Verdict

When to choose each

ERNIE 5.5 Flash Preview

Where it leads

  • Longer responses, up to 1,000,000 vs 128,000 output tokens
  • Cheaper cached input, $0.028 vs $0.03 per 1M tokens

Best for

  • Low-cost agents for spreadsheets, office documents and tool calls over MCP, where text input is enough
  • Long-horizon coding and game or 3D scene building inside an agent harness, at a Flash-tier price

Watch out for

  • A preview, served only through Baidu Qianfan: Baidu says the weights will be open-sourced under Apache 2.0 soon, but they are not out yet
  • Text only: it cannot read images, and in Baidu tests that needed vision a tool running Claude Opus 5.5 described the screen for it
  • In Baidu's own table it trails Hy4 on APEX-Agents 1.1 (64.2% against 75.0%) and DeepSeek-V4.1-Flash on DeepSWE v1.1 (71.2% against 77.0%), and stays far behind GPT-6.1 Sol and Claude Opus 5.5 on Terminal-Bench-Science 0.1 (21.0% against 57.0% and 63.3%)
  • Epoch AI and Arena have not scored it yet

GLM-5.3-Flash

Where it leads

  • Lower input and output prices, $0.15 and $0.50 vs $0.28 and $1.13 per 1M tokens
  • Accepts image and video input
  • Open weights you can run yourself

Best for

  • Low-cost coding from screenshots or screen recordings
  • Document and research agents on a budget

Watch out for

  • Thinking cannot be disabled
  • A faster GLM-5.3-FlashX is a separate model id at $0.37 input and $1.25 output per 1M tokens
