Pricing tiers

GLM 5.3 Flash: $0.15/$0.50 per MTok on Z.ai's first-party API (cached input $0.03); third-party hosts (GMI, Novita, Together) list the same $0.15/$0.50. No promo tier is listed. The faster GLM-5.3-FlashX costs $0.37/$1.25.

MiniMax M2.5: $0.30/$1.20 per MTok on MiniMax's pay-as-you-go API (cache read $0.03). MiniMax lists M2.5 as a legacy model. Open weights (community license).

GLM 5.3 Flash

GLM 5.3 Flash is Z.ai's natively multimodal open-weight workhorse — 1M context, hybrid sparse/linear attention, near-flagship Intelligence Index at a fraction of the cost.

Best for

  • Cost-efficient long-context
  • Multimodal input
  • Coding agents

Watch out

Self-hosting needs ~186GB GPU memory at 4-bit (multi-GPU). Third-party hosts charge more than Z.ai's own API.

MiniMax M2.5

MiniMax M2.5 is a legacy open-weight MiniMax MoE with a 204,800-token context.

Best for

  • Open-weight deployments
  • Multimodal

Watch out

Legacy: MiniMax's current models are M3 (1M context, multimodal) and M2.7 at the same $0.30/$1.20 price.

When the cheaper one wins

GLM 5.3 Flash is cheaper on output at $0.50 per million tokens against $1.20 for MiniMax M2.5 — about 2.4×. Use the cheaper tier for classification, extraction, summarisation, and any task where the expensive model’s extra score does not change the accepted output. The expensive one only pays if your hardest task actually fails on the cheap tier. These are standard-tier API rates, excluding batch and cache discounts.
