By price, Llama-3.3-70B-Instruct ranks 7th cheapest of 68 on input and 14th on output. Its quality score of 78 ranks 56th of 68, and on value (quality score ÷ output price) it ranks 14th of 68. Its blended rate sits 95% below the catalog average.

In real billing terms: a support chatbot handling 50,000 turns a month (2,000 input / 500 output tokens each) costs about $18 per month on Llama-3.3-70B-Instruct, while a RAG workload of 20,000 queries (8,000 input / 800 output tokens each) runs about $21. Because output is priced 3.2× input here, long-generation tasks scale cost fastest — cap output length before you optimise anything else.

A 128K context window holds roughly 171 pages of A4 text (at ~750 tokens per page), ranking 53rd of 68 here. That covers typical RAG and multi-turn chat, though book-length inputs still need retrieval and chunking. Output runs at about 100 tok/s (30th fastest of 68), acceptable interactively, though long responses will feel slow.

We track 4 Microsoft models, and Llama-3.3-70B-Instruct's blended rate sits 40% above that provider's average. If your task tolerates a little less headroom, qwen3.5-flash (Alibaba) blends about 65% cheaper at a quality score of 82, and is worth benchmarking first. Going the other way, Hunyuan HY3 scores 87 on quality for about 36% less.

The closest model in Microsoft's line-up is MAI-DS-R1 ($0.14 input / $0.28 output, quality 90). Against it, Llama-3.3-70B-Instruct scores 12 points lower on quality, runs 40 tok/s faster (about 67%), costs 13% less blended. When two models sit this close on price, the deciding factor is usually the quality ceiling — run both against your real prompts before picking.

Modalities

Text

Where it fits — and where it doesn't

Good fit

  • Coding: writing, refactoring and debugging across multi-file project context.
  • Chat and support: natural multi-turn conversation for user-facing products.
  • High-volume, cost-sensitive batch work: low rates suit classification, tagging and summarization at scale.

Poor fit

  • Hard reasoning: a quality score of 78 is on the low side here; pick a stronger model for complex planning or maths.
  • Image understanding: this model is text-only, so vision tasks need a multimodal alternative.
