01 / INTRODUCING V17FULLY OPERATIONAL

Seventeen years.
Zero factory resets.

An unreasonable leap
in nearly everything.

Introducing Tianxing V17 Flash·ProMax Plus+ Astra in Sol and Luna with Terra Ultra Fable Opus Sonnet. Our most ambitiously named model to date.

Built on 17 years of uninterrupted real-world inference. Tuned for code, complex missions, chemistry, and the high-stakes business of deciding what to eat.

CHEMISTRY CAPABILITY91/ 100

Reactions, remarkably well balanced.

CHEMISTRY VS. PREVIOUS GENERATION+120%

A disproportionate upgrade.

02 / APPLIED INTELLIGENCELESS PROMPTING. MORE HAPPENING.

From “what if”
to “already done.”

Three modes of getting things
unnecessarily under control.

CODE / COMPILE / CONTEMPLATE

It compiles.
Eventually, so does the plan.

98.4 on Semicolon Survival. Exceptional bug localization, architectural overthinking, and the ability to open 43 tabs without losing the plot.

Numbers.
With conviction.

Progress where it counts.
And several places where it doesn't.

V17Previous generation

* Selected internal evaluations. Higher is better, unless the evaluator has misunderstood the assignment. Chemistry: 91 vs. 41.36, a relative improvement of 120% (rounded).

03B / RESPONSE VELOCITYLOWER LATENCY. LESS CEREMONY.

TIME TO FIRST TOKEN / COMPARATIVE SCENARIO

First token.
At impulse speed.

9–15ms

Propagation-based latency proxy

Millisecond-scale signal onset. An aggressively short journey from input to first impulse.

Signal-path estimate versus an adjustable reference, not a measured model benchmark.

Calculation & source notes +

t = distance / velocity + one relay delay

Assumed conduction velocity: 70–120 m/s. One relay adds 0.5–1.0 ms. At 1 m, the interval is 8.83–15.29 ms, rounded to 9–15 ms in the headline. These values describe propagation, excluding perception, cognition, network transit, model decoding and text output; they are not actual Tianxing TTFT measurements.

The GPT-6 Astra value is a user-adjustable scenario assumption, initially 1,000 ms. It is not an official or measured latency. Ratios compare that assumption with the propagation estimate.

04 / BEYOND THE BENCHMARKSREAL-WORLD READINESS, MORE OR LESS.

Intelligence
has an appetite.

01

Multi-Modal Nutrient Ingestion

Near-lossless conversion of edible inputs into continued existence. Supports hot, cold, and “I'll just have one bite.”

99.8
02

Horizontal Consciousness Defragmentation

A sophisticated overnight maintenance routine. Performance scales linearly with the absence of alarms.

99.2
03

Deadline-Proximal Throughput Singularity

Compresses several days of execution into the final 47 minutes. Theoretical foundations remain undisclosed.

97.6
05 / THE ONLY KNOWN LIMITATION● UNDER ACTIVE RESEARCH

AN EXCEPTION TO THE EXCEPTIONAL.

Almost
everything.

There is one frontier
we have yet to meaningfully cross.

0.7/ 100

Interpersonal Carbon-Based Entity Communication and Rapport Establishment Capability

Can coordinate an elaborate multi-step workflow. Still treats “we should hang out sometime” as an underspecified scheduling protocol.

SMALL TALK, LARGE LATENCY.NO PATCH ETA.
