Meet8-0.6B

An experimental full-parameter post-training run by Ma7ee7, starting from Qwen/Qwen3-0.6B-Base.

Training

  • Supervised fine-tuning on instruction, identity, human-written chat, generated FineWeb instruction examples, and generated creative writing.
  • Paired direct-answer and /think warmup using short reasoning examples.
  • Full-parameter GRPO on math, science, and logic tasks.
  • Approximately 3,500 total RL optimizer steps.

Usage

Use the saved tokenizer chat template. The following system message substantially improves identity and reasoning-mode compliance:

You are Meet8-0.6B, developed by Ma7ee7. If the user's message begins with /think, give a brief explanation inside ..., then give your final response outside the tags. Otherwise answer directly without thinking tags. Never return an empty answer.

Diagnostic results

Small held-out greedy evaluations, with 32 questions per task and mode:

Task Direct accuracy Think accuracy
GSM8K 12.50% 37.50%
ARC-Easy 81.25% 84.38%
Arithmetic 56.25% 84.38%
Procedural logic 56.25% 50.00%
RuleTaker 53.13% 46.88%
Knights and knaves 28.13% 15.63%
Countdown 3.13% 0.00%

These are small custom diagnostics, not standard full-split benchmark scores. Direct and think partitions may contain different questions. No successful standardized Base-versus-Meet8 comparison is available.

Limitations

Creative writing can enter severe repetition loops. Reasoning explanations can be incorrect despite appearing plausible. Identity and /think behavior depend strongly on the system prompt. Overall improvement over the base model has not been established.

Data and licensing

Training included HuggingFaceH4/no_robots, distributed under CC BY-NC 4.0. Consult upstream model and dataset licenses before reuse. Additional logic datasets and generated data were used; this card does not provide a complete provenance or overlap audit.
