Introduction

We're introducing GLM-5.2, our latest flagship model for long-horizon tasks. It marks a substantial leap in long-horizon task capability over its predecessor GLM-5.1 and, for the first time, delivers that capability on a solid 1M-token context. GLM-5.2's new capabilities include:

Solid 1M Context: A solid 1M-token context that stably sustains long-horizon work
Advanced Coding with Flexible Effort: Stronger coding capabilities with multiple thinking effort levels to balance performance and latency
Improved Architecture: We propose IndexShare, which reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9× at a 1M context length. We also improve GLM-5.2’s MTP layer for speculative decoding, increasing the acceptance length by up to 20%
Pure Open: An MIT open-source license — no regional limits, technical access without borders

Footnote

Humanity’s Last Exam (HLE) & other reasoning tasks: We use sampling parameters of temperature=1.0, top_p=0.95 for evaluation. We evaluate with a maximum generation length of 163,840 tokens. By default, we report the text-only subset; results marked with * are from the full set. For AIME, HMMT and IMOAnswerBench, we evaluate each question using the following system prompt: Your response should be in the following format:\nExplanation: {your explanation for your final answer}\nExact Answer: {your succinct, final answer}\nConfidence: {your confidence score between 0% and 100% for your answer}. We use GPT-5.5 (medium) as the judge model. For HLE-with-tools, we use a maximum context length of 300,000 tokens, with no context management strategy.
SWE-Bench Pro: We run the SWE-Bench Pro suite with OpenHands using a tailored instruction prompt. Settings: temperature=1, top_p=1, max_new_tokens=32k, with a 400K context window.
NL2Repo: We evaluated NL2Repo with temperature=1.0, top_p=1.0, and max_new_tokens=48k under 400k context. To prevent hacking, we use rule-based and a LLM-based judgement to prevent malicious behaviors (e.g., unauthorized pip or curl operations).
DeepSWE: We run DeepSWE with the official pier evaluation framework and the mini-swe-agent harness (temperature=1.0, top_p=1.0, timeout=2h, 400K context). Each task is solved in an isolated container with 2 CPUs, 8 GB RAM, and no internet access.
ProgramBench: We evaluate ProgramBench (200 instances) with Claude-Code 2.1.156 using temperature=1.0, top_p=1.0, max_tokens=64000, max_turns=2000, sample_timeout=6h, reasoning_effort=max, with a 400K context window. Each instance runs in a (4 CPUs, 8 GB RAM) sandbox with internet access disabled.
Terminal-Bench 2.1 (Terminus 2): We evaluate Terminal-Bench 2.1 with Terminus-2 framework using parser=json, timeout=4h, temperature=1.0, top_p=1.0, max_new_tokens=48k, max_episodes=500, with a 256K context window. Resource limits are capped at 4 CPUs and 8 GB RAM.
Terminal-Bench 2.1 (Claude Code): We evaluate in Claude Code 2.1.167 with temperature=1.0, top_p=0.95, max_new_tokens=131072. We override max_new_tokens to 128k via a transparent proxy, bypassing the 64k CLI cap to restore the configurability of CLAUDE_CODE_MAX_OUTPUT_TOKENS. We remove wall-clock time limits, while preserving per-task CPU and memory constraints. Scores are averaged over 5 runs.
MCP-Atlas: All models were evaluated in think mode on the 500-task public subset with a 10-minute timeout per task. We use Gemini-3.0-Pro as the judge model for evaluation.
Tool-Decathlon: We use the official evaluation service and set max_token to 128K.
FrontierSWE: The evaluation was conducted by Proximal with 1M context length, max effort level, and 128K maximum output tokens. Dominance score reported as of 2026/06/16.
PostTrainBench: The evaluation was conducted by PostTrainBench with 1M context length, max effort level, and 128K maximum output tokens.
SWE-Marathon: The evaluation was conducted by Abundant AI with 1M context length, max effort level, and 128K maximum output tokens.
