dspy-lite 3.2.1.post1

DSPy with litellm replaced by litelm and numpy made optional

dspy-lite

DSPy with litellm replaced by litelm and numpy made optional.

What this is

• Same DSPy 3.2.1 -- signatures, modules (Predict, CoT, ReAct), optimizers (Bootstrap, MIPRO, SIMBA, GEPA, GRPO)
• litellm (100k+ LOC, 70+ transitive deps) replaced by litelm (2.6k LOC, 2 deps)
• numpy moved from core dep to optional [embeddings] extra
• 83% smaller clean install (24 MB vs 144 MB, 36 packages vs 67)
• Unaffected by the litellm supply chain compromise (CVE-2026-33634) — zero litellm code or dependencies

Install

pip install dspy-lite

With provider extras:

pip install dspy-lite[anthropic]     # Anthropic
pip install dspy-lite[bedrock]       # AWS Bedrock
pip install dspy-lite[embeddings]    # numpy for embeddings
pip install dspy-lite[all]           # everything

Usage

import dspy

lm = dspy.LM("openai/gpt-4o-mini")
dspy.configure(lm=lm)

predict = dspy.Predict("question -> answer")
result = predict(question="What is DSPy?")
print(result.answer)

Everything from DSPy works -- the import is still import dspy.

What changed from DSPy

numpy	core dep (60 MB)	optional [embeddings]
Clean install size	144 MB, 67 packages	24 MB, 36 packages

Development disclosure

This project is maintained with AI-assisted coding. Through 2026-05-14, I used Claude Code with Claude Opus 4.6/4.7. As of 2026-05-14, I use pi with GPT-5.5. The human maintainer remains responsible for what is merged and released.
