MiniMax-M3 vs GPT-5.6 Terra: which should you choose?

MiniMax-M3 — MiniMax multimodal model with an Intelligence Index of 44, a 1M-token context window and a blended price of $0.22/1M tokens (open weights).

GPT-5.6 Terra — OpenAI multimodal model with an Intelligence Index of 55, a 1M-token context window and a blended price of $1.14/1M tokens.

MiniMax-M3 vs GPT-5.6 Terra: GPT-5.6 Terra scores higher on the Intelligence Index. GPT-5.6 Terra leads overall capability (Intelligence Index 55.0 vs 44.0). MiniMax-M3 is the cheaper model to run at $0.22/1M blended tokens — about 5.2× cheaper.

Capability: intelligence, coding and agentic work

On the composite Intelligence Index the GPT-5.6 Terra scores 55.0 versus 44.0. For software development, the Coding Index puts GPT-5.6 Terra ahead (76.7 vs 58.6). On agentic, multi-step tool-use tasks, GPT-5.6 Terra measures stronger. Composite indices summarize many evaluations, but always test on your own workload before committing.

Context window and speed

The MiniMax-M3 accepts up to 1 million tokens per request, which sets how much documentation, transcript or code it can reason over at once. In measured throughput, GPT-5.6 Terra generates faster (138 vs 83 tokens/s), which matters for interactive apps and high-volume pipelines.

Pricing and access

At blended per-token rates, MiniMax-M3 is the cheaper model to run ($0.22 vs $1.14 per 1M tokens). MiniMax-M3 is open weights and GPT-5.6 Terra is proprietary api. Open-weight models can be self-hosted, trading per-call cost for infrastructure you manage; for production also weigh rate limits, throughput and data-residency requirements.

The verdict

Both are credible choices in the ai model comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology

Large language models are compared on independent leaderboard metrics: an Intelligence Index (a composite of reasoning and knowledge evaluations), Coding and Agentic indices where measured, community arena Elo, maximum context window, a blended API price per million tokens (weighted across cache-hit, input and output rates), and measured output speed in tokens per second. Where a model ships multiple reasoning-effort variants, we report its strongest variant. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit — and this space moves quickly, so figures reflect the leaderboard snapshot on the page date.
