DSPy 3.4.0 DSPy 3.4 introduces Jev integration through TypeSafe, with three experimental decision types—Noul, Choice, and Score—that bring probability evidence into ordinary DSPy signatures. ReAnchor calibrates those decisions against your program's metric. This release also introduces native LM engines, a local CPython interpreter for trusted code, async ReActV2, and versioned documentation. pip…
DSPy 3.4.0 Beta 1 DSPy 3.4.0b1 is the first beta of 3.4. It moves language-model execution to a shared engine interface, adds a local CPython interpreter for trusted code, and brings async execution to ReActV2. It also adds custom Flex code proposals in GEPA and fixes evaluation, streaming, and demonstration-sampling bugs. This is a prerelease, not the stable 3.4.0 release. APIs and behavior may c…
DSPy 3.3.1 DSPy 3.3.1 contains many interpreter fixes and improvements. It makes PythonInterpreter easier to install, substantially strengthens sandbox isolation and request handling, and adds end-to-end visibility into interpreter execution. The release also improves optimizer throughput, adapter correctness, and MCP compatibility. Highlights PythonInterpreter: Managed Runtime, Hardening, and Lif…
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…
