Space Bunny Alpha Benchmarks: What's Been Measured

There are no official benchmark scores for Space Bunny Alpha. Neither TokenRA nor the anonymous provider has published an evaluation table, so there is no MMLU, SWE-bench or AIME number to cite. What does exist is a set of operational measurements and one independent tokenizer analysis — below is each of them, with the source of every figure labelled.

How we label sources on this page

Anonymous models attract a lot of confident numbers. We separate what the provider states from what a third party has measured from what is only a hypothesis.

Why there is no benchmark table for this model

Space Bunny Alpha is a stealth release: a lab puts a model into public testing under a codename with the provider hidden. In that arrangement there is no model card, no paper, no evaluation appendix and no vendor to publish one. The TokenRA listing contains the model specifications, while the OpenRouter listing displays live operational metrics — neither is a quality evaluation table.

This is worth stating plainly because it is the reason a search for space bunny alpha benchmarks is unhelpful right now. At the time of writing the results for that query are dominated by the model's own listing pages and by evaluations of other stealth models — Union Alpha, Ox Alpha, Horizon Alpha. Nobody has published a benchmark page for this model. That absence is the finding.

Operational metrics Listing-reported

These operational figures are reproduced from the OpenRouter listing as observed on 25 September 2026. The displayed three-day window runs from Sep 22, 10 AM to Sep 25, 10 AM. They describe gateway service operation, not model quality, and are not independent measurements by this site.

MetricValue (25 Sep 2026)What it means
Throughput80 tok/s (P50, best across providers)How fast the model writes
Latency1.05 s (P50)Total round-trip time
Uptime (3d)99.76%At least one provider was responding
Availability (3d)98.24%Inference was successfully served
OpenRouter availability (24h)98.57%Inference successfully served over the last 24 hours
PriceFreeNo charge for prompt or completion tokens

Source: OpenRouter listing, observed 25 September 2026. It defines availability as the percentage of time inference was successfully served and says it uses the next-best provider when one returns an error. The 98.24% figure is therefore a listing-reported OpenRouter gateway metric, not an independent test by this site, not a TokenRA metric, and not proof that the two routes share one upstream provider.

Independent measurements Independent

The only third-party measurement we can point to comes from stealthprint, an open-source fingerprinting toolkit (MIT licence) whose space-bunny case was published on 24 September 2026. Its method is a vocabulary differential: send the same probe text to the mystery model and to candidate tokenizers, and compare token counts. Because the probe differential cancels the chat-template constant,leaving only the model's own tokenizer count.

MeasurementResultWhat it supports
Tokenizer vocabulary (24 probes)24 / 24 matched MiniMaxThe strongest public identity signal. Same run scored Kimi 13/24 and GLM 7/24, so this is not a generic "everything looks similar" result.
Chat-wrapper overhead+143 tokens, zero driftStable serving path — the gateway template does not change between calls.
Context ceiling≥ 1M tokens (binary search)Confirms the listed 1M window is real, and rules out the older m2.5 generation.
Same-gateway deltaIdentity with minimax-m3 / m2.5Points to the same serving family as the named MiniMax models.
Vision stackAdapter-class visionImage input is real and size-scaled, not a placeholder.
Backend poolHomogeneousRepeated identical probes returned a consistent backend.
Self-identificationImprovised ChatGPT claimDeliberately weighted at zero. For stealth models the self-report is frequently bait — see the caveat below.

What these numbers are not

Every figure above is an identity measurement — it tells you which toolchain the model resembles. None of it is a capability measurement. A 24/24 tokenizer match says nothing about whether the model writes better or worse code than its named sibling. Do not read this table as a quality ranking.

Two specific traps worth naming:

What people are actually running on it Provider-listed

The listing publishes the public apps sending the most traffic to this model. This is the closest thing to a real-world workload benchmark that exists right now, and the pattern is unambiguous:

AppTokensType
Cline54.1BCoding agent (IDE)
Claude Code50.4BAgentic coding tool
Hermes Agent32.1BOpen-source autonomous agent
DeepSeek Harness30BAgent harness
Kilo Code28.9BAgentic coding tool

Every top consumer is a coding agent. Five for five, with no chat app and no consumer product in the list. That is the strongest available signal about what this model is good at: long-horizon agentic coding with large contexts, exactly the workload the 1M window and tool calling support. It is not a benchmark score, but it is measured usage rather than a claim — and it is the number we would weigh most heavily when deciding whether to build on this model.

Token volumes are cumulative and grow continuously; the ranking above is a 24 September 2026 snapshot.

How to measure it yourself

Because no official table exists, your own numbers are the only ones that describe your workload. Four steps, in order of cost:

  1. Run your own task set. Take ten real prompts from your actual use case, run them against space-bunny-alpha and against the model you would otherwise pay for, and score the outputs blind. This is the only comparison that answers your question.
  2. Measure your own latency and cost. The P50 figures above are global; your numbers depend on your region, prompt length and reasoning effort setting.
  3. Test the availability gap. Rerun your set enough times to see whether the current OpenRouter snapshot generalises to your route. Decide what your fallback is before you depend on a free preview.
  4. Reproduce the fingerprint if you want to verify identity. The stealthprint toolkit is open source: stealthprint tokenizer --tokenizers tok/ reruns the vocabulary differential with your own tokenizer files.

Our own test results are in progress and will be published on the home page as they complete. We would rather show an empty slot than a borrowed number.

Space Bunny Alpha benchmarks: FAQ

Are there official benchmark scores for Space Bunny Alpha?

No. As of 24 September 2026 neither TokenRA nor the anonymous provider has published an evaluation table. There is no MMLU, SWE-bench or AIME score to cite, so any figure quoted for this model is either inherited from another model or invented.

What has actually been measured?

Two categories. OpenRouter listing-reported operational metrics (80 tok/s P50, 1.05 s P50 latency, 99.76% three-day uptime, 98.24% three-day availability, free pricing) and one independent analysis: 24/24 tokenizer vocabulary match, +143-token wrapper overhead, and a verified context ceiling of at least 1M tokens.

How fast is Space Bunny Alpha?

The OpenRouter listing reports roughly 80 tokens per second at P50 and 1.05 seconds P50 latency in the 25 September 2026 snapshot — live operational figures that move over time, describing serving speed rather than model quality.

Does it have coding benchmark results?

None have been published. The listing claims strong coding capability, and the five heaviest consumers are all coding agents, but no coding benchmark score has been released by the provider or measured independently.
