Which should you choose?
Which is better: GPT-4o mini, Claude Haiku 3.5 or Llama-3.1-70B-Instruct?
It is close. Our weighted score puts them within a point (GPT-4o mini 50/100, Claude Haiku 3.5 49/100, Llama-3.1-70B-Instruct 40/100), so choose by what matters most for your work: Claude Haiku 3.5 for raw capability and GPT-4o mini on price. The score weighs capability 67%, inputs & features 20%, context window 13%.
Which is cheaper, GPT-4o mini, Claude Haiku 3.5 or Llama-3.1-70B-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 5 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). Claude Haiku 3.5 has no published per-token price.
Which scores higher on benchmarks?
Claude Haiku 3.5 scores higher on the Capabilities Index (ECI): Claude Haiku 3.5 127.2 (#134 of 148), GPT-4o mini 126.6 (#135 of 148) and Llama-3.1-70B-Instruct 125.9 (#136 of 148). The confidence ranges of the top two overlap (120.7–129.7 vs 120.5–128.5), so treat the gap as small. On individual benchmarks: GPQA Diamond — Llama-3.1-70B-Instruct 44.2%, Claude Haiku 3.5 38.1%, GPT-4o mini 37.7%; OTIS Mock AIME 2024–2025 — GPT-4o mini 6.9%, Claude Haiku 3.5 4.3%, Llama-3.1-70B-Instruct 3.6%.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-4o mini, Claude Haiku 3.5 and Llama-3.1-70B-Instruct yet, so there is no like-for-like coding score. On overall capability, Claude Haiku 3.5 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?
Claude Haiku 3.5 has the largest context window at 200,000 tokens, against 128,000 for GPT-4o mini and 128,000 for Llama-3.1-70B-Instruct. Maximum output per response: GPT-4o mini up to 16,384, Claude Haiku 3.5 up to 8,192, Llama-3.1-70B-Instruct up to 4,096 tokens.
Which can read images, PDFs, audio or video?
GPT-4o mini accepts text, images and PDFs; Claude Haiku 3.5 accepts text, images and PDFs; Llama-3.1-70B-Instruct accepts text. GPT-4o mini handles the widest range of inputs.

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 Oct 4, 2026.
