an eerie sense that something is just not right…
Between the two worlds lies The Forgotten Kingdom - home to creatures
long since thought extinct and ancient magic so strong it defies belief!
Only here can you find what has been lost for centuries: An Elixir Of
Life which will restore youth and vitality if only those who seek its
power are brave enough to face up against all manner of dangers lurking
in this mysterious land! But beware; some say there may even exist
powerful entities beyond our comprehension whose intentions towards
humanity remain unclear at best ---- they might want nothing more than
destruction itself rather then anything else from their quest after
immortality (and maybe someone should tell them about modern medicine)?
In any event though – one thing remains true regardless : whether or not
success comes easy depends entirely upon how much effort we put into
conquering whatever challenges lie ahead along with having faith deep
down inside ourselves too ;) So let’s get started now shall We?

🎯 2023/11/05: The base model of Yi-6B-200K
and Yi-34B-200K
.
This release contains two base models with the same parameter sizes of previous
release, except that the context window is extended to 200K.
🎯 2023/11/02: The base model of Yi-6B
and Yi-34B
.
The first public release contains two bilingual (English/Chinese) base models
with the parameter sizes of 6B and 34B. Both of them are trained with 4K
sequence length and can be extended to 32K during inference time.

While benchmarking open-source models, we have observed a disparity between the
results generated by our pipeline and those reported in public sources (e.g.
OpenCompass). Upon conducting a more in-depth investigation of this difference,
we have discovered that various models may employ different prompts,
post-processing strategies, and sampling techniques, potentially resulting in
significant variations in the outcomes. Our prompt and post-processing strategy
remains consistent with the original benchmark, and greedy decoding is employed
during evaluation without any post-processing for the generated content. For
scores that were not reported by the original authors (including scores reported
with different settings), we try to get results with our pipeline.
To evaluate the model's capability extensively, we adopted the methodology
outlined in Llama2. Specifically, we included PIQA, SIQA, HellaSwag, WinoGrande,
ARC, OBQA, and CSQA to assess common sense reasoning. SquAD, QuAC, and BoolQ
were incorporated to evaluate reading comprehension. CSQA was exclusively tested
using a 7-shot setup, while all other tests were conducted with a 0-shot
configuration. Additionally, we introduced GSM8K (8-shot@1), MATH (4-shot@1),
HumanEval (0-shot@1), and MBPP (3-shot@1) under the category "Math & Code". Due
to technical constraints, we did not test Falcon-180 on QuAC and OBQA; the score
is derived by averaging the scores on the remaining tasks. Since the scores for
these two tasks are generally lower than the average, we believe that
Falcon-180B's performance was not underestimated.
