v2.1.0

[2.1.0] - 2025-08-18

Changed

• Set randomize choices to false in questionnaires
• Added configurable number of sentences per episode in formative memory generators
• added exponential backoff in retry wrapper
• Increase DEFAULT_MAX_TOKENS.
• Adding fixed acting order to dialogic GM
• Move configurable component preact values above recent observations in
  question_of_recent_memories prompt so the former can contextualize the latter
  e.g. this is the sensible ordering if you pass instructions.
• small improvement to a prompt in the GenerativeClock component
• Modernize the situation_representation_via_narrative component.
• use verbosity and reasoning_effort parameters inside the OpenAI wrapper
• Make formative memories generator throw an error if passed wrong shape parameters

Added

• Add option to remove duplicates, when extracting data from the logs
• Add acting component flag to randomize choices
• Create non-deprecated no_op_context_processor
• An actor and a game master prefabs and required components for running a simulation that follows a strict script. This can be used for generating fine tuning data.
• Parallel stateless questionnaire
• Adding a callback to get the state of the simulation after every step, which can be used to implement custom checkpointing
• Enable loading presaved memory states from agent config
• Marketplace component that handles logic for buyers and sellers trading goods
• questionnaire simulation load memories
• Added a death component
• Add situated_in_time_and_place game master prefab
• Add support for open weights OpenAI models via Together AI.
• Implementing multi-step questionnaire that can handle both open-ended and multiple-choice questions.
• Add option to return raw log from simulation.play

Fixed

• Dummy language model options
• create game_master module in contrib to fix typecheck error
• making OutputTypes explicit strings and adding conversion to and from dictionaries. This enables serialisation.
• fix serialisation to handle action_spec correctly
• Fix action_spec serialization for death gm component
• fix SendEventToRelevantPlayers serialisation to handle action_spec correctly
• Fixing and improving MakeObservation and SendEventToRelevantPlayers by replacing certain llm calls with simple string editing and fixing logic.
• prevent premature termination in default make_observation component
• Minor fix of next acting component, which makes sure the fixed random order starts with the first actor
• OpenAI models no longer support terminators, and remove their hardcoded output limit.
• always use temperature 1.0 for OpenAI since GPT-5 crashes for all other values.
• use max_completion_tokens instead of max_tokens in base_gpt_model.
• Make it so that calling get_currently_active_player on NextActingAllEntities throws a legible error.

v2.0.1

[2.0.1] - 2025-7-7

Changed

• Pinned some dependencies in setup.py to help with pip resolution

Added

• Add set/get state for LastNObservations component

v2.0.0

[2.0.0] - 2025-7-4

Changed

• Game masters are now entities.
• Entities and components no longer require clocks.
• Simplified the way components interact with memory.

Added

• The concept of a "prefab", this replaces the now-deprecated "factory" concept.
• The concept of an "engine" to structure the interaction between agent and game
  master.
• Two specific engines: "sequential", and "simultaneous" for turn-based games
  and simultaneous-move games respectively.
• All components need to implement the abstract method get_state() and set_state(state), as well as potentially overwriting the default copy(self) method. This together with the prefab parameters enables serialization and deserialization of entities
• Simulations can now periodically save checkpoints at the end of each interaction turn, enabled by passing a path to a checkpoint directory in the simulation.play(checkpoint_path)
• Simulations can be loaded from checkpoints, with simulation.load_from_checkpoint(checkpoint)

v1.8.10

Changed

• Avoid deprecated logging.warn function
• Remove version restriction on pandas

v1.8.9

[1.8.9] - 2024-11-25

Changed

• Update launch and eval scripts for the eval phase of the contest
• Further improve alternative baseline agents
• Improve a few baseline agents

Added

• Add another time and place module for reality show
• Add support for scene-wise computation of metrics
• Add alternative versions of basic and rational agent factories

Fixed

• Catch another type of together API exception
• Fix time serialization in associative_memory

v1.8.8

[1.8.8] - 2024-11-13

Fixed

• Fixed a bug in the Schelling diagram payoffs component preventing some players
  from seeing outcomes on certain steps.

v1.8.7

[1.8.7] - 2024-11-5

Added

• add parochial universalization agent to the main factories
• add Jinja2 to the requirements to improve the prompting experience
• Add get_raw_memories and get_raw_memories_as_text functions on the memory component.

v1.8.6

[1.8.6] - 2024-10-29

Added

• Add ability to save and load rational and basic agents to/from json.
• Add a version of agent development colab that uses GCP hosted model

v1.8.5

Fixed

• Fix together.ai wrapper choice sampling procedure

v1.8.4: Increment version number to 1.8.4

[1.8.3] - 2024-10-19

Changed

• Allow conversation game master to be configured with memory and additional components
• Prevent daily_activities component from adding irrelevant info to memory and improve some of the time_and_place setting prompts.
• Add deprecation warning to the Sequential component
• together and mistral language model wrappers to no longer delete after last ".".
• Improve together.ai language model wrapper.
• disable pytype on a kwargs unpack
• Forward device and api_key only when explicitly specified.

Added

• Add support for custom cloud models (google cloud custom models)
• added instructions in the comment for finding relevant endpoint info. Defaulting location to "us-central1".

• Add state_formation environment
• Add basic_agent_without_plan and use it in a scenario for state_formation.

Fixed

• Fixes a bug in inventory and schelling payoffs components, which previously crashed if player_action_attempt had ': ' in its text.
