The anonymous Stealth model on OpenRouter had a 1M context, a 524,288-token output cap found on no other model, and no lab behind it. Here is the evidence for MiniMax M3.1-Flash-Preview, the counter-case, and how to fingerprint a stealth model yourself.
Meta published the Muse Gadget SDK on 2 October 2026: open-source firmware that turns a $12 ESP32 board or a spare Raspberry Pi into a device your Muse agent can drive. The 24 supported boards, real costs, and the clause that caps it at 50 free units.
Alibaba added three Qwen3.8 SKUs in September with no launch post. Max-Prime is a higher-throughput serving tier at double the price, not new weights. Omni-Flash accepts audio and video but returns text only, at Flash pricing. Full lineup, pricing and licence tables.
Z.ai added GLM-5.3 Prime and GLM-5.3 FlashX in September 2026. Neither is a new model — both are accelerated serving tiers of weights that already shipped. Here is the full GLM-5.3-era lineup, with verified prices, licences and a decision rule.
Verified Grok 4.7 API pricing: $2 input and $6 output per 1M tokens, doubling at 200K prompt tokens, plus server-side tool fees and worked monthly cost examples.
GPT-6 Luna costs $0.10/1M input and $0.50/1M output with a 1,050,000-token context window - exactly half the price of GPT-5.6 Luna. Full specs, independent benchmarks, the 272K pricing cliff, and whether to migrate.
Everything Meta announced for Muse at Connect 2026: the Muse Charm keychain, the Muse Realtime Avatar model (448x768 at 25fps, ~870ms), Realtime Voice, Mac computer use, glasses, connectors, Muse for Small Business and the Meta Enterprise Platform.
Run Qwen-Image-2.1 locally on 8-24GB GPUs: official ComfyUI files, GGUF quants for low VRAM, and the Diffusers pipeline. Includes a VRAM table, transparent PNG and multi-reference editing, the vendor benchmark, and the non-commercial license caveat.
Claude Sonnet 5.5 and GPT-6.1 Sol launched a day apart at the same $2/$10 price. Sonnet leads Artificial Analysis's Intelligence Index v4.3.2 56.00 to 51.83; Sol costs $0.72 per task vs $7.67. Benchmarks, caching, long-context pricing and a worked cost example.
Sonnet 5.5 costs half of Opus 5.5 per token and nearly matches it on benchmarks, but uses ~60% more output tokens — $7.67 vs $5.98 per task at max effort on Artificial Analysis v4.3.2. Benchmarks, a per-task cost worked example, and a task-by-task pick table.
GPT-6.1 Sol launched 29 Sep 2026: $2/$10 per 1M tokens, $0.10 cached input, 1.05M context. Specs, 272K pricing rules, benchmarks vs GPT-6 Astra, GPT-6 Sol and Claude, and a Responses API quickstart.
MiMo-V2.6-Flash is Xiaomi's MIT-licensed 309B/15B-active MoE at $0.14/$0.28 per 1M tokens. The Distill-Qwen-9B runs on an 8 GB GPU. Specs, benchmarks, VRAM by quant, and Ollama / LM Studio / llama.cpp commands.
Claude Sonnet 5.5 (Sept 28, 2026): $2/$10 per 1M tokens, 1M context, 128K output, API ID claude-sonnet-5-5. Benchmarks vs Opus 5.5 and GPT-6 Sol, Python quickstart, and the five breaking changes from Sonnet 5.
Grok 4.7 explained: the grok-4.7 model ID, 500k context, $2/$6 pricing with the 200k tier and Fast variant, xAI vs Artificial Analysis benchmarks, API quickstart, availability and who should use it.
Grok 4.7 vs Grok 4.6: same $2/$6 price and 500K context, a new larger base model, +17 points on Terminal-Bench, but ~2.25x the tokens per task. Specs, benchmark deltas, real cost per task, API migration, and the Grok 4.8 outlook.
Claude Opus 5.5 and GPT-6 Sol launched 90 minutes apart on 22 Sept 2026. Opus 5.5 wins on benchmarks; Sol costs half per token. Pricing, cost per task, shared benchmarks, Claude Code vs Codex, and which to pick.
Migrating from Claude Opus 5 to Opus 5.5: thinking can't be disabled, forced tool_choice returns 400, thinking blocks are bound to the conversation, computer_20251124 is rejected, and effort defaults to medium. Exact errors, before/after code, costs, and a rollback plan.
GPT-6 Sol ($2/$10) and GPT-6 Luna ($0.10/$0.50) launched 22 Sept 2026 at half the price of GPT-5.6. Specs, model IDs, pricing, OpenAI vs independent benchmarks, availability, API code, and Sol vs Astra.
Claude Opus 5.5, GPT-6 Astra and Grok 4.7 compared on list, cache and long-context pricing, context windows, shared benchmarks, Artificial Analysis cost per run, and availability, plus a decision table by workload.
DeepSeek-V4.1-Flash (10 Sept 2026): 552B MoE with 8B/16B active, 1M context, MIT weights, $0.30/$1.20 per 1M peak. Why V4-Pro was not deprecated after all, what the 90.6 Terminal-Bench score really means, and what running it locally takes.
Meta Muse is Meta's personal AI agent app, launched 8 Sept 2026 on Muse Spark 1.3. What it does, how the Secure VM and Sentinel work, pricing, Muse for Mac, Muse Connectors, privacy, and how it compares with Claude Cowork and Gemini Spark.
Claude Opus 5.5 launched 22 September 2026: model IDs on every platform, 1M context, $4/$20 pricing vs Opus 5 and Fable 5.1, the new medium effort default, full benchmark table, Artificial Analysis ranking and its token-usage catch, and system-card safety notes.
Xiaomi's MiMo-V2.6-Pro is the new top open-weight model: 1.02T/42B MoE, 1M context, MIT licence, AA Index 46, $0.435/$0.87 API. Specs, benchmarks, hardware, comparison with Kimi K3, Qwen 3.8 Max, DeepSeek V4.1 Flash and GLM-5.3.
GPT-6 Astra beats GPT-5.6 Sol by 5.7 points on Artificial Analysis's Intelligence Index v4.3.2 (52.67 vs 46.97 at max effort) and costs 64% more per task. But Sol is now deprecated on AA, and GPT-6.1 Sol reaches 51.83 for $0.72 a task.
GPT-6 Astra lists at exactly twice Claude Opus 5. On the one independent same-harness index that has run both, Opus 5 scores higher. Here is the full cost and benchmark breakdown.
