04 — Questions

Which should you choose?

Which is better: GPT-4o mini, Llama-3.1-70B-Instruct or Llama-3.2-90B-Vision-Instruct?

GPT-4o mini is the better all-round choice, scoring 49/100 against Llama-3.2-90B-Vision-Instruct (44) and Llama-3.1-70B-Instruct (39). It leads on inputs & features. The score weighs capability 67%, inputs & features 20%, context window 13%.

Which is cheaper, GPT-4o mini, Llama-3.1-70B-Instruct or Llama-3.2-90B-Vision-Instruct?

GPT-4o mini is cheaper at $0.15 input / $0.60 output per million tokens (official OpenAI API price). Llama-3.1-70B-Instruct costs $0.72 input / $0.72 output per million tokens (median across 8 API providers). At a typical mix of three input tokens to one output token, that is $0.263 per million tokens for GPT-4o mini versus $0.72 for Llama-3.1-70B-Instruct (2.7× as much). Llama-3.2-90B-Vision-Instruct has no published per-token price.

Which scores higher on benchmarks?

GPT-4o mini scores higher on the Capabilities Index (ECI): GPT-4o mini 126.5 (#148 of 165), Llama-3.1-70B-Instruct 125.9 (#149 of 165) and Llama-3.2-90B-Vision-Instruct 125.5 (#150 of 165). The confidence ranges of the top two overlap (120.5–128.6 vs 120.8–128.2), so treat the gap as small. On individual benchmarks: GPQA Diamond — Llama-3.1-70B-Instruct 44.2%, Llama-3.2-90B-Vision-Instruct 41.0%, GPT-4o mini 37.7%; OTIS Mock AIME 2024–2025 — GPT-4o mini 6.9%, Llama-3.1-70B-Instruct 3.6%, Llama-3.2-90B-Vision-Instruct 2.6%.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-4o mini, Llama-3.1-70B-Instruct and Llama-3.2-90B-Vision-Instruct yet, so there is no like-for-like coding score. On overall capability, GPT-4o mini leads, which tends to carry over to coding, but test on your own codebase. All three support tool calling for agent workflows.

Which has the bigger context window?

GPT-4o mini, Llama-3.1-70B-Instruct and Llama-3.2-90B-Vision-Instruct share the same 128,000-token context window. Maximum output per response: GPT-4o mini up to 16,384, Llama-3.1-70B-Instruct up to 4,096, Llama-3.2-90B-Vision-Instruct up to 4,096 tokens.

Which can read images, PDFs, audio or video?

GPT-4o mini accepts text, images and PDFs; Llama-3.1-70B-Instruct accepts text; Llama-3.2-90B-Vision-Instruct accepts text and images. GPT-4o mini handles the widest range of inputs.

Are any of these open source?

Llama-3.1-70B-Instruct and Llama-3.2-90B-Vision-Instruct publishes its weights (Llama 3.2 Community License) and can be self-hosted; GPT-4o mini is proprietary.

Which is newer?

Llama-3.2-90B-Vision-Instruct is the newest, released Sep 25, 2024. Llama-3.1-70B-Instruct came out Jul 23, 2024; GPT-4o mini came out Jul 18, 2024. Knowledge cutoff: GPT-4o mini Sep 2023, Llama-3.1-70B-Instruct Dec 2023, Llama-3.2-90B-Vision-Instruct Dec 2023.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
