Slim model

Slim fixture: tiny_starcoder_py-mic

A 3.7M-parameter fixture for the GPTBigCode MIC, covering bigcode/tiny_starcoder_py. It is a test artifact, not a usable model, tagged test-artifact to keep it out of candidate-model search.

• Fixture key 0852b1b7488d. It covers every checkpoint whose processor files are byte-identical and whose config matches after shrinking.
• Same architecture, smaller config: GPTBigCodeForCausalLM, shrunk by the generic rule in sweep.py ().
• Processor files copied byte for byte from bigcode/tiny_starcoder_py: generation_config.json, merges.txt, special_tokens_map.json, tokenizer.json, tokenizer_config.json, vocab.json.
• Random weights (seed 17). They passed the input-sensitivity gate: every perturbation of the contract's inputs moved the logits by at least 0.001 (weakest: attention_mask:all_ones, 0.5), so no training was needed.
• Same tensor names as the real checkpoint. The real checkpoint has every parameter, and so does the fixture.
• Saved in float32, the dtype bigcode/tiny_starcoder_py loads in by default.
• Finite in float32, bfloat16, and float16 (forward, loss, gradients).

Built by build_fixtures.py; build.json records the pinned sources, gate results, and file hashes. This repository includes the slim weights, usage and framework expectations; rebuild the other files with python example/build_fixtures.py --fixture tiny_starcoder_py-mic.
