Dimension-by-dimension analysis
Reasoning & overall intelligence
ERNIE 5.1 leads the overall aggregate by 2 points (66 vs 64). That is a meaningful, not marginal, edge on hard, multi-step reasoning, while MiniMax M2.7 remains a strong generalist that is not out of its depth on routine work.
Agentic coding
This is a modest gap: ERNIE 5.1 scores 62 against 59. On multi-file edits, SWE-style tickets and long-horizon agent loops ERNIE 5.1 needs fewer correction turns; MiniMax M2.7 is still competent for scripts and assisted completion but trails as task complexity rises.
Multimodal
ERNIE 5.1 leads multimodal 74 vs 62. A concrete modality difference: ERNIE 5.1 additionally handles image. Neither emits native video, so the comparison is about parsing images and documents, not generation.
Speed & latency
MiniMax M2.7 is faster in interactive use: ~70 tok/s with 0.4s TTFT versus ~45 tok/s with 0.7s TTFT (about 1.6× the throughput). For conversational UIs where perceived responsiveness drives retention, that edge is a real product factor even when raw reasoning is lower.
Context: window vs usable recall
Nominal windows are 128K for ERNIE 5.1 and 205K for MiniMax M2.7. Effective-context scores point the same way as window size — MiniMax M2.7 is ahead on usable recall (85 vs 82), so prefer it for long-document work where details cannot be missed.
Price & total cost
MiniMax M2.7 is the cheaper API at $0.27/$1.08 versus ERNIE 5.1 at $1.1/$3.3 per 1M input/output tokens — list input is about 4.1× lower.
Chinese vs English
English: ERNIE 5.1 65 vs MiniMax M2.7 65. Chinese: 92 vs 82. For Chinese-language production, ERNIE 5.1 is the stronger pick. Note that non-Chinese models generally require overseas network access for their APIs.
Tool use & ecosystem
Function-calling score: ERNIE 5.1 78 vs MiniMax M2.7 72, so ERNIE 5.1 has the edge on structured tool use. Fine-tuning is available from ERNIE 5.1 and MiniMax M2.7. Factor in existing SDK/plugin familiarity — switching cost often outweighs a few-point tool-use gap.
Cost worked example — same workload, real token math
Assume a production workload of 100M input + 30M output tokens per month, with 90% of input tokens served from cache. Figures use public list prices.
