IN-DEPTH ANALYSIS
GPT-4.1 vs Mistral Large 2: Detailed Comparison
GPT-4.1 is OpenAI's mid-range-tier language model with a 1.0M-token context window, excelling at reasoning. Mistral Large 2 from Mistral is a mid-range-tier model supporting 128K tokens in context, with standout performance in data extraction.
This is a genuine tradeoff rather than a clear win. GPT-4.1 leads by 14 points on combined coding and reasoning, and charges 16% more per blended million tokens to do it. The margin is narrow enough that the answer depends on your workload: on tasks where the extra capability shows up, the premium pays for itself; on routine work it does not. GPT-4.1 is priced at $2.00/M input tokens and $8.00/M output tokens. Mistral Large 2 costs $2.00/M input and $6.00/M output.
In independent benchmark evaluations, GPT-4.1 leads with coding scores of 91/100 and reasoning scores of 93/100, compared to Mistral Large 2's 84/100 in coding and 86/100 in reasoning.
Capability breakdown
Across the five core benchmark categories, here is how GPT-4.1 and Mistral Large 2 stack up head to head:
Best model by task
- coding: GPT-4.1 wins with 91/100
- reasoning: GPT-4.1 wins with 93/100
- data extraction: GPT-4.1 wins with 92/100
- creative tasks: GPT-4.1 wins with 90/100
- vision/multimodal: GPT-4.1 wins with 91/100
Estimated monthly cost at scale
At 10M + 2M per month, GPT-4.1 runs about $36.00 while Mistral Large 2 runs about $32.00 — Mistral Large 2 saves roughly $4.00 (11%) every month.
What actually decides it
GPT-4.1 and Mistral Large 2 come from different labs, which means different tokenizers, different API shapes, and a second vendor relationship. The same English text does not produce the same token count on both, so a price-per-million comparison understates the difference — measure your own prompts on each before treating the headline rates as the full story.
GPT-4.1 and Mistral Large 2 were released within 9 months of each other, so they are competing on the same evaluations under roughly the same conditions. That makes a direct benchmark comparison meaningful here in a way it usually is not — neither model has the advantage of being measured on a newer, easier set of tests.
The context gap is the largest single difference on this pair: GPT-4.1 takes 1.0M tokens against 128K for Mistral Large 2, roughly 7.8x. That is the difference between feeding in a whole repository or a full contract set and having to chunk it. If your work involves documents you cannot split cleanly, this decides it on its own.
Throughput is close enough to ignore — 88/100 versus 82/100. Neither model will feel noticeably quicker in an interactive product, so latency is not a reason to choose between them.
One practical asymmetry: GPT-4.1 offers a batch API at 50% off standard rates, and Mistral Large 2 does not. For anything that does not need an answer immediately — nightly enrichment, backfills, evaluation runs — that discount can be worth more than the difference in list price, and it is easy to overlook when comparing headline rates.
Neither model is the obvious answer. GPT-4.1 leads on benchmarks, Mistral Large 2 on cost, and the gap is small on both. Run the calculator above with your real token mix — for most workloads that decides it faster than any benchmark table will.

What Is a Token?
Models don't read words — they process tokens.
A token is roughly 4 characters of English text (~¾ of a word). Your API bill is priced per million tokens — understanding this directly reduces your costs.
