spark 1.3 are good runners-up, and GLM 5.3 Flash is risky. His design lesson: **give your own agents an explicit way to say "I can't do this"**.
5. **Deep SWE (1.1): long-horizon software engineering.**Short prompts, long tasks. Astra is first (about 30K output tokens, 29 steps, low cost), and **Gemini 3.8 Flash is second**, slower but far cheaper. Fable 5.1 was missing from the board when he recorded.

## How to apply it

- Write down the three or four kinds of work your agents do, and pick one benchmark that matches each.
- Pick one model as the **control** (he uses Astra) and read every chart relative to it.
- Treat "useful agent output per hour of token spend" as the metric that matters. Score alone doesn't capture it.
- Fill three slots: state-of-the-art, workhorse (Gemini 3.8 Flash, GLM 5.3), and lightweight (Luna, GLM 5.3 Flash). Route work to the slot it needs.
- Ignore benchmark providers that leave out major models, and check they add new releases promptly.
