MiniMax M3.1 Flash Review: Space Bunny, Pricing and 46 Tests

Space Bunny was an early MiniMax M3.1 Flash. Our 46 official-API attempts expose a low-effort money error, with default 20/20 and low 19/20 text results, latency and code checks.

Updated: 2026-10-20

Original testing and analysis by TOKRACE · Tested October 20, 2026.

Results: 20/20 text tasks at default, 19/20 at low

TOKRACE tested the released MiniMax-M3.1-Flash through the official MiniMax API on October 20, 2026: 40 text attempts and 6 coding attempts. Default effort (documented as max when omitted) passed 20/20 text tasks; low passed 19/20. Both modes passed all three coding tasks.

Median time to first answer content across 20 text tasks was 1.405 s at default and 1.089 s at low. These are one-window, single-attempt observations from a local client. A money calculation failed at low despite valid JSON; use deterministic validation for such workflows.

What was Space Bunny? The MiniMax identity timeline

MiniMax’s October 19 announcement identifies Space Bunny as an early version of M3.1 Flash. This establishes product lineage, not identical checkpoints or interchangeable scores.

DateIdentity and evidence
September 27TOKRACE tested stealth/space-bunny-alpha via OpenRouter, 15 text attempts at low effort
October 3Official MiniMax-M3.1-Flash-Preview: 15 text and 3 coding attempts
October 19M3.1 Flash released; Space Bunny identity disclosed
October 20This review: 46 new official-model attempts; old Space Bunny ID probe returned HTTP 404

Original Space Bunny report · Original Preview review. Historical results remain unchanged. The old anonymous endpoint returned No endpoints found for stealth/space-bunny-alpha. and has been retired from this site’s trial pool. That is an availability result, not a capability failure. The separate Preview ID still returned 200 in a same-day probe; this does not prove it is the released checkpoint.

Sources: release and model guide. MiniMax reports 73.7% on DeepSWE v1.1 and 61.7% on OSWorld V2. These are vendor-reported benchmarks, not TOKRACE results. We did not reproduce those benchmarks or test vision, desktop operation or million-token context.

Method and limits

We fixed 15 existing text tasks, five new edge cases and three JavaScript tasks before calling either mode. Each task ran once per mode, with alternating pair order. No failed-attempt retries or best-of selection were used. Edge cases cover shipping and discounts, an instruction embedded in source data, final event states, superseded evidence and nullable types.

Requests used https://api.minimax.io/v1/chat/completions, temperature 0, streaming, reasoning_split=true, a 2,048-token text limit and an 8,192-token coding limit; timeout 120 seconds. Default omitted reasoning_effort; low explicitly sent low. Text was checked against fixed answers/JSON, code against predetermined assertions in an isolated VM. All 26 coding checks per mode completed; the reported score unit is tasks.

First content measures request start to the first nonempty answer fragment; first reasoning is recorded separately. API completion tokens include reasoning. Calls originated on local macOS; egress and provider region were not verified. Cache, load and routing were uncontrolled. One attempt per task cannot establish reliability, an overall ranking or broad reasoning quality.

Small-function checks do not establish repository repair, tool-use or end-to-end agent success rates.

Retained failure: low missed the shipping charge

The prompt specified 19.90 × 3, plus 4.50 shipping, minus a 5.00 order discount. The correct total is 59.20, requiring {"totalCents":5920}. Low returned {"totalCents":5470}, 450 cents short and equal to merchandise minus discount. Default returned 5920.

Valid JSON did not make the answer correct. We neither inspect nor publish private reasoning; the missing-shipping description concerns the numeric output, not its internal cause. Inspect the original prompt and answer.

Reading Space Bunny and Preview history fairly

Only the original 15 tasks enter this historical table. The five new cases are excluded. Dates, routes, settings and upstream versions differ: this is not a controlled before/after experiment, and supports no release-versus-Space-Bunny speedup or regression claim. Download the Space Bunny report and Preview evidence.

List price, free routing and actual spending

The 46 formal evaluation requests have a list-price equivalent of approximately $0.004424, using reported cached tokens and token usage. Subscription credentials were used. This is not an invoice or measured incremental cash spend, and excludes connectivity probes and browser retests.

On October 20, OpenRouter’s released-model listing included minimax/minimax-m3.1-flash:free. It is a different route with changeable availability; the 46 tests did not use it. TOKRACE’s released-model trial uses the official MiniMax API and site quotas. Historical free pricing for the old anonymous ID does not apply to the official API.

Use the released model and reproduce a task

The released model page links to a trial. The rerun button below loads the first task; press Start to send it. Shared trials use default effort. To reproduce low effort, configure your own MiniMax key and these extra JSON parameters:

{"reasoning_effort":"low","reasoning_split":true}

Use model ID MiniMax-M3.1-Flash, not the retired anonymous ID. Reasoning is mandatory: low is not disabled reasoning. The output-token budget includes reasoning, so a small limit can truncate the answer. See the official OpenAI-compatible API reference.

Space Bunny and M3.1 Flash FAQ

Is Space Bunny MiniMax M3.1 Flash? MiniMax identifies it as an early version. Product lineage does not prove identical weights or serving behavior.

Can I still call the old Space Bunny free endpoint? Our old-ID request returned 404. OpenRouter’s released-model free listing uses a different ID and requires a fresh availability check.

Is the release better than Preview? Both passed their original basic tasks. The new edge cases exposed a low-effort money error. There was no matched same-day old-version retest, so no broad improvement percentage is justified.

Can this guide production selection? Use the concrete failure and original answers to design your own workload tests, repeated across your deployment route. Validate money, permissions and state transitions deterministically.
