Paid reasoning model for advanced coding, scientific reasoning, long-context analysis, agentic workflows, and multimodal understanding.
Agnes 2.5 Pro Alpha is currently listed from a single provider. Its official list price is $0.45 per 1M input tokens and $0.90 per 1M output tokens.
Artificial Analysis rates it 26.8 on the Intelligence Index, with 58.8 for coding. Against its lowest blended price of $0.563 per 1M, that is roughly 48 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 191 tokens per second, with 3.98s to the first token.
The context window is 1,000,000 tokens, with an output limit of 65,536 tokens. It supports reasoning, tool use, and structured output. Accepted input modalities are Text and Image. The weights are open, so it can also be self-hosted or served through a gateway of your choice.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Sorted by blended price (input×0.75 + output×0.25) asc. The official channel always shows regardless of rank. Whether a gateway's low price is actually usable can't be verified.
Interleaved thinking (reasoning between tool calls) is declared by 1 of 1 providers.
Price history accumulates from each data sync; currently only 1 sample(s) (2026-09-20). Each future sync adds a point, and once accumulated a line is drawn here.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
