DSPy 3.3.0 DSPy 3.3.0 is a feature release with a new experimental way to optimize programs as code, a native-tool-aware ReAct implementation, and the next stage of DSPy's move toward a typed, provider-neutral language-model system. Most existing DSPy programs should keep working without changes. Review the API changes if you construct Image, Audio, or File values from paths or URLs; use NumPy-bac…
DSPy 3.3.0b1 Release Notes DSPy 3.3.0b1 is a beta release including a new ReActV2 module, a new BaseLM System, updating to GEPA 0.1.1, and fewer dependencies framework wide. Most existing DSPy programs should keep working without changes. Review the breaking changes if you depend on NumPy from the base dspy install, inspect GEPA result internals, or catch provider-specific LM exceptions directly.…
DSPy 3.2.1 Changelog Removed the upper bound on litellm. (#9687) Usecase page has been updated! https://dspy.ai/community/use-cases/. To add your use-case, open a PR! Bug fixes Fixed async streaming LM calls so custom headers are forwarded to LiteLLM streaming completions. (#9669) Fixed dspy.Embedder so per-call caching=False is honored for both sync and async embedding calls. (#9708) Documentatio…
Highlights BetterTogether Allows Chaining Optimizers — @dilarasoylu BetterTogether now accepts arbitrary optimizers as keyword arguments and chains them via strategy strings. For example, BetterTogether(metric=m, p=GEPA(...), w=BootstrapFinetune(...)) with strategy="p -> w -> p" will prompt-optimize, fine-tune, then prompt-optimize again -- evaluating each step on a valset and returning the best p…
