SERA GLM-5.2 Django SWE-Agent - RAW T1 (first rollout, thinking enabled)
258 raw, pre-postprocess first-rollout trajectories with native GLM-5.2 reasoning traces, from the SERA SVG pipeline (paper).
Released raw so you can choose your own filtering, verification threshold and reasoning-trace handling. Companion: SERA-GLM5.2-Django-SWEAgent-Raw-T2.
Schema
Mirrors allenai/Sera-*-T1/T2:
| column | notes |
|---|---|
messages |
JSON string - apply json.loads(). Raw SWE-agent history: role, content, thought, action, tool_calls, thinking_blocks |
instance_id |
<source>__<django instance> |
rollout_patch |
patch produced by this rollout |
target_patch |
T2 only: the first-rollout patch used as the soft-verification reference |
func_name, func_path |
the sampled starting function |
problem_statement |
T1: the vague bug prompt. T2: the synthetic PR issue |
docker_image |
SWE-bench container |
exit_status, is_good_patch, num_agent_steps |
filtering aids (is_good_patch = the T1 LLM grader verdict) |
Reasoning traces
Generated with GLM-5.2 extended thinking enabled (thinking: {type: enabled, budget_tokens: 8000}, temperature: 1.0). Unlike the official SERA releases - where the teacher wrote its reasoning inline and content already contains <think>...</think> - here the two channels are separate:
content- the short outward-facing line ("I'll start by examining...")thinking_blocks- the actual deliberation (median ~1.1k chars, up to ~47k)
Wrapped into <think> tags, these traces are richer than the official release:
| data | median | p90 | max |
|---|---|---|---|
official SERA-4.6-Lite-Best-Subset |
124 | 1006 | 3999 |
| this dataset | 159 | 3217 | 39890 |
Caveat - empty turns. GLM only deliberates when a step is non-trivial; ~21% of assistant turns carry a thinking block, and ~25% of turns have neither text nor thinking (just a tool call). A naive add_think wrapper turns those into hollow <think></think>, which teaches the student to skip reasoning. Either drop the tags on such turns or backfill from action. (This artifact is not specific to thinking mode - it is present in non-thinking SERA-style data too.)
Turning this into training data
SERA's postprocess (sera/datagen/data/postprocess/) converts these to hermes/xml chat records, but out of the box it reads only content - to use the native traces, prefer thinking_blocks when populated. Soft verification is recomputable at any threshold from rollout_patch vs target_patch (line-level recall), so no regeneration is needed to change r.
Generation config
Teacher GLM-5.2 via an Anthropic-Messages gateway; harness SWE-agent (str_replace_editor, bash, submit); SWE-bench Django container django__django-7530 (base f8fab6f9); 115-step cap; SERA soft-verified generation (SVG). Non-thinking companion runs will be released separately.
