So werten wir

Weights tuned for rag (retrieval-augmented generation).

RAG workloads push enormous amounts of retrieved context through a model. The three things that matter: does it faithfully use what you retrieved (groundedness), does it degrade when the context is long (needle-in-a-haystack), and how much will a million input tokens cost you. Because RAG is input-heavy, the input price pillar gets a heavier weight than it does for agentic or generative workloads.

Field notes

Tipps für rag (retrieval-augmented generation)

  • 01

    A 1M+ token context window is usually overkill. Optimize retrieval quality first.

  • 02

    Prompt caching matters: pin the system prompt and retrieved context into the cache tier if available.

  • 03

    Use batch pricing for bulk backfills over your corpus.

As of April 2026, our weighted top 3 are R1 0528, Hunyuan A13B Instruct, DeepSeek V3.
Almost never. Most RAG systems send 10–50k tokens per query. A 200k context is plenty; a 1M context is a nice-to-have for edge cases.
A lot. If your retrieved context has repeating chunks — documentation, policy, FAQs — cached-input pricing can cut your bill by 70–80%.
For ambiguous queries, yes. For lookup-style queries, it just adds cost without improving grounding.
